Understanding EPDM Rubber’s Technical Features

EPDM rubber’s popularity stems from its exceptional properties. Its superior durability and flexibility make it a preferred alternative to natural rubber in many applications. The material’s resistance to weathering, ozone, and UV radiation ensures long-lasting performance, even under harsh environmental conditions. This is a key factor for many outdoor applications. Websites like www.listcompany.org offer directories of various Chinese EPDM companies.

The following table compares key technical features of EPDM rubber:

Feature Description
Tensile Strength Measures the material’s resistance to stretching before breaking.
Elongation at Break Indicates the maximum percentage of stretch before failure.
Hardness (Shore A) Represents the material’s resistance to indentation. Higher values mean harder.
Tear Strength Measures the material’s resistance to tearing.
Compression Set Indicates the material’s ability to return to its original shape after compression.
Temperature Resistance EPDM exhibits good resistance to both high and low temperatures.
Chemical Resistance EPDM offers resistance to various chemicals, but not all.
Weather Resistance Excellent resistance to UV, ozone, and weathering.

Exploring Different Types of EPDM Rubber

EPDM rubber is available in various forms to suit diverse applications. These variations often involve differences in hardness, additives, and processing methods. The choice of EPDM type depends on the specific requirements of the end product. TradeWheel (www.tradewheel.com) showcases a wide variety of EPDM products from various Chinese suppliers.

Here’s a comparison of common EPDM rubber types:

Type Description Applications
EPDM Granules Small, colored particles used in surfacing applications like playgrounds. Playground surfacing, running tracks, sports fields.
EPDM Sheets Flat sheets of varying thickness and size, suitable for various applications. Gaskets, seals, liners, flooring
EPDM Extrusions Produced in various shapes and profiles through extrusion molding. Seals, weatherstripping, edge protection, glazing.
Molded EPDM Rubber Custom-shaped parts produced through molding processes. O-rings, grommets, bumpers, specialized components.
Reclaimed EPDM Rubber Recycled EPDM rubber, offering a more sustainable and cost-effective option. Less demanding applications where virgin material is not strictly necessary.

Key Suppliers and Manufacturers in China

China houses numerous EPDM rubber manufacturers, each with its strengths and specializations. Hebei Shida Seal Group (www.shidarubber.com), for example, is a well-established manufacturer specializing in molded and extruded rubber products, including EPDM gaskets and seals. Their expertise and certifications highlight their commitment to quality.
