ABS-3D print materials

ABS-3D print materials
Let’s see another 3D print materials-ABS
Chemical characteristics

A good comprehensive performance, higher impact strength, chemical resistance, good electrical characteristics.

With 372 plexiglass weldability good, made of two-color plastic parts, and chromed, painted.
High impact, high heat resistance, flame retardant, reinforced, transparency and so on.
More mobile than HIPS almost than PMMA, PC, well, good flexibility.

Molding characteristics
1. amorphous material, liquid medium and moisture must be fully dry, surface gloss of plastics parts must longer preheating drying time 80-90, 3 hours.
2. suitable for high temperature, Gao Mowen, but temperature decomposition (decomposition temperature of >270 degrees). high precision plastic parts, mold temperature to take 50-60, of high gloss. heat-resistant plastics, mold temperature to take 60-80.
3, if you need to solve the Weld Line, need to improve its liquidity, high temperature, Gao Mowen, or change into water and other method .
4 heat resistant or flame retardant materials, such as forming, 3-7 days after the production mould surface remains plastic decomposition products, resulting in mold shiny surface, it is necessary to clean up mold and mold surface to increase the exhaust position.
Is currently the largest production of ABS resin, the most widely used polymer, it will PS,SAN,BS the properties of organic unity, both tough, hard, just balanced by excellent mechanical properties. ABS acrylonitrile, butadiene and styrene terpolymer, a representative of acrylonitrile, b for butadiene, s for styrene.
ABS plastic is opaque, the appearance of a pale ivory, nontoxic, tasteless, characteristic of both tough, hard, rigid, slow burning, yellow flame and black smoke, burning plasticsoftening, burning, make a special smell of cinnamon, but the phenomenon of melting or dripping.
ABS plastic with excellent performance, excellent impact strength, good dimensional stability, performance and wear resistance, chemical resistance, stain resistance, forming and machining ABS resin water, inorganic salts, alkalis and acids, insoluble in most hydrocarbon solvents and alcohol, easily soluble in aldehydes, ketones, esters and chlorinated hydrocarbons.
ABS plastics disadvantages: low heat distortion temperature, fuel, weather was poor.
