EPDM Tubing, Profiles & Elastomers

Ethylene propylene diene monomer (EPDM) is a synthetic rubber used to make a variety of common and versatile products, including rubber tubing. EPDM tubing resists heat, chemical, ozone, abrasion, and weather, making it a popular choice for use in many industries.

EPDM Properties

Understanding the properties of a given material is essential during the selection process. Here are some of the general properties of EPDM:

  •       Common names. EPDM is most commonly referred to by its chemical name ethylene propylene diene monomer, or by the acronym EPDM. Some of the common brand names for the gum polymer include Dutral®, Nordel®, and Vistalon®.
  •       Temperature range. EPDM can safely handle operating temperatures down to -20°F, and becomes brittle around -40°F. The high end of EPDM’s operating temperature range is approximately 300°F.
  •       Strength. EPDM features a tensile range between 500–2500 psi, which gives it excellent tear resistance compared to many other rubbers.
  •       Hardness. EPDM has a Shore A hardness between 30 and 90 depending on the specific material grade.
  •       Environmental/Chemical Performance. EPDM is broadly used because of its expansive spectrum of performance under difficult conditions. It resists UV radiation, ozone, many chemicals, abrasion, and tearing. However, it does have poor resistances to oil and solvents.

Difference Between EPDM and Silicone Rubber 

Silicone and EPDM are both used for rubber tubing, but the properties of the two materials vary. Knowing the differences is essential to ensure selection of the best rubber tubing for a particular use case.

EPDM has a polymer structure that makes it well equipped to withstand many environmental factors, such as UV and ozone exposure. EPDM tubing is cost competitive with silicone rubber and also features a higher tear strength. The primary limitation to EPDM rubber is its operational temperature range. EPDM tubing typically can’t handle temperatures much higher than 300°F or lower than -30℉. EPDM is also prone to swelling if exposed continuously to oil. 

Silicone rubber is an inorganic polymer composed of silicon, hydrogen, carbon, and oxygen. Silicone also withstands environmental factors well but offers a much broader operating temperature range. Silicone rubber can operate in temperatures up to 446°F. Where EPDM has higher tear strength, silicone offers better elasticity and remains elastic even in cryogenic temperatures down to -76°F.

EPDM Tubing Applications

EPDM’s applications vary across many industries, but here are some examples of common use cases:

  1. HVAC. HVAC systems rely on EPDM tubing for pressure switch tubing and drain tubes, among others.
  2. Automotive. EPDM tubing is often used in vehicles as heating and cooling hoses, washer fluid tubing, within emissions systems, and in hydraulic systems.
  3. Industrial. Industrial facilities commonly use EPDM rubber tubing as radiator and hydraulic hoses on machinery and equipment. Chemical manufacturers, in particular, benefit from EPDM tubing for its innate resistance to many chemistries. 
  4. Nuclear/Biological/Chemical Warfare (NBC). The military has increasingly turned to EPDM rubber for use in various NBC protective and decontamination equipment thanks to its ability to resist harsh cleaning agents after use.
