What are the functional differences between plastic and rubber?

Answer:

Plastic materials (LC plastic raw materials wholesale, high temperature resistant plastic material, PPS, LCP, PET, PA, PES plastic raw materials suppliers): the main ingredient is resin, is made of polymer resin as main ingredients into a variety of auxiliary material or adding agent, at a certain temperature, with plastic and motor can be under pressure molded into shape and maintain the same shape of material under certain conditions;
Plastic has good insulation for electricity, heat and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption, noise elimination, and outstanding performance.
Plastic raw materials are extracted from some oil in the most familiar part of PC material (polycarbonate) is extracted from the oil, the PC material has a gasoline burning time; ABS (acrylonitrile butadiene styrene plastic) is made from coal, ABS a soot like when burn out; POM (polyoxymethylene plastic) is made from natural gas, POM will have a very smelly smell of gas in the burn time.
General characteristics of plastic raw materials (LC plastic raw materials wholesale, high temperature resistant plastic materials, PPS, LCP, PET, PA, PES plastic raw material suppliers):1) the plastic material is heated and compressed, and the coefficient of linear expansion is much larger than that of metal;2) the stiffness of a general plastic material is one order lower than that of the metal;3) the mechanical properties of plastic raw materials will decrease obviously when heated for a long time;4) the general plastic material is temporarily subjected to stress at normal temperature and below its yield strength, and permanent deformation occurs;5) plastic raw materials wholesale, sensitive to notch damage;6) the mechanical properties of plastic raw materials are usually much lower than those of metals, but some composite materials have higher specific strength and specific modulus than metals. If the products are properly designed, they will be more effective;7) the mechanical properties of reinforced plastic raw materials are various;8) some plastic materials absorb moisture and cause changes in size and properties;9) some plastics are flammable.
