What are the raw materials made of modified plastics?
Broadly speaking, the modification is to change the original performance, such as TPU, flame retardant, anti UV and so on; a narrow sense, the industry will be the new material of TPU polymerization, production is not called modified, and those who buy TPU new material made of flame retardant TPU, called "back modified". The modification process involves adding some resins or additives.
In order to reduce costs, improve performance and meet different needs, plastics are often modified to suit a variety of practical requirements. Commonly used methods are mainly:1. filling modification, adding a certain amount of filler in plastic is an important way to reduce plastic prices and improve performance. Such as phenolic resin filled with wood and paper made of bakelite practical material, overcomes the weakness of crisp.2. blends of two or more polymers with similar properties and two or more polymers are blended in a certain proportion to make polymer blends.3. copolymerization of two or more than two kinds of monomer polymerization of a copolymer of ethylene propylene rubber, such as copolymerization of ethylene and propylene has a good elasticity; acrylonitrile, butadiene and styrene copolymer obtained with ABS resin.
Plastic modification is to petrochemical production out of large quantities of general resin through physical, chemical, mechanical, improve or increase their capabilities to special environmental conditions in electricity and magnetism, light, heat, aging resistance, flame retardancy, mechanical properties and other aspects of the use function. Modified plastics is a plastic industry involving a wide range of areas, high technology content, and the modification technology of plastics - filling, blending and modification is raw materials and processing plastic products into almost all of the. From the production of raw material resin to the modification of plastic masterbatch from various specifications and varieties, in order to reduce the cost of plastic products and improve their functionality, the plastic modification technology can not be separated
