PPS in Injection Molding
Polyphenylene Sulfide (PPS) is a high-performance engineering thermoplastic with chemical resistance and thermal stability properties. PPS is applicable in parts that require high dimensional stability, low moisture absorption, and resistance to chemicals and heat.
As a result, it is ideal for automotive, electrical, industrial, and aerospace applications, where performance under harsh conditions is critical. RapidDirect offers various PPS materials, including PPS Black, PPS White, and PPS+GF30 Black, to meet diverse injection molding needs.

Pros and Cons of PPS Injection Molding
PPS plastic offers many benefits that make it suitable for injection molding. However, there are some of its downsides to consider before choosing it for any project.
Pros
- Excellent chemical resistance and thermal stability.
- High mechanical strength and dimensional stability.
- Low moisture absorption and good electrical insulation.
Cons
- Higher processing temperatures are required.
- It can be brittle if not properly processed.
- More expensive than some other engineering plastics.
Applications of Injection Molded PPS Parts
Injection molded PPS parts are widely used across various industries, including:
- Automotive: Under-the-hood components, electrical connectors, and fuel system parts.
- Electrical and Electronics: Insulators, connectors, and housings.
- Industrial: Pump components, valves, and mechanical parts.
- Aerospace: Engine components, structural parts, and insulation
FAQs
To ensure proper flow and molding, PPS requires high processing temperatures, typically 2800C to 3200C. The mold temperature should also be maintained between 1300C and 1500C to achieve optimal crystallinity and mechanical properties.
PPS suits applications requiring high chemical resistance, thermal stability, and mechanical strength. It is widely used in the automotive, electrical, industrial, and aerospace sectors. If your application involves harsh chemical environments, high temperatures, or the need for dimensional stability, PPS is an excellent choice.
PPS offers excellent chemical resistance and thermal stability, like PEEK, but at a lower cost. While PPS is less expensive than PEEK, it may have slightly lower mechanical properties. PPS has superior chemical resistance and thermal stability compared to Nylon but may be more brittle.
When designing for PPS injection molding, consider factors such as uniform wall thickness to prevent warpage, appropriate gate design to ensure smooth material flow and adequate venting to avoid air traps. Additionally, account for the material’s shrinkage rate and ensure proper mold temperature control for optimal part quality.
