Description

Reinforced Polybutylene terephthalate with 30% glass fiber.

Very good stiffness and toughness

Wear resistance

Excellent surface finishes and good colourability.

It has an excellent electrical insulation characteristics and high arc-resistant grades are available.

Many flame retardant grades have UL recognition (class V-0).

It typically has high chemical and heat ageing resistance.

The good melt stability normally enables the recycling of properly handled production waste.
