Until now, the market has primarily used carbon-fiber-reinforced thermosetting plastics for example in bodywork parts for automobiles.
Polymers fall into two distinct groups, thermosetting plastics and thermoplastics.
Thermosetting plastics include phenolic, epoxy, alkyd polyester, polyurethane, urea-formaldehyde and unsaturated polyester resins.
Q-Cel hollow microspheres are fine, inorganic spherical particles developed as low-density fillers/extenders for thermosetting plastics.
When applied to a clean, warm mold, RR-280 WB will give a thin, highly durable, heat stable release film capable of releasing a wide cross-section of elastomers and thermosetting plastics, according to the manufacturer.

Key advantages of thermosetting plastics include high dimensional stability; low shrinkage: excellent resistance to corrosion, creep, and heat; and design flexibility.
Benefits are said to include multiple releases between applications, reduced scrap rate, low buildup and easy release for most elastomers and thermosetting plastics such as urethanes and phenolics.
