PVC-U/C Rubber Gasket for Industry

Key Features

• EPDM material: excellent acid/alkali, ozone, and aging resistance.
• Elastic seal: fills flange face irregularities under compression for reliable sealing.
• Industrial-grade durability: suitable for chemical and water treatment corrosive environments.
• Full size range: fits standard PVC-U/C industrial flanges.

Manufacturing Process

Manufactured by compression molding or die-cutting. EPDM compound is vulcanized and formed with precise control of cross-sectional shape and dimensions.

Critical Process Parameters

• ID, OD, bolt hole positioning accuracy.
• Uniform thickness.
• Control of rubber hardness, tensile strength, and compression set.

Raw Material Characteristics

• Material: Ethylene Propylene Diene Monomer (EPDM), industrial-grade formulation.
• Properties: Resistant to acids, alkalis, ozone, and aging.
• Wide operating temperature range: -30°C to +120°C.
• Good elasticity and compression recovery.

Typical Applications

• Sealing for chemical piping flange connections.
• Flange interfaces in industrial water treatment equipment.
• Flange sealing in corrosive fluid transport systems.

Application Scenarios

• Sealing for industrial piping flange connections.
