About Thermosets and Thermoset Materials
Thermosets and thermoset materials are crosslinked polymers that are cured or set using heat or heat and pressure. Cured thermoset resins may soften when heated, but do not melt or flow. They generally have a higher resistance to heat than thermoplastics. Vulcanization is a thermosetting reaction that uses a crosslinked compound or catalyst. In rubber-like materials, vulcanization results in greatly increased strength, stability, and elasticity. Traditionally, sulfur is used as the vulcanizing agent for natural rubber. Thermosets and thermoset materials may contain filler materials such as powders or fibers to provide improved strength and/or stiffness. Fibers can be either chopped or wound, and commonly include glass, fiberglass, or cloth. Some products contain solid lubricant fillers such as graphite or molybdenum disulfide. Others contain aramid fibers, metal powders, or inorganic fillers with ceramics and silicates.
Many types of thermosets and thermoset materials are available. Filled or reinforced products consist of resins and modifiers such as pigments, plasticizers, or chopped fibers. By contrast, unfilled resins, base polymers, and raw materials do not contain additives. Typically, raw materials are available as pellets, powders, granules, or liquids. Stock shapes such as bars, sheets, and film are also available. Molding compounds are designed for processes such as reaction injection molding (RIM) and resin transfer molding (RTM). Composite materials consist of a matrix and a dispersed, fibrous or continuous second phase. Casting resins include a catalyst or hardener. Electrical resins and electronic-grade polymers and elastomers are used in potting or encapsulating compounds, conductive adhesives, and dielectric sealants. Specialized elastomers and rubber materials are used in optical and photonics applications and in mold and tooling fabrication. Monomers and intermediates are commonly available.
