Top 10 EPDM Rubber Products Manufacturers and Suppliers in China
On the lookout for some of the best EPDM Rubber Products Manufacturers and Suppliers in China? This guide delves into the world of EPDM rubber, exploring its properties, types, and key manufacturers in China. We’ll examine technical specifications and compare different EPDM variations, helping you make informed decisions.
Understanding EPDM Rubber
EPDM, or ethylene propylene diene monomer, is a synthetic rubber known for its exceptional durability and flexibility. Unlike natural rubber, EPDM exhibits superior resistance to ozone, UV radiation, and many chemicals. This makes it ideal for outdoor applications and environments with harsh conditions. Companies like those listed on www.listcompany.org showcase the breadth of EPDM applications in China.
Technical Features of EPDM Rubber
EPDM’s technical features vary depending on the specific formulation and additives used. However, some key characteristics consistently stand out. The following table compares some important technical properties:
| Property | Typical Range/Value | Units | Notes |
|---|---|---|---|
| Tensile Strength | 7-15 | MPa | Varies with formulation and additives. |
| Elongation at Break | 300-500 | % | Indicates flexibility and resistance to tearing. |
| Hardness (Shore A) | 40-90 | Shore A | Affects the rubber’s stiffness and resilience. |
| Density | 1.1-1.5 | g/cm³ | Influences weight and overall product properties. |
| Temperature Resistance | -40°C to +150°C | °C | The operating temperature range can be extended with specific formulations. |
Types of EPDM Rubber
EPDM rubber comes in various forms, each suited for specific applications. The differences often lie in the additives, processing methods, and final product form. Consider these variations:
| Type | Description | Applications | Advantages | Disadvantages |
|---|---|---|---|---|
| EPDM Granules | Small, colored rubber particles used as infill for sports surfaces. | Playgrounds, running tracks, athletic fields | Versatile, durable, shock-absorbing | Requires binding agent for installation |
| EPDM Rubber Sheets | Flat sheets of EPDM rubber, available in various thicknesses and colors. | Gaskets, seals, waterproof membranes, flooring | Easy to cut and shape, good weather resistance | Can be less flexible than other forms |
| EPDM Tubing/Hose | Hollow tubes of EPDM rubber, used for conveying fluids or gases. | Automotive applications (coolant hoses), industrial applications | Chemical resistance, flexibility, temperature resistance | Limited size range compared to other EPDM products |
| Molded EPDM Rubber Parts | Custom-shaped EPDM parts manufactured using molding techniques. | Automotive, industrial, and specialized applications requiring specific shapes | High precision, complex designs possible | Higher manufacturing cost compared to extruded products |
| EPDM Foam Rubber | EPDM rubber with added air bubbles, offering cushioning and insulation. | Weatherstripping, seals, gaskets | Lightweight, shock absorption, good thermal insulation | Lower strength compared to solid EPDM |
