What is Polyphenylene Sulfide (PPS)?

Polyphenylene sulfide (PPS) is a partially crystalline, high-temperature, high-performance polymer widely used due to its high melting point and inherent flame retardancy. PPS is one of the most “metallic” polymers known, making it ideal for harsh environments due to its excellent chemical resistance. PPS resin is an organic polymer composed of aromatic rings linked by sulfide bonds. Due to its unique structure, PPS plastic exhibits excellent chemical resistance and good mechanical strength. Its chemical resistance and tensile strength remain stable even at temperatures above 200°C. Furthermore, PPS has low water absorption, resistance to hot water and steam, and good dimensional stability. PPS polymer also possesses excellent dielectric and insulating properties, remaining stable under various conditions, and is inherently flame-retardant.

PPS Grades and Properties

General purpose PPS exhibits excellent heat resistance, with a heat deflection temperature of approximately 95°C. It possesses good chemical inertness and high resistivity. Its tensile strength is approximately 75 MPa, and it has moderate impact strength.

Reinforced PPS offers superior mechanical properties. Its tensile strength reaches approximately 110 MPa, and dimensional stability is also improved. It has a higher heat deflection temperature, typically reaching approximately 220°C. Furthermore, this grade of product also exhibits good chemical resistance.

Flame retardant PPS is designed to resist combustion and reduce smoke emissions. It maintains good electrical properties, with a tensile strength of approximately 85 MPa. Its heat deflection temperature is approximately 180°C.

Conductive PPS is conductive, making it suitable for electrostatic discharge (ESD) protection applications. It exhibits good chemical resistance, a tensile strength of approximately 95 MPa, and a heat deflection temperature of approximately 160°C.

Glass fiber reinforced polyacrylonitrile (PPS) is reinforced with glass fibers, improving both stiffness and strength. It boasts tensile strengths up to approximately 150 MPa, heat distortion temperatures up to 260°C, and low shrinkage.

PTFE additives reduce the coefficient of friction, making it ideal for bearings and wear-resistant applications.

Carbon fiber enhances the stiffness and thermal conductivity of PPS, improving its performance in high-temperature applications.

The combination of glass and mineral fillers achieves a balance of strength, stiffness, and cost-effectiveness.

These grades contain lubricant to reduce friction and wear in bearing applications.

Strict Pre-Production Quality Control Procedures

As part of our overall quality management process, all production equipment must be thoroughly disassembled and cleaned after the last production run before being put into operation. Our standard procedures go far beyond simple cleaning, as cleaning cannot remove all residual materials. The screw, barrel, and any other surfaces that come into contact with the molten polymer are thoroughly cleaned to ensure no cross-contamination occurs when a new PPS production line is started up. Furthermore, we equip each resin with a dedicated dryer to avoid mixing incompatible materials.

Custom Injection Molding Options for PPS Plastic Products

Injection molding of PPS plastic products and parts requires specialized, customized solutions to meet demanding industrial requirements. Below are our customization options for PPS plastic product injection molding.

PPS Materials injection molding parts

Mold Design Flexibility

Our engineers create custom molds using heat-resistant steel cores and optimized heat dissipation channels for precise thermal control. For high-volume orders, we offer multi-cavity molds with hot runner systems. We adjust gate positions and vents to prevent burn marks during high-temperature cycling. Modular mold designs enable complex geometries such as thin walls (as low as 0.5 mm) or undercuts.

Surface Finish and Post-Processing Options

You can choose textured surfaces, polished surfaces, or custom branded surfaces. Secondary processing techniques such as ultrasonic welding points or EMI/RFI shielding layers can also be integrated. All surface finishes undergo thermal cycling testing to verify their durability under repeated high temperatures.

Quality Inspection of PPS Injection Molded Parts

Depending on project requirements (tolerances or surface finish), we offer comprehensive quality inspection capabilities for molded PPS plastic parts. We begin by visually inspecting the surface of the molded parts for defects such as color difference, shrinkage marks, and texture variations. The aim is to meet your requirements for both appearance and function. For precision PPS plastic parts, we typically use a coordinate measuring machine, vernier calipers, micrometers, and height gauges to verify that the critical dimensions of the plastic parts meet specified tolerances. For projects requiring material property testing, we offer tensile strength testing, hardness testing, and other relevant mechanical property checks to confirm the resin’s performance under load or stress.
