RAL 7011 EPDM Rubber Granules

RAL 7011, also known as iron grey, is a deep grey with a cool undertone—visually restrained and understated, often chosen for applications that demand dirt resistance and a technical aesthetic. Introducing this classic RAL colour into EPDM rubber granules means you receive not only a standardized deep grey colour, but a functional material that maintains colour stability and physical performance under harsh outdoor conditions. Our RAL 7011 EPDM granules use a peroxide vulcanization system and contain no sulfur, fundamentally avoiding the odour and environmental pollution issues that conventional vulcanization systems may produce under UV and high-temperature exposure. 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 focus exclusively on manufacturing EPDM granules and do not engage in installation, which allows us to devote all our efforts to formula optimization, colour consistency, and particle size precision control. 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.

From the Buyer's and User's Perspective: Core Problems EPDM Granules Solve

Whether you are a contractor selecting materials for a school sports field, a trader sourcing infill granules for an artificial turf system, or a manufacturer purchasing base material for playground safety mats, what you truly care about when it comes to EPDM granules boils down to a few simple yet critical questions: How long will the colour last? Will odour generate complaints? Will it harden and crack in winter? Is batch-to-batch colour variation controllable? Is supply stable?

Conventional rubber granules tend to fade, chalk, or become tacky on the surface under prolonged UV exposure and rain washing, while products using sulfur-based vulcanization systems may release unpleasant odours after high-temperature sun exposure. Our peroxide-vulcanized EPDM granules address these pain points at the molecular structure level: the saturated backbone of the EPDM elastomer itself offers excellent resistance to ozone, oxygen, UV, and temperature variation; the carbon-carbon bonds formed by peroxide crosslinking are more stable than the sulfur-sulfur bonds of sulfur vulcanization, significantly enhancing the granules' ability to maintain elasticity and colour during long-term outdoor exposure. For you, this means lower complaint rates, longer renovation cycles, and more predictable performance across different climates worldwide.

Applications and Advantages: Where RAL 7011 EPDM Granules Are Used and What Value They Deliver

The deep iron grey tone of RAL 7011 gives it unique adaptability across multiple application scenarios.

Various sports fields and running tracks. In athletic tracks and multi-purpose sports fields, deep grey granules can serve as a base colour or be combined with other bright-coloured granules to create clear field markings or zone distinctions. Their high elasticity and tensile strength (4–7 MPa) provide athletes with stable foot feedback, while the low bulk density and angular three-dimensional structure allow the granules to disperse evenly in polyurethane adhesive, resulting in a dense, firm surface that resists loosening.

Outdoor recreational sports areas and playground safety mats. Playgrounds and outdoor fitness areas require safety surfaces that combine impact absorption with long-term weather resistance. The deep tone of RAL 7011 helps mask dust and wear marks from daily use, while the anti-aging performance brought by peroxide vulcanization enables mats to maintain structural integrity after multiple rainy seasons and sun-exposure cycles, reducing thickness loss and safety performance degradation caused by granule chalking.

Artificial turf system infill. As elastic infill granules for artificial turf, RAL 7011 can be used alone or combined with green turf fibres to create a restrained visual contrast. Crucially, the sulfur-free formula does not produce irritating odours at high summer temperatures—particularly important for schools, communities, and commercial recreational venues. Meanwhile, the granules' UV stability ensures they resist fading under continuous sunlight, preventing infill layer discolouration from affecting the overall visual appearance of the turf.

Prefabricated EPDM mats and rolls. For factory customers processing prefabricated mats or rolls, batch-to-batch colour consistency of RAL 7011 granules directly affects the appearance pass rate of finished products. Through strict raw material screening and production process control, we ensure colour variation between batches is kept within an acceptable range, while supporting RAL, Pantone, and sample-based customization—so your finished products have a reference to match and a sample to verify against.

Durability performance across different national climates. The EPDM elastomer's service temperature range covers -50°C to 130°C, and this broad temperature window enables it to adapt from the severe winters of Northern Europe to the scorching summers of the Middle East. In rainy and humid regions (such as Southeast Asia and Western Europe), the saturated backbone structure of peroxide vulcanization offers good stability against water and polar chemicals, and the granules are less prone to degradation or mould growth from moisture absorption. In high-UV regions (such as the Middle East, Australia, and parts of Africa), their UV aging resistance ensures colour and elasticity remain stable under prolonged sun exposure. In cold regions (such as Northern Europe, Canada, and Russia), the granules do not become brittle at low temperatures like some thermoplastic materials, maintaining necessary flexibility and avoiding accelerated damage from freeze-thaw cycles in winter. This cross-climate adaptability fundamentally derives from the EPDM molecular structure itself, rather than relying on short-term protective coatings added later.

Frequently Asked Questions (FAQ)

Will the grey of RAL 7011 EPDM granules differ from the colour card after actual installation?

RAL colour numbers are reference colours for loose granules. The visual effect after installation is influenced by the adhesive colour, granule surface gloss, and ambient lighting. The low reflectivity of deep grey (RAL 7011) makes it relatively stable under different lighting conditions, but we still recommend making a small sample with the actual batch of granules before large-area installation. We offer free samples for your testing.

Does the sulfur-free formula mean the granules' physical strength is reduced?

Quite the opposite. The carbon-carbon crosslinks formed by peroxide vulcanization have higher bond energy. Combined with our process control, the product achieves a tensile strength of 4–7 MPa, with elasticity and tensile performance improved by 2–3 times compared to conventional sulfur vulcanization systems. What sulfur-free brings is not only odour control but comprehensive performance optimization through enhanced molecular structure stability.

What particle size specifications can you provide?

We support custom production of 0.5–1.5mm, 1–3mm, 1–4mm, 2–4mm, and special specifications. Different particle sizes suit different scenarios: finer sizes are suitable for artificial turf infill and thin-layer mats, while coarser sizes are more appropriate for playground safety mats or track base layers requiring higher void ratios and impact absorption.

What do I need to provide for colour customization?

You can provide RAL colour numbers, Pantone colour numbers, or simply send physical samples. Our colour matching team will match according to your sample and provide confirmation samples before mass production. We also support multi-colour combination customization for field designs requiring multi-colour patterns or zone identification.

What are the minimum order quantity and lead time?

Minimum order quantity is flexible and can be discussed based on your actual needs. With over 25 years of industry experience and a complete set of advanced production lines, we can respond quickly to various order requirements, support full-container and LCL shipments, and provide stable supply plans to match your project rhythm.

How do you confirm colour consistency between batches?

We conduct colour comparison and retain samples for each batch during production. For long-term cooperative customers, a standard colour sample file can be established, and subsequent batches are inspected against this standard. High colour consistency is one of the core indicators in our quality control system.

Are your granules environmentally friendly? Do they meet flame retardant requirements?

The product uses a sulfur-free peroxide vulcanization system, produces no sulfide pollution, has no odour, and causes no harm to the human body. The flame retardant rating is Class 1, suitable for public venues and areas around buildings with fire safety requirements.

Do you do installation? If not, how do you ensure usage results?

We only manufacture EPDM granules and do not undertake installation. This positioning allows us to focus on improving the quality of the material itself. We provide technical recommendations on granule-to-adhesive ratios and storage conditions, but specific installation processes and on-site condition control are the responsibility of professional installers. The stability of material performance is precisely the foundation for reducing installation risks and ensuring final results.
