PBT
- Alternative Designations: Polybutylene terephthalate / Arnite
Description:
PBT is a semicrystalline polymer with excellent physical, chemical and electrical properties. It has a high melting point and good dimensional stability. PBT is also resistant to heat, UV light and chemicals.This material has excellent resistance to abrasion and creep. It has a low coefficient of friction and a low moisture absorption. PBT is chemically resistant to strong and weak acids. It is used in gears, bushings and bearings.

Injection moulding VDI surface finishesInjection moulding VDI surface finishes
VDI
VDI is an international standard for mould texturing of matte surfaces. It is mainly processed by Electrical Discharge Machining (EDM) when mould machining.
Notes:VDI12, VDI15, VDI18,VDI21, VDI 24, VDI27, VDI30, VDI33, VDI36, VDI39, VDI42, VDI45
Final result:
- Fine-to-coarse grain depending on the selection

Custom Finishing
If you select a custom finish in the Instant Quoting Engine it will require manual review. Manual quoting usually takes 1-2 business days.
Notes:Submitting for manual review with a custom request does not guarantee a quote.
