PT-MAT Feature Easy Installation Reduces Soundproofing Requirements Many Uses Just cut off the required amount and install it. Can be used as isolation for equipment or plumbing support, wherever noise reduction is required. The pads can be used for impact load dissipation, vibration absorption, and reduction of movement during earthquakes, depending on the type of PT Mat and the pad's shape. Applications ●Vibration reduction for pumps, packaging machinery, etc. ● Isolating pipes from their supports PT-MAT Concrete foundation Equipment base Anchor bolt Rubber bushing PT-MAT Dimensions Reference number Dimensions (mm) Mass kg Structure ※Can be cut to the required size. slit spacing slit spacing ※Other sizes also available Characteristic ) Note : The contents of this catalogue are subject to change without notice.
