ASA PVC Corrugated roofing has the advantages of light weight, convenient installation, rich colors, beautiful appearance, anti-aging, non fading, long life and so on. The thermal insulation effect is significant. How many degrees of high temperature can the synthetic resin roofing as a new environmental protection building material resist?
ASA PVC roofing is pre-plasticized with ASA resin plus PVC resin at a high temperature of about 180 degrees. After cooling and molding, the product will be deformed due to high temperature at 70-80 degrees Celsius. Not suitable for factory building surfaces in high temperature industries such as smelting and casting.
In between minus 30 degrees and 70 degrees Celsius, Polyvinylchloride molecular interstitial structure will thermal expansion and contraction changes due to temperature contrast. Poor quality synthetic resin roofing will burst when they encounter snow in lower temperature areas. Therefore, the design of the pitch of the purlins of the synthetic resin roofing is controlled to be about 66cm to 75cm, so as to prevent the synthetic resin roofing from sagging or bulging due to thermal expansion and contraction, which reduces the waterproof effect.
