![]() ■ Very complex, high precision molding is achievable ■ Advanced electrical properties under high heat, high humidity, high frequencies ■ Chemical resistance second only to fluorinated polymers (PTFE) ■ Excellent dimensional stability under most environmental conditions ■ PPS polymer is inherently UL V-0 (self-extinguishing) ■ Maintains strength and high rigidity over wide temperature ranges ■ Heat resistance that makes continuous usage possible at 200☌ or higher Versus traditional materials, such as steel or thermoset polymers, DIC.PPS products have the engineering features required to benefit component designers, tool designers and polymer process specialists which are seeking a truly engineered product. Because the linear polymer exhibits high purity, it is less prone to absorbing moisture under high heat and humidity conditions compared to the cross-linked polymer.Īs a result, DIC.PPS product portfolio contains a wide variety of engineered products that can be custom formulated to meet the most demanding performance requirements. The other type is based on a linear PPS polymer and has the desirable features associated with tensile elongation and impact resistance. This type delivers unique benefits associated with resistance to creep deformation. The branched PPS polymer exhibits high rigidity under elevated temperature conditions. However, it also exhibits superior elevated temperature resistance, advanced mechanical properties and excellent dimensional stability designed to meet demanding tight tolerance applications.ĭIC.PPS is broadly classified into two families of polymer – chemically branched and linear polymer. DIC.PPS, an engineering compound formulated with both glass fiber and/or mineral filler, features the characteristics of a typical engineering thermoplastic.
