Open-cell vs closed-cell sponge rubber

Posted by LMI Custom Mixing on May 10, 2018 8:53:48 AM

A cellular, or sponge rubber compound, is made up of raw materials found in most standard rubber compounds such as a base polymer, fillers and plasticizers as well as processing, antidegradant and curing additives. However, it also includes a blowing agent that creates a specific type of cellular structure within the rubber matrix during the curing process.

Advantages of EPDM compounds in outdoor applications

Posted by LMI Custom Mixing on Dec 11, 2017 2:00:00 PM

Ethylene-Propylene-Diene-Monomer (EPDM) is a versatile polymer with outstanding ozone, weathering and aging resistance, making it ideal for use in outdoor applications.

EPDM polymers have good processability as well as good chemical and electrical properties. They exhibit very good physical properties even at very high filler loadings. These properties benefit a wide range of customers who use engineered elastomers in a broad range of applications.
