These Pads are moulded in Natural Rubber or Standard Neoprene or Bridge Bearing Neoprene. Those made in Natural rubber provides maximum resilience and vibration isolation and those made in standard neoprene provides longer life and moderate oil resistance. For maximum life as well as excellent oil resistance and resilience very near to those made of Natural Rubber, Bridge Bearing Neoprene Super Waffle Pads are advised.
