2-4mm Colored EPDM Granules

2-4mm colored EPDM granules are colored rubber granules made from ethylene propylene diene monomer (EPDM) rubber through a peroxide vulcanization process. This particle size specification is one of the most widely used sizes in sports surfaces and recreational paving systems, balancing the convenience of installation with the fine texture of the finished surface. Our EPDM granules have excellent property of weather resistance. 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 the environment, no odor and no harm to the human body. We are a professional manufacturer specializing in custom EPDM granule production. We only produce EPDM granules; we do not undertake installation. 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 Can 2-4mm EPDM Granules Solve for Users?

In the practical application of sports surfaces and recreational paving, buyers and end users often face several key pain points. Fading directly affects the aesthetics of the venue and the pass rate of acceptance inspections — especially in regions with strong UV radiation, inferior granules may show noticeable color differences within months. Odor and environmental concerns relate to the health and safety of users, particularly children; products made with sulfur-based vulcanization may release irritating odors at high temperatures. Insufficient durability leads to frequent repairs or premature replacement of the surface, increasing lifecycle costs. Low-temperature embrittlement limits application in cold regions, where ordinary rubber granules may harden and crack in sub-zero environments. Poor drainage causes water accumulation, affecting rapid recovery of use after rain. 2-4mm EPDM granules are designed precisely to address these core issues.

Applications and Advantages

Main Application Scenarios

Various sports fields and running tracks: 2-4mm colored EPDM granules are an ideal choice for the surface layer of plastic running tracks and can be used for athletic tracks, basketball courts, tennis courts, volleyball courts, and other multi-functional sports venues. The elastic nature of the granules effectively absorbs sports impact and reduces the risk of joint injury.

Outdoor recreational sports areas: Including community fitness paths, park walkways, senior activity centers, and youth activity zones. The 2-4mm particle size provides comfortable foot feel and anti-slip performance, suitable for all-weather use.

Artificial turf systems: As infill granules for artificial turf, 2-4mm EPDM granules support the grass filaments to stand upright, prevent lodging, and provide the cushioning performance required for sports. Their good drainage ensures the field does not accumulate water on rainy days.

EPDM mats and prefabricated products: Used to make rubber mats, safety tiles, and other prefabricated products, providing impact absorption and anti-slip functions, suitable for playground safety surfaces and gym floors.

Core Advantages

Excellent weather resistance and temperature tolerance: The saturated hydrocarbon backbone structure of EPDM gives it outstanding resistance to ozone, UV, and oxygen aging. The product maintains elasticity within a temperature range of -50°C to 150°C. This means that in the hot and humid environments of the Middle East and Southeast Asia, the granules will not soften, deform, or accelerate aging; in the severe cold regions of Northern Europe and North America, the granules will not become brittle or crack; in rainy tropical regions, the large-gap structure ensures rapid rainwater infiltration without water accumulation or muddiness.

Sulfur-free peroxide vulcanization technology: Unlike traditional sulfur vulcanization processes, we use a peroxide vulcanization system. This cross-linking method forms stable carbon-carbon bonds on the saturated backbone of EPDM, with no residual sulfur components in the product. Therefore, under high temperatures and strong UV radiation, it does not decompose into sulfuric acid, fundamentally eliminating odor and pollution problems. It is harmless to the human body and especially suitable for campuses and children's activity areas.

Long-lasting and stable color: Using high-quality pigments and a stable formulation system, combined with the molecular structural stability brought by peroxide vulcanization, the granules maintain vibrant color under long-term outdoor exposure and are resistant to fading and whitening, reducing the need for surface renovation due to color degradation.

High elasticity and sports safety: The surface layer formed by 2-4mm granules has appropriate elasticity and resilience, absorbing foot impact, reducing sports injuries, and not excessively consuming physical energy.

Frequently Asked Questions (FAQ)

What specific types of venues are 2-4mm EPDM granules suitable for?

2-4mm is one of the most versatile particle size specifications. Typical applications include: plastic running track surface layers, school playgrounds, kindergarten activity areas, community fitness areas, artificial turf infill, playground safety surfaces, and various EPDM mat products. This particle size has good flowability and compactability during installation, and the finished surface is flat and fine.

How do your granules perform under extreme climate conditions?

The molecular structure of EPDM determines its wide temperature range adaptability. In high-temperature regions (such as the Middle East and Southeast Asia), the granules will not soften or release odor due to high temperatures; in severe cold regions (such as Northern Europe and Canada), the granules maintain elasticity without becoming brittle; in rainy regions, the large pore structure between granules ensures rapid drainage. Our granules have been verified in different climate zones worldwide, with stable and lasting performance.

What is the difference between peroxide vulcanization and sulfur vulcanization? Why is this important for purchasing decisions?

Peroxide vulcanization forms carbon-carbon cross-linking bonds on the saturated backbone of EPDM, while sulfur vulcanization relies on unsaturated double bonds. Peroxide-vulcanized products have a more stable molecular structure, specifically: no sulfur content, no sulfuric acid or odor at high temperatures; better heat aging resistance; lower compression set; and significantly extended service life. For buyers who value environmental compliance and long-term use costs, peroxide-vulcanized products are the better choice.

What is your minimum order quantity? Can you provide free samples?

We understand the different needs of customers of various scales. We support flexible minimum order quantities, and can accommodate both full container and LCL shipments. We are willing to send you free samples so that you can fully test the particle size, color, elasticity, odor, and other key indicators before bulk purchasing.

Yes. We support RAL color customization, Pantone color customization, and color customization based on customer samples. In addition to the standard 2-4mm specification, we also offer 0.5-1.5mm, 1-3mm, 1-4mm, and other special particle size specifications. We support multiple color combinations to meet your personalized needs for venue color design.

Do your granules have relevant environmental certifications?

Our EPDM granules are produced from virgin EPDM raw materials and do not contain heavy metals, polycyclic aromatic hydrocarbons, and other impurities brought by waste tire rubber powder. The products meet SGS environmental standard requirements, and the peroxide vulcanization process avoids sulfide pollution from the source.
