3mm Colored EPDM Granules

3mm colored EPDM granules are high-elasticity colored rubber granules made from ethylene propylene diene monomer (EPDM) as the base material, manufactured through a peroxide vulcanization process. This particle size specification has broad applicability in sports surfaces and artificial turf systems. It can serve as an elastic infill layer in artificial turf systems to provide foot-feel support, and can also be used as a functional layer for running tracks, playground surfaces, and fitness paths. 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.

As a professional EPDM granule manufacturer, we only produce granules and do not engage in construction. This allows us to devote all our efforts to formula development, process control, and quality consistency management. This means that every batch of EPDM granules shipped from our factory undergoes independent quality inspection, free from interference from construction schedules and on-site conditions.

What Core Problems Can 3mm Colored EPDM Granules Solve?

Elasticity and Athletic Performance of Artificial Turf Systems

During long-term use of artificial turf, the elasticity degradation of the infill layer directly affects athletes' joint stress and field performance. 3mm EPDM granules filled between grass filaments provide stable shock absorption and rebound support, reducing hard impacts during sports. Compared to systems filled only with silica sand, EPDM elastic granules can significantly improve the field's athletic foot feel and energy return.

Weather Resistance Concerns for Outdoor Surfaces

The biggest concern for many buyers is: after the granules are installed, will they fade, become brittle, or develop odors after two or three years? Under the combined action of ultraviolet radiation and high temperatures, the molecular chains of traditional sulfur vulcanization systems are prone to breaking, causing granules to harden, colors to dull, and even odors to develop. We use peroxide vulcanization technology, which gives the molecular structure greater stability and fundamentally delays the aging process.

Performance Retention in High-Temperature and Humid Climates

Climate conditions vary enormously across different countries and regions — the intense heat and sunlight of the Middle East, the high humidity and rainfall of Southeast Asia, the low-temperature freeze-thaw cycles of Northern Europe, and the strong ultraviolet radiation of South America. 3mm colored EPDM granules, relying on the saturated backbone structure of the EPDM base material itself, maintain elasticity and physical properties across a wide temperature range from -50°C to 150°C. Whether under the scorching sun of equatorial regions or freeze-thaw cycles of cold zones, the granules maintain stable morphology and function.

Environmental Compliance and Human Contact Safety

Scenarios such as schools, kindergartens, and community activity areas have increasingly strict environmental requirements for materials. Our granules are sulfur-free, odorless, and do not produce sulfide pollution, meeting the basic safety requirements for human contact scenarios.

Applications

Artificial turf elastic infill systems are one of the core application scenarios for 3mm EPDM granules. As the elastic infill layer of artificial turf, 3mm granules form a uniform support structure between grass filaments, stabilizing grass filament uprightness while providing the shock absorption and rebound performance required for sports. Suitable for football fields, rugby fields, baseball fields, and multi-purpose sports turf systems.

In addition, 3mm colored EPDM granules are widely used in:

- Running track surfaces: As colored anti-slip granules for running track surfaces, providing grip and visual zoning functions.

- Playground safety surfaces: Elastic safety layers for children's activity areas and kindergarten surfaces, reducing fall impact risks.

- Fitness paths and community activity areas: Functional surfacing for outdoor fitness equipment surroundings, walkways, and leisure areas.

- Basketball courts, tennis courts, and multi-purpose courts: Elastic surface aggregate for sports venues.

- Landscape and architectural decoration: Colored elastic decorative materials for building facades and courtyard paving.

Core Product Advantages

Fundamental Improvements Brought by Peroxide Vulcanization

Our EPDM granules use a peroxide vulcanization system rather than traditional sulfur vulcanization. This process difference brings substantive changes at the molecular level: the bond energy of carbon-carbon crosslinks is higher than that of carbon-sulfur and sulfur-sulfur bonds, resulting in significantly better resistance to thermal aging and UV degradation. In laboratory accelerated aging tests, the tensile strength retention of peroxide-vulcanized EPDM remains at 80% after 2000 hours of aging, compared to only 50% for sulfur-vulcanized systems.

Specific product performance:

- Odorless, no sulfide release: Does not decompose into sulfuric acid under high temperature and strong UV irradiation, produces no odor, no pollution, and no harm to human body.

- More stable molecular structure, with service life extended by more than 3 times.

- Elasticity and tensile strength increased by 2-3 times, with tensile strength reaching 4–7 MPa.

- Performance retention rate increased by more than 5 times, greatly enhancing aging resistance.

- Better antioxidant function, more vivid colors, and resistance to discoloration.

- Better high-temperature resistance, more environmentally friendly.

- Flame retardant rating of Class 1.

- Low bulk density, strong angular three-dimensional appearance.

Global Climate Adaptability

The saturated backbone structure of EPDM gives it natural resistance to ozone, UV radiation, heat, humidity, and extreme temperatures. For the actual climate conditions of different export markets:

- Hot and dry regions (Middle East, North Africa, Australia): The peroxide vulcanization system resists degradation under sustained high temperatures. Granules do not become sticky or deform, and color retention periods are long.

- Hot and humid regions (Southeast Asia, tropical South America): The hydrophobic nature of EPDM prevents water absorption and swelling in long-term humid environments. Elasticity remains stable with no risk of mold.

- High UV regions (plateaus, equatorial zones): Carbon-carbon crosslinks effectively resist UV-induced molecular chain breakage. Fading rates under outdoor exposure are significantly lower than sulfur-vulcanized products.

- Cold freeze-thaw regions (Northern Europe, Canada, Russia): EPDM does not harden or become brittle at low temperatures, maintaining structural integrity after repeated freeze-thaw cycles.

- High rainfall regions (UK, Japan, Pacific island nations): The three-dimensional angular structure of the granules provides good water permeability and drainage. Long-term rainwater immersion does not affect physical properties.

Frequently Asked Questions (FAQ)

Where are 3mm EPDM granules mainly used?

3mm is one of the most widely used particle sizes. In artificial turf systems, it is used as elastic infill granules, and it can also be used for running track surfaces, playground surfaces, and fitness areas. Its size forms a good filling and support effect between grass filaments — it will not be blown away or kicked out like smaller particles, nor will it affect field flatness like larger particles.

What is the difference between peroxide vulcanization and sulfur vulcanization?

The core difference lies in the molecular crosslink structure. Sulfur vulcanization forms carbon-sulfur and sulfur-sulfur bonds, while peroxide vulcanization forms carbon-carbon bonds. Carbon-carbon bonds have higher bond energy, so peroxide-vulcanized EPDM performs better in heat aging resistance and UV degradation resistance. In addition, the peroxide vulcanization system contains no sulfur, so it will not release sulfides under high temperature or UV irradiation, fundamentally avoiding odor and pollution problems.

How long can your granules last outdoors?

Under normal outdoor exposure conditions, our peroxide-vulcanized EPDM granules have an expected service life of 8–10 years or more, far longer than conventional sulfur-vulcanized products. Actual lifespan depends on specific climate conditions, UV intensity, frequency of use, and maintenance. We recommend keeping them dry and avoiding direct UV exposure during storage.

Will the granules fade?

EPDM itself has excellent color stability. Our peroxide vulcanization system further enhances aging resistance, resulting in longer color retention periods. In high UV regions, fading may be slightly faster than in temperate zones, but overall, our granules have a significant color retention advantage over similar products.
