Acrylonitrile is used principally as a monomer to prepare polyacrylonitrile, a homopolymer, or several important copolymers, such as styrene-acrylonitrile (SAN), acrylonitrile butadiene styrene (ABS), acrylonitrile styrene acrylate (ASA), and other synthetic rubbers such as acrylonitrile butadiene (NBR).
EPDM rubber (ethylene propylene diene monomer rubber), a type of synthetic rubber, is an elastomer characterized by a wide range of applications. This is an M-Class rubber where the 'M' in M-Class refers to its classification in ASTM standard D-1418; the M class includes rubbers having a saturated chain of the polyethylene type.
Behind PVC, particulate fillers are used in the second largest quantity in polypropylene (PP). Table 1 gives an estimate of the amount of fillers used in Western Europe and about the increase of their consumption. Three fillers are applied in considerable quantities: talc, CaCO 3, glass fibers (GF).
Compared to the native polymer, glass-filled materials have improved mechanical properties of rigidity, strength and may also have improved surface hardness. Compared to sheet materials. Bulk glass filled materials are considered distinct from fibreglass or fibre-reinforced plastic materials.
Polypropylene (PP) is a thermoplastic “addition polymer” used for consumer products, ropes, automotive parts, and special devices like living hinges. Polypropylene (PP) is a thermoplastic “addition polymer” used for consumer products, ropes, automotive parts, and special devices like living hinges.
Polypropylene carbonate is soluble in polar solvents like lower ketones, ethyl acetate, dichloromethane and chlorinated hydrocarbons and insoluble in solvents like alcohols, water, and aliphatic hydrocarbons. It also forms stable emulsions in water. PPC allows the diffusion of gases like oxygen through it.
Polyvinylidene fluoride or polyvinylidene difluoride (PVDF) is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. PVDF is a specialty plastic used in applications requiring the highest purity, as well as resistance to solvents, acids and bases.
