In the scorching summer, many venue owners often face a problem: EPDM plastic venues emit a pungent odor after being exposed to high temperatures. This is not the smell of rubber itself, but the manifestation of ordinary EPDM granules. under the dual effects of strong ultraviolet radiation and high temperature, where the sulfurizing agent added inside decomposes and releases harmful gases such as sulfur dioxide.
For homeowners, purchasers, and construction companies facing complaints about venue odors, your core needs are nothing more than: completely eliminating venue odors, ensuring sports and health, extending the service life of the venue, and reducing later renovation costs. Our sulfur free custom EPDM granules. are designed to tackle these challenges, ensuring that your venue can maintain an excellent state of odorlessness, safety, and high elasticity no matter how extreme the heat is.
In the production process of ordinary EPDM granules., the traditional "sulfur vulcanization" process is usually used to crosslink rubber molecules. Although this process has a lower cost, it has fatal flaws:
Residual sulfurizing agents and high-temperature decomposition: Traditional sulfurization systems cannot achieve a 100% reaction conversion rate, and there will inevitably be residual free sulfur, sulfurization accelerators, and other substances inside the granules.. When the surface temperature reaches 60 ℃ -70 ℃ in summer, under strong ultraviolet catalysis, these residues undergo thermal degradation, decomposing into trace amounts of acidic gases such as hydrogen sulfide (H ₂ S) and sulfur dioxide (SO ₂), which is the direct source of the pungent "odor".
Molecular chain breakage and aging: High temperature and ultraviolet radiation can damage the "polysulfide bonds" formed in ordinary sulfurization systems. These chemical bonds have low energy and are easily broken, causing the particle surface to become sticky and powdery, further accelerating gas release.
After years of research and development, our company has abandoned traditional sulfur cross-linking and adopted an advanced sulfur free vulcanization system, giving our products unparalleled absolute advantages and creating core value for users
Eliminate odors from the source (core value): Free of any sulfur components, no matter high temperature exposure or strong ultraviolet radiation, never decompose sulfuric acid and sulfur-containing gases, truly achieving "zero odor" and ensuring respiratory health.
The molecular structure is extremely stable and the lifespan has increased: sulfur free technology forms high bond energy carbon carbon cross-linking bonds, which are extremely stable in structure. The product's service life is increased by more than 3 times, the performance retention rate is increased by more than 5 times, and the depreciation and refurbishment costs for customers are significantly reduced.
Breakthrough in physical performance: elasticity and pulling force increased by 2-3 times, and tensile strength reached 4-7 megapascals. This means that the venue is more slip resistant and has better shock absorption effects, effectively reducing the risk of sports injuries.
UV resistance and high temperature resistance: aging resistance and high temperature resistance are greatly improved. Not softened in summer, not hard and brittle in winter, maintaining optimal athletic performance all day long.
Food grade environmental protection, long-lasting color: more antioxidant function, brighter color and less prone to discoloration; The environmental standards far exceed the standards, even reaching food grade hygiene standards, and are extremely friendly to children and sensitive populations.
Construction friendly, cost reducing and efficiency increasing: low packing density, strong three-dimensional sense of water chestnut. Laying a larger area under the same weight not only saves glue usage, but also presents a more three-dimensional texture of the venue.
In practical applications, our sulfur free EPDM granules. accurately solve many customer problems:
Kindergarten/Children's Playground: Addressing the risk of children being harmed by odors during sensitive periods, food grade standards provide parents with absolute peace of mind.
Professional sports venues: solve the problem of particle powdering and hardening under high-frequency use, leading to a decrease in anti slip and shock absorption, with a tensile force of 4-7 megapascals to protect professional sports.
High end landscape trail/rooftop terrace: solves the problem of discoloration and odor caused by high temperature exposure, resulting in complaints from neighbors, and the color lasts as long as new.
Comprehensive customization service: We are well aware of the differentiated needs of each project, and our company supports deep customization of various colors, sizes (particle sizes). Whether you need extremely fine surface granules. or specific Pantone colored landscape granules., we can perfectly match them with flexible minimum order quantities, completely breaking the industry's conventional limitations.
Project Background: A kindergarten in a certain city in Australia had a regular EPDM plastic activity area that, after being put into use for a year, emitted a severe pungent odor during high temperatures in summer, leading to multiple joint complaints from parents. The kindergarten was forced to launch an emergency renovation project in July of that year.
Challenge: The construction period is in the midst of summer, and it is required that the new site must be "absolutely odorless and environmentally friendly". Due to the construction period limitation, it must be completed and put into use within 10 days, which is almost impossible for traditional materials to accomplish.
Solution: After rigorous selection by the engineering department of the park, our customized food grade sulfur free EPDM granules. (customized particle size: 1-3mm surface layer+2-4mm bottom layer, customized color scheme: Morandi color scheme) were ultimately adopted.
Implementation effect and feedback:
Ready to use, zero odor: On the second day of construction, under the high temperature of 35 ℃ outdoors, there was no odor on site, and it successfully passed the indoor air quality and harmful substance testing of a third-party organization. The park was opened 7 days in advance.
Stunning physical performance: According to the feedback from the principal, the foot feel of the new venue is significantly softer and more solid than the old venue, and the rate of children picking up bags after falling has significantly decreased (thanks to the high tensile and elastic force of 4-7 megapascals).
Long term value verification: The site has gone through three scorching summers so far, and the color is still bright without fading, without any sticking or powdering phenomenon. The park side used it as a benchmark case and designated the purchase of our sulfur free EPDM granules. in the construction of three other new parks under the group.
Over 25 years of industry experience: Deeply involved in the field of rubber granules, witnessing and leading the technological iteration of the industry, with rich experience.
