PPSIt is a polymer containing repeating structural units of p-phenylene sulfide in its molecule. PPS is a new type of functional engineering plastic.
PPS application:
It can be used as a filter fabric for industrial coal-fired boiler bag filter chambers, and as a binder for glass, steel, ceramics, aluminum, silver, chrome-plated and nickel-plated products.PPS is widely used in the manufacture of electrical parts, auto parts, precision instrument parts, various model products and laminated materials, etc.
PPS plasticIt is a thermoplastic special engineering plastic with excellent comprehensive properties. PPS is characterized by high temperature resistance, corrosion resistance and superior mechanical properties.PPS is a sulfur-containing aromatic polymer. Linear PPS becomes a thermosetting plastic after cross-linking above 350°C. Branched chain structure PPS is a thermoplastic plastic.
Polyphenylene sulfide PPS is a new type of high performance thermoplastic resin Polyphenylene sulfide PPS is a crystalline polymer.The unstretched fiber has a large amorphous region (crystallinity is about 5%), PPS crystallization exotherm occurs at 125 °C, the glass transition temperature is 93 °C; melting point is 281 °C.The stretched fiber produced partial crystallization during the stretching process (increased to 30%). If PPS heat-treated the stretched fiber at a temperature of 130-230°C, the crystallinity could be increased to 60-80%.Therefore, the stretched fiber has no obvious glass transition or crystallization exotherm, and its melting point is 284 °C.With the increase of crystallinity after stretching and heat setting, the density of fibers also increases accordingly, from 1.33g/cm3 before stretching to 1.34g/cm3 after stretching, and PPS can reach 1.38g/cm3 after heat treatment
★PPS features:It is a high-performance plastic specially developed for the semiconductor industry.Especially in combination with excellent wear resistance and sliding properties, PPS material is suitable for CMP (chemical mechanical planarization/polishing) applications.In addition, PPS polymers combine excellent mechanical properties with high thermal and chemical resistance.
★PPS use:It can be used as a filter fabric for industrial coal-fired boiler bag filter chambers, and as a binder for glass, steel, ceramics, aluminum, silver, chrome-plated and nickel-plated products.Widely used in the manufacture of electrical parts, auto parts, precision instrument parts, various model products and laminated materials, etc.
★PPS features:Linear polyphenylene sulfide is a partially crystalline material that offers very high mechanical properties combined with excellent thermal and chemical resistance (continuous use up to approximately +464°F), high dimensional stability and creep strength.Its LOI is the highest among polymers.With its strength and affordability, it bridges the gap between partially crystalline industrial plastics and PEEK.Thanks to 40% glass fiber reinforcement, a strength comparable to light metals is achieved.
★PPS use:Assembly of equipment construction, pump parts, fan elements, impellers, valve balls/seats/seals, plastic parts and motor vehicle components.
