Polyphenylene Sulfide (PPS) is a high-performance engineering plastic with excellent temperature resistance, dimensional stability, and electrical insulation properties. With exceptional mechanical strength, chemical resistance, and flame resistance, PPS is commonly found in high temperature applications such as automotive parts, appliances, electronics, medical devices, and industrial applications.

What type of thermoplastic is PPS?
Polyphenylene sulfide (PPS) is a semi crystalline, high temperature engineering thermoplastic. It is one of the most important thermoplastics because it has an extremely stable molecular structure which lends to its performance in harsh chemicals. It exhibits a number of desirable properties including resistance to heat, acids, alkalines, mildew, bleaches, aging, sunlight, and abrasion.
How does machining PPS differ from metal machining? injection molding, or 3D printing?
Although each process has differences, plastic machining, 3D printing, and injection molding, overlap in their capabilities.
Why is PPS a good material for machining?
PPS is a fantastic material for machining. Its low shrinkage and stable dimensional properties make it easy to machine to incredibly tight, precise tolerances. Besides being more lightweight, plastics are also more cost-effective than raw metal materials used in part fabrication, in part due to the ability to be produced in faster cycles than metals.
