Vandar^®

Product Finder

Vandar^® thermoplastic polyester alloys (PBT) combine seeming contradictions — high ductility and good stiffness with excellent chemical and thermal resistance for hard-to-beat properties.

All unreinforced Vandar^®polyester products have high impact resistance while retaining strength and stiffness. One grade has a V-0 rating in the UL 94 flammability test down to a thickness of 0.85 mm (0.033 in). A key to the value offered by these Vandar^® products is that they have high impact well below freezing, yet retain sufficient stiffness to prevent creeping and sagging at much higher temperatures.

Product Properties:

High impact and notched impact strength at low temperatures
High heat-deflection temperature, particularly the glass fiber-reinforced grades (service temperature to 120°C)
High resistance to organic solvents, fuels, lubricants and brake fluids
High abrasion resistance
Good processability
Paintability

These alloys are easy to mold and retain their impact strength down to -30°C; they are available in both unreinforced grades and as compounds with glass fiber and minerals. Glass-reinforced Vandar^® PBT alloy grades provide added strength, stiffness and toughness over a wide temperature range, from -40°C to 130°C.
