Valox* Resin
Valox* Resin All Series
The Valox* family of thermoplastic polyester resins are semi-crystalline materials based on polybutylene terephthalate (PBT) and/or polyethylene terephthalate (PET) polymers. Valox resins are highly tailorable, combining heat, chemical resistance, and outstanding electrical properties with exceptionally good processability and surface appearance.

Valox* Resin PBT+PC 508R 数据表
30%GR PBT+PC. Excellent mechanical and thermal performance. Non-FR. Reduced warpage characteristics. Applications same as VALOX 420R.

1、Typical values only. Variations within normal tolerances are possible for various colors. All values are measured after at least 48 hours storage at 23℃/50% relative humidity. All properties, except the melt volume and melt flow rates, are measured on injection molded samples. All samples tested under ISO test standards are prepared according to ISO 294.
2、Only typical data for selection purposes. Not to be used for part or tool design.
3、This rating is not intended to reflect hazards presented by this or any other material under actual fire conditions.
4、Internal measurements according to UL standards.
5、Measurements made from laboratory test coupon. Actual shrinkage may vary outside of range due to differences in processing conditions, equipment, part geometry and tool design. It is recommended that mold shrinkage studies be performed with surrogate or legacy tooling prior to cutting tools for new molded article.
