PET (Polyethylene Terephthalate)

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.

  • 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
