PET Polyester
Versatile & Ideal for Coatings
History
PET is the most common thermoplastic polymer in the polyester family. The first US commercial polyester fiber production was completed in 1953 by DuPont™ under the name Dacron®. It is the same polymer resin utilized in the plastic bottle industry.
Composition
PET is produced in a melt-spun and drawing process. The three processes utilized in the production of PET fiber are polymerization, melt-spinning, and drawing or hot stretching the fibers based upon their elongation requirements.
Common Types & Deniers
High Tenacity
Standard Shrink
Low Shrink
Ultra-low shrink
Deniers: 50 - 3000
IMPACT
- Good chemical resistance
- Hydrophobic
- Good abrasion resistance
- Good tensile strength
