摘要（英）：

The invention relates to a heat-shrinkable tubing for refrigeration. The heat-shrinkable tubing comprises the components of polyethylene, ethylene-vinyl acetate copolymer, compatilizer, magnesium hydroxide, lubricant, antioxidant and masterbatch. The heat-shrinkable tubing for refrigeration is characterized in that the weight percentages of polyethylene, ethylene-vinyl acetate copolymer, compatilizer, magnesium hydroxide, lubricant, antioxidant and masterbatch are 5%-45%, 5%-45%, 0.4%-4%, 40%-55%, 0.5%-1.5%, 0.3%-1% and 1%-4% respectively. The prepared heat-shrinkable tubing for refrigerationhas common raw materials and low cost and is suitable for industrial production; and in the production, storage and use of the heat-shrinkable tubing, the environment can not be polluted and the heat-shrinkable tubing is harmless for human body and can not generate harmful gases when burnt.
