EPDM Compounds for Diffusers

EPDM Compounds: Innovations at WTE

Unveiling the Future of EPDM Compounds: Innovation and Sustainability in WTE’s Advanced Membranes and Eco-Friendly Diffusers

Understanding EPDM Compounds requires scrutinizing various factors including the compound formulation, vulcanization process, mechanical characteristics of EPDM, chemical compatibility with treated liquids, and the durability of mechanical properties.
1. EPDM Compounds Formulation from WTE
Formulation is key to achieving optimal EPDM compound properties. Component selection, such as elastomers, vulcanizers, additives, and fillers, influences the rubber’s final performance. At WTE, we have formulated a specific compound that minimizes plasticizer migration and retains its original dimensions over time, ensuring reliability, durability, and optimal performance.
2. Vulcanization Process of EPDM
Vulcanization, the cross-linking process of polymer molecules, determines the mechanical stability of the rubber. At WTE, we use peroxide vulcanization, which provides better heat resistance and preserves the mechanical characteristics of the membrane over time. Read more here.
3. Expected Lifespan of WTE’s EPDM Membrane
The lifespan of an EPDM membrane depends on various factors such as the nature of the treated liquid, the air flow per diffuser, and the temperature of the air and liquid. At WTE, we have seen EPDM membrane diffusers replaced between 8 to 10 years after installation.
4. Polypropylene Body of WTE Diffuser
The diffuser’s membrane support and retainer ring are made from polypropylene reinforced with 30% glass fiber, improving dimensional stability and mechanical resistance.
5. Eco-friendly Diffusers at WTE
Considering the recyclability of diffusers and reduction of harmful microplastics are essential aspects of diffuser design at WTE. Our diffusers separate the rubber from the plastic for recycling and do not use PFAS-based protective surfaces such as PTFE, reducing potential environmental impact.
6. Manufacturing of WTE’s Membranes in the “Rubber Valley”
Situated in the renowned “Rubber Valley”, we produce EPDM membranes in collaboration with local compound suppliers and membrane molders, allowing us to respond promptly to customer needs.
