Polyphenylene Sulfide (PPS)

Polyphenylene sulfide (PPS) polymer is a semi-crystalline, high-heat resistance thermoplastic engineering plastic. Types of PPS compounds include both the cross linked and linear type.

What’s PPS polymer?

Polyphenylene sulfide (PPS) is a polymer formed by the substitution pattern of the sulfur atom and the phenyl ring in the para position. The molecular structure of its molecular structure contains a high degree of stability of chemical bonds, so that the thermal degradation and chemical reactions have a high molecular stability. At the same time, the molecular structure of the polymer is also easy to form a crystal lattice with thermal stability, therefore, PPS is a crystal melting point up to 285°C(545°F) about the semi crystalline polymer. Due to the characteristics of its molecular structure, PPS is usually formed in the combustion of carbon residue, so that the material has the inherent flame retardant properties. PPS has not been found in less than 200°C(392°F) or so, soluble in any solvent.

Features of Sciengy® PPS

● Heat resistant

Outstanding long-term and short-term heat resistance properties, the long-term tolerance of up to 200°C (392°F) of the temperature, and the short-term maximum tolerance of 260°C(500°F).

● Chemical resistance

Outstanding chemical resistance to a wide variety of aggressive chemical environments, comparable to PEEK and fluoropolymers. Resist acid, alkali, chlorinated hydrocarbons, alkanes, ketones, alcohols, esters and other chemicals in the erosion, etc. 

● Flame retardant

Several grades passed the UL testing program, Conforms with UL94V-0 without inclusion of flame retardant agents (UL File No. E493853).

● Electrical properties

Outstanding electrical properties at high temperature, high humidity and high frequencies. Dielectric and insulating properties stable over a wide range of conditions.

● Dimensional stability

With low molding shrinkage and linear coefficient of thermal expansion as well as very low moisture absorption, excellent dimensional stability is maintained even at high temperatures and high humidity.

● Abrasion resistance

By filling the carbon fiber, aramid fiber, fluorine resin and other lubricants, can greatly reduce the friction coefficient and wear, offer excellent wear coefficient and good self lubrication performance.

● Mechanical properties

Offer high strength, high modulus and high rigidity even at high temperatures, and outstanding anti-fatigue and anti-creep properties.

● Excellent processability

Outstanding fluidity specifications enable injection molding of thin-walled parts, while special modified specifications with high viscosity enable extrusion molding of large-diameter pipelines and thin-walled tubes, sheets and rods etc.
