2-4mm Green EPDM Granules

2-4mm green EPDM granules are a type of EPDM (ethylene propylene diene monomer) colored rubber granule, specifically engineered for sports surfaces, artificial turf infill, and recreational flooring systems. As a professional EPDM granule manufacturer, we understand that granule quality directly determines the performance of the finished surface. Our EPDM granules have excellent property of weather resistance. Manufactured using peroxide vulcanization technology, our green EPDM granules contain no sulfur. They do not decompose into sulfuric acid under high temperatures or intense UV exposure, producing no odor, no pollution, and no harm to the 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. The 2-4mm specification is a mainstream particle size for sports surface top layers and artificial turf infill, balancing foot comfort with structural stability.

What Core Problems Can EPDM Granules Solve for Users?

Whether you are a surface contractor, a sports facility buyer, or an artificial turf supplier, the concerns when choosing EPDM granules are usually practical ones: Will the granules fade quickly? Can they last under extreme climates? Are there odor or safety issues? Is there excessive dust during installation, and does it require too much binder?

2-4mm green EPDM granules address these needs at the material level. The saturated backbone structure of EPDM naturally provides resistance to UV, ozone, and temperature fluctuations. Moreover, the C-C crosslinks formed by peroxide vulcanization are more stable than the C-S bonds of conventional sulfur vulcanization, which means superior resistance to thermal aging and photodegradation. For users, the direct value is clear: surfaces retain their color and elasticity after years of use, reducing renovation frequency and long-term maintenance costs. At the same time, the sulfur-free formulation eliminates sulfide odor issues at the source—particularly critical for sensitive locations such as kindergartens and schools.

Applications and Advantages

Sports Surfaces: 2-4mm green EPDM granules are widely used in athletic track top layers, basketball courts, tennis courts, multi-purpose sports areas, and more. The angular, three-dimensional structure of the granules provides good anti-slip performance, while their elastic nature helps cushion impact during sports.

Artificial Turf Systems: As infill granules for artificial turf, the 2-4mm specification effectively supports grass filaments in an upright position, delivering a foot feel and rebound performance close to natural grass. It also solves the problem of natural grass going dormant in cold seasons.

Recreational and Safety Surfaces: Suitable for kindergarten play areas, park walkways, pool surrounds, fitness zones, and more. EPDM granules are non-toxic and odorless, meeting environmental requirements for children's activity areas. Their moderate elasticity can reduce impact from falls.

EPDM Mats and Prefabricated Rolls: 2-4mm granules are also a common raw material for producing rubber mats and prefabricated rolls. Combined with polyurethane adhesives, they can be manufactured into various elastic flooring products.

Durability Under Different Climates Worldwide

The weather resistance of EPDM granules is a core advantage that makes them globally applicable. Our products offer proven adaptability across different climate zones:

Hot and Humid Regions: Such as the Middle East, Southeast Asia, and parts of Africa. EPDM performs stably in high-temperature and humid environments. The peroxide-vulcanized structure resists degradation under sustained heat. In areas with intense UV radiation, we recommend using a UV-protective top coating to further extend color retention.

Cold and High-Temperature-Fluctuation Regions: Such as Northern Europe, North America, and Russia. EPDM maintains its elasticity at low temperatures and will not become brittle or crack due to freeze-thaw cycles, making it suitable for year-round outdoor use.

Rainy and Acid Rain Regions: EPDM has good resistance to water and dilute acids and bases. Rainwater will not cause the granules to soften or decompose. Surface drainage performance is not affected by the granules themselves.

High UV Regions: Such as Australia, Southern Europe, and high-altitude areas. The saturated hydrocarbon backbone of EPDM is the structural foundation for UV resistance. The 2-4mm green granules use high-quality pigments, and color stability has been rigorously tested.

FAQ

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

The core difference lies in the type of crosslink. Peroxide vulcanization forms C-C bonds, while sulfur vulcanization forms C-S or S-S bonds. C-C bonds have higher bond energy and greater stability. As a result, peroxide-vulcanized EPDM significantly outperforms sulfur-vulcanized systems in heat aging resistance and UV degradation resistance. This also means the product will not produce odor from sulfide precipitation during use.

What are the main applications for 2-4mm green EPDM granules?

The 2-4mm particle size is one of the mainstream specifications for sports surface top layers and artificial turf infill. Specific applications include: athletic track top layers, basketball/tennis courts and other sports surfaces, artificial turf infill, children's playground safety surfaces, and EPDM mat production.

What particle sizes and colors do you support for customization?

We support particle size customization from 0.5-1.5mm, 1-3mm, 1-4mm, 2-4mm, and other special specifications. For colors, we support RAL color card customization, Pantone color card customization, customer sample-based color matching, and various color combinations. Green can be matched to your required color code or sample.

Are the products environmentally friendly? Do they contain harmful substances?

Our EPDM granules use peroxide vulcanization technology and contain no sulfur in the formulation. The product is free from harmful substances such as polycyclic aromatic hydrocarbons (PAHs) and meets environmental requirements. The peroxide vulcanization system also avoids the use of zinc oxide and other additives common in sulfur vulcanization.

What is the minimum order quantity? Do you support LCL and FCL shipments?

The minimum order quantity is flexible. We support both LCL (less than container load) and FCL (full container load) shipments. We understand the differing needs of customers at various scales—whether it is a sample trial order or a container-level purchase, we can accommodate.

What is the typical lead time?

Regular specifications and colors are kept in stock and can be shipped quickly. For custom colors and special particle sizes, the production schedule is confirmed based on specific requirements. With over 25 years of industry experience and a complete set of advanced production lines, we can rapidly fulfill various order requirements.

How do you ensure color consistency between batches?

Strict quality control is implemented from raw material intake to finished product dispatch. We use high-precision color matching systems and standardized production processes. For large-volume orders, we recommend using the same batch or blending across batches to ensure visual uniformity.

Do you provide free samples?

Yes, we are happy to send free samples to customers worldwide for testing. Through actual testing, you can directly evaluate key indicators such as color, particle size distribution, elasticity, and odor.
