Beneficial properties of Ethylene Propylene Diene Monomer (EPDM) and Ethylene Propylene Rubber (EPR) are outstanding resistance to heat, ozone and weather. They show excellent resistance to hot and cold water, glycol, steam and polar chemicals like ketones and excellent electrical insulating properties.

EPDM and EPR show satisfactory compatibility with fireproof hydraulic fluids and alkalis.

*EPDM rubber is used in vibration dampening components, seals, glass-run channels, radiators, garden and appliance hoses, tubing, automotive and appliance seals, belts, electrical insulation. It is also used for roofing membranes, geomembranes, rubber mechanical goods and many other applications.

LMI offers a variety of both dense and sponge compounding options for the most sophisticated extrusion processes.



LMI offers options in both dense and cellular rubber for injection, compression, and injection molding processes.


Sponge Compounds 

LMI’s history and experience in the development and mixing of sponge compounds has made sponge one of our core product lines. Success in sponge requires excellent control over incoming raw materials, precise weighment of formulation additives, and incredible control throughout the entire mixing process. LMI offers a wide array sponge solutions for both continuous extrusion and molding processes.


Design and Development 

LMI offers a wide range of design and development support. An experienced support team is ready to provide assistance in compound optimization and design for many technical applications. LMI features a fully-equipped lab mixer for creating small, prototype batches. Test compounds can also be evaluated on a pilot Liquid Cure Medium (LCM).
