About Polymers and Plastic Materials

Polymers and plastic materials are organic, synthetic or processed polymers that are supplied as raw materials or stock shapes. They typically consist of thermoplastic or thermosetting resins and can be made into many forms. Stock shape forms include sheets, plates, rods, tubes, films, or extruded profiles. Often, thermoplastic resins are supplied as pellets for feeding into molding machines or extrusion presses. Thermosets may be supplied as two-part liquid resins such as epoxies, or as a non-flowing mass premixed with fiber reinforcement. Polyester bulk molding compounds (BMC) are an example of this latter form. Water-based resins, water-born resins and latex products are plastics and plastic materials that consist of resin or polymer droplets that are dispersed and suspended in a water carrier or solvent.

There are many material types and grades for polymers and plastic materials. Cure type or cure technology is also an important consideration. Material types include monomers and intermediates, binders and base polymers, composite materials, thermoplastic materials, thermosets and crosslinked materials, semi-finished shapes, fabricated shapes, and resins and compounded raw materials such as pellets and liquids. Electrical and electronic materials, optical grade materials, and self-lubricated or bearing-grade plastics and plastic materials are also available. With regard to cure type or cure technology, choices include air setting or film drying, anaerobic, thermoplastic or hot melt, thermosetting or cross-linking, room-temperature curing or vulcanizing, and pressure sensitive adhesive (PSA). Polymers and plastic materials that are cured with ultraviolet light (UV) are also available, as are reactive resins, single-component products, and two-component systems.
