Exacting molding parameters of the elastomer and its natural properties make Waffle Seal defiant to constant side slipping wear and abrasion.
This tough durable characteristic of Waffle Seal will wear like steel and remain constant over the years of service.
The Ross Flex Test has shown that Waffle Seal completed 100,000 cycles at -40F without any sign of failure.
Chemical resistant is another inherent trait of the seal's composition and design. Waffle Seal is compatible with a wide range of chemicals.
Even aromatic petroleum hydrocarbons succumb to the barrier provided by Waffle Seal. This unique elastomer gives maximum resistance even under periods of direct contact with the stored chemical.*
Our simple design concept, polyurethane formula, and production techniques make the manufacturing of Waffle Seal consistent to our rigid specifications.
We make quality inspections at regular and critical points before, during, and after production runs. Many years of manufacturing integrity go into every product.
Our seal is a polyurethane blown elastomer, compounded to 60 Shore A Durometer for higher strength.
Polyurethane, or simply urethane, was selected because of its durable and broad range of resistive properties. Only urethane, not rubber blends, could fill the bill for the Waffle Seal.
Our composition is polyurethane foamed elastomer, compounded for higher strength, abrasion, and chemical resistance.
Laboratory Tests - Ozone resistance tests on Waffle Seal have proved that it is tough and durable with no signs of cracking.
Simple Design Concept - The overall design of Waffle Seal was kept simple for practical, easy installation, product economy, and minimal maintenance.
Easy to Install - Twenty-five and fifty-foot segments of our seal can be easily bolted onto existing or new floating roof covers without distortion or puckering.
Durable Polyurethane Composition - Waffle Seal is made of polyurethane foamed elastomer, compounded for high strength, abrasion and chemical resistance.
Abrasion Resistant - Our seal defies constant side slipping wear and abrasion from weld seams, rivets, and other internal protrusions. It wears like steel.
Chemical Resistant - Waffle Seal is compatible with many of the industry's chemicals.* This unique elastomer provides maximum resistance even under periods of direct contact with the stored chemicals.
Quality Control - inspections are made at regular and critical points before, during, and after production runs.
State of the Art Manufacturing - Our custom-designed, high pressure machine monitors temperatures, pressures and ratios in real-time to ensure a high-quality seal every time. Our special-purpose molding process creates a polyurethane foam seal with an integral, thick-skin to enhance durability and chemical resistance.
