RAL 5010 EPDM Granules

RAL 5010 is a deep, saturated Gentian Blue that ranks among the more pigment-weathering-demanding colors in the EPDM colored granule spectrum. As a dedicated EPDM granule manufacturer, we use peroxide vulcanization rather than conventional sulfur vulcanization, ensuring that the granules will not decompose into sulfuric acid-type substances due to residual sulfur under prolonged UV exposure—eliminating odor, pollution, and human contact risks at the source. Our RAL 5010 EPDM granules maintain color saturation while delivering excellent UV stability and weathering durability, suitable for sports surfaces and recreational paving scenarios with strict requirements for color consistency and environmental standards. We offer free samples for your own testing and support full customization from particle size to packaging.

What Core Problems Do EPDM Granules Solve for Users?

When purchasing EPDM granules, what users truly care about is not the granules themselves, but whether the installed surface will fade, develop odors, chalk, or generate dust over three to five years or more—and whether maintenance costs will spiral out of control. RAL 5010, as a deep blue tone, is precisely the color that most readily exposes problems in inferior granules—products with low rubber content or sulfur vulcanization systems often show whitening, graying, or localized color variation in blue tones first after one or two summers of outdoor exposure.

Our peroxide-vulcanized EPDM granules address this risk at the molecular structure level. Because they contain no sulfur, they do not generate acidic decomposition products under high temperature and intense UV conditions, so no irritating odor occurs, and there is no potential skin irritation for those in contact. Meanwhile, the carbon-carbon bonds formed by peroxide crosslinking have higher bond energy and a more stable molecular network, giving the granules significantly better anti-aging performance and color retention than conventional vulcanization systems. For schools, kindergartens, public sports stadiums, and other venues with increasingly stringent environmental acceptance standards, this characteristic directly reduces the risk of rework caused by odor or hazardous substance test failures.

Application Scenarios and Performance Advantages

RAL 5010 EPDM granules cover the vast majority of venues requiring colored elastic surface layers:

Sports Surface Systems: track top layers, basketball courts, tennis courts, and colored anti-slip layers for multi-functional sports areas. Deep blue is often used for lane marking zones or venue boundary identification, with extremely high demands on color consistency and UV resistance.

Artificial Turf Infill Systems: As elastic infill granules for artificial turf, RAL 5010 can be combined with other colored granules to provide stable resilience and foot-feel support. Note that the rubber content of high-quality EPDM granules is the key indicator determining infill layer lifespan—low-rubber-content products tend to chalk and generate dust under long-term foot traffic and UV exposure.

Outdoor Leisure and Play Areas: Safety surfacing for children's playgrounds, park pathways, and colored top layers for community fitness areas. The high elasticity and flame retardancy (Class 1 flame retardant rating) of EPDM granules provide additional safety assurance for public spaces.

Pre-fabricated Mats and Rolls: As surface layer material for pre-fabricated rubber mats, providing color decoration and wear protection.

In terms of durability, the saturated hydrocarbon backbone structure of EPDM gives it intrinsic stability against ozone, oxygen, UV, and temperature extremes. Regarding different climatic conditions, our granules demonstrate differentiated adaptability: in the high-temperature, intense-UV environments of the Middle East and tropical regions, the peroxide vulcanization system combined with high-lightfast pigments effectively delays color degradation; in the rainy and humid markets of Northern Europe and Southeast Asia, the low-water-absorption dense structure prevents granules from accelerated aging due to repeated wet-dry cycles; in the severe winter cold of North America and Northeast Asia, granules maintain elasticity at low temperatures and will not become hard and brittle like some low-cost materials. This cross-climate stability directly translates into lower replacement frequency and whole-life-cycle cost advantages.

Frequently Asked Questions (FAQ)

How long will RAL 5010 color visibly fade outdoors?

Color retention depends on the combined effect of the pigment system and vulcanization process. Our RAL 5010 uses high-lightfast pigments combined with peroxide vulcanization, demonstrating color fastness far superior to conventional sulfur-vulcanized products in accelerated aging tests. Actual outdoor service life is affected by local UV intensity, installation thickness, and usage frequency. Under normal sports venue conditions, the color retention period typically reaches several years without visibly discernible significant fading. We can provide retained samples from the same batch for your subsequent comparative verification.

How can I determine whether the rubber content of EPDM granules meets standards?

Rubber content is the core indicator distinguishing high-quality from low-end EPDM granules. The industry-standard rubber content for premium products is around 20%; low-priced products often reduce costs by adding large amounts of calcium carbonate filler, resulting in chalking, dust generation, and color loss within a short period. A simple field test: rub a small amount of granules between your palms—if noticeable color powder remains on your palms or the granules crumble when pinched, it typically indicates insufficient rubber content or poor pigment bonding. We provide rubber content test data with every batch and welcome you to request samples for your own testing.

What particle size specifications do you support? Can RAL 5010 be customized to other particle sizes?

Standard supply particle sizes include 0.5-1.5mm, 1-3mm, 1-4mm, and 2-4mm, with customization of special size ranges available according to installation process requirements. RAL 5010 can be produced in all the above particle size specifications, with color consistency guaranteed within the same order. Recommended particle size selections differ for artificial turf infill versus plastic track top layers; our technical team can provide particle size matching recommendations based on your specific application scenario.

Is there a large price difference between peroxide-vulcanized and sulfur-vulcanized granules?

The raw material costs and process control requirements of peroxide vulcanization systems are higher than conventional sulfur vulcanization, so the unit price is typically somewhat higher. However, from a whole-life-cycle perspective, the significantly extended anti-aging lifespan and color retention period of peroxide-vulcanized EPDM granules mean lower maintenance and replacement frequency, making the overall cost more advantageous for projects pursuing long-term service benefits. We offer product lines for both processes, allowing you to choose flexibly based on project positioning and budget.

Do you provide custom blending of RAL 5010 with other colors?

Yes. RAL 5010 is often blended with light gray, white, or green granules in specific proportions for pattern formation or visual zoning. We support customer-provided color combination schemes or samples, producing mixed batches according to specified ratios while ensuring consistency of color proportions between batches.

What are the minimum order quantity and lead time?

Minimum order quantities are flexibly set based on particle size and packaging requirements, with both LCL and FCL shipments supported. Orders for standard colors and specifications can be produced and shipped within a short period after confirmation; custom color or special particle size orders require corresponding production scheduling lead time. Please confirm specific delivery times with our sales team—we will provide clear time milestones in our quotation.
