rubber expansion joints are molded and vulcanized in hydraulic presses. This high pressure process produces a smooth finished product with outstanding adhesion between the cover,
reinforcement and tube.Most of our competitors still use Natural Rubber impregnated Nylon tire cord between sulfur cured, EPDM covers and tubes. This construction becomes brittle
with age at higher temperatures, so we changed from Nylon to Kevlar®, as Kevlar® has a higher modulus thatminimizes swell and elongation, and outstanding temperature tolerance
up to 250°F (121°C).Changing the EPDM curing system from sulfur to the slower, more expensive peroxide method raised the high temperature safety factor, as well as other physical
properties. We force EPDM between, over and under the Kevlar® cords. This makes Safeflex superior as cover, reinforcement and tube are all homogeneous. Natural Rubber has been
completely eliminated to improve aging and temperature tolerance.Another serious problem had been the body pulling out of the flange because flexible bead wire does not provide
sufficient retention. Our answer was to wrap the tire cord around a solid steel ring in place of the cable. In 20 years, the steel ring has never pulled through.Sealing pressure is amplified by the ductile iron flanges that rotate inward around solid exterior stops. The split flanges are hooked together to prevent spreading.rubber expansion joints was
the culmination of 25 years of application experience and a driving desire to eliminate all possible failures. These improvements were costly, but the engineering and contractingcommunities and the consumers they serve have always been receptive to our improved longer lasting and safer products. Why risk failure when there is a better product and the cost difference is meaningless against safe extended life. Water burst and leakage failures are catastrophic in downtime and property damage as sometimes they come close to being waterfalls.
