Характеристики
LV DU high-end rubber foam insulation materials which has introduced advanced foreign technologies and processes. After scientific research and development、technological innovation, adopting excellent performance of nitrile rubber and polyvinyl chloride as the main raw materials, and adopting Shenzhou particular "vacuum microcrystalline" foaming Technology (Vacuum Microcrystal Foaming Technique abbreviated as VMFT), made by precise control of micro-foaming. The cells are dense and high closed cell rate.
