PBT (Engineering Polymer)
Polybutylene Terephthalate (PBT) is a semi-crystalline engineering thermoplastic material. It has similar properties and composition to polyethylene terephthalate (PET).
PBT is a member of the polyester family of polymers.The PBT product range includes a wide variety of grades which are great for injection molding. These include Reinforced, Filled, Impact-modified and Flame-retardant
The physical and chemical characteristics of polybutylene terephthalate include the following:
Heat resistant, Having excellent dimensional stability and processability, Easy molding, High mechanical strength, High crystallization, High molecular weight, Low water absorption speed, High mechanical strength, High resistance to chemicals and solvents, Melting point 223°C, Low abrasion and creep resistance (excellent alternative to metal parts), Having low surface friction, UV protection when outdoors.
Due to its mechanical and electrical resistance, excellent toughness and resistance to cracking due to fuels and lubricants, PBT is ideal in applications like automotive/transportation, household/consumer goods and items and ... .
