Will Sulfur Free EPDM Granules Affect Color Vividness

Sulfur free EPDM granules not only do not affect the brightness of colors, but can significantly enhance the durability of colors. Traditional sulfur-containing granules are prone to decompose and produce sulfuric acid under high temperature or strong ultraviolet radiation, accelerating pigment fading; And sulfur free technology makes the molecular structure more stable, combined with antioxidant function, effectively resists UV aging, and ensures long-lasting bright colors.

As a manufacturer of custom EPDM rubber granules, we understand the challenges you face when searching for high-quality, odorless, and long-lasting elastic flooring materials. Our sulfur free EPDM granules can perfectly solve the problems of traditional materials such as fading, odor, and aging. We provide you with customized solutions that are environmentally friendly, durable, and colorful, meeting your comprehensive needs for safety, aesthetics, and long-term performance.

How sulfur free technology reshapes color stability and physical properties

The improvement of EPDM granules by sulfur free process is systematic, especially in maintaining excellent color vividness.

The leap of anti-oxidation and anti-aging properties

Traditional sulfur-containing EPDM granules will gradually precipitate sulfur and undergo chemical reactions under UV irradiation and high temperature environments, forming sulfuric acid substances. This not only produces irritating odors, but also accelerates the breakage of rubber molecular chains, leading to material aging and discoloration. Sulfur free technology fundamentally eliminates the unstable factor of sulfur, making the molecular structure of the product more stable. In terms of ozone aging resistance, the performance retention rate of sulfur free products is more than 5 times higher than that of sulfur containing products, which can effectively resist the erosion of ultraviolet rays, ozone, and acid rain, thus maintaining the bright color for a long time and avoiding powdering and fading.

Comprehensive enhancement of physical performance

Sulfur free EPDM granules not only focus on the surface, but also have excellent intrinsic physical properties:

Elasticity and tensile strength: The product's elasticity and tensile strength are increased by 2-3 times, reaching 4-7 megapascals, which means better sports cushioning performance and impact resistance.

Service life: Due to the significantly improved stability of the molecular structure, the overall service life of the product can be increased by more than three times, reducing the trouble of frequent replacement.

Stacking density and three-dimensional effect: The granule stacking density is low, and it has the characteristics of strong angular three-dimensional effect. After paving, it not only saves material consumption, but also forms a more beautiful and anti slip textured surface.

Customer Application Case (Anonymous)

Background: A large international school in Southeast Asia plans to upgrade its outdoor comprehensive sports area in early 2025, including a standard football field, two basketball courts, and a children's play area. The general contractor of the project faces two major challenges: firstly, the local climate is hot and rainy all year round, and the ultraviolet radiation is extremely strong. Traditional granules fade and turn white less than a year after installation, requiring frequent color repair; Secondly, the school has extremely strict environmental requirements, explicitly requiring materials to be odorless and meet food contact level hygiene standards.

Solution and Implementation: We provided a customized sulfur free EPDM granule solution for this project. For football and basketball courts, we use granules with high tensile strength (6.2 megapascals) to ensure that they are not easily worn out during intense exercise; For the children's play area, more brightly colored fine-grained granules were customized for mosaic patterns. All products are produced according to food grade standards and provide weather resistance test reports.

Delivery result: The site will be delivered for use in January 2026. After six months of testing during the hot and rainy season, in a follow-up visit in June 2026, the school facility manager provided feedback: "The color of the venue is maintained very well, and there is almost no difference from when it was first laid, especially after being exposed to high temperatures. There is no pungent smell on the track. The children really like it, which completely exceeds our expectations." This case has become the designated reference standard for the construction of other campuses by the school in the future.
