Abs : a terpolymer produced from 3 monomers, acrylonitrile, butadiene and styrene. Acrylonitrile and styrene supply chemical resistance, butadiene adds effect resistance and would make the plastic suited for home furniture, pc housings and so forth.
Acrylic: a tricky thermoplastic produced from acrylic acid or a by-product of acrylic acid. Best regarded as a glass substitute, generally below the trade names Perspex, Lucite and Plexiglas.
Amino plastics: Plastics produced from ammonia primarily based compounds, particularly urea formaldehyde and melamine formaldehyde.
Bakelite : definitely a trade identify but regularly employed as a generic identify for phenol formaldehyde (phenolic).
Cellophane : A Du Pont trade identify for movie produced from regenerated wood pulp (cellulose).
Cellulose : The fibrous subject in all plant cells, with a extensive chain molecular structure. The most typical sources employed for generating plastics are cotton fibres and wood pulp
Cellulose acetate: A difficult thermplastic produced from cellulose in the type of cotton linters, dealt with with acetic acid and acetic anhydride. Used for lots of domestic mouldings this kind of as spectacle frames, toothbrush handles, and as transparent packaging movie.
Cellulose acetate butyrate: A thermoplastic produced from cellulose dealt with with acetic and butyric acids. Clear, opaque or coloured, with excellent moulding characteristics, employed the place additional moisture resistance and dimensional security than cellulose acetate is expected.
Copolymer: A plastic produced by polymerizing two monomers, eg styrene and acrylonitrile .
Elastomer: A artificial plastic with the versatile houses of rubber.
Epoxy resin: A incredibly difficult thermosetting resin employed as a coating, or strengthened to make mouldings or laminates.
Ester : A compound made by the reaction amongst an acid and an liquor.
GRP : Glass strengthened polyester, ie polyester resin strengthened by glass fibres, generating the resin, which has no energy of its own, into a incredibly tensile substance. Commonly employed to develop boats, home furniture and vehicles.
HIPS : Higher effect polystyrene
LLDPE : Linear reduced density polyethylene, a new style of reduced density polythene.
Melalmine : Melamine formaldehyde, a thermoset made by reacting (triaminotriazine) with formaldehyde. A difficult glossy plastic typically strengthened with a filler of wood pulp.
Monomer: A uncomplicated reduced molecular body weight compound. Polymerization backlinks monomers together to type significant molecular body weight polymers.
Nylon: Not one particular substance but a group of incredibly difficult and versatile components named polyamides. Thermoplastic and typically observed as fibres or employed reliable, as gears, zips and additional recently as dyed jewellery.
Phenolic: abbreviated edition of phenol – formaldehyde. Phenolic is typically strengthened with a filler, but forged phenolic has no filler and can be translucent. It can be effortlessly coloured and is employed decoratively for jewellery, radio cupboards and all sorts of ornaments.
Polycarbonate : A incredibly difficult thermoplastic, typically observed as a substitute for glass, eg: vandal evidence phone kiosks,bullet evidence shields, baby bottles and picnicware.
Polyesters : Complex ester compounds which are thermosetting and can be polymerized at place temperature, eg GRP.
Polymer : A further phrase for a plastic substance: one particular which has been produced from chains of molecules of one particular or additional monomers. Polymers (plastics) are organic and natural substances, produced from hundreds or thousands of molecules joined together in a repeating chain pattern (also regarded as macromolecules).
Polymerization : The chemical system of linking monomers to type new compounds named polymers. For case in point,ethylene is polymerized into polyethylene, (polythene for limited).
Polypropylene : A thermoplastic polymerized from propene, incredibly close to polythene in molecular structure, but more challenging, much better and a lot less versatile.
Polystyrene : A brittle.drinking water white thermoplastic polymerized from styrene – (phenylethylene). The brittleness is defeat by incorporating some butadiene, which benefits in toughened polystyrene also regarded as significant effect polystyrene (HIPS), a copolymer of butadiene and styrene. Expanded polystyrene is the rigid white foam employed for packaging.
