Overview of PPS Modification

Polyphenylene sulfide (PPS) is one of the most cost-effective special engineering plastics. It has become a large variety of special engineering plastics and is also known as the sixth largest engineering plastic.

In recent years, due to the continuous update and improvement of synthesis technology, the application field of PPS has also been continuously expanded. There are many grades of PPS, and the molding methods include injection molding, extrusion, sintering, pressing, calendering, etc., which can be precisely molded, and the plastic parts can be subjected to secondary processing. PPS has very significant advantages. Its heat resistance, insulation and flame retardancy are excellent in various properties, and its hardness and strength are high.

PPS is an indispensable new material for the renewal of traditional industries and the development of high-end technology. In many aspects, it is gradually replacing thermosetting resins such as metals and epoxy phenolic resins. PPS is generally seldom used alone, and is mostly based on composite materials with inorganic fillers or GF, and is mainly used in the field of injection molding. PPS has good tensile and flexural strength and is a medium-level engineering plastic, but its elongation at break and impact strength are low. Therefore, it usually maintains its outstanding characteristics such as heat resistance, flame retardancy and chemical stability. Under the premise, it is necessary to further improve and increase the toughness and strength of PPS resin so that it can meet various needs.
