Weather-Resistant And Anti-Aging EPDM Granules

Weather-resistant and anti-aging EPDM granules are high-performance colored rubber granules made from EPDM (ethylene propylene diene monomer) rubber as the core raw material, produced through peroxide vulcanization technology, and specifically engineered for ground systems that are exposed to outdoor environments over the long term. The EPDM molecular backbone is a fully saturated hydrocarbon structure, a chemical feature that fundamentally enables the material to resist UV radiation, ozone, extreme temperatures, and rain erosion. Unlike conventional sulfur-vulcanized products, peroxide vulcanization forms stable carbon-carbon crosslinks between polymer chains, so the granules do not decompose into sulfuric acid substances under high temperature and strong UV exposure. They are therefore odorless, pollution-free, and safe for the human body. Whether in the continuous high-temperature exposure of the Middle East, the severe freeze-thaw cycles of Northern Europe, or the hot and humid rainy climate of Southeast Asia, this product maintains color stability and lasting elasticity. We sincerely invite global customers to request free samples to verify product performance through actual testing.

Our EPDM granules have excellent property of weather resistance....and more healthy because we use the method of peroxide sulfidation, there is no sulfur in our EPDM granules, hence It doesn't produce sulfides when exposed to sunlight, no pollution to environment, no odor and no harm to human body.

We are one of the highest-quality and most cost-effective EPDM granules in China and the world, we'd like to send free samples for you to test.

What Core Problems Do We Solve for Users?

Users who purchase EPDM granules typically face the following practical challenges, and weather-resistant and anti-aging EPDM granules are designed precisely to provide solutions to these pain points:

Fading and chalking. Ordinary colored rubber granules noticeably fade or even turn white after one or two years of use in areas with strong UV radiation, losing their original visual quality. The saturated backbone structure of EPDM, combined with a high-quality UV stabilization system, enables color fastness to reach high industry standards, and light color series also deliver excellent weather resistance.

Odor and environmental compliance. Granules produced through sulfur vulcanization may release sulfide odors under high-temperature conditions, affecting scenarios sensitive to air quality such as children's activity areas and indoor venues. The peroxide vulcanization system eliminates sulfur components at the source, and the product is odorless with no release of harmful substances.

Performance degradation at high and low temperatures. In regions with drastic temperature differences, inferior granules are prone to low-temperature embrittlement or high-temperature softening and deformation. EPDM granules have undergone systematic high- and low-temperature verification and maintain stable mechanical properties across a wide temperature range.

Short service life and frequent replacement. The carbon-carbon bonds formed by peroxide vulcanization have higher bond energy than sulfur crosslinks, significantly improving the anti-aging performance of the granules and extending service life by several times, reducing long-term maintenance and replacement costs.

Applications and Advantages

Weather-resistant and anti-aging EPDM granules are widely used in various outdoor and indoor sports and leisure ground systems, including plastic track surfaces, artificial turf infill granules, safety mats for kindergartens and children's playgrounds, fitness trails, tennis courts and multi-functional sports fields, anti-slip surfaces around swimming pools,commercial landscape paving and Artificial Turf.

Core advantages are reflected in the following dimensions:

Excellent weather resistance stability. The saturated structure of the EPDM backbone gives it natural resistance to UV radiation, ozone, and acid rain. For different climate regions, product performance remains stable: in the hot and arid Middle East, granules are not prone to softening and deformation, and colors remain vibrant; in cold and snowy North America and Northern Europe, elasticity is maintained under low-temperature conditions without embrittlement; in the hot and humid rainy Southeast Asia and South America, hydrolysis resistance is excellent, and the product does not degrade due to long-term moisture. Through an optimized formulation system, the product demonstrates color retention far exceeding standard requirements in accelerated aging tests.

Safe and environmentally friendly. Peroxide vulcanization technology ensures the product contains no sulfur components, does not decompose into sulfuric acid under high temperature and strong UV exposure, and is odorless, pollution-free, and harmless to the human body. The product meets strict environmental indicator requirements and is suitable for application scenarios sensitive to air quality.

Outstanding mechanical properties. Tensile strength can reach 4-7 MPa, with excellent elongation at break, and elasticity and tensile capacity are significantly improved compared with conventional products. Moderate elasticity not only provides good energy feedback for sports but also effectively absorbs impact force, reducing the risk of sports injuries.

Long-lasting color. High-quality pigments and an antioxidant system are used, resulting in vivid colors that resist fading. RAL color card, Pantone color card, and sample-based customization are supported to meet the color design requirements of different projects.

Frequently Asked Questions

What is the core difference between peroxide-vulcanized EPDM granules and sulfur-vulcanized granules?

Peroxide vulcanization connects polymer molecular chains through carbon-carbon bonds, which have high bond energy and a stable structure; sulfur vulcanization connects them through sulfur bridges. The former is significantly superior to the latter in heat aging resistance, UV resistance, and color stability, and carries no risk of sulfide release.

How do your products perform in extremely hot regions such as the Middle East?

EPDM itself has excellent heat resistance, and peroxide vulcanization further improves thermal stability. In strong UV and high-temperature environments such as the Middle East, granules are not prone to softening and do not fade, and with an appropriate PU binder system, ground performance can be maintained over the long term.

Will granules become brittle and crack when used in cold regions?

No. The glass transition temperature of EPDM is relatively low, and the product has been verified for low-temperature performance. It remains elastic at -20°C to -40°C without embrittlement. It is suitable for cold markets such as Northern Europe, Canada, and Northern China.

Do you support customized colors and particle sizes?

Yes. We provide RAL color card customization, Pantone color card customization, customer sample-based customization, and multiple color combination solutions. Conventional particle sizes include 0.5-1.5mm, 1-3mm, 1-4mm, and 2-4mm, and special specifications can be customized on demand.

What is the minimum order quantity? Can you provide free samples?

The minimum order quantity is flexible and varies according to specifications and colors. We are happy to provide free samples to global customers for testing and verification.

Is the product environmentally friendly? Are there any test certifications?

The product adopts a sulfur-free peroxide vulcanization process, contains no sulfides, and meets environmental requirements. Corresponding test reports and compliance documents can be provided according to the customer's target market.
