Correct processing of Polyphenylene Sulfide, aka PPS material, is critical in order to achieve the right properties for industrial use. Rebling employs innovative equipment to mold PPS material components in a fully crystalline state. PPS material is inherently flame retardant and can achieve UL 94 V0 ratings in wall thicknesses as low as .015 inches without the use of flame retardant additives. The shrinkage of PPS varies depending on the part wall thickness and the flow direction of the material during the molding process with shrinkage in the transverse flow direction two times greater than that in the flow direction, typical of crystalline materials. Extremely tight tolerances therefore may be more difficult to achieve when selecting a crystalline product like PPS material over an amorphous material which has uniform shrinkage in all directions.
