Title:
POLYMER COMPOSITE WITH LOW VOC EMISSION
Document Type and Number:
WIPO Patent Application WO/2024/087056
Kind Code:
A1
Abstract:
A thermoplastic composition includes at least one thermoplastic resin such as polybutylene terephthalate (PBT), polyethylene terephthalate (PET), a thermoplastic polyester elastomer (TPEE), or a combination of two or more of these; an additive that is a weak acid containing phosphorus elements such as a dihydrogen phosphate salt; and optionally an inorganic filler such as a reinforcing fiber. The thermoplastic composition exhibits decreased emission levels of VOCs such as tetrahydrofuran (THF) compared to the neat thermoplastic resins, especially upon heating, for example during melt processing.
