ABS plastic, features and introduce the basics

Chemical Name: acrylonitrile - butadiene - styrene copolymer 

English name: Acrylonitrile Butadiene Styrene 

weight: 1.05 grams / cubic centimeter molding shrinkage rate 0.4-0.7% 

molding temperature :200-240 ℃ drying conditions :80-90 ℃ 2 hours 

Features: 

1, overall performance is better, high impact strength, chemical stability, good performance. 

2, and 372 glass melt was good, made of two-color plastic parts, and can be chrome plated, paint treatment . 

3, there are high impact, high heat resistance, flame retardant, enhanced level of transparency and so on. 

4, more mobile than HIPSAlmost, than PMMA,PCSo good, good flexibility. 

Uses: suitable for production of general machinery parts, less wear resistant parts, transmission parts and telecommunication parts. 

forming characteristics: 

1. amorphous material, liquid medium, moisture large, must be fully dry the surface gloss of the plastic parts required to be a long time dry and warm 80-90 degrees, 3 hours. 

2. should take the high melt temperature, higher mold temperature, but the expected high temperature and easily decomposed (decomposition temperature> of 270 degrees). on the high precision plastic parts, die temperature was take 50-60 degrees, high gloss. heat-resistant plastic parts, mold temperature 60-80 degrees should take. 

3, For address folder watermarks, need to improve the flow of materials, materials to high temperature, high mold temperature, or changed into water and other methods. 

4, such as forming heat-or flame retardant grade material, the production 3-7 daysMoldDecomposition of residual plastic surface, resulting inMoldShiny surface will take onMoldTime to clean up, while the surface of die need to increase the exhaust position.

 

    ABSResin is the largest output, the most widely used polymer, it willPS,SAN, BS in organically integrate various functions, both tough and hard, just with the excellent balance of mechanical properties.ABSIs acrylonitrile, butadiene and styrene copolymer, A representative of acrylonitrile, B on behalf of butadiene, S on behalf of styrene.

 

ABSEngineering PlasticsUsually opaque, pale ivory appearance, non-toxic, tasteless, both tough, hard, just the characteristics of the slow burning flame yellow with smoke, burned plastic softening, char, issued a special cinnamon smell , but no melt drip phenomenon.

 

ABSEngineering PlasticsExcellent overall performance, with excellent impact strength, good dimensional stability, electrical properties, wear resistance, chemical resistance and dyeing, molding and machining better. ABS resin, water, salt, alkali and acid, insoluble in most alcohols and hydrocarbon solvents, but easily soluble in aldehydes, ketones, esters and certain chlorinated hydrocarbons.

 

ABSEngineering PlasticsDisadvantages: a lower heat distortion temperature, fuel, weather is poor.
