Product Description
Polybutylene terephthalate compounds
Self extinguishing by non-migrating and non-corrosive flame retardant

VESTODUR® FR3-Series are unreinforced respectively glass fiber reinforced, semi-crystalline thermoplastic compounds for injection molding, based on polybutylene terephthalate (PBT). They have a creamy-white color.

Test bars made of these compounds are rated V-0, according UL94 by Underwriters Laboratories Inc., self-extinguishing and non-dripping.

These compounds are especially suitable for parts which are subjected to high mechanical and thermal loads and must have a very good flame-resistance.

The incorporated flame retardant is nonmigrating and does not contain polybrominated diphenyl ethers. The additive has no corrosive effects on metal inserts or neighboring metal parts. Therefore, the compounds are distinguished for moldings in the electrical and electronical industry. Laser marking with high contrasts is possible.
