Ethylene Propylene Diene Monomer – EPDM

Mel Art and Industrial Rubber Company, due to years of experience and expertise in the field of Ethylene Propylene Diene Monomer or EPDM rubber compound formulation consultation and also having expert and experienced staff, is ready to provide Ethylene Propylene Diene Monomer rubber compound formulation consultation.

Ethylene Propylene DN Monomer Rubber (EPDM)

It is a type of compound rubber that has the properties of natural rubber and has a large amount of elasticity and resilience, so that it can return to its natural state. without any permanent deformation.

What are the goals of compounding?

Mixing tires or compounding ethylene propylene diene monomer generally pursues 3 main goals, which are as follows:

1- Controlling the rheological behavior of rubber

2- Improving the physical, mechanical and dynamic properties of rubber

3- controlling the cost of tires

 Measurable physical, mechanical and dynamic properties in nitrile rubber compound formulation

1. Hardship
2. Tensile strength
3. Percentage increase in length
4. pressure mana
5. heat resistance
6. Chemical resistance
7. Ozone resistance
8. Other tests

What is mastication in the rubber compounding process?

If we want to provide a definition of mastication, we can say that the term mastication is “putting the elastomer under tension to reduce the molecular mass and create viscosity (thickness) in the product with the aim of improving the mixing and quality of the ethylene propylene diene monomer compound.”
Mastication in the production of ethylene propylene diene monomer compounds can be done in two ways:

1- Physical mastication

2- Chemical mastication in compound formulation (use of peptizers)

A raw elastomer can never be used alone because the raw elastomer is not processable on its own and resists mechanical processes.

This resistance to processability is called Nerve, the higher the Nerve of a rubber, the more difficult the processability of that rubber will be.

Practically, Nerve means spending time and energy in rubber processing and this means more cost for processing in the field of producing ethylene propylene diene monomer or ethylene propylene diene monomer compound.

We try to reduce the Nerve of the rubber in different ways at the beginning of the work so that we can add the additives to the raw elastomer with more quantity and quality.

What is the elastomer in the formulation of ethylene propylene diene monomer compound?

Elastomer is actually a polymer that has great elasticity.

The name of elastomer consists of two parts “elasto” (derived from “elastic” and meaning elastic) and “mer” (derived from “polymer”).
