EPE pearl cotton has good characteristics, softness and cushioning. Low thermal conductivity and good thermal insulation. The foam material with independent bubbles has almost no water-absorbing and waterproof material. A corrosion-resistant material which can not be corrode by various drugs. The machinability of fracture, adhesion, extrusion, vacuum molding and compression molding is excellent. The foam material has fine bubbles, smooth appearance, colorability and beautiful effect. EPE pearl cotton coating machine is a kind of coating machine developed for coating hot sol on pearl cotton in a large area, which is convenient to use and has high efficiency. Therefore, it is widely used and generally easy to buy in the market. EPE pearl cotton, also known as polyethylene foam cotton, is a non-crosslinked closed-cell structure. It is also a new type of environmental protection packaging material at present, which is mainly composed of countless independent bubbles produced by physical foaming of low density polyethylene. It has many advantages such as waterproof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance and so on, and also has good chemical resistance.
