Plastics 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.
Semi finished shapes and stock materials include sheets, plates, rods, bar stock, tubes, profiles, etc. in plastic, metal, ceramic and other materials.
Thermoplastics and thermoplastic materials soften when heated and harden when cooled. They can withstand many heating and cooling cycles and are often suitable for recycling.
Thermosets and thermoset materials are crosslinked polymeric resins that are cured or set using heat or heat and pressure. They generally have a higher resistance to heat than thermoplastics.
