The invention relates to a novel migration-resistant PVC sealing material and application thereof. The PVC sealing material is prepared from, by weight, 40-50 parts of PVC resin, 20-40 parts of a plasticizer, 10-25 parts of filler, 1-5 parts of a stabilizer and 2-10 parts of a microsphere modifier. The sealing material not only has excellent migration resistance and low temperature resistance, butalso has excellent mechanical properties and good resilience, and ensures good sealing of refrigeration equipment such as refrigerators and the like; and meanwhile, the price is relatively low, costcontrol is facilitated, and the sealing strip is very suitable for being widely popularized as a refrigeration equipment sealing strip.
