What is ryton PPS?
What is ryton PPS?
Ryton® polyphenylene sulfide (PPS) is a semi-crystalline, high-heat polymer that offers exceptional dimensional stability for precision-molded components needing to withstand prolonged, high-temperature service. It is inherently flame retardant and offers chemical resistance comparable to PEEK and fluoropolymers.
Is Ryton a plastic?
Polyphenylene Sulfide (Ryton® PPS) is an engineered thermoplastic, that offers an exceptional balance of properties. PPS has a high-temperature resistance, chemical resistance, flowability, and dimensional stability. This makes PPS a useful material in electronics, automotive, aerospace, and chemical industries.
Is Ryton Food Safe?
The third—Ryton R-4-232 PPS—is a previously available product that is now proven safe for food contact. Ryton PPS compounds offer best-in-class long-term heat resistance combined with excellent dimensional stability, very low moisture absorption, strong chemical resistance and inherent flame retardancy.
What is Ryton made of?
Ryton® / Techtron® / PPS (polyphenylene sulfide) Ryton®(PPS) is a glass reinforced material offering extremely high strength, in addition to excellent chemical resistance properties.
Who makes Ryton?
Ryton® PPS was first commercially produced in 1972 by Phillips Petroleum making it the first of the high strength, high temperature melt-processable polymers. Ryton R4, a 40% glass fiber reinforced grade that was the “go to” polymer when high strength in aggressive service conditions existed.
Is PPS food Safe?
Engineered for food and beverage applications, Solvay food-safe Ryton polyphenylene sulfide (PPS) polymers are suitable for applications such as food-industry appliance components that operate at temperatures up to 392°F, including parts for deep-oil fryers, coffee machines, ovens and microwaves.
What is PPS Fibre?
Polyphenylene sulfide fibers (PPS) are high-performance, semi-crystalline fibers with exceptional chemical and heat resistance, high dimensional stability, low moisture absorption, and high resistance to hydrolysis when exposed to acids, alkalines, and organic solvents.
Is PPS toxic?
Environmental precautions: PPS resin is a stable organic thermoplastic and a hazardous polymerization will not occur.
What kind of chemical resistance does RYTON PPS have?
Most Ryton® PPS compounds have UL94 V-0 flammability ratings without flame retardant additives. The chemical resistance of Ryton® PPS is well known to be outstanding, even at elevated temperatures. However, being an organic polymer, PPS can be affected by some chemicals under certain conditions.
What are the thermal properties of Ryton rubber?
As shown in the table below, UL thermal indices for Ryton® PPS go up to 240 °C (464 °F). Even complex parts can be molded with very tight tolerances and will maintain dimensional stability even at elevated temperatures and in harsh chemical environments.
Which is the bearing grade for Techtron PPS?
Techtron® PPS PS BG (Bearing Grade) Techtron® PPS PS BG (Bearing Grade) is an internally lubricated, carbon-fiber reinforced, compression-molded PPS that offers a low coefficient of thermal expansion and uncompromised chemical resistance. It is well suited for thrust or wear applications or when an electrically conductive material is required.
Which is better Techtron PPS or reinforced PPS?
Techtron® PPS is an unfilled and extruded grade of PPS. Unlike reinforced PPS products, Techtron® PPS is easily machined to close tolerances. It is the material of choice for structural applications in corrosive environments or as an alternative to PEEK at lower temperatures.
