VESTODUR® X7212 Evonik Degussa Polybutylene Terephthalate (Glass Fiber Reinforcement, 45%)

Product Description

Self-extinguishing, reinforced polybutylene terephthalate compound with nonmigrating and non-corrosive flame retardant

VESTODUR X7212 is a glass fiber reinforced (45%), semi-crystalline thermoplastic com pound for injection molding, based on polybutylene terephthalate (PBT). The selfextinguishing compound has a creamy-white colour.

VESTODUR X7212 is used for parts of high mechanical and thermal resistance.

Test bars made of the compound are rated V-0 self-extinguishing according to UL94 by Underwriters Laboratories Inc.

The incorporated flame retardant is nonmigrating. The additive has no corrosive effects on metal inserts or neighboring metal parts. Therefore, the compound is distinguished for moldings in the electrical and electronical industry. Laser marking with high contrasts is possible.
