The following is said by the elastic sponge bouncing ball manufacturers. Sponge rubber is a porous elastic material, usually known asOf the foam rubber, foam rubber or microporous rubber, it has a hole structure is the general term for a variety of rubber. Sponge rubberVariety, a variety of classification methods, there are soft foam, rigid foam, micro-bubble foam, conductive sea Cotton, magnetic sponge, water expansion foam, composite sponges, compared with the solid rubber, sponge rubber, because of its structural Specificity, that is porous, it has a variety of valuable properties, such as: apparent density is small, light weight material Province, rich in Elasticity and softness, with excellent dust, water, gas and other seal; improved insulation, has a lower conductivity Heat transfer coefficient, increased ability to absorb shock loads, have excellent cushioning shock absorption performance, improved sound insulation, sound-absorbing effect.Improved touch and improve the comfort, physical performance changes over large areas, depending on the density or change the availability of corresponding properties of cell structure Sponge rubber. According to the understanding of elastic foam bouncy ball manufacturers are widely used in sealing, shock absorption, insulation, sound insulation, India Pollution as well as many other aspects of ion exchange in the aerospace, automotive, instruments, meters, appliances and packaging industry plays a wide Pan application. Its shape has plate, strip, tubular, roller, washer, etc., many specifications and shapes. Different Conditions of use, require a different structure and pore size of the hole. To this end, requiring the formulation and processing technology for Adjusted to achieve the corresponding performance.
