BASF Light Stabilizer Improves Durability of China TPO Roof Waterproof Coil

Shanghai, China - December 6, 2018 - China Research Institute Suzhou Waterproof Building Materials Academy (referred to as the Suzhou waterproof Institute) is China's leading research centers waterproof material, the Research Institute recently the BASF light stabilizers of the Chimassorb ^® The agent is included in the standard scheme for thermoplastic polyolefin (TPO) roof waterproofing membranes. As an alternative to asphalt coils, TPO roofing membranes are typically laid on flat roofs to protect buildings from the effects of heavy rain.

TPO roof waterproofing membranes are increasingly popular for their superior performance and ease of installation. However, like all polymers, TPO degrades prematurely when exposed to ultraviolet (UV) radiation and high temperatures, exhibits small cracks, loses tensile strength and elongation at break, and thus reduces wind resistance. The use of light stabilizers can alleviate this problem. Ultraviolet light stabilizers such as Chimassorb can play a particularly important role because they provide weatherability and long-lasting strength, which increases the durability of the roof. Such stabilizers also need to be compatible and can be used in conjunction with all other formulation ingredients.

Hermann Althoff, global senior vice president of the Asia-Pacific Specialty Chemicals Division at BASF, said: "Light stabilizers are critical for TPO roofing membrane manufacturers because the service life of roofing membranes is highly dependent on Whether or not a suitable UV stabilizer is used. Our stabilizer solutions can help extend the life of the product and help reduce the environmental impact of the product compared to less durable products. Helps save resources and reduce the pressure from waste disposal."

TPO roofing membranes are easy to recycle and reuse because they can be melted, purified and re-extruded. Therefore, the old TPO waterproofing membrane can be recycled to recreate a new TPO waterproofing membrane.

Mr. Wang Wenbin, R&D Manager of Suzhou Waterproof Research Institute, said: “Because the TPO roof waterproofing membrane needs to withstand the impact of bad weather on the building, any degradation will lead to water leakage and damage. Chimassorb-based stabilizer technology can ensure polymer resistance. UV capability to provide customers with more durable products."

BASF's range of light stabilizers includes UV absorbers that protect polymers from UV radiation and hindered amine light stabilizers that remove free radical intermediates formed by photooxidation.
