Ethylene propylene diene terpolymer, or EPDM for short, is a durable material made to withstand the toughest conditions. It can handle high temperatures and abrasive chemicals. Even though it's a tough material, that doesn't mean it has to be tough to work with. Our EPDM products are cleaner, easier to work with and enable efficient manufacturing. EPDM is a synthetic elastomer produced as a copolymer of ethylene and propylene, with small amounts of a pendant diene (double bonds) in order to cross link the material. The actual abbreviation EPDM conforms to the ASTM nomenclature guidelines as describing an Ethylene Propylene Diene PolyMethylene main chain elastomer.
Rubber Tubing What Is It? How Is It Made? Types, Materials
At its core, the EPDM extrusion process involves feeding raw EPDM rubber into the extruder, where it undergoes a transformative journey. The rubber is heated, softened, and forced through a specialized die that imparts the desired shape and dimensions to the profile. An extrusion die is a precise and specific tool made by cutting an opening through a blank of steel. The shape of the opening will match the finished rubber cross section desired for an extruded part. Once in place, the rubber material will be forced through this die via the pressure that builds up from the revolving screw of the extruder. Idealized EPDM polymer, red = ethylene-derived; blue = propylene-derived; black = ethylidene norbornene-derived. EPDM rubber (ethylene propylene diene monomer rubber) is a type of synthetic rubber that is used in many applications. Dienes used in the manufacture of EPDM rubbers are ethylidene norbornene (ENB), dicyclopentadiene (DCPD), and vinyl norbornene (VNB). 4-8% of these monomers are. Many low molecular The manufacture of an extruded weight ingredients like process dense profile broadly involves three aids and curatives at low concen-steps: compound mixing; extrusion trations can have high volatility, and shaping; and curing. which can cause porosity.
What is Metal Extrusion, types, and Manufacturing Process
The process EPDM rubber production from polymer-grade (PG) propylene and ethylene comprises three major sections: (1) polymerization; (2) purification; and (3) finishing (Figure 2). FIGURE 2. The diagram shows the polymerization process for making EPDM rubber Polymerization. Go to: Abstract The compounding of waste EPDM from postindustrial scrap with polypropylene (PP) is a possible way to manufacture thermoplastic elastomers to solve a significant environmental problem. Modeling the flow of ethylene propylene diene monomer (EPDM) through a Garvey die was achieved by employing the latest cloud computer technology commercially available at a modest cost. The description of the stress-strain behavior for EPDM was done using the Otswald-de Waele model. Extrusion is one of the most useful processes for making long rubber product profiles. The profile deforms while extruding due to swelling based on the geometry of the die, thermal and rheological properties of the material, and predominantly on the thermal and rheological boundary conditions.
Custom EPDM Extrusion Genesis Rubber Inc.
The manufacturing process of EPDM rubber involves three stages; Synthesis, Extrusion or Molding, and Finalizing. During the synthesis stage, ethylene, propylene and butadiene are combined to. CFD elastomer extrusion analyses have been mainly used to study the die-swell effect but, issues related to temperature control are poorly described [15-17]. Temperature control in the extrusion process of polymer materials is very important to provide better product quality and reduce energy consumption.

Deoflow AP and Deoflow Z--processing additives for EPDM extrusion compounds In general, when mixing and producing EPDM profiles, the processing additives significantly contribute to the viability of these processes and also to the surface finish of the resulting product. EPDM is used as a cheaper alternative to silicone rubber for parts that will have a lot of outdoor or moisture exposure, or for electrical insulation. However, it can also be used as roofing or liners. It's mainly used in four industries: Automotive. This is EPDM's most common application, thanks to its flexibility, resiliency, and.
