Difference between modified plastics and non modified plastics

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".

Guangdong Wish supply PC / ABS cp8320 electronic shell plastic raw materials

Guangdong Wish Industrial Co., Ltd., established in 1999, is a well-known professional high-tech material supplier in China, aiming to provide excellent material application solutions for outstanding Chinese manufacturers and provide high-quality technical services for the realization of these solutions. At present, the company's main brands are saber basic innovative plastics, corstar (Bayer), DuPont, etc., and the best-selling materials are PC, PC / ABS, PA66, etc. PC / ABS, polycarbonate and acrylonitrile butadiene styrene copolymer and mixture are thermoplastic plastics made of polycarbonate and polypropylene fine (ABS) alloy. They combine the excellent characteristics of the two materials, the formability of ABS materials and the mechanical properties, impact strength, temperature resistance and UV resistance of PC, which can be widely used in automobile interior parts, automobile interior parts and so on Business machines, communication equipment, household appliances and lighting equipment. Guangdong Weixin Industrial Co., Ltd. long term supply of PC / ABS models PC / ABS cp8320 electronic case Product performance: PC / ABS is a kind of modified engineering plastics synthesized by mixing. PC is polycarbonate and ABS is a copolymer of acrylonitrile (a), butadiene (b) and styrene (s). The properties of the modified plastics are better than those of pure PC and ABS, such as the improvement of impact resistance, heat resistance, hardness and so on. ABS plastic Features: 1. Good comprehensive properties, high impact strength, chemical stability, good electrical properties 2. It has good fusibility with 372 PMMA and can be made into two-color plastic parts 3. There are high impact, high heat resistance, flame retardant, reinforced, transparent and other grades.   4. The fluidity is a little worse than hips, better than PMMA, PC and so on.     In the process of granulation, when the thrust is insufficient, the temperature can only be increased to make the molten plastic closer to the liquid state. Although the requirement of insufficient thrust is solved, the price and quality of the finished product after granulation are reduced by an even n grade at the cost of increasing the plastic plasticity. Of course, for the recycling and granulation of PBT waste, the RB series model can be used with the matching Rx The sub machine is combined into a granulator. Application: Typical applications: mobile phone case, computer and commercial machine shell, electrical equipment, lawn gardening machine, automobile parts dashboard, interior decoration and wheel cover. synthetic method There are many ways of producing ABS resin. Now the industrial equipment is mainly applied to emulsion grafting technology and continuous bulk polymerization. Typical application range:

Special PC C6555 for mobile phone case

After more than ten years of development, Weixin has not only won a broad market, but also has a number of long-term, stable and well-known partners with its professional industry vision and insight. At present, the company's main brands are saber basic innovative plastics, cortex (Bayer), DuPont, etc., and its best-selling materials are PC, PC / ABS, PA66, etc. PC is the abbreviation of polycarbonate, polycarbonate in English is polycarbonate, referred to as PC engineering plastics. PC material is actually one of the engineering plastics we call. As a widely used material in the world, PC has its own characteristics, advantages and disadvantages. PC is a kind of amorphous thermoplastic resin with excellent comprehensive performance, which has excellent electrical insulation, extensibility and size In addition, it has the advantages of self extinguishing, flame retardant, non-toxic and colorable. It can be seen in every corner of your life. Its large-scale industrial production and easy processing also make its price extremely low.   Wish company has a large number of PC plastic raw materials for mobile phone case Advantages: good transparency, strong hardness, falling resistance, light, good strength and toughness Disadvantages: not resistant to scraping, strong acid, alkali and ultraviolet   PC protective case is different from silica gel and TPU case.
