EPDM Mat Granules

EPDM mat granules are high-performance elastic granular materials made from ethylene propylene diene monomer (EPDM) rubber, widely used in sports surfaces, playground safety mats, fitness paths, and recreational areas. Our EPDM granules have excellent property of weather resistance, maintaining stability under UV exposure, ozone attack, and extreme temperature variations over the long term. More importantly, 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 manufacturers in China and the world. We'd like to send free samples for you to test. Our EPDM granules support customization in multiple particle sizes and colors, including RAL color cards, Pantone color cards, and color matching based on customer samples, meeting the differentiated needs of various climate regions worldwide.

What Core Problems Can EPDM Granules Solve?

When purchasing EPDM granules, customers typically face several core concerns: How long will the color last? Will the granules become brittle or crack under extreme climates? Are the products environmentally safe? Is the supply stable? Our EPDM granules are specifically designed to address these needs.

First, for customers in hot and humid regions (such as the Middle East and Southeast Asia), ordinary rubber granules tend to fade, harden, or even decompose due to UV radiation and heat. Our peroxide-cured EPDM granules have a more stable molecular cross-linked structure, with excellent heat resistance and significantly improved color retention. For customers in cold regions (such as Northern Europe, Canada, and Russia), the saturated backbone structure of EPDM gives it outstanding low-temperature elasticity, remaining flexible even at minus 50 degrees Celsius, without becoming brittle from repeated freeze-thaw cycles. For rainy and humid regions, the non-polar nature of EPDM provides good resistance to water, acids, alkalis, and polar solvents. Long-term immersion in water will not cause performance degradation or mold growth.

In addition, many customers worry about the "toxic running track" issue. Our products solve this concern from the source: we do not use sulfur vulcanization systems, so no sulfuric acid substances are released under high temperatures and strong UV exposure — no odor, no pollution, meeting increasingly strict environmental regulations.

Applications and Advantages

The core applications of EPDM granules include: playground safety mats, rubber running tracks, infill granules for artificial turf, fitness trails, kindergarten flooring, anti-slip surfaces around swimming pools, multi-functional sports courts, and the production of prefabricated rubber rolls and tiles.

From a performance perspective, our EPDM granules offer the following key advantages: Weather Resistance — the chemically saturated backbone structure of EPDM provides excellent resistance to ozone, UV, oxygen, and temperature changes. Elasticity and Tensile Strength — the peroxide vulcanization system gives the product a tensile strength of 4-7 MPa, with elasticity and tensile strength improved by 2-3 times compared to traditional products. Service Life — improved molecular structure stability increases the performance retention rate by more than 5 times and extends service life by 3 times. Color Stability — high color consistency combined with excellent UV stability keeps granules vibrant even after long-term outdoor exposure. Environmental Safety — the sulfur-free formula ensures no harmful substances are decomposed at high temperatures, with a flame retardant rating of Grade 1. Processing Compatibility — low bulk density and strong angular three-dimensionality provide better coverage and application results when combined with polyurethane adhesives.

Durability Performance Across Different Climate Regions

Customers in different regions worldwide face significantly different climate challenges, making the adaptability advantages of EPDM granules even more prominent.

Tropical and Subtropical Regions (Middle East, Southeast Asia, South Asia, parts of Africa): Year-round high temperatures, strong UV, and frequent rainfall. Our peroxide-cured EPDM granules will not soften or deform at high temperatures, and UV stability ensures colors do not fade easily. Compared to sulfur-cured products, their heat aging resistance is more outstanding, significantly extending service life in continuous high-temperature environments.

Cold and Temperate Regions (Northern Europe, Canada, Russia, Northern China): Extreme winter cold and frequent freeze-thaw cycles. EPDM's glass transition temperature is as low as approximately minus 60 degrees Celsius, maintaining elasticity at low temperatures without becoming hard and brittle like ordinary rubber. Repeated freeze-thaw cycles will not damage the internal structure of the granules, with minimal performance degradation.

Arid and Desert Climates (Middle East, Australian Outback, Southwestern United States): Extreme heat, intense sunlight, and large day-night temperature differences. EPDM's heat resistance is further enhanced under the peroxide vulcanization system, maintaining good color stability and structural integrity under long-term exposure.

Rainy and Humid Regions (UK, Northern European coasts, tropical rainforest areas): Long-term high humidity environments. As a non-polar rubber, EPDM has excellent water resistance and will not experience performance decline or mold growth due to water absorption. Surfaces remain dry and safe even after long-term use.

Frequently Asked Questions (FAQ)

What is the difference between EPDM granules and ordinary rubber granules?

EPDM (ethylene propylene diene monomer) rubber has a fully saturated backbone structure, far superior to natural rubber, styrene-butadiene rubber (SBR), and other general-purpose rubbers in weather resistance, ozone resistance, UV resistance, and temperature resistance. Ordinary black rubber granules are mostly derived from recycled tires, with limited color options and possible heavy metal content. EPDM granules can be produced in multiple colors with controllable environmental performance.

Are your EPDM granules truly environmentally safe?

Yes. We use peroxide vulcanization technology, and our products contain no sulfur. This means that under high temperatures and strong UV exposure, the granules will not decompose to produce sulfides — no odor, no pollution, no harm to human body. This characteristic is particularly important for schools, kindergartens, and indoor sports facilities.

What colors can be customized?

We support RAL color card customization, Pantone color card customization, and color matching based on customer samples. Standard colors include red, green, blue, yellow, gray, orange, purple, etc. Color combinations can also be tailored to project requirements.

What particle sizes are available?

We offer standard particle sizes including 0.5-1.5mm, 1-3mm, 1-4mm, 2-4mm, and can also customize special specifications based on customer requirements. Different particle sizes are suitable for different applications: 0.5-1.5mm is commonly used for artificial turf infill and fine surfaces, 1-3mm is suitable for playground mats and track surfaces, and 2-4mm is suitable for elastic base layers.

Is durability guaranteed under different climate conditions?

EPDM's saturated backbone structure gives it excellent tolerance across all types of climates worldwide. Our peroxide vulcanization process further enhances heat aging resistance, oxidation resistance, and UV resistance, ensuring long-term performance stability in extreme heat, extreme cold, strong UV, and humid environments.

What is the minimum order quantity and delivery time?

We support flexible minimum order quantity policies that can be negotiated based on customer needs. Regular orders can be produced and shipped within a relatively short time after confirmation, with support for full container and less-than-container shipping.

Do you support OEM and private label?

Yes, we support OEM, ODM, and Private Label services. Packaging design and label customization can be carried out according to customer brand requirements.

How is the flame retardant performance of the granules?

Our EPDM granules have a flame retardant rating of Grade 1, suitable for indoor and public applications with fire safety requirements.
