Plastic is a common non-metallic material with excellent insulation properties and low cost. Plastics are commonly used in the manufacture of electronics, electrical appliances, and automotive parts. When selecting a plastic material, factors such as its physical properties, mechanical properties, temperature resistance, and processability should be considered. This article will focus on a selection of plastic materials to provide a reference for your selection.

ABS (Acrylonitrile-Butadiene-Styrene)

ABS is a terpolymer of acrylonitrile, butadiene, and styrene, and is the most widely used polymer. It organically combines the properties of PS, SAN, and BS, offering excellent mechanical properties with a balanced balance of toughness, hardness, and rigidity.

Colors:
White, Black, Beige

Features:
ABS shares the common properties of its three components:
A makes it chemically and heat-resistant, and possesses a certain surface hardness. It is unaffected by water, inorganic acids, and food acids and alkalis, and can be used in temperatures ranging from -50 to +70°C. It has excellent impact resistance at low temperatures and good shape and dimensional stability at warm temperatures.
B makes it highly elastic and tough. It has high mechanical strength and rigidity, is scratch-resistant, and offers tensile strength, chemical resistance, and high surface strength.
S gives it the processing and molding characteristics of thermoplastics and improves electrical properties. It is easy to color, process, and electroplating, and has excellent chemical and electrical insulation properties.

Disadvantages:
Weakly weather-resistant and easily affected by weather conditions, has limited acid and corrosion resistance,soluble in ketones, softens in chlorinated hydrocarbons, fats, aromatic compounds, and aldehydes.

Applications:
Model materials, such as architectural models, figurines, food industry parts, electronic components for the imaging industry, and refrigeration. In the electronics and electrical industry, ABS can be used to manufacture components such as antenna sockets, coil bobbins, terminal blocks, converters, speakers, and connectors.

POM (Polyoxymethylene)

POM is a thermoplastic engineering plastic with a high melting point and high crystallinity. It is the hardest among thermoplastics and one of the plastic materials with mechanical properties closest to metal, commonly known as polyoxymethylene.
