What material is the pps?

High-performance polymers are finding increasingly widespread application in various commodity sectors. A notable example is polyphenylsulfide (PPS), a material with unique technical characteristics that make it valuable for many industrial applications.

Specific features:

Thermal properties

The PPS is known for its outstanding properties thermal, mechanical and electrical. Due to its superior heat resistance, this polymer can withstand high temperatures without deformation or degradation.
It is also a material flame resistant or as it is better defined self-extinguishing without special additives.

This feature makes it ideal for components used in high-temperature environments, such as motor parts, electrical equipment, and LED devices.

Chemical properties

In addition to thermal resistance, the PPS also offers considerable chemical resistance.

It is able to withstand various chemicals, including oils, fats, acids and bases. This property makes it suitable for use in corrosive environments, such as the chemical industry, where it is used to manufacture components that come into contact with aggressive fluids.

Mechanical properties

The "p p s" in particular thanks to the reinforcements of glass fiber and/or mineral fillers (e.g. PPSGF40), it boasts excellent mechanical properties, such as high tensile strength, stiffness e hardness.

These mechanical properties enable PPS to maintain its structural integrity even under mechanical stress. As a result, PPS is widely used in the production of lightweight but strong structural components, such as housings for electronic devices, parts for the automotive industry, and aerospace components.

Electrical properties

From the electrical point of view, PPS is an excellent insulator. Its low electrical conductivity and the resistance to electrical arcing make it an ideal choice for electronic applications, including connectors, device enclosures and components for the semiconductor industry.

In this context, Bear Plast has developed a deep understanding of the potential for pps polymer to combine and acquire characteristics suitable for a variety of industries.


The polyphenyl sulfide (PPS) is a high-performance polymer with a wide range of applications in a wide variety of commodity sectors. Its thermal, mechanical and electrical properties make it a versatile and reliable material for components requiring high temperature resistance, chemical resistance, structural integrity and electrical insulation.

Bear Plast, thanks to the knowledge gained from years in the field, is able to use "p p s" and any type of polymer to create innovative solutions tailored to the specific needs of each individual customer.
