Grafenberg, Germany - The RAMPF Group, including RAMPF Dosiertechnik and RAMPF Giessharze, has combined patents for machine and material technology to launch PU foams with elastomers skin under the Raku-Skin brand name.
The patent for the dispensing technology was acquired by RAMPF Dosiertechnik many years ago, the 24 June statement said, whereas the materials patent came with the late acquisition of the seals division of CHEMQUE, based in Ontario, Canada.
"With the combination of patents, there will be no limitations to the possible applications," said Klaus Schamel, managing director of RAMPF, in the statement.
According to RAMPF, the mixing and dispensing system produces a foam core with a "co-axial" elastomer skin, which is applied directly to the component using the FiPFG (Foam in Place Foam Gasket) process. Immediately after application, foam formation and hardening of the core begin, as well as cross-linking of the elastomer skin, the statement said. RAMPF said the foam core can be adapted individually in hard-ness and density to match the application.
The sealing foams were designed for sensitive applications such as electrical housing, household appliances and automotive applications. (RD)
