Ps plastic English name: Polystyrene ps plastic properties specific gravity: 1.05 g / cm 3 molding shrinkage: 0.6-0.8% molding temperature: 170-250 ° C ps plastic - brief polystyrene (PS) plastic is an older Plastics, production processes have also been relatively complete. Compared with other plastics, PS has the characteristics of good transparency (light transmittance of 88%-92%) and surface gloss, easy dyeing, high hardness, good rigidity, and good water resistance and resistance. Chemical corrosive and processing flow properties. Its main disadvantages are: brittleness, low impact strength, easy stress cracking, poor heat resistance, etc. Ps plastic material performance electrical insulation (especially high frequency insulation) is excellent, colorless and transparent, light transmittance is second only to plexiglass, coloring water resistance, good chemical stability, general strength, but brittle, easy to produce stress brittle Cracked, not resistant to benzene, gasoline and other organic solvents. Suitable for making insulating transparent parts. Decorative parts and chemical instruments. Optical instruments and other parts.
Ps plastic molding performance 1. Amorphous material, small moisture absorption, no need to fully dry, not easy to decompose, but large thermal expansion coefficient, easy to produce internal stress. Good fluidity, can be molded by screw or plunger injection machine. High material temperature, high mold temperature, low injection pressure, prolonged injection time are beneficial to reduce internal stress and prevent shrinkage. Deformation. 3. Various types of gates can be used, and the gate is connected with the plastic part arc to avoid going to the gate. Damaged plastic parts. The draft is large and the top is evenly distributed. The wall thickness of the plastic parts is even, preferably without inserts. If there are inserts, it should be preheated. ps plastic use electronic appliances: can be used to manufacture TV sets, tape recorders and Electrical instrument parts, housings, etc.
