The flow characteristics of ABS are non Newtonian fluids. The melt viscosity is related to the processing temperature and shear rate, but it is more sensitive to the shear rate. 2, the mechanical properties of ABS have excellent mechanical properties. The impact strength is excellent and can be used at very low temperatures. Even if ABS products are damaged, they can only be tensile failure rather than impact failure. ABS has excellent wear resistance, good dimensional stability and oil resistance. It can be used for bearings under moderate load and speed. The creep property of ABS is larger than that of PSF and PC, but smaller than that of PA and POM. The bending strength and compressive strength of ABS are inferior to those of plastics. The mechanical properties of ABS are greatly influenced by the temperature. 3, the thermal performance ABS belongs to the amorphous polymer with no obvious melting point; the melt viscosity is high, the fluidity is poor, the weatherability is poor, the ultraviolet light can change color, the thermal deformation temperature is 70 to 107 C (

因此,已開(kāi)始逐步取代天然產(chǎn)品,并進(jìn)一步發(fā)展到用于整形外科器具、石膏代替物和運(yùn)動(dòng)保護(hù)器材。近年來(lái),利用TPI優(yōu)異的結(jié)晶性和溫度的敏感性,又成功地開(kāi)發(fā)作為形狀記憶橡膠材料,倍受人們青睞。從結(jié)構(gòu)上來(lái)說(shuō),TPI是以高的反式結(jié)構(gòu)所形成的結(jié)晶性作為硬鏈段,再與其余任意形呈彈性相狀態(tài)部分的軟鏈段結(jié)合而構(gòu)成的熱塑性橡膠
Therefore, the natural products have been gradually replaced and applied to plastic surgery equipment, gypsum substitute and sports protection equipment. In recent years, TPI has been successfully developed as a shape memory rubber material because of its excellent crystallinity and temperature sensitivity. Structurally, TPI is a thermoplastic elastomer formed by the crystallization of a high trans structure as a hard chain, and a soft segment that is combined with the rest of the rest of the elastic phase.
TPV主要由二部分組成,一是塑料作為連續(xù)相,二是橡膠作為分散相。通常橡膠需要與軟化油或增塑劑與之配合。硫化劑和一些輔助助劑也是必不可少的。另外為了降低成本或者提高某方面的性能,一些無(wú)機(jī)填料會(huì)被填加。[1] 中文名熱塑性硫化橡膠外文名ThermoplasticVulcanizate組成一是塑料,二是橡膠簡(jiǎn)
TPV is mainly composed of two parts, one is plastic as a continuous phase, and the other two is rubber as dispersed phase. Usually rubber should be combined with softening oil or plasticizer. Vulcanizing agents and some auxiliary auxiliaries are also essential. In addition, some inorganic fillers will be added to reduce costs or improve performance. [1] Chinese name thermoplastic vulcanizate ThermoplasticVulcanizate is made of plastic and rubber two.

Architectural building materials TPV thermoplastic vulcanized rubber (ThermoplasticVulcanizate), polyolefin thermoplastic elastomer, short for TPV, and thermoplastic vulcanized rubber (Thermoplastic Rubber) for short, called TPR, but this name is called easy and other types of thermoplastic elastomer (UK) The article is confused with Thermoplastic Elastomer, because normally thermoplastic elastomers are also called thermoplastic elastomers, especially styrene elastomers. At least in China, it seems that "TPR" has become its proprietary name. To mention TPR, it refers to the thermoplastic properties of styrene like elastomers such as SBS and SEBS. Elastomers are inseparable from the consumption of styrene elastomers in the field of civilian and end consumer goods.

PP聚丙烯是一種高剛性材料,與PE同屬聚烯烴。均聚料密度低至0.90??杉尤氩AЮw維和礦物質(zhì)(如碳酸鈣)增強(qiáng)。PP不適合0oC以下使用。如要在零下溫度使用,必須用丁二烯共聚,這樣就產(chǎn)生了共聚PP。均聚PP的的操作溫度是90oC,抗化學(xué)品(酸、堿)性能非常好。用均聚PP生產(chǎn)的零部件具有非常低的吸濕性,但注塑時(shí)收縮大。電氣性能很好,但耐紫外旋光性能、抗其它穿透性能很差。
PP polypropylene is a high rigid material and belongs to polyolefins with PE. The density of the aggregate is low to 0.90. Glass fibers and minerals (such as calcium carbonate) can be added. PP is not suitable for use below 0oC. If it is to be used at zero temperature, it must be copolymerized with butadiene, which leads to the copolymerization of PP. The operating temperature of homopolymer PP is 90oC, and its resistance to chemicals (acid and alkali) is very good. The parts produced by homopolymer PP have very low hygroscopicity, but they shrink when they are injected. Electrical properties are good, but UV resistance and anti penetration performance are very poor.
化學(xué)改性的常用方法:一種是以被改性的樹(shù)脂單體為一元,改性單體為另一元,在反應(yīng)釜內(nèi)進(jìn)行接枝共聚并獲得新的共聚物;第二種方法是將被改性樹(shù)脂作為主要原料,通過(guò)增加樹(shù)脂分子中的極性元素對(duì)其進(jìn)行有效的改性。
The common methods of chemical modification are: one is one element of the modified resin monomer, the modified monomer is another, graft copolymerization in the reaction kettle and a new copolymer. The second method is to modify the modified resin as the main raw material by increasing the polar element in the resin molecule.
