Do UV-Resistant EPDM Granules Age in High-Temperature Regions

In environments with high temperatures and intense UV radiation, UV-resistant EPDM granules demonstrate exceptional resistance to aging. Thanks to innovative sulfur-free vulcanization technology, the product’s molecular structure is highly stable, completely eliminating the problem of odor caused by decomposition at high temperatures. With significantly enhanced resistance to aging and high temperatures, as well as a markedly extended service life, these granules are the ideal choice for outdoor facility construction in hot regions.

Addressing the Challenges of High Temperatures and UV Radiation: How Our Product Solves Key Issues

For sports fields or kindergarten playgrounds in hot regions, materials exposed to intense heat and sunlight often face two key issues: first, the release of sulfur compounds that produces an unpleasant odor, affecting the user experience; second, the breakdown of molecular chains, which leads to reduced elasticity and color fading, significantly shortening the facility’s service life. Through technological innovation, our sulfur-free EPDM granules specifically address these issues:

Eliminating High-Temperature Odors: By adopting a sulfur-free vulcanization system, we prevent the decomposition of sulfuric acid caused by high temperatures and UV exposure at the source, ensuring fresh air even in sweltering conditions—making the product safe for both people and the environment.

Resisting Aging and Discoloration: A unique formulation design greatly enhances UV resistance and antioxidant properties. Even after prolonged exposure to intense sunlight, the granules retain their vibrant color over time and are resistant to whitening or fading.

Ensuring Long-Term Physical Properties: Sulfur-free technology stabilizes the molecular structure, increasing the product’s elasticity and tensile strength to 4–7 MPa and improving performance retention by more than five times. This effectively resolves the issues of material hardening and wear at high temperatures, significantly extending the service life.

Core Advantages and Product Value of Sulfur-Free EPDM Granules

Choosing our products means choosing a solution that stands the test of time. With over 25 years of industry expertise and advanced production lines, we offer more than just materials—we provide a guarantee of quality.

1. Exceptional Aging and Weather Resistance

Our products exhibit excellent resistance to UV (ultraviolet) radiation and ozone. Tests show that conventional EPDM undergoes photo-oxidative degradation when exposed to UV light, whereas our sulfur-free formulation significantly inhibits this process. With an aging resistance lifespan 3–5 times longer than comparable products, it is ideal for outdoor applications subject to year-round exposure.

2. Environmental Safety and Physical Properties

Our materials meet food-grade environmental standards; they are odorless and sulfur-free, eliminating the environmental pollution risks associated with traditional sulfur vulcanization. Additionally, the product features a low bulk density and a distinct three-dimensional texture, which not only reduces material consumption during installation but also provides excellent slip resistance and shock absorption, effectively protecting athletes’ joints.

3. Flexible Customization and Fast Delivery

We understand the unique color requirements of different projects. We offer customization services for the full color spectrum and specific granule sizes, with flexible minimum order quantities. Whether you need vibrant surfacing for a kindergarten or professional-grade colors for a sports track, we can respond quickly and fulfill your order using our comprehensive set of advanced production lines.
