Polystone M Flametech AST is an ultra-high molecular weight polyethylene (UHMWPE) grade specifically engineered with flame-retardant and anti-static additives. This formulation ensures compliance with FRAS (Flame Resistant Anti-Static) and MDG3608 standards, making it suitable for use in hazardous underground coal mining environments. The material delivers a balance of safety and performance through its inherent low friction (coefficient of 0.15), high chemical resistance, and a tensile strength of 22 MPa.
Dotmar supplies this compliant UHMWPE in sheet format, supported by machining and fabrication expertise to meet exact project requirements. By choosing Polystone M Flametech AST from Dotmar, Australian industry gains access to a locally stocked, safety-certified material that minimises downtime through reliable wear performance.
Key Features
- FRAS and MDG3608 approved for underground coal mining
- Coefficient of friction 0.15 for low wear and sliding ease
- Operating temperature range from -250 °C to 80 °C
- Tensile strength of 22 MPa
- High resistance to chemicals
- Available in sheet format for machining and fabrication
Polystone M Flametech AST is commonly employed in underground coal mines for wear plates, belt scrapers, conveyor rollers, impact pads, and other components where fire resistance and anti-static behaviour are essential. Its low friction and high wear resistance also make it suitable for chute and hopper linings in general materials handling, particularly where dust or gas hazards exist.
