Due to the in- herent advantages of NOR-HALS techno- logy, the stabilizers have a lower interac- tion with system components and acidic environmental contaminants than tradi- tional HALS products, thereby helping to retain the mechanical properties of TPO membranes to meet the demands of building owners. Heat and UV exposure are two of the ➠ BASF Plastic Additives 巴斯夫塑料添加剂 www.plasticadditives.basf.com K 2019: Hall 5, Booth C21 – D21 5号展厅，C21 – D21展位 most detrimental factors affecting the useful life of roofing membranes today. Manufacturers need to fulfill the new ASTM D6878 standard for TPO roofing formulations. These standards identify the minimum levels of exposure to heat and UV levels that a TPO membrane must be able to withstand. By using BASF’s plastic additives technology, Won- poong succeeded in winning the con- tract over other companies by receiving a better evaluation for weatherproofing. Energy issues are growing in importance in the selection of all building materials, and roofing is no exception. Factoring in overall energy performance as part of a system’s life-cycle cost, many customers and contractors are insisting on TPO roofing membranes as they are heat-re- flective. Energy efficient roofing systems can reduce a building’s internal cooling costs dramatically.
