What are the commonly used materials for household electrical appliances?
PSGP modified polystyrene 204The transparency of 88-92%, refractive index 1.59-1.60, suitable for light products, dyeing is strong, non-toxic and tasteless, no fungus growth, high impact strength, resistance to acid and alkali resistant performance is good, not on the basis of solvent, excellent electrical properties, easy molding, moisture less than 0.02% can maintain the strength and size of high humidity, but the brittleness.Suitable plastic products: decorations, lighting signs, lampshades, stationery, transparent toys, daily necessities, instrument lenses, freezers and thermal insulation in the refrigerator (after foaming).Other: the shrinkage rate of 0.4-0.6% suitable thickness 1.5-3mm.
As a general material used, large output, low price, performance in general, manufacturers more. It can be added stabilizer, glass fiber and other materials to modify the general plastic, and strengthen the application performance, but it is far less than the performance of Engineering plastics.AS (SAN) acrylic styrene transparent adhesiveAS is acrylonitrile (A), styrene (S) copolymer, weather resistant medium, not by the high humidity environment, ability, general oil, detergent and mild alcohol, poor fatigue resistance, not easy to crack due to stress, material quality high transparency, good liquidity in abs.Suitable plastic products: tray, cups, cutlery, toothbrush, refrigerator cabinet, knob, lighting accessories, accessories, instrument mirror, packing box, stationeryOther: shrinkage 0.2-0.7%, suitable wall thickness 1.5-3mm
PSHI high impact polystyreneThe component has rubber, the impact strength is greatly improved, the product can be designed buckle and column position, and the column can also be self tapping screw, in 85 degrees for a long time, aging accelerated, life reduced.Suitable plastic products: all kinds of household appliance housings, stationery, toys, electronic parts, electronic instrument shells, refrigerators and refrigerators, shells, telephones.Other: the shrinkage rate of 0.4-0.7% suitable thickness 2-3mm. Overflow value 0.03mm
PP polypropylene fold gumLike a white waxy, more transparent and more light than polyethylene, liquidity injection, water absorption of less than 0.02%, chemical organic solvent, concentrated nitric acid sulfuric acid is very stable in many external medium, high impact strength and yield strength is very high, high frequency electric performance is not good, easy to shrinkage, high temperature resistance, low temperature brittleness, wear resistance is not high.Suitable plastic products: general structural parts, corrosion resistant parts, heated electrical insulation parts. All kinds of household articles, stationery, toys, chemical containers, medical supplies.Other: the shrinkage rate of 1.0-3.5% with 30% glass fiber can be improved to 0.7% 1.5-2.5mm thick around the right. Overflow value 0.03mm
