FAQ
Q: Which PPS grade should I choose for my application?
For general structural parts needing high strength and stiffness choose glass fibre reinforced PPS (15-40% GF, e.g. KLD40D general purpose, KLD40L high flow). For precision parts needing low warpage choose glass fibre / mineral composite PPS (KLD57D, KLD67C). For high wear and low friction choose carbon fibre reinforced PPS (KLD30CF) or a PPS alloy (KLD30AS, KLD30SF). For electronic parts sensitive to chloride content choose the low-chlorine grade KLD40A66 (total chlorine < 900 ppm). Send us your service conditions and our engineers will recommend the matching grade.
Q: How is PPS priced, and why is there no list price?
Best Plastics quotes each order individually by grade, quantity, packaging and destination, through an enquiry form — we do not publish a single unit price on the website. The reason is that the cost of modified PPS varies widely with glass fibre loading and with impact modification, low-chlorine or carbon fibre options, and a single price would mislead buyers. State the grade, monthly volume and destination in your enquiry and we will reply with a tax-inclusive unit price, freight and the TDS of that grade.
Q: What is the lead time for PPS?
Standard grades are held in stock and ship 3-5 working days after order confirmation. Grades requiring custom compounding or colour matching take about 10-15 working days from formula confirmation to shipment. Export orders need additional customs clearance and booking time, normally 5 working days on top of the standard lead time.
