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.

SPI
SPI finishes are a set of standard mould finishes with different polished textures for enhanced properties.
Notes:A1, A2, A3, B1, B2, B3, C1, C2, C3, D1, D2, D3
Final result:
- Heavily polished, to semi-gloss to fine and coarse matte depending on the selection
-
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.
