1.Protective When you exercise,the protective properties of the mat can keep you in a safe space.In the event of an accident,the mat can often absorb some of the damage,thereby reducing the extent of injury to people. 2.Cushioning The mat must have a certain degree of cushioning to prevent damage to the floor caused by too much force,and to prevent…
The effectiveness of sound deadening mat largely depends on their material.Some common materials used in sound deadening mat include: 1.Sound deadening rubber mat:They have good elasticity and sound-absorbing effect for high-frequency sounds,and also have antibacterial properties and thermal insulation.They distribute stress evenly under load,have stable performance,are resistant to corrosion,oil,organic solvents,radiation,and have a long service life. 2.Foam damping and sound-absorbing…
The thickness of an mat for sport should be chosen based on the specific sport and individual needs. For sports such as yoga that require stable support and balance,the thickness of the mat is crucial.Beginners may be better off with a thicker mat to reduce the risk of injury,while professional practitioners may prefer a thinner mat to enhance their…
Neoprene rubber pad is a sheet material made of neoprene rubber as the main material, which is made by mixing, plasticizing, and vulcanizing various processes. Neoprene rubber pad has the characteristics of being resistant to oil, heat, acid and alkali. It also has high tensile strength and elongation. The physical properties of neoprene rubber pad are stable and it…
