Do you know how to make medical film materials? I came to popularize relevant knowledge for my friends.
Medical film material, the main body of the plastic used is polyvinyl chloride resin, and appropriate plasticizer and other additives are added. The weight content of each component is 100 parts of polyvinyl chloride resin, 20~25 parts of dihexyl phthalate, 10-15 parts of dioctyl adipate, 1-5 parts of acetyl citrate, 0~20 parts of epoxy dioctyl tetrahydrophthalate, 2~10 parts of epoxy soybean oil 1-5 parts of ethylene vinyl acetate copolymer, 0.5~1 parts of stearate, 0.1~0.5 parts of benzyl silicone oil as lubricant. The above components are mixed, granulated and calendered to form a film material with a thickness of 0.35-0.45mm. The formula is reasonable, with good elasticity, soft and transparent film material, good permeability, good thermal stability and low temperature resistance.
The content shared by the medical pu film editor today is a little short. Next time, try to find more relevant information to share with you.
