Property: PPS has advantages of high temperature resistance, corrosion resistance, rediation resistance, flame retardance, average mechanical properties, excellent dimensional stability and electrical properties as well. With these outstanding properties, PPS composites have already been as substitutes for certain metals in structural material, automobiles, chemical machinery, aviation & aerospace, as well as the military industries.
This is the glass fiber and mineral filled polyphenylene sulfide compounds provide good mechanical strength with good flow and low maintenance molding using conventional molding equipment.
We provied the PPS R-4,R-7 grade of Solvay.
