々PA66 SC310∨Long-term supply TPV mainly consists of two parts, one is plastic as continuous phase, and two is rubber as dispersing phase. Rubber usually needs to be mixed with softened oil?or?plasticizers. Vulcanizing agents and some auxiliary additives are also essential. In addition, some inorganic fillers will be added to reduce costs?or?improve performance. [1], Chinese name thermoplastic vulcanizate, ThermoplasticVulcanizate, one plastic, two rubber Building materials? TPV thermoplastic vulcanizate (English ThermoplasticVulcanizate) polyolefin alloy, thermoplastic elastomer, referred to as TPV, thermoplastic vulcanized rubber Chinese called thermoplastic rubber (English Thermoplastic Rubber), referred to as TPR, but the name is easy and other types of thermoplastic elastomer the body (English Thermoplastic Elastomer) confused together, because usually thermoplastic elastomer is also known as thermoplastic rubber, especially Styrene Elastomer, at least in Chinese seems to be "TPR" has become the exclusive name, mention TPR, refers to SBS, SEBS Styrene Elastomer as the base material of thermoplastic elastomer, and the Styrene Elastomer in the civil field and terminal consumer goods consumption is inseparable. TPV 101-80, TPV 121-87, TPV 121-80, TPV 111-35, TPV 111-87, TPV 111-45, TPV 111-80, and TPV 8271-75 PP polypropylene is a kind of high rigid material and belongs to polyolefin with PE. The homopolymer density is as low as 0.90. Glass fiber and minerals (such as calcium carbonate) can be added. PP is not suitable for use below 0oC. If it is to be used at subzero temperatures, butadiene must be copolymerized, thus resulting in copolymerization of PP. The operating temperature of homopolymerization PP is 90oC, and the chemical (acid and base) properties are very good. Parts produced with homopolymer PP have very low moisture absorption, but they shrink considerably during injection. The electrical properties are good, but they are resistant to ultraviolet light and have poor penetration resistance. Chemical modification of the commonly used method which is a kind of modified resin monomer is one yuan, modified monomer for another element, graft copolymerization in the reactor and obtain new copolymer; the second method is to be modified resin as the main raw material, through the modification of its effective to increase the polarity of the resin molecular elements. LDPE characteristics: low-density polyethylene is colorless and translucent particles, molecules have long branched chain, molecular arrangement is not close, low temperature toughness is very high. Processing and application of polyethylene The processing of polyethylene blow molding, extrusion, injection molding available methods, widely used in the manufacture of thin film, hollow fiber and other products, daily-use sundry goods. (1) polyethylene applied film More than half of the total yield of low density polyethylene blow molding film, this film has good transparency and tensile strength, widely used as packaging materials of various food, clothing, medicine, chemical fertilizer, industrial and agricultural films. It can also be extruded into composite films for packing heavy objects. Since 1975, HDPE films have been developed with high strength, low temperature resistance, moisture resistance and good printability and processability. Zui is also made into thin films. Its strength and toughness are better than those of LDPE, and its puncture resistance and rigidity are better. The transparency is poor, but it is still slightly better than hdpe. In addition, the coated polyethylene coating can be extruded on paper, aluminum foil?or?other plastic film to make polymer composite material.
