1.PBT granule, which is produced by advanced PTA and BDO continual reaction,has characteristics of wide control range of intrinsic viscosity and narrow range of intrinsic viscosity deviation,low carboxyl end groups value,good color and luster
2.This product is processing fluidity, excellent thermal stability and light stability, good compatibility with resin, especially for Cable sheating. Christmas tree. This product is in full compliance with EU environmental standards (RoHS)
Advantage of PBT resin
1. Stability and mechanical properties of tensile strength and tensile modulus similar to nylon. 2. Friction coefficient of a self-lubricating. 3. Low water absorption. 4. Excellent electrical properties. 5. Good dimensional stability. 6. Chemical resistance, excellent oil resistance.
