Aliphatic TPU
PECOAT® Aliphatic TPU
The vast majority of TPU materials are aromatic, with a molecular structure containing a benzene ring that easily absorbs ultraviolet light and causes yellowing. Anti-yellowing TPU materials in the aliphatic isocyanate ester series, which do not contain benzene groups, ensure persistent adhesion under harsh conditions.
Product Features
Product features include good touch and elasticity, no yellowing, excellent transparency, anti-extraction, low crystallization point, anti-mold, water resistance, and excellent weather resistance.
Use
This product is widely used in watch straps, electronic accessories, clothing accessories, automotive interiors, automotive protective films, lighting strips, outdoor products, and high-demand special environment products.
