Multi Layer Composite Valve Rubber Diaphragm EPDM PTFE Laminated Chemical Barrier Dual Hardness

Multi-Layer Composite Valve Rubber Diaphragm

Advanced multi-layer composite diaphragm featuring an EPDM base layer with PTFE lamination for superior chemical barrier properties. The dual-hardness design combines a flexible sealing zone with a rigid mounting area for optimal performance.

Key Features

• Construction: EPDM base + PTFE chemical barrier layer
• Dual Hardness: Soft sealing zone (55A) + rigid mounting zone (80A)
• Chemical Resistance: PTFE layer provides universal chemical compatibility on wetted side
• Temperature Range: -20°C to +130°C
• Flex Life: >1 million cycles with PTFE lamination
• Permeability: Ultra-low gas permeability for vacuum service
• Customization: Layer materials configurable per application

Applications

Chemical processing valves requiring universal chemical resistance, vacuum systems, high-purity gas handling, corrosive fluid control, and pharmaceutical processing.

Quality Assurance

Each diaphragm undergoes layer adhesion testing and dimensional inspection. ISO 9001:2015 certified manufacturing with full traceability.
