EPDM Sealing washers for Sheet Metal Screws
Q.What is EPDM washer screws?
A.Hex Washer Head EPDM Rubber Roofing Screws
The EPDM rubber attached to these screws acts as a barrier preventing leaking from occuring near the screw head. The integral washer also distributes pressure over a wider surface area to prevent damage during installation.
A.EPDM (ethylene propylene diene monomer) : A popular Elastomer for outdoor Applications where weather and water resistance is required. EPDM offers a Superior resistance to Ozone, UV and sunlight. It also has a good resistance to steam and brake fluid.
EPDM Bonded sealing washers. These are generally used with sheet metal screws (Self-Drilling or Self-Tapping) to seal out air and water or to dampen noise and vibration.
These are made with EPDM (style 40 EPDM Sheet).
EPDM washers are generally regarded as far superior to Neoprene (Neo Bond) washers in situations that do not involve chemical or oil environments.
Q.Is EPDM the same as rubber?
A.Ethylene Propylene Diene Monomer (EPDM) is a synthetic rubber. It is made from propylene, ethylene, and diene comonomer. Its standout feature is that it is highly resistant to weathering and so can be used for sealing.
Q.How long does EPDM rubber last?
An EPDM rubber roof is incredibly long-lasting and durable. The rubber recycled and used for the synthetic rubber membrane isn't damaged under the sun's UV or ultraviolet rays. If installed correctly, you can expect a rubber roof to in excess of up to 50 years.
