New Engineering Thermoplastic Resins Based on Polybutylene Terephthalate

Gafite ^® LW molding compounds are impact modified, mica/glass reinforced PBT's (polybutylene terephthalate). They will meet a variety of design and molding criteria for such components as side and rear panels, louvres, deck lids and fender extensions, and are also of interest in other industries where low warpage characteristics are desired.

The Gafite ^® LW polyester compounds essentially eliminate out of mold warpage while offering greater mechanical strength, resistance to environmental aging, resistance to high humidity, resistance to automotive fluids and lower sensitivity to regrind at comparable warpage than the conventional mineral filled nylon systems currently used for exterior automotive parts.

Key advantages of Gafite ^® LW compounds over conventional PBT and mineral filled nylons will be discussed in depth.
