APPLICATION OF WASHERS BONDED WITH EPDM RUBBER
Washer with EPDM gasket structurally consists of two elements - steel washer and gasket made of ethylene propylene diene monomer, one of the types of synthetic weather-resistant durable rubber EPDM, which has high elasticity and stable consistency during pressing.
The advantages of using weather-resistant rubber EPDM as a sealing gasket are indisputable in comparison with simple rubber:
The EPDM gasket is firmly anchored to the steel washer by vulcanizing. The steel part of the washer has an annular shape and is slightly concave, which allows the fastener to adhere securely to the base surface and not to spoil the substrate.
Such washers are designed to strengthen and seal the fixing unit. Bonded washers are the cost-effective solution for roofing screw connection. The most common area of application - the attachment of roll and sheet materials for external, such as roofing, work.
