Description

Technical Field

[0002] Polyurethane film, also known as PU film, is an environmentally friendly material. It boasts excellent elasticity and high lightweight. Despite its extremely thin thickness (0.012-0.035mm), it exhibits unparalleled waterproof properties compared to other materials (withstanding water pressure exceeding 10,000 mm water column). Utilizing advanced technology to incorporate hydrophilic agents, the film not only possesses high waterproof performance but also excellent moisture permeability (human sweat can freely penetrate the film). This functional breakthrough, combined with lamination processing technology in the textile industry, significantly enhances the added value of textiles. During the production of polyurethane film, heat dissipation of the masterbatch is often required for processing and production. Therefore, a cooling device for the anti-stick masterbatch in polyurethane film production is needed.
