EPDM Rubber Mouldings
EPDM Rubber Mouldings
At Advanced Seals & Gaskets, our expertise lies in crafting customized rubber moulded components using a diverse range of rubber materials, EPDM included. The creation of these rubber mouldings necessitates the use of specialized machinery and processes, namely compression, transfer, or injection moulding. This is primarily because they demand unique shapes, intricate profiles, ribbed textures, and sometimes even features like lips and curved edges. Such intricate requirements make it impractical to produce EPDM rubber mouldings by simply pressing them from sheet materials.
EPDM rubber mouldings manifest in various forms, serving distinct functions. They take the shape of feet, buffers, seals, or O-rings, each carefully engineered to deliver precise protective, leak prevention, and aesthetic qualities. Every EPDM rubber moulding is bespoke, constructed based on meticulously precise customer-provided dimensions, samples, or drawings. The corresponding tool or moulded cavity is created with scrupulous attention to detail, ensuring precision in every aspect.
EPDM rubber mouldings find their calling in outdoor applications, where exposure to diverse elements like chemicals, water, UV radiation, weathering, and ozone is commonplace. The exceptional resilience of EPDM rubber renders it the perfect choice for the rigors of such demanding environmental conditions.
What are EPDM Rubber Mouldings?
The process of rubber moulding is transformative for raw EPDM rubber material, shaping it into tailored products through one of three key methods: compression, transfer, or injection moulding. In certain scenarios, such as when crafting O-rings, the cord is initially extruded and subsequently manually joined to form the circular shape.
EPDM rubber mouldings come in diverse forms, which may be either solid or hollow, contingent on the intended applications. The manufacturing process ensures the uniform and precise formation of each part, ensuring consistent quality. The versatility of EPDM mouldings is nearly boundless, making them suitable for a broad array of industries.
Some instances of EPDM rubber mouldings encompass rubber sleeves, rubber bellows (coverings), rubber feet, buffers, and various components designed for sports equipment. The adaptability and versatility of EPDM rubber render it an invaluable material for a myriad of applications.

Why use EPDM Rubber Mouldings?
Rubber mouldings are the perfect solution for customers in need of custom profiles, specifically designed for unique applications. The moulding process guarantees consistent, identical products, making it a vital component for high-volume production.
Extrusion combines the advantages of a precisely fitting moulded rubber profile with the outstanding properties of EPDM rubber. The EPDM rubber's temperature range, spanning from -30°C to +110°C, coupled with its resistance to UV rays, ozone, and weather, renders it an ideal choice for applications both indoors and outdoors.
EPDM rubber mouldings are frequently employed across a wide spectrum of industries, serving a myriad of sealing applications. They exhibit remarkable versatility, being suitable for sleeves, feet, bellows, and edge trims. With EPDM rubber available in numerous hardnesses and grades, it becomes possible to create highly customized profiles tailored to specific needs.

- Variety of Grades
- Resistance to Fine Particles
- Can be made to bespoke designs
- Created an air and water tight seal
Processes
There are three primary processes involved in EPDM rubber moulding:
Injection Moulding:
- In injection moulding, raw EPDM material is heated and injected into a mould cavity under controlled pressure and heat, causing the material to cure and create the moulded product.
Compression Moulding:
- Compression moulding employs pre-heated steel moulds where raw material is poured and the mould halves are closed together. This process is effective for custom moulding but may be time-consuming for high-volume production.
Transfer Moulding:
- Transfer moulding is the most intricate process. Raw material is loaded into a transfer pot, heated, and pressurized by a plunger, forcing the melted rubber through a channel into the mould cavity. Once cured, the mould is opened to retrieve the formed component.
Different Grades
Advanced Seals & Gaskets collaborates with a multitude of material manufacturers and suppliers, offering customers a wide array of EPDM rubber moulding options. Various grades include:
FDA Grades:
- Food quality EPDM comes in blue and white, perfect for food and pharmaceutical applications. Resistant to animal and vegetable oils, it's non-toxic and functions within a temperature range of -25°C to +140°C.
WRAS Approved EPDM Rubber Sheeting:
- Ideal for potable water applications, meeting BS 6920-1:2000 and BS 6920-1:2014 standards. It's resistant to weathering, ozone, aging, and chemicals, with a working temperature from -40°C to +120°C.
Peroxide Cured EPDM:
- Vulcanized with peroxide instead of sulphur, offering enhanced temperature resistance, heat resistance, and improved oil and chemical resistance. Suited for demanding applications, such as nuclear facilities.
