1-3mm Purple EPDM Granules

1-3mm purple EPDM granules are a high-quality elastic rubber granule designed for sports surfaces, children's play areas, and landscape paving. We use peroxide vulcanization technology instead of the traditional sulfur vulcanization process, which fundamentally eliminates the odor and environmental pollution problems caused by sulfide residues. This means that under high temperature and strong ultraviolet radiation, the granules will not decompose into sulfuric acid substances, produce no odor, and are harmless to the human body. At the same time, the molecular structure is more stable, and the service life is significantly extended. Whether you are in the hot desert climate of the Middle East or the severe freezing and thawing environment of Northern Europe, 1-3mm purple EPDM granules can provide lasting color performance and elastic support.

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.

Core Problems We Help You Solve

As a buyer or project user, what you care about most when choosing granule materials is often not the parameters themselves, but whether these parameters can translate into stable performance in actual projects.

If you are worried about the surface fading and turning white under long-term sunlight, the peroxide vulcanization structure of 1-3mm purple EPDM granules gives them significantly better oxidation resistance and UV resistance than conventional products. The color retention rate is higher, and the purple tone is less likely to drift toward a dull gray.

If your region has strong UV radiation or drastic temperature differences, ordinary granules may harden, crack, or lose elasticity. Our granules, through a more stable C-C cross-linked bond network, maintain elastic recovery ability under high-temperature aging and freeze-thaw cycles, reducing later maintenance frequency.

If you have strict requirements for environmental compliance and human contact safety, the sulfur-free formula means no sulfide release, no odor, and is more suitable for schools, kindergartens, and scenarios sensitive to air quality.

If you need flexible customization rather than passively accepting stock specifications, we support on-demand adjustment of particle size, color, and packaging to help you achieve more precise material matching in your projects.

Applications

1-3mm purple EPDM granules are suitable for a variety of elastic paving systems. They can be used as surface layer aggregate mixed with polyurethane adhesive, or as raw material for prefabricated rolls:

- Sports surfaces: plastic running tracks, tennis courts, basketball court perimeters, multi-functional sports areas

- Children's play spaces: kindergarten activity areas, park playground safety surfaces

- Landscape and leisure: pedestrian walkways, courtyard paving, anti-slip surfaces around swimming pools

- Artificial turf systems: as infill granules to improve grass filament resilience and foot feel

This particle size specification balances aggregate three-dimensionality and construction workability in surface layer applications. The bulk density between granules is moderate, and the adhesive wetting effect is good.

Advantages

Weathering durability is the core value of EPDM granules. The peroxide vulcanization system of 1-3mm purple granules gives them excellent stability under extreme climate conditions. In the high-temperature and strong-sunlight environment of the Middle East, the granules are not easy to soften or exude; in the freeze-thaw cycles of Northern Europe or northern North America, the material maintains elasticity without becoming brittle. Purple, as a color system relatively sensitive to ultraviolet light, has better color fastness than conventional sulfur-vulcanized products due to the molecular stability brought by peroxide vulcanization.

In terms of physical properties, the product can achieve a tensile strength of 4-7 MPa, with good elongation at break and outstanding elastic recovery ability, providing the necessary impact absorption for sports surfaces. The granule surface is controlled and treated with low dust content, and the bonding efficiency with polyurethane adhesive is higher, which helps reduce glue usage and lower overall costs.

Environmental and safety performance is also noteworthy. The sulfur-free formula avoids the risk of sulfide release from the source, has no irritating odor, and is suitable for many types of indoor and outdoor scenarios. Products can be tested according to safety standards such as EN 71-3 to meet compliance requirements for heavy metal migration and PAHs content.

Frequently Asked Questions

How do I choose between 1-3mm purple EPDM granules and 2-4mm specifications?

Particle size selection mainly depends on the application scenario and designed surface thickness. 1-3mm is more suitable for fine surface paving, artificial turf infill, and scenarios requiring thinner coating systems; 2-4mm is commonly used for thicker elastic layers or venues with higher requirements for aggregate three-dimensionality. We can produce both specifications and can also provide particle size matching suggestions based on your construction plan.

Do peroxide-vulcanized EPDM granules really have no odor?

Yes. The root cause of odor problems usually comes from the decomposition of sulfide residues in sulfur vulcanization systems under light and high temperature. Peroxide vulcanization does not introduce sulfur elements, and the cross-linked structure is a more stable carbon-carbon bond, so it does not produce sulfide-type odors. This advantage is particularly obvious when used in enclosed spaces or high-temperature environments.

How long will purple granules fade outdoors?

The degree of fading depends on UV intensity and usage environment, but peroxide-vulcanized EPDM has an essential advantage in UV aging resistance. Purple, as an organic pigment coloring system, is more sensitive to ultraviolet light than dark color systems, but our molecular structure stability and pigment dispersion process allow it to maintain long-term visual consistency under reasonable use conditions. In high-UV areas such as the Middle East, it is recommended to use a UV topcoat to further extend color life.

What customization options do you support?

We support particle size customization (0.5-1.5mm, 1-3mm, 1-4mm, 2-4mm, and other special specifications), color customization (RAL color card, Pantone color card, sample-based customization), color combination matching, and packaging customization (bag specifications, label design). OEM, ODM, and Private Label are all available.

What is the minimum order quantity and delivery lead time?

The minimum order quantity is flexibly negotiated according to specifications and colors, and we support full container and LCL shipments. Regular specifications and standard colors usually have stable inventory for quick delivery; the production cycle for custom colors and special particle sizes depends on specific requirements.

Can you provide free samples for testing?

Yes. We are happy to send free samples so you can evaluate the color, particle size distribution, elastic feel, and compatibility with adhesives.
