Polystyrene (PS) injection molding: properties, processing and mold design points

Polystyrene (PS) is one of the most widely used thermoplastics in industrial production. Since its commercialization by BASF in Germany in the 1930s, this material has been widely adopted in industries such as packaging, home appliances, medical devices and prototyping due to its high rigidity, transparency and good processability. While it is commonly used in …

Polycarbonate (PC) Material: Properties, Advantages, and Applications

Polycarbonate (Polycarbonate, referred to as PC) is a transparent engineering thermoplastics, both high impact strength, good heat resistance and optical transparency. Since its industrialization in the late 1950s by Germany’s Bayer (Bayer, trade name Makrolon) and the U.S. General Electric Company (GE, trade name Lexan), polycarbonate has become a representative material for transparent structural parts. …

Polypropylene (PP): Definition, Types, and Properties

Polypropylene (PP) is currently the second most used thermoplastic polymer in the world, after polyethylene (PE). Due to its low density, chemical resistance, recyclability and cost-effectiveness, PP has become one of the most commonly used general engineering plastics in manufacturing.

Whether it’s packaging film, automotive bumpers, medical devices and chemical piping, polypropylene materials are lightweight …

What is Ultra High Molecular Weight Polyethylene (UHMWPE)?

Ultra-high molecular weight polyethylene (UHMWPE) is an engineering plastic with extremely high molecular weight, usually between 2 million and 6 million. Due to its special molecular structure, UHMWPE has excellent wear resistance, low coefficient of friction, high impact resistance and excellent chemical stability, and is widely used in many demanding industrial fields. With the continuous …
