6-13MPa Tensile Strength EPDM Granules

In sports surfaces, playgrounds, and high-end rubber flooring applications, the tensile strength of EPDM granules is a core indicator of their durability and load-bearing capacity. The 6-13MPa tensile strength range means the granules maintain high elasticity while possessing outstanding tear resistance and deformation resistance, capable of meeting the demanding requirements from professional running tracks to high-traffic playgrounds. 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.

What Core Problems Can EPDM Granules Solve for You?

As a buyer or end user, what you care about most is whether the product can solve real problems stably over the long term within your budget. Our 6-13MPa tensile strength EPDM granules respond to your core concerns from the following dimensions:

Color durability challenges. Traditional rubber granules often show significant fading and whitening within 1-2 years under outdoor UV exposure. The saturated structure of the EPDM molecular backbone inherently provides weather resistance, and peroxide vulcanization technology further enhances color stability, allowing granules to maintain their original color under prolonged sunlight exposure.

Safety and environmental compliance pressure. Kindergartens, schools, and public sports venues have increasingly strict requirements for non-toxic and harmless materials. Our peroxide vulcanization system eliminates the introduction of sulfur components from the source. Under high temperature and UV conditions, it does not decompose to produce sulfides, has no irritating odor, and meets strict environmental and human contact safety standards.

Excessive maintenance costs. Inferior granules develop powdering, cracking, or elasticity loss within a short period, leading to frequent renovation. High tensile strength means granules are resistant to breaking or deformation under long-term foot traffic and equipment rolling. Combined with excellent aging resistance, this significantly extends surface service life and reduces full-lifecycle maintenance costs.

Insufficient climate adaptability. Climate conditions vary dramatically across different countries—extreme heat in the Middle East, severe freezing and thawing in Northern Europe, and persistent high humidity with heavy rainfall in Southeast Asia. Our EPDM granules demonstrate excellent adaptability across major global climate zones: maintaining stable performance within an operating temperature range of -40°C to 120°C, resistant to rain erosion, and ready for use immediately after rain.

Applications and Core Advantages

Main Application Scenarios

Our 6-13MPa tensile strength EPDM granules are widely used in: rubber running tracks (permeable and hybrid surface layers), kindergarten and playground safety flooring, fitness trails and community activity areas, artificial turf infill granules, rubber tiles and prefabricated rolls, and high-end courtyard landscape paving.

Advantage Analysis: Practical Value Delivered to Users

Climate durability, globally applicable. Different countries have vastly different requirements for material climate adaptability. For the Middle East and tropical regions, the granules' high-temperature stability and UV resistance ensure they do not soften or fade at surface temperatures above 50°C. For Northern Europe and North America's cold regions, the low glass transition temperature (Tg approximately -60°C) guarantees no embrittlement or cracking in winter. For Southeast Asia and rainy regions, water vapor resistance and low water absorption prevent mold and degradation in persistently humid environments. Over fifty years of global sports surface application experience has fully validated EPDM's comprehensive resistance to ozone, oxygen, UV, and temperature.

Performance leap from peroxide vulcanization. EPDM granules using the peroxide vulcanization system have a molecular crosslinking network primarily based on more stable C-C bonds, rather than the C-S or S-S bonds of sulfur vulcanization systems. Research shows that peroxide-vulcanized rubber significantly outperforms sulfur-vulcanized systems in aging resistance and compression set resistance. This means our granules are less likely to harden, crack, or lose elasticity during long-term use, with service life extended by more than 3 times. Elasticity and tensile strength reach 4-7MPa (customizable to the 6-13MPa range depending on formulation and particle size specifications).

Color consistency is the foundation of stable supply. For users undertaking large-scale projects, color variation between batch purchases is a common pain point. We implement strict color control from raw material batch management to finished product packaging. We support RAL and Pantone color card customization, and also accept customer color samples for matching, ensuring color consistency across different order batches.

Low bulk density, higher coverage rate. Our granules feature low bulk density and a strong three-dimensional angular shape. This means during installation, the same weight of granules can cover a larger area, indirectly saving you material usage and overall costs.

Frequently Asked Questions

What does 6-13MPa tensile strength mean? How do I choose between different strength levels?

Tensile strength reflects a granule's ability to resist tensile fracture. 6MPa is suitable for general playground flooring and low-intensity sports areas; 8-10MPa suits school playgrounds, community fitness trails, and medium-intensity scenarios; the 13MPa grade is recommended for professional track surface layers, high-traffic sports venues, and projects with demanding durability requirements. We can recommend the most economical strength grade based on your project type.

Are your products truly sulfur-free? Are they safe for children?

Yes. Our entire EPDM granule line uses peroxide vulcanization technology, which does not introduce sulfur components during the vulcanization process. The products contain no sulfur and will not decompose to produce sulfuric acid substances under high temperature and strong UV exposure. They are odorless, pollution-free, and harmless to the human body. This characteristic is particularly important for sensitive locations such as kindergartens and schools.

How long can the granules last in areas with intense UV radiation (such as the Middle East and Australia)?

Our EPDM granules perform excellently in artificial accelerated aging tests. According to industry standards, under UVA exposure approaching 5,000 hours, the color gray scale rating can still be maintained at 3.5-4, far exceeding the standard requirement of ≥3. This means that in areas with intense UV radiation, the color retention period can reach 8-10 years or more under normal use conditions.

Will they harden and crack in winter in cold regions?

No. EPDM's glass transition temperature is approximately -60°C, maintaining good flexibility even at extremely low temperatures. The product's operating temperature range is -40°C to 120°C, suitable for winter climate conditions in high-latitude markets such as Northern Europe, Canada, and Russia.

What colors and particle sizes can be customized? What is the minimum order quantity?

For colors, we support RAL color card and Pantone color card customization, and can also match colors based on customer-provided samples. Standard particle sizes include 0.5-1.5mm, 1-3mm, 1-4mm, and 2-4mm, with special particle sizes available upon request. Minimum order quantities are flexible, and trial orders are supported.
