BASF's Chimassorb® light stabilizer has been listed as a standard solution
for thermoplastic polyolefin (TPO) roofing membrane by waterproofing material researchers from the China Academy of Building Materials Sciences.
TPO roofing membrane can be used as an alternative to asphalt membrane, which is laid on a flat roof to protect the building from damage caused by the impact of heavy rain
.
However, like all polymers, TPOs degrade prematurely when exposed to UV radiation and high temperatures, with small cracks that reduce wind resistance
.
Chimassorb® light stabilizers provide weatherability and long-lasting strength, ensuring UV resistance of polymers, improving roof durability and creating longer-lasting, longer-lasting products; Helps to conserve resources and reduce the pressure
caused by waste disposal.
