rubber band
The material used for the rubber ring is required to have good elasticity, low friction coefficient, resistance to medium corrosion, dissolution and swelling, aging resistance, small permanent deformation after compression and long-term work, and non-stickiness when used under high temperature 2. It does not lose its elasticity at low temperature and has a certain strength and compression resistance. Therefore, under normal circumstances, the rubber ring mostly uses nitrile rubber, and fluororubber, silicone rubber, hydrogenated nitrile rubber, etc. can also be selected.
