Preparation and application of dynamic non-wicking PU foam

A dynamic non-wicking polyurethane (PU) foam, wherein the dynamic non-wicking polyurethane (PU) foam is prepared from the following components by weight percentage on the basis of the total dynamic non-wicking polyurethane (PU) foam:

• Polyether polyol:
• 62.6-75.4%,
• Diisocyanate:
• 15.9-26.2%,
• Dynamic non-wicking additive:
• 5.6-7.2%, and
• Auxiliary agent:
• 3.1-4.0%;
• wherein the dynamic non-wicking additive is one of (i) carboxylic acids, (ii) amines or (iii) alkyl alcohols, or (iv) is composed of carboxylic acids, amines, and alkyl alcohols in any proportion, wherein the carboxylic acids and the amines contain alkyl groups having a total of 8-20 carbon atoms, and the alkyl alcohols contain alkyl groups having a total of 11-20 carbon atoms;
• and
• the auxiliary agent is composed of the following components by weight percentage on the basis of the total auxiliary agent:
• Silicone surfactant:
• 18.8-33.2%,
• Amine promoter:
• 3.1-7.6%,
• Tin catalyst:
• 3.2-7.3%,
