POLYPHENYLENE SULFIDE (PPS)

Polyphenylene sulfide (PPS) was discovered by a team of researchers led by Dr. Herman Staudinger at Hoechst AG (now part of Celanese Corporation) in Germany in the early 1940s. Dr. Staudinger, a pioneering polymer chemist, and his team synthesized PPS through the reaction of p-dichlorobenzene with sodium sulfide.

PPS is known for its excellent chemical resistance, thermal stability, and mechanical properties, making it suitable for a wide range of applications, including automotive parts, electrical components, and industrial equipment. The discovery of PPS contributed significantly to the advancement of high-performance polymers and their practical applications in various industries.

BPY aren’t afraid of a challenge, pictured above are components for a valve in the oil and gas industry. With thick wall sections and critical dimensions, glass filled PPS was the perfect choice for this project.

Why choose PPS for your injection moulding project?

  • 1. High Heat Resistance: PPS is resistant to high temperatures, making it ideal for applications that require heat resistance.
  • 2. Chemical Resistance: PPS is also resistant to a wide range of chemicals, including many acids and bases.
  • 3. Dimensional Stability: PPS has low shrinkage and excellent dimensional stability, making it ideal for precision injection moulding applications.
  • 4. High Strength and Stiffness: PPS offers high strength and stiffness, making it a good choice for structural components in various industries.
  • 5. Low Water Absorption: PPS has low water absorption, making it suitable for use in wet environments.
  • 6. Electrical Insulation Properties: PPS has excellent electrical insulation properties, making it ideal for electronic and electrical applications.
  • 7. Recyclable: PPS is also recyclable, making it an environmentally friendly material.

Overall, PPS injection moulding offers a unique combination of properties that make it ideal for a wide range of applications, particularly those requiring high temperature and chemical resistance.
