Cross-linked polyolefin foam material is a very good floor impact sound of the buffer material, non-absorbent material has a very good chemical resistance, hydrophilicity and other characteristics, can prevent the cracking and sinking warm kang. In addition, no maintenance service and excellent durability can be semi-permanent use. By the high
elasticity of lightweight foam to reduce the impact of sound particles, but also because it is independent of the bubble material with lower thermal conductivity of insulation is excellent. Finding and processing this material easy and simple construction is widely used.
