Mitsui EPT: A Polymer Solution for Heat & Chemical Resistance

Mitsui EPTTM is a special type of synthetic rubber produced using a unique olefinic polymerization technology. Keeping pace with the demand for products crafted using advanced technology, Mitsui Chemicals India has consistently been delivering innovative products, and EPT is one of them.

Ethylene-Propylene-Terpolymer, or EPT, as it is widely known, is brilliantly versatile and can be put to use in varied applications. This blog takes you through its characteristic features and helps you to understand it better. 


Remarkable properties of Mitsui EPTTM

Eco-friendly polymer

Here are some of the features of EPT that make it suitable for multiple use cases:

1. Weather and ozone resistance

  • The chemical structure of EPT (Saturated Hydrocarbon Chain) distinguishes it from other rubbers and thus provides outstanding weather and ozone resistance. Even with continuous exposure to UV radiation, the polymer structure is not degraded.
  • Due to this, it can be combined with other diene rubbers to improve weather and ozone resistance.

2. Temperature resistance

The Saturated Hydrocarbon Chain of EPT enables excellent heat resistance. It can be efficiently used in higher temperatures for long durations. 

3. Insulation

EPT can be used as an insulation material. It also has wonderful corona and tracking resistance. These features make EPT better than other rubbers, such as SBR, NR, and IIR. 

4. Chemical Resistance

The chemical resistance of EPT is also outstanding. It is resistant to higher polarity organic solvents such as alcohol, ketone, glycol, inorganic salt, water solution, acid, and alkali.

Applications of Mitsui EPT

Due to the exceptional features of EPT, it is used in a variety of applications. Some of them are:


Automotive applications

  • Weather resistance, processability, temperature resistance, chemical resistance, and insulation properties make EPT the best choice for use in automotive applications.
  • Some automotive components manufactured using EPT are window seals, glass run channels, weatherstrip sponges, radiator hoses, lamp seals, electrical wire sheathing, grommets, and gaskets and many more.


Industrial applications

  • The various features of EPT make it suitable for use in various industrial applications, such as Wire and Cable, roofing, pond liners, lining sheets and construction.
  • It is used to manufacture conveyor belts, grommets, o-rings, gaskets, roofing applications, wire and cable sheathing, heat insulator sponges, and tubing.
