- Polyurethanes: insulating foams, mattresses, coatings, adhesives, car parts, print rollers, shoe soles, flooring, synthetic fibers, etc. Polyurethane polymers are formed by combining two bi- or higher functional monomers/oligomers.
- Polyurea/polyurethane hybrids used for abrasion resistant waterproofing coatings.
- Vulcanized rubber.
- Bakelite, a phenol-formaldehyde resin used in electrical insulators and plasticware.
- Duroplast, light but strong material, similar to Bakelite used for making car parts.
- Urea-formaldehyde foam used in plywood, particleboard and medium-density fiberboard.
- Melamine resin used on worktop surfaces.[1]
- Diallyl-phthalate (DAP) used in high temperature and mil-spec electrical connectors and other components. Usually glass filled.
- Epoxy resin [2] used as the matrix component in many fiber reinforced plastics such as glass-reinforced plastic and graphite-reinforced plastic; casting; electronics encapsulation; construction; protective coatings; adhesives; sealing and joining.
- Epoxy novolac resins used for printed circuit boards, electrical encapsulation, adhesives and coatings for metal.
- Benzoxazines, used alone or hybridised with epoxy and phenolic resins, for structural prepregs, liquid molding and film adhesives for composite construction, bonding and repair.
- Polyimides and Bismaleimides used in printed circuit boards and in body parts of modern aircraft, aerospace composite structures, as a coating material and for glass reinforced pipes.
- Cyanate esters or polycyanurates for electronics applications with need for dielectric properties and high glass temperature requirements in aerospace structural composite components.
- Mold or mold runners (the black plastic part in integrated circuits or semiconductors).
- Furan resins used in the manufacture of sustainable biocomposite construction,[3] cements, adhesives, coatings and casting/foundry resins.
- Silicone resins used for thermoset polymer matrix composites and as ceramic matrix composite precursors.
- Thiolyte, an electrical insulating thermoset phenolic laminate material.
- Vinyl ester resins used for wet lay-up laminating, molding and fast setting industrial protection and repair materials.
