RAL 5015 EPDM Granules

RAL 5015 (Sky Blue) EPDM granules are color rubber granules refined from EPDM rubber, strictly following the RAL color standard to deliver a pure, bright sky blue tone. Produced with peroxide vulcanization technology as the core process, this product contains no sulfur, so it will not decompose sulfides under high temperature or intense UV exposure—fundamentally eliminating odor, pollution, and health hazards. Our EPDM granules combine high elasticity, high tensile strength, and excellent weather resistance, making them suitable for sports surfaces, playgrounds, and landscaping in all climate conditions worldwide. We are a leading professional EPDM granule manufacturer in China, dedicated to providing global customers with high-quality, cost-effective, customized products.

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 Needs Do EPDM Granules Solve for Users

For buyers and end users, the core demands behind choosing RAL 5015 EPDM granules usually revolve around the following key issues:

Color durability challenges. One of the biggest challenges for outdoor surfacing materials is UV-induced fading. If RAL 5015 sky blue fades, it seriously affects the appearance of the venue and brand image. Thanks to the molecular structural stability provided by our peroxide vulcanization system, our EPDM granules remain vibrant in color and resist discoloration even under long-term sunlight exposure.

Climate adaptability challenges. Climate conditions vary dramatically across countries and regions—the scorching heat of the Middle East, the freezing cold of Northern Europe, and the persistent high humidity and rainfall of Southeast Asia all impose strict requirements on material durability. The EPDM molecular structure itself offers excellent resistance to ozone, UV, and high/low temperatures, maintaining stable performance from -50°C to high-temperature environments.

Environmental and safety compliance. More and more projects have explicit restrictions on material odor and harmful substance release. The sulfur-free formula eliminates the possibility of hydrogen sulfide and other odorous gases from the source, posing no health risk to installers or users.

Customization matching needs. Designers and owners often need to precisely match specific color codes (such as RAL 5015) or brand visual systems, while also requiring particle sizes that match venue functions. We support full-spectrum color customization from RAL to Pantone, as well as flexible supply of multiple particle size specifications.

Applications and Advantages of EPDM Granules

Main Application Areas

RAL 5015 sky blue EPDM granules are widely used in scenarios with high requirements for color accuracy and durability:

- Sports surfaces: Indoor and outdoor tennis courts, basketball courts, badminton courts, and running track surfaces. The 0.5-1.5mm particle size is suitable for standard indoor tennis court surfacing, while 1-3mm and 1-4mm are suitable for outdoor courts and track systems.

- Children's playgrounds: Wet-pour safety mats and playground equipment buffer zones. The high elasticity and impact absorption of EPDM provide effective protection for children.

- Artificial grass infill: Used as elastic infill granules for artificial turf, providing athletic performance and foot feel.

- Landscaping and leisure areas: Pool surrounds, walkways, courtyard paving, and more.

Core Performance Advantages

Differentiated value from peroxide vulcanization technology. Compared with traditional sulfur vulcanization systems, peroxide vulcanization gives EPDM a more stable molecular crosslinking structure, bringing multiple performance improvements. The product contains no sulfur, so it will not decompose sulfuric acid-type substances under high temperature or intense UV exposure—no odor, no pollution, no harm to human body. Molecular structural stability extends service life by more than 3 times; elasticity and tensile strength increase by 2-3 times, reaching 4-7 MPa; performance retention improves by more than 5 times.

Outstanding weather resistance and aging resistance. EPDM has a highly saturated molecular backbone, providing natural resistance to UV, ozone, and thermo-oxidative aging. Research on the aging mechanisms of EPDM granules for plastic running tracks shows that aging resistance strongly depends on the synergistic effect of the plasticizer system and the vulcanization system, and rational formula design is the key to improving durability. Our peroxide vulcanization system is precisely the engineering application of this principle.

Global climate adaptability. EPDM granules demonstrate reliable durability across different climate zones: in hot regions such as the Middle East and the tropics, heat resistance ensures the granules do not soften or deform, and the sky blue color resists fading under intense sunlight; in cold regions such as Northern Europe and frigid zones, elasticity is maintained at low temperatures without embrittlement or cracking; in rainy and humid regions, EPDM offers good resistance to water, frost agents, and dilute acids and alkalis.

High color consistency. Strict batch quality control ensures that the RAL 5015 color code remains highly consistent across different orders, meeting the stringent requirements for color uniformity in large-area surfacing.

Safe and environmentally friendly. Flame retardant rating reaches Class 1. Low bulk density and strong angular three-dimensional appearance combine functionality with visual texture. The product is 100% recyclable and meets increasingly strict environmental requirements.

FAQ

What is the difference between RAL 5015 EPDM granules and ordinary blue granules?

RAL 5015 is "Sky Blue" in the German RAL color standard, with clearly defined color values. We strictly follow this standard for color matching and production, ensuring color accuracy and batch consistency. Ordinary blue granules often lack a standard color reference, making visible color differences between batches more likely.

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

Sulfur vulcanization is a traditional process. Sulfur-vulcanized rubber has good physical properties, but relatively weaker aging resistance and compression set resistance. The carbon-carbon crosslinks formed by peroxide vulcanization are more stable than the polysulfide bonds of sulfur vulcanization, so heat resistance, aging resistance, and compression set resistance are significantly improved. The most intuitive difference is: our granules contain no sulfur, so they will not release hydrogen sulfide-type odorous gases under high temperature or UV exposure.

How long can the product last in extreme high or low temperature environments?

EPDM has a wide tolerance range for high and low temperatures. Laboratory data show that properly formulated EPDM materials can withstand temperatures below -50°C without losing elasticity. In practical applications, surface temperatures in the Middle East can exceed 70°C in summer, while Northern European winters can drop to -30°C. Our granules perform stably in both types of extreme environments. The expected outdoor service life under normal use conditions is 6-10 years.

Can you provide a color board or sample of RAL 5015?

Yes. We provide free samples to global customers for testing and color confirmation. Simply let us know your specific application and required particle size, and we will arrange shipment.

What particle size specifications do you support?

We support multiple standard particle sizes including 0.5-1.5mm, 1-3mm, 1-4mm, and 2-4mm, and can also customize special specifications according to your installation process or design requirements. Different particle sizes suit different scenarios: finer granules are used for topcoat spraying or indoor venues, while coarser granules are used for base layers or areas requiring greater elasticity.
