1. ABS Characteristics, uses and processes of 12 types of plastics such as ABS, PP, PC and PET that everyone should know.

Acrylonitrile Butadiene Styrene (ABS) is a thermoplastic synthetic polymer resin that is well balanced and can be tailored to specific needs. Its main physical properties are: hard and solid. ASS brand resins are flexible like elastomers (or rubber). Among them, polybutadiene provides good compressive strength, amorphous styrene thermoplastics make ABS easier to process (flow easier in mold), and acrylonitrile improves strength, hardness, and corrosion resistance.

Effective control of these three components allows designer to define degree of elasticity according to needs of final product. Perhaps because of this, ABS can be widely used in household and white products. While not as strong as other engineering polymers, it is cost effective.

3. Polymethyl methacrylate (PMMA)

Characteristics, uses and processes of 12 types of plastics such as ABS, PP, PC and PET that everyone should know.

Acrylic was first developed in 1930s when it was primarily used in safety glass rotators. Acrylic was first registered in 1934 and is known as plexiglass. Transparency and lightness are perfectly combined, which makes it an interesting new plastic. By 1960s, this material was being discovered by avant-garde furniture designers and applied to interiors, such as contemporary furniture.

Because acrylic is available in a variety of colors, its functionality has naturally expanded from lighting to making signage for companies. All international brands now use this material for signage. The acrylic surface is hard and recognizable as glass from a distance. It can be made into thin sheets by injection molding and extrusion to meet requirements of various applications. Cast acrylic flakes can be used as high quality glass and are suitable for mass production.

The high molecular weight makes it very strong, flexible and easy to handle and manufacture. This method of casting production is ideal for large productions and painting small batches. Extruded flakes have a lower molecular weight, so they are easier to pump. The extrusion molding process provides excellent thickness stability to product and also makes it very cheap to mass produce.

8. Silicone polymer

Characteristics, uses and processes of 12 types of plastics such as ABS, PP, PC and PET that everyone should know.

In 1943, Scottish engineer James Wright used test tubes to test mixtures in laboratory of General Electric Company in Connecticut, USA. He accidentally mixed boric acid and silicone oil to "polymerize" them. Wright tossed some on floor, sucking sticky mixture out of vial. Surprisingly, substance bounced off floor, and an elastic putty was born.

Wright set out to find a practical use for his invention, and finally SillPutty™ Playdough made its debut at New York International Toy Festival in 1950. After persistent efforts, some major toy distributors have decided to distribute SillPuttyTM, and rest are well known.
