Can Sulfur Free EPDM Colored Granules Be Used in Sports Fields

The sports field can completely use sulfur free EPDM colored granules. Sulfur free EPDM granules not only meet the performance requirements of sports fields, but also completely solve the problem of traditional granule odor disturbance by relying on the sulfur free formula's characteristics of not decomposing sulfuric acid and not producing odor under high temperature and strong ultraviolet irradiation. Its molecular structure is more stable, its service life is more than three times longer, its tensile strength reaches 4-7 MPa, and it has excellent anti-aging, anti-oxidation and high temperature resistance properties. Its color is bright and durable, and its environmental protection level can reach the food level health standard. It is an ideal choice for high-quality sports venues.

As a sports venue construction party or material purchaser, your most concerned core needs are: whether the venue is safe and environmentally friendly, whether the performance is durable, whether the colors are beautiful and bright, and whether the construction is smooth and worry free. Our sulfur free EPDM colored granules are designed to meet these core needs. It is odorless, more environmentally friendly, and ensures the health of users; Super tensile strength and anti-aging performance greatly improve the service life of the site and reduce long-term maintenance costs; Colorful and long-lasting, meeting the aesthetic design needs of various venues; At the same time, we provide flexible color and granule size customization services with low minimum order quantity threshold and fast delivery speed, making your procurement and construction more efficient and worry free.

Core advantages and application value of sulfur free EPDM colored granules

The sulfur free EPDM colored granules adopt innovative sulfur free vulcanization technology, fundamentally changing the performance boundary of traditional EPDM granules. The following are its core technological features and the actual value it brings to users:

1. Truly odorless and environmentally friendly, meeting food grade standards

Due to the complete absence of sulfur components in the formula, the product will not decompose and produce irritating gases such as sulfuric acid under high temperature exposure and strong ultraviolet radiation, thus eliminating odor problems from the source. At the same time, the product has excellent environmental performance and can meet food grade hygiene standards, making it particularly suitable for places with high environmental requirements such as kindergartens and schools.

2. The molecular structure is super stable, and the service life is increased by more than 3 times

Sulfur free technology makes rubber molecular cross-linking structure more compact and stable, and anti-aging performance is greatly enhanced. Under long-term exposure to sunlight and rain outdoors, the performance retention rate is increased by more than 5 times, and the service life is more than 3 times that of traditional granules, significantly reducing the frequency of site renovation and long-term operating costs.

3. Double the elasticity and tensile strength, excellent athletic performance

The elasticity and tensile strength of the product are increased by 2-3 times, with a tensile strength of 4-7 megapascals. It has excellent impact absorption and energy feedback performance, which can effectively reduce sports injuries and provide athletes with a more comfortable foot feel and safer protection.

4. Antioxidant, high temperature resistant, and long-lasting bright colors

The product has strong antioxidant and high temperature resistance, and remains stable under extreme weather conditions. The color vividness far exceeds that of traditional granules, and it is not easy to fade or discolor, maintaining the beauty of the venue for a long time and reducing the need for renovation due to fading.

5. Low packing density, strong three-dimensional sense, and good construction adaptability

The granules have distinct edges, strong three-dimensional sense, low packing density, larger bonding area with glue, stronger adhesion, more uniform paving, higher construction efficiency, and better surface flatness and aesthetics of the finished product.

What application challenges can we solve for you?

In actual sports field construction, users often face the following challenges, and sulfur free EPDM colored granules provide a systematic solution:

Difficulty in odor complaints: Traditional granules release odors at high temperatures, causing complaints from surrounding residents or parents. The sulfur free formula eliminates odors from the root and completely solves the contradiction between environmental protection and user experience.

Premature aging and fading of the venue: Ordinary granules will show significant fading, powdering, and threshing within 2-3 years. The performance retention rate of sulfur free granules has been increased by more than 5 times, and it will remain in good condition for 5-8 years, significantly extending the lifespan of the site.

Elastic attenuation and insufficient motion protection: Traditional granules experience a decrease in elasticity over time, losing their buffering and protective functions. The tensile strength of sulfur free granules reaches 4-7 megapascals, with long-lasting and stable elasticity, ensuring long-term sports safety.

Single color and limited design: Traditional granule color options are limited, making it difficult to meet personalized design needs. We support full-color customization and can accurately match colors according to Pantone color codes to meet various creative patterns and brand visual needs.

Long procurement cycle and high minimum order quantity: Small batch customized orders are often rejected by large factories or have long delivery times. We offer flexible minimum order quantities, with regular colors shipped within 3-5 days and customized colors delivered within 7-10 days to quickly respond to project progress.

Customer Application Cases

Case 1: A Key Middle School Playground Renovation Project

The school's original plastic track used traditional sulfur-containing EPDM granules, which experienced severe fading and threshing in just 3 years, and had a noticeable odor during high temperatures in summer. It has received multiple complaints from parents. In the summer of 2025, the school decided to carry out a comprehensive renovation and use our sulfur free EPDM colored granules (granule size 1-2mm, red and blue dual color matching). After construction, the site has bright and uniform colors without any odor, and the satisfaction of parents has significantly increased. After a year of use and follow-up, the elasticity and color retention rate of the venue have exceeded 95%. The school has provided feedback that it has completely solved the long-standing problems of odor and aging, and has listed our company as the designated supplier for subsequent campus construction.

Case 2: A high-end community children's playground and fitness trail

The community has extremely high requirements for environmental protection and safety. The original plan was to use imported materials, but the cost was too high. After comparative testing, our sulfur free EPDM granules outperform similar imported products in key indicators such as odor, elasticity, and weather resistance, and have a more competitive price. We ultimately chose our customized color scheme (Morandi Green+Warm Grey) with a granule size of 0.5-1.5mm to create a soft and comfortable children's activity area. After the completion of the project, community owners provided feedback that "children can run barefoot with peace of mind" and "there is no odor even after rain". The property management stated that maintenance costs have been reduced by 40% compared to expectations, making it a benchmark project in the area.

Case 3: Outdoor Training Ground of an International Chain Gym

The outdoor training area of this gym needs to withstand high-frequency equipment dragging and high-intensity training impacts, with extremely high requirements for material tensile strength and wear resistance. Our company customizes high hardness, high tensile sulfur free EPDM granules (with a tensile strength of 6.5 megapascals) with a granule size of 1-2mm and a black+fluorescent yellow contrasting design. After 18 months of use, there was no significant wear or peeling on the venue, and the elasticity attenuation was less than 5%. The gym manager stated that it exceeded expectations and plans have been made to replicate the solution in other stores.
