what is a pps
What is PPS? Polyphenylene Sulfide (PPS) Polymer Characteristics. PPS is an engineering polymer whose structure is composed of benzene and sulfur. Polyphenylene sulfide (PPS) is a partially crystalline, high temperature performance polymer that has the chemical structure shown in the figure on the right. This polymer has a high melting point of approximately 280Â°C, excellent chemical resistance and is inherently flame retardant.
