Gray High-Strength Ultra-High Molecular Weight PPS Solid Resin Raw Material

Product Overview
Gray High-Strength Ultra-High Molecular Weight PPS (Polyphenylene Sulfide) Solid Resin is a premium-grade engineering thermoplastic in its pure, unmodified form. Characterized by its exceptionally high molecular weight, this raw material delivers superior mechanical integrity, thermal stability, and chemical resistance, providing a robust foundation for compounding, extrusion, or high-performance molding applications.

Key Material Properties

• Ultra-High Molecular Weight & Strength: Offers exceptional tensile strength, impact resistance, and long-term durability for demanding structural applications.

• Outstanding Thermal Resistance: Maintains properties at continuous high temperatures, surpassing many standard PPS grades in heat aging performance.

• Excellent Chemical & Hydrolytic Stability: Highly resistant to a wide range of aggressive chemicals, solvents, and steam, ensuring reliability in harsh environments.

• Inherent Flame Retardancy (UL 94 V-0): Provides excellent fire safety characteristics without relying on additives.

• Low Moisture Absorption & High Purity: As a base resin, it ensures consistent performance and serves as an ideal starting material for specialized compounds.

Common Applications

• High-Performance Compounding: Base resin for creating custom PPS compounds (e.g., GF40, CF-reinforced) with enhanced properties.

• Demanding Industrial Parts: Used in manufacturing high-strength gears, bearings, pump components, and valve seats.

• Electrical & Automotive: Critical for components requiring the highest thermal and chemical endurance, such as specialty insulators and under-hood parts.

• Film & Fiber Applications: Suitable for advanced applications like high-temperature filtration or capacitor films.

Material Comparison: UHMW PPS vs. PEI as a Base Resin
While PEI (Polyetherimide) is an excellent high-temperature resin, Ultra-High Molecular Weight PPS offers superior inherent chemical resistance, a higher continuous use temperature, lower moisture absorption, and better flow characteristics at high temperatures—making it a more durable and cost-effective choice for the most challenging thermal-mechanical-chemical environments.
