Techtron® HPV PPS
- Chemical Family
- Polyphenylene Sulfide (PPS)
Techtron® HPV PPS is a high-performance polymer that combines the excellent chemical and corrosion resistance of Polyphenylene Sulfide (PPS) with the added wear resistance and strength of glass fiber reinforcement and internal lubrication. This compression-molded material is designed to excel in demanding environments and applications where wear resistance and dimensional stability are required.Key features:Superior wear resistance: internally lubricated and glass fiber-reinforced, allowing it to withstand high loads and minimize wear and tearOutstanding chemical and hydrolysis resistance: suitable for use in harsh environments and chemicalsExcellent dimensional stability: minimal moisture absorption and low coefficient of linear thermal expansion, making it easy to maintain tight tolerancesGreat electrical insulating and dielectric propertiesLow coefficient of friction and inherent low flammabilityGlass fiber reinforced: increased strength and stiffness, ideal for wear componentsFood grade availableBenefits:Improved performance and durability of components in demanding environmentsIncreased resistance to chemicals, corrosion, and wearEnhanced precision and dimensional stabilityImproved electrical insulation and dielectric propertiesReduced friction and lower flammability riskMore cost-effective than advanced engineering plastics for certain applicationsApplications:Wear components such as bushings and bearings, CIP wash down parts, and pump, valve, and compressor applications in the aerospace, food processing, and oil and gas industries.Industrial equipment such as industrial drying and food processing ovens (bearings, rollers, etc.)Chemical process equipment (pump-, valve & compressor components)Electrical insulating systemsCost-effective alternative to advanced engineering plastics in certain applicationsTechtron® HPV is a versatile and reliable material that can help improve the performance and longevity of your products. It's available in a range of shapes and sizes, including food grade, making it easy to incorporate into your designs.

- Engineering Notes
All Mitsubishi Chemical Advanced Materials-EPP's PPS products offer dimensional stability and strength at moderate temperatures. They are rated for continuous service to 425°F (220°C), but strength and stiffness vary based on temperature and grade. Unreinforced Techtron® PPS is generally not recommended for wear applications. Products like Torlon® PAI or Ketron® PEEK are better selections for high temperature wear applications. When designing with compression molded grades, it is important to note its relatively low elongation and impact strength.
