What is CORTERRA PTT?
CORTERRA PTT is the Shell trademark name for the aromatic polyesters known as polytrimethylene terephthalate (PTT). CORTERRA PTT polymers are produced by the polycondensation reaction of purified terephthalic acid (PTA) and 1,3-propanediol (PDO). PTT competes with the other aromatic polyesters - polyethylene terephthalate (PET) and polybutylene terephthalate (PBT) - as well as with nylon.
How is CORTERRA PTT used?
CORTERRA PT is used in:
- Fibres for carpet and textiles
- Non-woven fabrics
- Other emerging applications, including monofilament, film and engineering thermoplastics (ETPs).
