Product Description

Polyurethane Abrasion Resistant Valve Rubber Diaphragm

High-performance polyurethane (PU) diaphragm engineered for extreme abrasion environments in mining, mineral processing, and slurry handling. Delivers 3-5 times longer service life compared to conventional rubber diaphragms in abrasive media.

Key Features

  • Material: Premium Polyurethane (PU) elastomer
  • Abrasion Resistance: DIN abrasion <30 mm³ (exceptional)
  • Hardness: 90 ±5 Shore A
  • Tensile Strength: ≥35 MPa
  • Tear Strength: ≥80 N/mm
  • Temperature Range: -20°C to +80°C
  • Oil Resistance: Good resistance to mineral oils
  • Elasticity: Excellent rebound and fatigue resistance

Applications

Mining slurry valves, mineral processing equipment, sand and gravel handling, concrete pumping systems, dredging equipment, and any high-wear abrasive media valve application.

Quality Assurance

DIN abrasion testing per batch with full dimensional inspection. ISO 9001:2015 certified manufacturing.
