They have improved resistance to high temperatures [1] [2] and chemicals and even withstand environments where Oxygen-Plasma are present for many hours. Certain grades have a maximum continuous service temperature of 327 °C (621 °F).
There are many synonyms for the term high-performance plastics, such as: high temperature plastics, high-performance polymers, high performance thermoplastics or high-tech plastics. The name high temperature plastics is in use due to their continuous service temperature (CST), which is always higher than 150 °C by definition (although this is ...
These properties are influenced by a 400-450 °F (204-232 °C) continuous use temperature and a glass transition of 500 °F (260 °C). Bismaleimide resin synthetic pathway and structure This thermoset polymer type is merged into composites as a prepreg matrix used in electrical printed circuit boards , and for large scale structural aircraft ...
Polyphenylene sulfide is an engineering plastic, commonly used today as a high-performance thermoplastic. [3] PPS can be molded, extruded, or machined to tight tolerances. In its pure solid form, it may be opaque white to light tan in color. Maximum service temperature is 218 °C (424 °F).
Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. The sheet, or "film" when referring to thinner gauges and certain material types, is heated in an oven to a high-enough temperature that permits it to be ...
Animation of heat-shrink tubing, before and after shrinking. Heat-shrink tubing (or, commonly, heat shrink or heatshrink) is a shrinkable plastic tube used to insulate wires, providing abrasion resistance and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical wiring.
Excellent resistance to solvents and chemicals. Low application temperature, suitable for heat-sensitive substrates. Heat-resistant after curing, with service temperatures generally from −30 °C (−22 °F) to 150 °C (302 °F). Ink-solvent resistant. Often used in bookbinding, automotive, aerospace, filter and plastic bag applications.
The effects are discoloration, embrittlement and eventual cracking. Elevated temperatures and oxygen tend to accelerate the deterioration. Tanks listed as suitable for outdoor service are protected from UV attack by: coloring or pigmenting and/or adding internal stabilizers which preferentially absorb or dissipate the UV energy.
