Pipe clamps with noise absorbing blocks for ping use a new TPE compound

30-Aug-08

Minnesota-based RTP Company, a global leader in specialty thermoplastic compounding has supplied its RTP 2700 Series styrenic-based TPE (Thermoplastic Elastomer) to Sioux Chief Manufacturing for developing a series of universal pipe clamps with noise absorbing blocks to lessen the noise transfer caused by loose pipes. The clamp lowers down noise transferred in the pipe by holding the pipe away from the building structure and isolating the pipe from the metal bracket, cutting any possibility of galvanic corrosion that occurs when two dissimilar metals are in contact. The TPE inserts fit into the bridge and base of the Touchdown clamp. As they are softer than the adjoining nylon material they provide a higher degree of protection against noise transfer. Both Uniform Plumbing Code (UPAC) and International Plumbing Code (IPC) recommend pipes to be safely fastened to the supporting structure in various increments, depending on pipe or tube diameter. RTP Company engineers recommended an RTP 2700 Series styrenic-based TPE for the clamp's insert. The compound offers elasticity comparable to rubber, a Shore A hardness of 70 and meets strength and compression set requirements when installed around a pipe.
