Peroxide Cured Low Compression Set Valve Rubber Diaphragm 15 Percent Elastic Recovery EPDM

Peroxide Cured Low Compression Set Valve Rubber Diaphragm

Advanced peroxide-cured EPDM diaphragm engineered for continuous pressure applications where minimal permanent deformation is critical. Less than 15% compression set ensures long-term sealing reliability without frequent maintenance.

Key Features

• Material: EPDM compound, peroxide cured for superior crosslink stability
• Compression Set: <15% at 100°C for 72 hours (ASTM D395 Method B)
• Elastic Recovery: Outstanding rebound after prolonged compression
• Temperature Range: -40°C to +130°C
• Hardness: 65 ±5 Shore A
• Curing: Peroxide cure system for clean, bloom-free surface
• Chemical Resistance: Good resistance to water, steam, and mild chemicals

Applications

Continuously pressurized control valves, pressure regulating systems, HVAC controls, water distribution systems, and automated process valves requiring long maintenance intervals.

Quality Assurance

Compression set testing per ASTM D395 on every batch. ISO 9001:2015 certified facility.
