In the world of industrial piping and fluid handling, the integrity of every connection is paramount. Flange gaskets may be small components, but they play a critical role in ensuring system safety, efficiency, and longevity. As a leading manufacturer, we specialize in producing high-performance gaskets designed to meet the most demanding applications. This article delves into two of our most versatile materials: FKM (Fluorocarbon Elastomer) and EPDM (Ethylene Propylene Diene Monomer), guiding you to the optimal choice for your specific needs.
FKM, commonly known by the brand name Viton®, is a premium fluorocarbon elastomer renowned for its exceptional performance under extreme conditions.
Key Properties & Advantages:
Superior Chemical Resistance: FKM offers excellent resistance to a wide range of chemicals, including oils, fuels, acids, aromatic hydrocarbons, and halogenated fluids. This makes it indispensable in chemical processing, petrochemical, and pharmaceutical industries.
High-Temperature Stability: Our FKM gaskets maintain their sealing integrity in continuous service temperatures up to 200°C (392°F) and even higher for short periods, outperforming many standard elastomers.
Excellent Compression Set Resistance: They resist permanent deformation under constant compression, ensuring a reliable, long-lasting seal that minimizes maintenance and downtime.
Low Gas Permeability: FKM provides an exceptional barrier against gas diffusion, which is crucial for vacuum systems and applications involving volatile gases.
Ideal Applications for FKM Gaskets:
Chemical processing and injection systems
Oil and gas refineries
Automotive fuel handling systems
Pharmaceutical and semiconductor manufacturing
High-temperature hydraulic and lubrication systems
EPDM is a versatile and cost-effective rubber material celebrated for its outstanding resistance to weathering and polar substances.
Key Properties & Advantages:
Excellent Weather and Ozone Resistance: EPDM is highly resistant to degradation from sunlight, ozone, and extreme weather conditions, making it the perfect choice for outdoor applications and cooling systems.
Superior Steam and Hot Water Resistance: It performs exceptionally well with hot water and steam, far surpassing the capabilities of FKM in these mediums. This is a key differentiator for many users.
Compatibility with Polar Media: EPDM is compatible with a wide range of polar substances, including ketones, alkalis, Skydrol® fire-resistant hydraulic fluids, and many dilute acids and chemicals.
Wide Temperature Range: Our EPDM gaskets are effective in a broad temperature range, typically from -40°C to 150°C (-40°F to 302°F).
Ideal Applications for EPDM Gaskets:
Hot and cold water systems (potable water, cooling water)
Low-pressure steam applications
HVAC and refrigeration systems
Food and beverage processing (using FDA-compliant grades)
Pulp and paper industry, and power generation cooling systems
