Product introduction

Application areas include

1. As the basic resin of modified materials and composites, it can be used in electrical and electronic components, automotive parts, lamp holders, capacitors, connectors, etc. after modification.

2. Used to produce PBT fiber.

PBT filament can be textured to produce elastic fibers. PBT elastic fibers are mainly used as base fabrics for swimsuits, denim fabrics, decorative fabrics, medical bandages, band-aids and plasters.

3. Basic materials used for optical cable sheathing materials.

4. Used to produce single-fiber products such as toothbrush filaments, makeup brush filaments, and wig filaments.
