PPS (Polyphenylene sulfide)

What is PPS (Polyphenylene sulfide)?

It is one of the most stable plastic materials at high temperatures and is used in technical and industrial applications where other plastics do not meet the requirements.

Important properties of PPS (Polyphenylene sulfide)

• Extremely high temperature resistance – Can be used continuously at temperatures up to 200–240°C without losing its mechanical properties.
• Exceptional chemical resistance – Resists strong acids, bases, solvents and fuels, making it ideal for chemical processes.
• High dimensional stability – Shrinks minimally with temperature changes, which is crucial for precision components.
• Flame retardant – Naturally self-extinguishing and meets many fire ratings without added flame retardants.
• Electrically insulating – Has good dielectric properties and is used in electronics and electrical components.
• Durable and mechanically strong – Retains its stiffness and strength even at high temperatures.
• Low water absorption – Retains its properties even in humid environments.
• Resistant to UV and weather influences – Can be used in outdoor environments without breaking down.

Different types of PPS (Polyphenylene sulfide) and their uses

• Pure PPS – Used in electronics, medical devices and chemical processes.
• Glass fiber reinforced PPS – Increased stiffness and heat resistance, used in the automotive and aerospace industries.
• Carbon fiber reinforced PPS – Extra mechanical strength and wear resistance, used in technical components and high-strength applications.
• Flame retardant PPS – Meets strict fire protection requirements and is used in electrical components and wiring.

How do we use PPS in our production?

We use PPS in advanced applications where high heat and chemical resistance are required.

Some of the most common uses are:

• Electronics and electrical components – PPS is used in connectors, connectors and circuit boards where high temperatures and electrical insulation are important.
• Automotive industry – Used in fuel systems, sensors and engine components where the material is exposed to high temperatures and chemicals.
• Aerospace industry – PPS is used in components where low weight and extreme temperature resistance are required.
• Medical technology – Thanks to its chemical resistance, PPS is used in sterile medical components and surgical instruments.
• Chemical process equipment – PPS is used in valves, pump housings and pipelines where it is exposed to aggressive chemicals.

Why do we choose PPS (Polyphenylene sulfide)?

PPS is one of the highest-performance plastic materials on the market. Its unique properties make it indispensable in applications where extreme temperatures, chemical resistance and mechanical strength are required.

To optimize PPS for specific needs, it can be modified with:

• Glass or carbon fiber reinforcement – For increased stiffness and strength.
• Antistatic additives – For the electronics and semiconductor industry.
• Flame retardants – To meet even stricter fire safety requirements.

In summary, PPS is one of the most stable and chemically resistant plastic materials and is used in industrial, electronic and medical applications.
