- Polybutylene terephthalate (PBT) is a synthetic semi-crystalline engineered thermoplastic with similar properties and composition to polyethylene terephthalate (PET). It is part of the polyester group of resins and shares similar characteristics to other thermoplastic polyesters. Additionally, it is a high-performance material with high molecular weight and is often characterized as being a strong, stiff, and engineerable plastic. Color variations of PBT range from white to bright colors.
Preferred Fields:
Valves, filler pistons, bearings and bushings, gears and wear pads, packaging machinery parts, food processing machinery components, wheels and rollers, electrical components.
Characteristics:
- Excellent stain resistant
- Excellent machining characteristics
- High strength, toughness
- Excellent stiffness-to-weight ratio
- Resistance to environmental changes
