PPT, or Polytrimethylene Terephthalate, is a polyester polymer derived from 1,3-propanediol (PDO) and terephthalic acid. It is known for its superior elasticity, resilience, dyeability, and soft feel, making it a preferred choice in both technical plastics and fiber-grade applications.
It combines the dimensional stability of PBT with the softness of nylon and is often used in:
Textile fibers
Automotive interiors
Engineering plastics
High-performance films
High elastic recovery and resilience
Excellent stain resistance and dyeability
Low moisture absorption
Good dimensional stability
High mechanical strength and flexibility
Soft hand-feel (ideal for apparel and upholstery)
| Form / Grade | Applications |
|---|---|
| PPT Granules (Fiber Grade) | Textile fibers, carpets, activewear |
| PPT Resin (Engineering Grade) | Injection molded parts, auto interiors |
| PPT Compounds | Electrical, furniture, appliance components |
| Recycled PPT | Fiber blends, upholstery, low-cost items |
