Co-extruded Rubber Seals, Co-Extrusions, Co-Extruded EPDM Rubber Seals Manufacturers in China
The co-extrusion process allows for multiple hardness seals to be formed and bonded together in one piece construction. Co-extruded rubber seals, also known as dual durometer extrusions, allow you to have both sponge and dense materials in the same component. The dense material allows the components to create a strong connection to metal, while the softer material is generally used as a flexible seal. This combination gives you the best of both worlds: the strength of a clip section with the flexibility of a seal section
During co-extrusion, both materials are extruded at the same time. Co-extruded parts can be made with compatible rubbers or plastics. Various types of rubber and sponge rubber or rigid and flexible plastic materials can be combined into a single, extruded part. Of course, the materials selected must be chosen to best serve the needs of your application and your budget.
Advantages:
- Water resistant, and it can stand up to harsh weather conditions such as sleet and snow.
- Excellent resistance to abrasions and tears and ability to stand up to the degrading effects of weathering, ozone and UV ray exposure.
- Good electrical resistance. Its chemical properties make it especially suitable for electrical insulation and gaskets.
- It resists polar solvents, and not just water, but also acids, alkalies, and phosphate esters.
- It does a great job of withstanding steam and low and high temperatures
- It has a low compression set, so it won’t lose much resilience over prolonged pressure.
