ABS plastic physical properties: ABS plastic proportion: 1.05 g/cm3, molding shrinkage rate: 0.4-0.7%, molding temperature: 200-240℃, drying conditions: 80-90℃ for 2 hours

Characteristics of ABS plastic:

1. Good overall performance, high impact strength, chemical stability, and good electrical properties;

2. It has good weldability with 372 plexiglass, made of two-color plastic parts, and can be chrome-plated and painted;

3. There are high impact resistance, high heat resistance, flame retardant, reinforced, transparent and other levels;

4. The fluidity is a little worse than HIPS, better than PMMA, PC, etc., and it has good flexibility.

Use of ABS plastic: suitable for making general mechanical parts, wear-reducing and wear-resistant parts, transmission parts and telecommunications parts.

Molding characteristics of ABS plastic:

1. Amorphous material, medium fluidity, high moisture absorption, and must be fully dried. Plastic parts that require gloss on the surface must be preheated and dried for a long time at 80-90 degrees for 3 hours;

2. It is advisable to use high material temperature and high mold temperature, but it is easy to decompose when the material temperature is too high (the decomposition temperature is >270 degrees). For plastic parts with higher precision, the mold temperature should be 50-60 degrees, which is resistant to high gloss and For thermoplastic parts, the mold temperature should be 60-80 degrees;

3. If you need to solve the water pattern, you need to improve the fluidity of the material, take high material temperature, high mold temperature, or change the water level, etc.;

4. If heat-resistant or flame-retardant materials are formed, plastic decomposition products will remain on the surface of the mold after 3-7 days of production, which will cause the surface of the mold to become shiny, and the mold must be cleaned in time, and the mold surface needs to increase the exhaust position.

ABS resin is a polymer with a large output and a wide range of applications. It organically unifies the various properties of PS, SAN and BS, and has excellent mechanical properties of toughness, hardness and rigidity. ABS is a terpolymer of acrylonitrile, butadiene and styrene. A stands for acrylonitrile, B stands for butadiene, and S stands for styrene.

ABS plastic is generally opaque, and the appearance is light ivory, non-toxic, and tasteless. It has the characteristics of toughness, hardness and rigidity. It burns slowly, and the flame is yellow with black smoke. After burning, the plastic softens and scorches, giving off a special Cinnamon smell, but no melting and dripping phenomenon.

ABS plastic has excellent comprehensive properties, excellent impact strength, good dimensional stability, electrical properties, abrasion resistance, chemical resistance, dyeability, and good molding processing and mechanical processing. ABS resin is resistant to water, inorganic salts, alkalis and acids. It is insoluble in most alcohols and hydrocarbon solvents, but easily soluble in aldehydes, ketones, esters and some chlorinated hydrocarbons.

Disadvantages of ABS plastic: low heat distortion temperature, flammable, and poor weather resistance.
