Are you looking for an ideal roof material? It seems likely that you are looking for a lightweight, excellent impact strength and durable glazing solution. Polycarbonate sheets are you fantastic alternative. There are usually three types of polycarbonate widely used for roof, solid polycarbonate multi wall polycarbonate and corrugated polycarbonate panels.Polycarbonate sheets are manufactured with Sabic Lexan raw polycarbonate, 250 times stronger than glass. Polycarbonate is as transparent as glass and transmit approximately 85% of sunlight. Polycarbonate can withstand extreme weather and fire. Polycarbonates can maintain rigidity up to 140°C and toughness down to -20°C or, with special grades, even lower. The material is amorphous, therefore it displays excellent mechanical properties and high dimensional stability. Unique Plastics company is a leading polycarbonate manufacturer in China with best price.We also offer customized service. OEM &ODM What are types of polycarbonate sheets?The solid polycarbonate is tough and high transmission. Polycarbonate possesses impact resistance 250 times greater than that glass while also exhibiting exhibiting tensile resistance. With UV protection on the both sides, polycarbonate can withstand even the harshad of environments and extreme temperatures. There are also embossed and diamond polycarbonate which are popular for decoration gate.These features allow them to be used in a wide range of indoor and outdoor applications,such as balcony roof, door awning, carport,sign faces and highway noise barrier.The multi wall polycarbonate sounds like layered polycarbonate sheeting that is even more powerful in terms of durability lightweight and versatility. Polycarbonate sheet is most widely used for all kinds of roofing systems, swimming pool enclosure,stadiums skylight, greenhouse cover. Multi wall polycarbonate combines light weight and outstanding flexibility which is convenience of storing, transporting and cutting. These sheets are available from twin wall to five walled structures that vary the thermal insulation and thus, application used in.Corrugated polycarbonate are even stronger and cost-effective glazing solution. Corrugated panels have many advantages as the surface of these sheets can be bent or folded into our desired designs by marketing easier to fit pieces for roofing sheets. It has superior performance with exceptional impact resistance. It allows 80% natural light into while against harmful UV rays. They can be easily bent into whichever shape required and can be layered on top of other sheets.Waved polycarbonate can be used for warehouse roof, factories roof,vertical glazing, buildding cladding.What are applications of polycarbonate?Warehouse, factories roofConversatory coverCanopiesPergola roofBalcony door awningCarport shedBuilding claddingDecoration parititonsWalkway roofHighway noise barrierSignageAcrylic VS Polycarbonate Acrylic and polycarbonate both are familiar cover material and incredibly tough completely clear. Many people are confused about how to choose suitable material. They have some key differences that you should understand as you select the right material for your project.Impact strength Polycarbonate sheets has greater impact strength than acrylic, 35 times stronger than acrylic. Polycarbonate panels are virtually unbreakable. If you are prepared for warehouse roof, we recommend you choose polycarbonate sheets. Polycarbonate can also be safely drilled anywhere on the sheet with a
standard bit and suffers no damage, whereas acrylic becomes more and
more likely to break when drilling closer to the corners. Temperature and fire resistancePolycarbonate has wide temperature range from -40℃-+120℃. Even in extreme enviroments, the pgysical featurers of polycarboante still stable. While the melting point of the acrylic sheet is 70°C. Prolonged sunlight exposure will melt the acrylic sheet. Anti-agingThere are 50um UV protection layer on the side of polycarbonate, against 99.9% harmful UV rays. Over 10 years, polycarbonate won't go aging. While acrylic sheets are easy go aging and yellowing. Polycarbonate’s optical clarity and UV resistance makes it ideal for applications such as machine guards, signs, face shields, skylights, POP displays.
Why anti-fogging polycarbonate is popular for conservatory?The reason why polycarbonate agricultural anti-fogging polycarbonate sheets can be used in a large number of conservatory covering materials is that it has high-quality light transmission, aging resistance, impact resistance, light weight, easy processing, good heat preservation and other properties. It has better performance than any lighting material in the world at present-(anti-fogging effect), whether it is glass or film greenhouse, it is inferior. What is polycarbonate sheet with anti-fogging technology ?Polycarbonate sheet with anti-fogging is useful for greenhouse.The temperature difference between indoor and outdoor will cause water vapor to condense on the walls and ceilings in the greenhouse, forming small fog droplets, reducing the light transmittance, due to further condensation, they will drip down and harm plants, use Plant green leaves turn yellow, anti-fog drop. In addition to all the excellent performance of ordinary twinwall polycarbonate , this polycarbonate can also prevent fog drop. The inclined surface (in the direction of the ribs of the plate) slides to the edge instead of directly dripping, so as to achieve the effect of anti-fog drop, reduce the crop diseases in the room, improve the light transmission performance, etc., all have significant advantages and are greatly welcomed by growers Therefore, it has become the first choice for the construction of new greenhouses and the replacement of light-transmitting covering materials for old greenhouses, and is widely used in greenhouse projects. How to distinguish the quality of anti-fogging polycarbonate? However, the quality of this agricultural anti-fogging polycarbonate is mixed, and the fish eyes are mixed, which increases the difficulty for users to identify the authenticity. The anti-fog does not have a grower and also causes huge joint economic losses, which triggers various legal proceedings. The number of cases is also increasing. How to distinguish the quality of anti-fogging polycarbonate? Choosing cost-effective products has become a problem that everyone must consider. At present, most of the friends in the greenhouse circle choose to introduce friends and some older brands. They would rather spend more money than buy a product that you can use with confidence. I also use this idea. Generally, I pay less attention to the effect of anti-fog drop. As long as it is an anti-fog drop polycarbonate sheet, ten-year quality assurance is enough, but what are the advantages of such big brands as GE? Why is it more expensive than domestic ones? It is because the anti-fog dripping boards produced by some small domestic factories are coated with silica gel and washing powder, and the effect is completely gone in about a year, including some PC board companies that are relatively influential in the greenhouse. The anti-fog dripping oil they imported is all added with distilled water, the ratio of 1:1, the effect can be imagined. And brands such as GE, Bayer, Jaspo and other brands use co-extrusion technology to squeeze into the surface of the sheet during production, and it has already formed an integral body with the sheet, and its effect will not be used for 10 years or more. There is a qualitative problem. How to identify the anti-fog drop effect? How to identify the anti-fog drop effect? According to the agricultural industry standard of the Ministry of Agriculture of China, TSO8296-1987, GB/T14216-1993, plastic wetting tension test method: ASTMD5725-95, test method, this test is judged from surface tension and contact angle. The most intuitive and simple test method is the stop drop area judgment method, the beaker test method, and the fog drop time test method.Now introduce the beaker test method, how to compare the anti-fog drop PC board, the anti-fog effect is good or bad, prepare 2 beakers, 2 anti-fog boards from different companies, fill the 2 beakers with 90% boiling water, and then The anti-fog drip board of different companies has the anti-fog side, put it on the beaker, pay attention to the change of the plate fog, the anti-fog effect of the product is good and bad, it is obvious, don't know, you can see the result. (Result: The smaller the condensation time and the coverage area, the better, or the shorter the time for the condensation droplets to fall, the better the anti-fog drop performance, the faster the sheet fogging time, the worse the anti-fog effect)
what's a curtain wallA curtain wall is the building's exterior wall enclosure, does not bear the weight, is a modern large and high-rise buildings commonly used with decorative effect of the lightweight wall. It is now mid-to-late August, and autumn has entered, and some large shopping malls and office buildings will soon face the problem of heating in winter. The contrast between two different materialsNowadays, most buildings use glass curtain walls. Although glass curtain walls are very popular, they have a natural disadvantage in heating compared with building curtain walls made of Polycarbonate.The heat transfer coefficient of glass is relatively high. If glass curtain walls are adopted, a large amount of indoor heat is easily lost in the building. In this case, it may consume more energy and spend more money on heating, which undoubtedly increases operating costs. However, a Polycarbonate sheet has a natural advantage for heating.The polycarbonate curtain wall has a low heat transfer coefficient (K value), only 1.1-4.1W/m2℃, and its thermal insulation performance is 7 to 25% higher than that of a glass of the same thickness. The lower heat transfer coefficient of the Polycarbonate sheet can reduce the transmission of indoor and outdoor temperature, so as to achieve good indoor heat preservation and reduce energy consumption. It can be said that it achieves the dual purpose of heat preservation and energy saving and environmental protection at the same time.Other advantages of PC hollow sheet curtain wall■Hilproof and windproofLarge shopping malls, office buildings, and other places have a large flow of people, and buildings have the mission of ensuring public safety and resisting natural disasters. Polycarbonate hollow sheet has super impact resistance, which is 250 times that of a glass of the same thickness, 30 times that of plexiglass, and 20 times that of tempered glass. It can resist hail, typhoons, man-made collisions, and other accidental damage to the building. A multiwall polycarbonate sheet is undoubtedly a curtain wall material that can ensure the safety of personnel better than glass.■ Flame retardant and fireproofThe flame-retardant grade of multiwall polycarbonate sheet is flame-retardant grade B. Its ignition point is as high as 580℃. It has the characteristics of self-extinguishing after leaving the fire. At the same time, it will not produce toxic gases when it burns, and it will not contribute to the spread of fire. This level of fire performance is more suitable for crowded places such as shopping malls and office buildings and meets the safety requirements of public places.■ Adequate daylighting to save energyThe PC hollow sheet has strong light transmittance, a large amount of sunlight comes in, which can reduce the use of lights in office buildings, shopping malls, and other places, and achieve the purpose of saving energy. The light transmittance of a multiwall polycarbonate sheet is 23-80%, and its light transmittance can be adjusted according to the actual application and color of the board. Generally speaking, using multiwall polycarbonate sheet as the exterior wall of the building can not only ensure a beautiful appearance, but also ensure an excellent Office and shopping experience.■ Various colors and strong fashionNowadays, most office buildings and shopping malls have very unique designs, and the color of the PC hollow sheet can be customized to meet the colors required by any design scheme. Undoubtedly, the characteristics of PC panels are more favored by builders.■Cost-effectivePC sheet has the above advantages, but multiwall polycarbonate sheet price is far lower than that of glass, and its installation and maintenance cost is also much lower than that of glass. It is a cost-effective building material.
