Types of EPDM and Their Uses
Commercial Grade EPDM
Commercial grade EPDM is the most commonly used type of EPDM rubber. It is ideal for general applications such as roofing membranes, seals, and gaskets. Its cost-effectiveness and durability make it a popular choice in construction and automotive industries.
WRAS Approved EPDM
This type of EPDM is specifically certified for use in drinking water systems. It meets stringent regulations ensuring it is safe for potable water applications. Use WRAS approved EPDM for plumbing, gaskets, and seals that come in contact with drinking water.
Expanded EPDM/Neoprene
Expanded EPDM is particularly useful for insulation and moisture protection applications. Its closed-cell structure allows it to resist water absorption effectively, making it suitable for HVAC systems and other moisture-sensitive environments.
High-Performance EPDM
High-performance EPDM is designed for applications that face extreme conditions, including high temperatures and harsh chemicals. This variant is often used in automotive and industrial applications where enhanced flexibility and heat resistance are crucial.
Care Tips for EPDM Material
-
Cleaning: Regularly clean EPDM surfaces with a mild detergent and water to remove dirt and debris. Avoid harsh chemicals that can degrade the material.
-
Storage: Store EPDM products in a cool, dry place away from direct sunlight. This prevents UV degradation and extends the material’s lifespan.
-
Inspection: Periodically inspect EPDM seals, gaskets, and membranes for wear and tear. Replace damaged sections promptly to maintain performance.
-
Temperature Management: Avoid exposing EPDM to extreme temperatures beyond its rated range. This can lead to cracking or deformation.
-
Moisture Control: Ensure that EPDM products are installed correctly to prevent moisture accumulation, which can lead to mold and mildew.
Choosing EPDM for Different Applications
Automotive Use
When selecting EPDM for automotive applications, consider the following:
– Environmental Exposure: Choose EPDM with high UV and ozone resistance for weatherstripping and seals.
– Temperature Range: Ensure the EPDM can withstand both high and low temperatures typical in automotive environments.
– Chemical Resistance: Assess exposure to fluids and choose EPDM that can resist oils and other automotive chemicals.
Construction Use
In construction, EPDM is primarily used for roofing and waterproofing:
– Roofing Membranes: Opt for commercial grade or high-performance EPDM for roofing applications due to their durability and weather resistance.
– Seals and Gaskets: Use WRAS approved EPDM for any applications involving drinking water or plumbing systems.
Industrial Applications
For industrial uses, consider:
– Chemical Resistance: Ensure the EPDM can handle exposure to acids, alkalis, and solvents.
– Temperature Range: Select high-performance EPDM for extreme temperature environments.
Practical Tips for Using EPDM
- Installation: Ensure proper installation techniques are followed. Misalignment can lead to leaks and reduced effectiveness.
- Adhesives: When bonding EPDM to other materials, use adhesives specifically designed for rubber to ensure a strong bond.
- Avoid Oils: Keep EPDM away from petroleum-based products to prevent deterioration.
