Ethylene, propylene, and diene monomers are the components of EPDM (ethylene propylene diene monomer), a synthetic rubber. Its single bond, chemically-saturated molecular structure gives it a very strong resistance to the elements. This is due to the fact that, unlike double-bonded rubbers, its molecular structure cannot be disrupted by ozone or UV rays. Read More…

More EPDM Rubber Molding Companies
Synthetic rubber includes EPDM rubber. It has a wide range of uses because of its extraordinary durability and flexibility, including in cars (where it is used for cooling system hoses, window and door seals, and more), cold rooms, non-slip deck and playground coatings, and many other places.
Simply said, while synthetic rubber (EPDM) maintains flexibility and can endure temperature changes for decades, pure rubber becomes brittle with temperature changes.
EPDM Molding Process
Closing the mold and pouring heated EPDM into the exposed mold cavity are the first steps in the procedure. For injection, a preset amount of EPDM is divided into smaller strips and put through a screw.
Vents allow displaced air to escape when the mold fills in order to avoid air bubbles and other flaws. Rubber compounds like EPDM are heated and subjected to much more pressure per square inch of cavity surface than plastics, which is one of the main differences between injection molding rubber and plastic.
High pressure and high temperature help plasticize the parts to cure the compound and plasticize the individual pieces, whereas plastic is cooled under less pressure. The length of time required for each cycle of parts to fully cure varies depending on the particular design. Once complete, the mold opens and the parts are manually removed or ejected so that the process can start over.
Advantages of EPDM Molding
- It provides exceptional resistance to UV, ozone, weathering, aging, and different chemicals.
- It is excellent for outdoor use.
- EPDM offers stability in temperatures that are extremely hot and low.
- It withstands steam and water.
- It provides low conductivity of electricity.
- EPDM has the ability to be used across a wide range of industries and applications.
- Its longevity and toughness are ideal for constant use.
- EPDM is cheaper than silicone.
- Eco-friendly: While white EPDM roofs are less common, they are still an option and can reflect UV rays and even help cut down on energy expenses. They work well with solar panel arrays and rooftop plants. Due to its lightweight nature, this material can adapt to any shape or style of roof while still offering the same benefits. Additionally, very little time or resources are needed to create this material, and it is completely recyclable.
Applications of EPDM Rubber
- Automotive: Thanks to its adaptability, toughness, and weatherability, EPDM is used in this application the most frequently. It can be found in wire and cable harnesses, brake systems, seals, weather stripping, and sealant for automobiles. Additionally, it is combined with other materials to create automotive bumpers, rub strips, and fender extensions.
- Industrial: EPDM is used in industrial applications because of its toughness, flexibility, waterproofing, and electrical-insulating qualities. Electrical insulators, connections for wire and cable, and parts like O-rings, hoses, and gaskets for water systems are all made of EPDM. Additionally, it may be found in belts, grommets, diaphragms, and accumulator bladders.
- Construction: EPDM is widely used in the roofing industry because of its qualities as an insulator, weatherproof material, and waterproof material. The sealant, expansion joints, garage door seals, pool and tank liners, and waterproof coating for bitumen roofs are additional uses for it. Even the roofs of RVs utilize it.
- HVAC: Due to its weatherability and temperature endurance, EPDM is used in this business as insulation, tubing, gaskets, seals, and grommets.
- Pond liners: Whether it's a pond, a water feature, or a stream, water is ideal for fostering a serene, natural atmosphere in outdoor settings. Doing so is really simple with EPDM pond liners! The pre-assembled pond liners are not only quick and simple to install, but they also have a 30-year lifespan. Additionally, EPDM is bleach resistant and toxic-free, making it ideal for fish, plants, birds, and other nearby species.
- Water tank liners: Because EPDM's molecules are so closely packed together, it is highly challenging for water and vapor to move through it. This makes it perfect for use in biogas and water storage tank linings. It also helps that it doesn't shrink or crack over time.
Choosing the Proper EPDM Manufacturer
To make sure you have the most positive outcome when purchasing EPDM from an EPDM manufacturer, it is important to compare at least 4 companies using our list of EPDM manufacturers. Each EPDM manufacturer has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the manufacturer for more information or request a quote. Review each EPDM company website using our proprietary website previewer to get an idea of what each company specializes in, and then use our simple RFQ form to contact multiple EPDM companies with the same form.
