Attention customers struggling with "high-temperature" manhole gaskets!

On November 1, 2015, the "RCF regulation" was implemented, which essentially prohibits the use of sealants made from ceramic fibers. The commonly used alternative is "biodegradable fibers." Several years have passed since similar products have been released by other manufacturers, but we have recently been hearing feedback from job sites such as the following: "The material is weak during installation." "When the lid is opened, it crumbles." The MacThermo Bio-HD series is a product that has been reinforced by knitting each weak thread with metal wire, making it stronger than previous versions. It has already been successfully used in coke ovens at steel mills, so please check the details below!
