The difference between PS material and ABS material performance?

PS plastic (polystyrene), material properties: electrical insulation (especially high frequency insulation) fine, colorless and transparent, translucent rate second only to organic glass, color of the water resistance, good chemical stability,. Intensity general, but the crisp, easy to produce brittle fracture stress, impatience benzene.Suitable for making gasoline and other organic solvents. Insulating transparent.Garnish and chemical instrument. Optical instrument parts such as: 1. Forming properties of amorphous material, moisture absorption is small, do not need to fully dry, not easy to decompose, but the coefficient of thermal expansion, internal stress is easy to produce. Good fluidity, available screw or plunger type injectionmolding machine is suitable for high temperature.2., high mold temperature, low injection pressure, injection time is prolonged helps reduce stress, prevent theshrinkage deformation.3. with various forms of gate, gate and plastic arc connection, so as to avoid damage to the gate of plastic parts. Draft, out ofuniform. Plastic parts wall thickness, it is best not to take insert, such as insertsshould be preheated.

ABS (acrylonitrile butadiene styrene), light yellow granular or bead-like resin opaque, non-toxic, tasteless, low water absorption rate. Have excellent mechanical properties, excellent low temperature impact performance, excellent electrical properties, abrasion resistance, dimensional stability, chemical resistance, dyeability. Easy molding processing. ABS water, inorganic salts,alkalis and acids, alcohols and insoluble in most solvents, soluble in aldehydes,ketones, esters and certain chlorinated hydrocarbons in. The disadvantages of ABS are combustible, thermal deformation temperature is low, poor weather resistance. Combustion characteristics: flammable; from the fire continues to burn; flame yellow, thick smoke; softening, foaming; acrylonitrile taste. Solubility: soluble solvent: dichloromethane; insoluble solvents: alcohols, aliphatic hydrocarbons, water. Application: automobile industry, mechanical equipment,electronic appliances etc..
