RAL 1015 EPDM Granules

RAL 1015 EPDM granules are ternary ethylene-propylene-diene monomer rubber granules produced in the standard RAL Light Ivory color. They are designed for sports surfaces and leisure areas that require a soft visual texture and long-term weather resistance. RAL 1015 belongs to the lighter shades of the RAL Classic color card, with a warm, pale tone that is suitable for outdoor applications where reduced glare reflection and a comfortable spatial atmosphere are desired. These granules are manufactured using peroxide vulcanization technology and contain no sulfur. Under high temperatures and intense ultraviolet exposure, they do not decompose into sulfides, so they produce no irritating odor, no environmental pollution, and no harm to the human body. The granules offer excellent resistance to ozone, oxidation, and UV aging, maintaining color stability and physical performance under diverse climatic conditions worldwide. We provide custom production services for RAL 1015 and other RAL and Pantone colors to customers around the world, support multiple particle size specifications and packaging options, and can send free samples for your testing and verification.

What Core Problems Can EPDM Granules Solve for You

For operators or contractors of sports venues and leisure facilities, performance degradation, color fading, and environmental compliance of ground materials are among the most common pain points. EPDM granules provide systematic solutions to these problems at the material level.

Performance degradation after long-term outdoor exposure. Ordinary rubber granules tend to harden, crack, or powder under the combined effects of ultraviolet radiation, ozone, and temperature cycling. The saturated hydrocarbon backbone of EPDM gives it natural resistance to these environmental factors. After peroxide vulcanization, the molecular crosslinking network becomes more stable, and the service life can be extended several times compared with traditional vulcanization systems.

Insufficient color durability. Light-colored ground materials are especially prone to yellowing or fading under UV exposure. RAL 1015 granules use high-performance pigments and anti-UV additives during production. Combined with the more stable molecular structure achieved through peroxide vulcanization, they can maintain color vibrancy under long-term sunlight exposure, reducing the need for premature renovation caused by fading.

Environmental compliance and human safety. More and more countries have introduced strict requirements for volatile organic compounds, polycyclic aromatic hydrocarbons, and heavy metal content in infill granules for sports surfaces. EPDM granules themselves contain no sulfur, and the peroxide vulcanization process further avoids the risk of residual harmful substances from the vulcanization process. The product does not release acidic decomposition products at high temperatures, is odorless and non-toxic, and is suitable for children's activity areas and school venues.

Construction compatibility. The low bulk density and angular three-dimensional structure of EPDM granules give them better coating and bonding strength when mixed with polyurethane adhesives, helping to form a uniform, dense elastic surface layer and reducing the risk of granule detachment and delamination during construction.

Applications and Advantages of EPDM Granules

EPDM granules cover a wide range of ground systems, from professional sports surfaces to everyday leisure spaces.

In sports venues, EPDM granules are widely used in elastic surface layers for plastic running tracks, basketball courts, tennis courts, badminton courts, and multi-purpose sports courts. Their high elasticity and shock absorption help reduce impact on joints during exercise. Light-colored granules such as RAL 1015 are particularly suitable for outdoor venues where surface temperature rise needs to be controlled—colored granules absorb less solar radiation than black tire rubber granules, so surface heating is more moderate.

In artificial turf systems, EPDM granules are used as infill material laid between the grass filaments to support the grass blades, provide foot cushioning, and adjust court elasticity. Granules of 1-3 mm and 2-4 mm are common infill specifications for turf.

In children's playgrounds and outdoor leisure areas, EPDM granules are used in safety mats and buffer layers around play equipment. The elasticity and non-toxic properties of the material make it a common choice for ground materials in children's activity spaces. The soft tone of RAL 1015 also matches the visual design needs of children's venues.

In fitness trails, community leisure areas, and landscape surfaces, light-colored EPDM granules can reduce the visual pressure of large ground areas while providing a comfortable walking experience.

The core advantage of EPDM granules compared with other ground infill materials lies in the balance of comprehensive performance: they simultaneously offer excellent weather resistance, color stability, elasticity, and environmental safety. Compared with SBR tire recycling granules, EPDM contains no tire-derived pollutants such as polycyclic aromatic hydrocarbons, and offers a richer choice of colors. Compared with TPE/TPV materials, fully crosslinked EPDM granules have more reliable dimensional stability and anti-aging performance in long-term use.

Durability Under Different Global Climatic Conditions

The molecular structure of EPDM determines its good adaptability in a variety of climatic environments.

High-temperature and strong UV regions (Middle East, Southeast Asia, Africa, Australia). Peroxide-vulcanized EPDM granules are not prone to softening, sticking, or rapid color fading under continuous high temperatures and intense sunlight. The saturated nature of the EPDM backbone gives it intrinsic resistance to ultraviolet radiation and ozone, and it does not degrade rapidly through oxidation like unsaturated rubbers. Light-colored RAL 1015 granules can also reduce heat absorption to a certain extent.

Cold regions with large temperature differences (Northern Europe, North America, Russia, Canada). EPDM maintains elasticity at low temperatures and has a low brittle point, making it suitable for outdoor surfaces that experience repeated freeze-thaw cycles. The material has good tolerance to frost and de-icing salts and will not become brittle and crack due to low temperatures.

Rainy and high-humidity regions (United Kingdom, Japan, parts of South America). EPDM granules have low water absorption and are not prone to hydrolysis or mildew when exposed to rain and humid environments over long periods. The three-dimensional angular shape of the granules helps surface drainage and reduces the risk of water accumulation. The material's tolerance to diluted acids and alkalis also makes it suitable for areas with frequent acid rain.

Arid and dusty regions. The oxidation and aging resistance of EPDM keeps it from surface powdering in dry, dusty environments, and both color and elasticity retention remain high.

Frequently Asked Questions (FAQ)

What exactly is the color of RAL 1015?

RAL 1015 is "Light Ivory" in the RAL Classic color card. It belongs to the light beige family with a slight warm tone. Its visual effect under outdoor sunlight is soft and natural, and it does not produce harsh glare like pure white.

What is the difference between EPDM granules and SBR granules?

EPDM is made from ternary ethylene-propylene-diene monomer rubber, with customizable colors and excellent UV and weather resistance. It does not contain substances such as polycyclic aromatic hydrocarbons commonly found in tire recycling materials. SBR granules usually come from recycled waste tires, have lower cost, but offer limited color options, and their environmental compliance faces stricter scrutiny in different markets. For children's venues, schools, and projects with color requirements, EPDM is the more suitable choice.

How long is the service life of EPDM granules?

Under normal outdoor use conditions, the expected service life of peroxide-vulcanized EPDM granules can reach 8-15 years, depending on climate intensity, frequency of use, and maintenance conditions. The molecular structural stability brought by peroxide crosslinking gives the product a significantly better performance retention rate after long-term exposure than traditional vulcanization systems.

Can you customize colors other than RAL 1015?

Yes. We support full RAL color card customization, Pantone color matching, and customer sample-based color customization. We can match colors according to the sample or color code you provide, confirm after proofing, and then mass-produce to ensure color consistency.
