東莞市千泰塑膠原料有限公司為您提供app//40gr61hb/抗張。app//40gr61hb/抗張
app//40gr61hb/抗張eva as the product of disposable medical instruments mostly use medical grade pvc (pvc)/polycarbonate (pc),&pvc in the process of thermal deco-ition has strong corrosion of pc steel, high hardness, high viscosity,&therefore must be polished performance of corrosion resistance, wear&high on plastic part parts material requirements. most medical injection machines adopt the hard chromium plating method of the machine barrel screw/the stainless steel as the material to make the machine - screw to meet the spe-l requirements. in addition, in order to prevent gas in the process of thermal deco-ition of pvc, requirements for fixed template surface aluminizing treatment, but also for foreign gold/aluminum panels made of stainless steel sheet metal, sheet metal joint using non-toxic silicone seal to prevent gas generated in the manufacturing process of plastic ran outside (gas generated in the process of plastic processing can be collected through spe-l equipment after purification treatment can be discharged into the atmosphere).
pvc is the main source of dioxin. dioxin (tcdd), two oxygen (miscellaneous) the most deadly dioxin in the family is a kind of substance, as everyone knows the carcinogens&catabolic hormones&a toxic compound, has a great harm to human&animal. when pvc production, recycling&scrap in the incinerator,/pvc products in the combustion accident such as garbage landfill, will produce dioxin.
eea
application area
1, eea is flexible, flexible, flexible hose, low temperature seal ring, communication cable semi conductive casing, surgical bags, surgical gloves, packaging films&containers.
2, eea can be used as a modifier for high temperature resistant extrusion coating (good adhesion to matrix material)&other plastics at low temperature resistance&environmental stress cracking.
3, eea can be used as carbon black to make conductive material.
4, eea injection molding of automobile steering wheel&other parts, motor parts, safety equipment, cold storage tray, household goods, sports shoes etc..
5, eea can be hollow in all kinds of oil&drug containers.
6, eea can be coated&laminated products can be used as a variety of packaging materials, metal coatings.
7, eea can be used as electrical insulation material, shrinkable packaging film, shrinkable pipe, co-ite film&foam plastic.
eea is more used in food packaging than eva, poe, eaa&other polyolefin resins,&the content of ea can not exceed 8% of fda.
lcp plastic raw materials are excellent in terms of high strength, high rigidity, high temperature resistance&electrical insulation. they are used in the fields of electronics, electrical, optical fiber, automobile&aerospace. 2) liquid crystal fibers can be used for fishing nets, bullet proof clothing, sports goods, brake linings, optical fiber display materials, etc.,&can also be made into thin films for soft printed wiring, food packaging&so on. 3) lcp plastic materials have been used in microwave oven containers, which can withstand high&low temperatures. lcp can also be used for printed circuit boards, satellite electronic components&jet engine parts, for electronic&automotive parts/components,&for medical treatment. 4) lcp plastic raw materials can be filled with high filler as an integrated circuit packaging material instead of epoxy resin as the packaging material of the coil skeleton; as optical fiber cable connector sheath&high strength element; instead of ceramic as the filling material in the separation tower for chemical industry. 5) lcp plastic raw materials can also be made of alloy&polysulfone, pbt, polyamide blends of plastic parts molding, high mechanical strength, to replace the polysulfone glass fibre reinforced plastic, which can improve the mechanical strength,&can improve the use strength&chemical stability etc.. at present, the lcp is being used to use the outer panel of the space vehicle, the brake system of the car&so on.
the chemical properties of pa6 are very similar to that of pa66. however, the melting point is low&the range of process temperature is very wide. its impact resistance&resistance
the solubility is better than pa66, but it is also more hygroscopic. because many of the quality properties of the plastic parts are affected by the hygroscopicity, the pa6 is designed to be used.
the product should be fully considered when it comes to the product. in order to improve the mechanical properties of pa6, a variety of modifiers are often added. glass fiber is the most common
additives, sometimes in order to improve the impact resistance also added to synthetic rubber, such as epdm&sbr. for a product without additives, the contraction of pa6
between 1%&1.5%. adding glass fiber additives can reduce the shrinkage to 0.3% (but a little higher in the direction perpendicular to the flow).
the shrinkage rate of the formed assembly is mainly influenced by the crystallinity&hygroscopicity of the material. the actual shrinkage rate is also related to the design of plastic parts, wall thickness&other process parameters.
