東莞市千泰塑膠原料有限公司為您提供tpv//121-70m350/織紗。tpv//121-70m350/織紗
tpv//121-70m350/織紗long term supply of pp resin&eva blend. the amount of the plasticizer can be varied from 5%-20% to obtain different characteristics. in the actual production, because of the modification of the material, it is necessary to add a variety of additives, therefore, in the blending process of the feeding sequence is also very important, otherwise the mixture can not achieve the desired results.
the shrinkage of pa66 is between 1%~2%,&the addition of glass fiber additives can reduce the shrinkage to 0.2%~1%. the difference between the direction of flow rate&the direction perpendicular to the flow direction is larger. pa66 is resistant to many solvents, but is less resistant to acids&other chlorinated agents.
pc / / pc / / 1010nh material: polycarbonate is a high strength transparent material, pc, is used in transparent product engineer product design of a commonly used material, is often injected into the every kind of transparent/translucent parts, can be used in automobile lamps etc.. a, raw material moisture - drying raw materials
b, poor exhaust -- improved die design
3, resin color, black
a, barrel, nozzle buildup - cleaning barrel&nozzle
b, forming high temperature - lowering molding temperature
4, not full of products
a, plasticizing enough -- increasing barrel temperature
b, lower die temperature - raising mold temperature
c, nozzle overflow - mold position adjustment
pom material can be used for a long time in the -40 to 100 deg c temperature range. pom easy deco-ition, deco-ition temperature is 280 deg c, deco-ition of irritation&corrosive gases. therefore, the choice of mold steel corrosion resistant materials. the mechanical properties of pom high strength&stiffness, good elasticity, good wear resistance&antifriction.
