PolyPlastics Duranex® 3400 Polybutylene Terephthalate (PBT), Standard, 40% GF filled

Subcategory: Filled/Reinforced Thermoplastic; Polybutylene Terephthalate (PBT); Polyester, TP; Polymer; Thermoplastic

Material Notes:
DURANEX® is a crystalline thermoplastic based on polybutylene terephthalate (PBT) that can be readily strengthened, modified, or otherwise performance enhanced through the addition of glass fibers or other inorganic filler additives. Therefore, as grades can be optimally designed depending on the application, various grades are provided, including flame-retardant grades, reinforced grades, and impact-resistant grades.

DURANEX®, due to its mechanical strength, heat stability, electrical resistivity and wear and abrasion-resistance, offers great potential as a well-balanced, highly reliable material, having a wide variety of applications including electronic / electro-mechanical and automobile parts and various other functional parts. Not only does it have well-balanced properties as a raw material, DURANEX® also assures moldability, dimensional stability, glossy surfaces and various fabrication capabilities providing higher added value.
