EPDM Profile
Hard Rubber Sealing StripsBefore we discuss EPDM profiles it is very important to understand what is EPDM. EPDM is Ethylene Propylene Diene Monomer and is a type of elastomeric material. EPDM (Ethylene propylene diene monomer is a kind of synthetic rubber that is obtained by the process of copolymerisation of ethylene, propylene and a diene monomer in non-conjugated form. EPDM also contains ingredients like reinforcing carbon black, fillers, processing aids, antioxidants along with vulcanising ingredients. Some properties of EPDM rubber that makes them particularly useful as Extruded products include:
Parameters to Consider in EPDM Profiles
Following are some of the important parameters that needs to be considered before deciding on EPDM profiles. All these parameters need to be delicately balanced and followed strictly for having products with optimal characteristics:
EPDM Vs Thermoplastic Materials
EPDM profiles provide unlimited strength and elasticity. There is virtually no affect whatsoever in terms of shrinkage, melting, hardening or cracking over decades of use. The membrane retains its flexibility at temperatures ranging from -40º C to + 150º C.

Another high point of EPDM is that it is capable of absorbing thermal and structural movements during the course of linear elongation. This can be up to 300%. EPDM also displays multi axial elongation which exceeds 100%, at any given temperature. In a shift away from the thermoplastic materials EPDM shows no yield point. This means that even when EPDM, is deformed to extreme limits, it can get back to its original size, shape and thickness. Another high point over the thermoplastic materials is that due to the viscoelastic properties, EPDM can withstand virtually unlimited pressure load. All this qualities are lapped up by extruders while selecting EPDM profiles for manufacturing Extruded profiles. The following diagram elucidates the above mentioned properties:
Thermoplastic
Application of EPDM profiles
The EPDM profiles are used in numerous applications. Some of the important categories of application includes Automotive applications like Bus body building. Other categories include construction Industry, Marine Industry, Furniture edging etc. Let's take a look at the products now.
Extruded Rods and Cylinders: The right mix of EPDM and Neoprene
