PPS

Overview

Polyphenylene Sulfide (PPS) is a semi-crystalline, high-temperature engineering Its chemical structure consists of para-phenylene aromatic rings linked by sulfide (–S–) bonds, giving it excellent heat and chemical resistance. Typical features of PPS: Melting point around ~280 °C. It is used where standard plastics (like PET, POM) are insufficient, bridging toward higher-performance materials (e.g., PEEK, PAI) but at a more moderate cost. PPS is processed by injection moulding, extrusion or machining of stock shapes, thanks to its good processability for an engineering polymer.

Characteristic

Thermal / Mechanical Stability
PPS maintains high mechanical strength and dimensional stability even at elevated temperatures.
Low coefficient of linear thermal expansion (CLTE) compared to many other engineering plastics.
Good creep resistance (i.e., less deformation under longterm load at high temperature) compared to many plastics.
Chemical & Moisture Resistance
Exceptional chemical resistance: stable to many strong acids, bases, solvents, fuels, oils, even under elevated temperature conditions.
Very low water absorption (≈ 0.02% in 24h immersion in some grades) → better stability in humid or wet environments.
Electrical & FlameRetardance
Good electrical insulation properties: high dielectric strength, high resistivity.
Inherent flame retardancy: many PPS compounds pass UL94 V0 without additional flame retardants.
Machinability / Processability
Available in grades (unfilled, glassfilled, mineralfilled) to tailor properties (mechanical strength, stiffness, dimensional tolerance).
Its semicrystalline nature and good dimensional stability make it suitable for precision parts.

Applications

Automotive & Aerospace: engine components, housings, connectors, thrust washers, parts that must resist high heat/chemical attack. Electronics & Electrical: connectors, insulators, electronic control modules, sensors, circuit board components where high temperature / flame retardant / precise tolerance is required. Chemical Processing / Industrial Equipment: pumps, valves, fittings, wear-resistant components in corrosive or high-temperature environments. Semiconductor Manufacturing & Precision Machinery: parts for semiconductor production equipment, special grades for tight tolerance / high purity. ensingerplastics.com Others: Bearings, gears, bushings, filters, down-hole oil & gas equipment, etc.
