Polyurethanes resin embodies the properties of foam, rubber, thermoplastic plastics as well as thermoset plastics, it can be used as elastomers, adhesives and coating etc and can also be adopted as synthetic fiber of large shrinkage. The substance is of high elasticity, obdurability and tensile strength, and can fight against the erosion from oil or [...]
The cellulose plastic is provided with high transparency and pliability as well as sound processability, fluidity and molding ability. The plastic has bright surface and sound dimension precision. It can be manufactured into fire resistance spectacles frame, tools, electric parts and transparent packing cases.
PC is a kind of colorless or primrose material, with high tensile strength, bending intensity, elasticity and impact resistance. These physical properties, almost equal to metallic materials, will not change dramatically with different temperature and the intensity can be retained under 140 celsius degree. […]
POM is a tough and strong material with sound heat resistance and solvent resistance. The property of POM is similar to nylon and PC, which is pretty strong and requires high thermal deformation temperature. In addition, […]
Nylons are generally tough and strong and boast high oil resistance and chemical resistance. They can be in stable use whether under high temperature or low temperature and hence possess excellent qualification for being used as engineering plastic. […]
Flurocarbon resin is a kind of engineering plastic with excellent performance. Its chemical resistance and electric insulation is the best among plastics and its property will not change whether under high temperature or low temperature, the price, however is a bit too high. […]
The commonest plastic that can be found in daily life is polyethylene ( PE ) which is polymerized from ethylene industrially fractionated petroleum. […]
Polypropylene is closely connected with polyethylene with respect to raw materials, manufacturing technique as well as properties. The raw materials, i.e. propylene and ethylene, are both contained in a large amount in the decomposing gas of petroleum. […]
Acetone works together with prussic acid to form cyaniding propyl alcohol which is dehydrated with oil of vitriol, the substance is further combined into methacrylates through reaction with alcohol ester, and finally through polymerization with catalyzer, PMMA is thereby got. […]
The aggregation of stryrene monomer,acrylonitrile monomer and butadiene rubber can produce a polymer (ABS) constituted by acrylonitrile ( A ), butadiene rubber ( B ) and styrene ( S ) in various proportions. The characteristic thereof, due to the ingenious combination by the three components, shows such features as high impact resistance, large tensile strength [...]
