PET (Polyethylene Terephthalate)
Description

PET, often called just polyester, is the most commonly available plastic in the world. It is highly flexible, colorless, and semi-crystalline resin in its natural state. Polyester resins are known for their excellent combination of properties such as hardness, stiffness, dimension stability, thermal, chemical resistance and it absorbs little water.

Features
  • Chemical Resistance:Excellent resistance to alcohols, aliphatic hydrocarbons, oils, greases, and diluted acids.
  • Strength to Weight Ratio:Extraordinarily strong for its lightweight.
  • Shatterproof:Not break or fracture, making it a great substitute for glass in some applications.
  • Wild Range of Use Temperature:-60℃ ~ 130℃
  • Transmissivity:It is naturally transparent. If high transmissivity is needed than plastics like Acrylic or PC, it may be a better choice.
  • Good Gas and Moisture Barrier
Applications

plastic bottles, tapes, trays, microwavable containers, cosmetic jars, E&E industry, fabrics, wiper arms, headlamp retainer, gear housings, engine cover, connector housings, waterproofing barrier, 3D printing filament…
