Comparison of Odor between Sulfur Free EPDM And Ordinary EPDM

There are essential differences in odor performance between sulfur free EPDM and ordinary EPDM. Ordinary EPDM, due to the traditional sulfur vulcanization process, is prone to release sulfur-containing compounds under high temperature or strong ultraviolet radiation, resulting in a pungent odor; And sulfur free EPDM fundamentally eliminates the generation of sulfuric acid and sulfides through sulfur free crosslinking technology, achieving true odorlessness. This odor difference is not only related to the user experience, but also directly affects the applicability and environmental compliance of the product in sensitive scenarios such as children's playgrounds and indoor venues.

Addressing core user needs and challenges

As a professional manufacturer, we are well aware of the challenges you will face in project implementation. Our sulfur free EPDM granules are designed to solve problems such as odor problems, short service life, easy fading and aging, and difficulty in meeting environmental standards. Whether it's strict indoor air quality requirements or performance degradation in extreme outdoor weather conditions, our products can provide durable, safe, and aesthetically pleasing solutions, making your site construction more worry free and compliant.

Deep comparison of odor and performance between sulfur free EPDM and ordinary EPDM

From the perspective of materials science and production technology, sulfur free EPDM has achieved comprehensive surpassing of ordinary EPDM in multiple dimensions:

Odor and environmental friendliness: The sulfur vulcanization system of ordinary EPDM will decompose into sulfur-containing gases during the aging process, producing odors; Our sulfur free EPDM granules do not contain sulfur components and will not decompose into sulfuric acid under high temperature and strong ultraviolet radiation, truly achieving odorlessness and meeting food grade hygiene standards, extremely environmentally friendly.

Molecular structure and service life: Thanks to sulfur free technology, the molecular structure of the product is more stable, the anti-aging performance has been greatly improved, and the service life of the product is more than three times that of ordinary products.

Physical and mechanical properties: The elasticity and tensile strength of the product are increased by 2-3 times, and the tensile strength can reach 4-7 megapascals; At the same time, the product performance retention rate is increased by more than 5 times, ensuring that the site maintains excellent buffering and rebound performance for a long time.

Weather resistance and appearance performance: The product has more antioxidant function, brighter color and less likely to change color, and better high temperature resistance. In addition, the low granule packing density and strong three-dimensional sense of edges not only enhance the aesthetics, but also strengthen the adhesion with the glue.

Customer application case (anonymous):

A high-end bilingual kindergarten in a coastal city once faced serious challenges in venue renovation. The original ordinary EPDM site emitted a pungent odor under high temperature exposure in summer, and severe fading and powdering occurred in less than two years, with continuous complaints from parents. After the overall renovation using our sulfur free EPDM granules, the site not only completely eliminated odor hazards, but also passed the rigorous indoor air quality testing smoothly. Its bright rainbow color scheme remained as bright as new after three years of sea breeze and strong ultraviolet testing. The principal provided feedback that the flexibility of the venue is still excellent, and the safety of children's activities on it has been greatly guaranteed, completely solving the previous problems of aging and environmental protection of the venue.
