Celanese PPS (Tecaona)
Overview
Polyphenylene Sulfide (PPS) Ticona, produced by Celanese, is a high-performance thermoplastic renowned for its exceptional thermal and chemical resistance. It belongs to the family of engineering plastics and is widely used in demanding industrial applications. PPS is available in various grades, including reinforced versions with glass or carbon fibers for enhanced mechanical properties. Its ability to withstand high temperatures (up to 220–240 °C continuously) and aggressive chemicals makes it a preferred material for automotive, electrical, and aerospace industries.
Physical and Chemical Properties
PPS exhibits remarkable stability under extreme conditions. Its melting point ranges between 280–290 °C, and it maintains mechanical integrity even at elevated temperatures. The material is inherently flame-retardant (UL94 V-0 rating) and resists degradation from acids, bases, and organic solvents. With a density of 1.34–1.36 g/cm³, PPS is lightweight yet robust. It has low moisture absorption (<0.05%), ensuring dimensional stability in humid environments. Electrical properties, such as high dielectric strength and insulation resistance, make it ideal for electronic components.
Main Applications
PPS Ticona is extensively used in automotive systems, including fuel system components, sensors, and under-the-hood parts, due to its resistance to gasoline and oils. In electronics, it serves as housings for connectors, switches, and circuit boards. Industrial applications include pump parts, valve seats, and chemical processing equipment where corrosion resistance is critical. The aerospace sector utilizes PPS for lightweight, high-strength components. Reinforced grades are common in structural applications requiring rigidity and thermal stability.
Safety and Storage
PPS is generally safe for handling but requires standard industrial precautions. Dust generated during processing should be controlled with proper ventilation or respirators. Skin contact with molten PPS must be avoided to prevent burns. Storage recommendations include keeping the material in sealed containers to prevent moisture absorption. Although PPS has excellent hydrolytic stability, prolonged exposure to humidity may affect processing performance. Store away from direct sunlight and extreme temperatures to maintain polymer integrity.
B2B Procurement Guide
When sourcing PPS Ticona, clarify the required grade (e.g., unfilled, 40% glass-filled) and certifications (e.g., FDA compliance for food-contact applications). Technical datasheets should be reviewed for property metrics like tensile strength and thermal deflection temperature. Suppliers often offer pellets or molded parts. For bulk procurement, inquire about lead times and batch consistency. Pricing varies based on volume, with larger orders typically discounted. Partner with distributors or manufacturers providing material traceability and post-sales support.
