PPS plastic raw material English Name: Phenylenesulfide weight: 1.36 g / cubic centimeter molding shrinkage: 0.7% molding temperature: 300-330 DEG C. It is a kind of thermoplastic engineering plastics with excellent comprehensive properties, which is characterized by high temperature resistance, corrosion resistance and superior mechanical properties. In the chemical industry can be used as PPS synthesis, transport, storage tank, pipeline, valve, reaction chemical pumps, making blade gear, an eccentric wheel, bearing, clutch and wear parts in machine center pps;
TPEE major brand TPEE5556:Hytrel? 5556 is medium modulus and nominal hardness 55D class. It contains stability without discoloration. It can be treated like many traditional injection molding and extrusion thermoplastic processing technologies. TPEE4056:Hytrel? 4056 is a low modulus Hytrel? 40D nominal hardness, hardness grade. It contains a stability that does not change color. It is recommended for extrusion and compounding. TPEE4556:Hytrel? 4556 is of medium modulus and nominal hardness of 45D. Stable and thermoplastic with TPEE 5556. TPEE5526:Hytrel? 5526 is a medium modulus Hytrel? nominal hardness, hardness class 55D.

TPE extrusion of finished products, surface roughness, molding temperature is low, increase temperature, back pressure and screw speed, mold temperature is too low, improve mold temperature
Product surface into a block phenomenon of feeding pipe is not clean?or?debris to clean material additives such as color masterbatch?or?carrier according to the requirements for the corresponding color
Products die after expansion die temperature is too low,?or?too fast increase screw speed, die temperature, screw speed, reduce the material limiting excessive adjustment of material limiting device
Extrusion produced large amounts of gas to reduce the temperature of high temperature material pipe cleaning pipe
Products have shrunk in raw materials containing moisture drying melt temperature, screw speed too fast to reduce temperature, reduce the speed of the screw.
