A parts manufacturer requested a new seal design to help eliminate under-hood noise. The seal was vitally important to the engine cooling system, which helps regulate the engine temperature and ensures optimum performance.
For a commercial door application, a company requested a seal that could slide into a channel, while also possessing great compression properties, durability, weatherability and high temperature resistance.
To prevent water penetration between a headlight housing cap and the body, the customer explored both EPDM and silicone options. The company ultimately selected a sponge-silicone specifically formulated for the application by Lauren’s R&D team.
Lauren's roof mount pad was designed completely out of EPDM, due to its excellent UV ozone and weathering properties. Our engineers determined the proper combination of EPDM sponge and dense material needed for anti-slip properties and durability.
This closed-cell EPDM improves upon the appearance and performance of similar materials. While initially designed to improve an automotive door skin, this material could enhance sealing performance in industries such as HVAC, containers, construction and other markets where excellent compression, weathering and aesthetic qualities are required.
Plastic extrusion added for faster gasket assembly
Rather than adhesives, a dual-durometer plastic extrusion was used to more efficiently attach a silicone gasket to a component. By using a mechanical connection, the manufacturer was able to take advantage of silicone's performance properties.
