Guangdong Wish Industry Co., Ltd.

Is it true that there are 100% non modified plastics Weixin is committed to providing excellent material application solutions for outstanding Chinese manufacturers and providing high-quality technical services for the realization of these solutions. Weixin is a regional partner of several top 500 chemical enterprises in China, such as Bayer Material Science (now costro), SABIC innovative plastics (GE), Asahi Kasei chemicals, Idemitsu Kosan and polylactics. These high-tech raw materials are mainly used in mobile phones, solar energy, led, intelligent home appliances, communication electronics, automobile / electric vehicle (EV) / high-speed rail, robot, aerospace and other fields. The modification methods of plastics can be roughly divided into the following types: 1. Reinforcement: the rigidity and strength of materials can be increased by adding fiber or sheet fillers such as glass fiber, carbon fiber and mica powder, such as glass fiber reinforced nylon used in electric tools. 2. Toughening: the purpose of improving the toughness / impact strength of plastics by adding rubber, thermoplastic elastomer and other materials, such as toughened polypropylene commonly used in automobiles, household appliances and industrial applications. 3. Blending: a method to uniformly mix two or more incompletely compatible polymer materials into a mixture of macroscopic compatibility and microscopic phase separation, so as to meet some requirements for physical and mechanical properties, optical properties, processing properties, etc. 4. Alloy: similar to blending, but with good compatibility between components, it is easy to form a homogeneous system, and some properties that cannot be achieved by a single component can be obtained, such as PC / ABS alloy or PS modified PPO. 5. Filling: to improve the physical and mechanical properties or reduce the cost by adding fillers into the plastics. 6. Other modifications: for example, conductive fillers are used to reduce the resistivity of plastics; antioxidants / light stabilizers are added to improve the weatherability of materials; Pigments / dyes are added to change the color of materials; internal / external lubricants are added to improve the processing properties of materials; nucleating agents are used to change the crystallization characteristics of semi crystalline plastics to improve their mechanical and optical properties. In addition to the above physical modification methods, there are also methods to modify plastics by chemical reactions to obtain specific properties, such as maleic anhydride grafted polyolefin, crosslinking of polyethylene, and peroxide degradation in textile industry to improve fluidity / fiber forming properties... this is not the only one. A variety of modification methods are often used in industry, such as adding rubber and other toughening agents in the process of plastic reinforcement and modification in order to reduce the impact strength; or physical mixing and chemical crosslinking exist in the production of thermoplastic vulcanizates (TPV) In fact, any kind of plastic raw material must contain at least a certain proportion of stabilizer when leaving the factory to prevent its degradation during storage, transportation and processing. Therefore, strictly speaking, "non modified plastics" does not exist. However, in industry, the base resin produced by chemical plant is usually called "non modified plastics" or "pure resin".
