PBT (Polybutylene Terephthalate) Compound

PBT exhibits high rigidity, strength, good dimensional stability, low moisture absorption and high chemical resistance, but also a very high resistance, has a unique processing properties and surface appearance. Used in the production of various types of high performance products for industrial purpose.

Modification of PBT by compounding with glass fiber, flame retardant, mineral fillers and modifiers produces a substantial change in the properties of the base material and gives to compositions based on PBT the following properties:

Excellent stiffness and hardness, good mechanical strength, good creep and fatigue resistance, very good thermal stability, high wear resistance and the low friction, good dimensional stability, very good surface finish, no tendency to form stress cracks, high tracing resistance, high good sliding properties, excellent heat ageing behavior. Flame retardant compound with halogen and halogen free, UL94 V-2 or V-0 classifications (UL approved grades), glow wire flammability index, glow wire ignition behavior (no flame), low smoke density.

Fillers/reinforcements/modifiers

Glass fibers, glass beads, carbon fibers, mineral fillers are available with varying contents in different combinations and also filled materials containing PTFE available with appropriately low friction and improved wear. Heat stabilizers- hydrolysis stabilizers- lubricants- UV stabilizers, electrical conductive etc. are being used in non-reinforced and reinforced grades to increase specific material properties.

Applications:Due to excellent balance of properties, PBT grades are suitable for an extensive range of industries like automotive, transportation, electric/ electronic, furniture, construction, home appliances, sports and leisure, garden and power tools, safety equipments and medical.
