The performance and complexity of electrical/electronic components are rapidly increasing – and so is the importance of control cabinets. They serve as control centers in which electronic components of machines and systems are protected from moisture, dirt, heat, and cold. For this challenging task, RAMPF Polymer Solutions has developed high-performance sealing foams consisting of PU and SIL systems. The two component materials are UL50 and UL 508 listed and meet the IP ratings (IP 67 and IP68).
