Rubber rollers are used because rubber has an elasticity that no metal can provide. Metal can corrode, scratch, dent and crack, which can happen easily and often. Additionally, the texture and hardness of metals can scratch and damage any medium they come into contact with. Other materials, such as fiber-reinforced composites, can offer better quality, but are more expensive and less readily available. They are not readily available and are usually more expensive. Rubber pulleys are the most economical method while offering longer pulley life and unique physical and psychomechanical properties Silicone Roller,Acid Resistance Roll,Textile Printing Roller,Wear Resistance Roll Taixing Jinlong Rubber Rollers Co., Ltd. , https://www.txjinlongrubber.com
