Silicone material is a kind of high active material, its density has been recognized by the scientific community. The density of silicone rubber material is 0.0012. It can be accurately calculated whether the mass of rubber belt is added with other compounds. The ZD material is softer and the tensile coefficient is stronger. It is recommended to use silicone material for a long time.
