Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. Depending on the chemical structure, polyester can be a thermoplastic or thermoset. There are also polyester resins cured by hardeners; however, the most common polyesters are thermoplastics.

Applications

  • Textile-PET
  • Resin, Bottle/A-PET
  • Special Polyester

Product Description

Unsaturated Polyester Resins (UPR) are thermoset polymers dissolved in a reactive diluent, used in combination with glass fibers or carbon fibers to make reinforced composite components. UP Resins are made up of at least two separate components; reinforced fiber and embedding matrix. Other additives may be used to improve properties or characteristics. Carbon, aramid or most commonly glass fibers may be used yielding FRP (Fiber Reinforced Plastic) or specifically GRP (Glass Reinforced Plastics) in the case of glass.

Button Grade

medium viscosity, orthophthalic based unsaturated polyester resin for button applications. It has an excellent clear color and transparency. It is suitable specifically for transparent buttons. Excellent clarity and transparency allows to colorless buttons to be made as well as clean colors.
