Comparing EPDM with Other Rubber Types

Choosing the right material is crucial for the success of various applications, and understanding how EPDM Rubber compares to other commonly used elastomers is essential. Let’s explore the comparisons between EPDM Rubber and Neoprene Rubber, Nitrile Rubber, Viton Rubber, Natural Rubber and Silicone Rubber

  • EPDM Rubber vs. Neoprene Rubber – While both offer good weather resistance properties, EPDM Rubber excels in UV and ozone resistance. Neoprene is known for its oil resistance however, making it suitable for different applications, including automotive seals and gaskets. 
  • EPDM Rubber vs. Nitrile Rubber – EPDM Rubber outshines in weather resistance and UV stability, whereas Nitrile Rubber offers superior oil and fuel resistance properties. Applications in automotive and aerospace fuel systems typically favour Nitrile Rubber, while EPDM Rubber finds use in roofing and outdoor applications. 
  • EPDM Rubber vs. Viton Rubber – Viton Rubber offers superior chemical resistance, especially in harsh environments. However, EPDM Rubber is significantly more cost-effective and is more versatile across a wide range of applications. 
  • EPDM Rubber vs. Natural Rubber – Natural Rubber is renowned for its elasticity and versatility, but lacks UV and weather resistance. EPDM Rubber, on the other hand, excels in UV stability, making it the go-to choice for outdoor applications. 
  • EPDM Rubber vs. Silicone Rubber – EPDM is more cost-effective and offers unique properties, however Silicone excels in high temperature resistance, making it the preferred option for applications involving extreme heat, such as in cooking or baking equipment. 

Grades of EPDM Rubber 

EPDM Rubber comes in various grades, each designed to meet specific requirements across different applications. Understanding these distinctions between grades is crucial for selecting the right EPDM rubber for your intended purpose. Let’s delve into three notable grades: Commercial Grade EPDM Rubber, WRAS Approved EPDM Rubber and Expanded EPDM/Neoprene Closed-Cell Sponge Rubber. 

Commercial Grade (CQ) EPDM Rubber 

Commercial Grade EPDM Rubber serves as the foundational choice for many different professional industry applications. Recognised for its combination of durability, flexibility and cost-effectiveness, it’s often the go-to elastomer for projects requiring a reliable, all-purpose material. 

CQ Grade EPDM Rubber is ideal for scenarios where high-performance specifications aren’t paramount, the material excels in common applications like roofing membranes, gaskets and straightforward weatherstripping. Its balanced properties make it an optimal choice for various general purpose applications. 

WRAS Approved EPDM Rubber:

WRAS Approved EPDM standards with its specialised certification involving usage with portable water for human consumption. Adhering strictly to the Water Regulations Advisory Scheme (WRAS), it ensures the highest standards of safety and quality in water-related contexts. 

WRAS APproved EPDM is crucial in water and plumbing systems, where maintaining water quality and adhering to stringent regulatory standards is non-negotiable. ITs also the material of choice for applications demanding strict adherence to water safety protocols, including applications where water intended for human consumption is involved. 

Expanded EPDM/Neoprene Closed-Cell Sponge Rubber:

Combining EPDM with Neoprene in a closed-cell structure, this grade elevates its insulation properties. The closed cell structure of the Expanded EPDM/Neoprene sponge prevents water absorption, making it particularly valuable in applications where moisture resistance is paramount. 

Expanded EPDM/Neoprene is frequently used for applications requiring both effective insulation and resilience against environmental element.s For example in HVAC systems and outdoor gasketing, the material excels in scenarios that demand robust protection against moisture and external stresses.
