PBT (Polybuthylenetereftalate) is a high performances techno-polymer and an extremely versatile product.
Thanks to its high heat resistance and its mechanical properties, PBT bristles is widely used in the brush industry.
The PBT bristles have an excellent bend recovery, a very good resistance to abrasion and to sun exposure.
PBT filaments are suitable for food contact and are therefore available in food-grade colors.
PBT filaments are non-hygroscopic, so their properties are not changing significantly between wet and dry applications.
