Wet Pour EPDM Granules

Wet pour EPDM granules are an ethylene propylene diene monomer rubber granule material specifically designed for in-situ poured elastic flooring systems. They are typically mixed with polyurethane binder in a predetermined ratio and troweled in place to form a seamless, porous, elastic surface layer. As a professional EPDM granule manufacturer, we focus exclusively on granule production and customization, without involvement in installation. This allows us to dedicate all our efforts to formulation optimization, color control, and particle size precision, providing global buyers with stable and reliable raw materials.

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 EPDM Granules Solve for You

As a buyer or end user, when selecting EPDM granules, your primary concerns often go beyond price alone. What matters most is whether the material can maintain its performance over long-term use, whether it is genuinely safe and environmentally friendly, and whether the color will remain stable against weathering. Wet pour EPDM granules address these concerns on several levels:

Solving the problem of odor and harmful substance release under high-temperature exposure. EPDM granules produced with traditional sulfur vulcanization systems may decompose and release sulfides under intense UV radiation and high temperatures, producing unpleasant odors and potential health risks. We use peroxide vulcanization technology, and our EPDM granules contain no sulfur. This eliminates the formation of sulfuric compounds at the source. Even after prolonged exposure in hot climates, no irritating odor or harmful emissions are produced.

Solving the problem of color fading and aging. EPDM rubber itself offers outstanding resistance to oxidation, ozone, and weathering. Its resistance to UV, acid rain, and ozone is significantly superior to many alternative materials. Combined with the higher crosslink density achieved through peroxide vulcanization, the color retention and anti-aging performance of the granules are further enhanced, maintaining the original color for many years.

Solving durability differences across different climate conditions. Temperature ranges, rainfall levels, and sunlight intensity vary enormously across different regions of the world. EPDM granules have a wide applicable temperature range. They will not become brittle or crack in extremely cold regions, nor will they soften and degrade in hot and humid environments. Their molecular structure provides natural resistance to moisture penetration and rain erosion, making them suitable for climate zones ranging from the long winters of Northern Europe to the scorching summers of the Middle East.

Main Application Scenarios for Wet Pour EPDM Granules

The application scope of wet pour EPDM granules covers virtually all outdoor activity surfaces that require elasticity, safety, and aesthetics:

Children's playgrounds and kindergarten areas. This is the most typical application for wet pour EPDM. After mixing with binder, the granules form a soft, shock-absorbing surface that effectively absorbs impact when children fall, reducing the risk of injury. The rounded edges and low bulk density of the granules make them comfortable to walk on, and they will not easily scratch the skin even when children run barefoot.

School and community sports areas. These include running tracks, basketball courts, tennis courts, volleyball courts, and multi-functional sports zones. The EPDM surface provides stable friction and moderate elasticity, helping athletes perform at their best while reducing fatigue and injury to joints and muscles.

Artificial turf infill systems. As functional infill granules for artificial turf, EPDM's elasticity and shape allow it to sit firmly between the grass filaments, providing a footfeel and cushioning close to natural grass, while not being easily displaced by cleats.

Pool surrounds and water parks. Wet environments demand extremely high slip resistance. Wet pour EPDM surfaces offer excellent anti-slip properties, maintaining friction even when wet. The surface is non-porous and does not harbor bacteria, making it easy to clean and maintain.

Park walkways and landscape areas. Compared to asphalt or concrete, EPDM granule surfaces are softer and more sound-absorbing. With a wide range of color options, they can be integrated into landscape design, enhancing both the aesthetic appeal and the walking experience of public spaces.

Core Advantages of Wet Pour EPDM Granules

Safe and environmentally friendly, suitable for sensitive groups. The sulfur-free formulation means the product will not produce sulfide contamination throughout its lifecycle. The material is non-toxic, odorless, and free from harmful heavy metals, meeting the strict environmental requirements of children's activity areas.

Both elasticity and tensile strength. Peroxide vulcanization gives EPDM a more stable molecular crosslink structure. The elasticity and tensile strength of the product reach 4-7 MPa, which is 2-3 times that of ordinary products. This means the granules are less likely to crack or powderize under long-term foot traffic and climate exposure.

Color consistency and customization freedom. We support color customization according to RAL and Pantone color cards, and also accept customer sample matching. Automated production lines and strict batch management ensure consistency of the same color across different orders, so large-scale projects will not suffer from color difference issues.

Global climate adaptability. Whether it is the intense sunlight of equatorial regions, the salt spray of coastal areas, or the freeze-thaw cycles of cold zones, the weather resistance of EPDM granules has been verified through practical applications. For areas with particularly strong UV radiation, using them together with an appropriate UV-stable polyurethane binder can further extend color life.

Frequently Asked Questions

What particle sizes do you offer?

Standard particle sizes include 0.5-1.5mm, 1-3mm, 1-4mm, and 2-4mm. Other special specifications can also be customized according to your installation process and surface design requirements. Generally speaking, finer particle sizes are commonly used for the aesthetic surface layer, while coarser particle sizes are suitable for the elastic base layer.

What is the difference between peroxide vulcanization and sulfur vulcanization, and why does it matter?

Sulfur vulcanization is a traditional process with lower cost, but the product may release sulfides under high temperatures and UV exposure. Peroxide vulcanization does not introduce sulfur elements, and the crosslink structure is more stable. The anti-aging performance, color fastness, and environmental performance of the product are significantly improved, making it especially suitable for venues with high requirements for odor and safety.

Can your granules adapt to the climate of our country?

EPDM's temperature resistance range covers extremely cold to extremely hot environments, and it also has good resistance to rain and humidity. Whether your project is located in the hot and dry regions of the Middle East, the humid and rainy areas of Southeast Asia, or the low-temperature freeze-thaw zones of Northern Europe, our granules can maintain stable physical properties.

Do you support color customization and OEM?

Yes. We can produce according to RAL or Pantone color numbers, and also accept customer color samples for matching. OEM, ODM, and Private Label can all be discussed. Everything from packaging design to brand labeling can be executed according to your requirements.

What is the minimum order quantity and delivery lead time?

The minimum order quantity is flexible and can be negotiated based on your trial order needs. Delivery lead time for standard specifications and colors is usually relatively short. Custom colors and special particle sizes require a certain production scheduling period. We support both full container and less-than-container shipping, and can arrange fast delivery according to order conditions.

Do you provide samples?

Yes. We are willing to send free samples to interested customers for testing and evaluation. You only need to bear the reasonable freight cost.
