There are many kinds of cosmetic hose materials, among which TPU is widely used in terms of comprehensive performance, and its price and performance are superior. TPU is a kind of polymer material between rubber and plastic, named thermoplastic polyurethane elastomer rubber. TPU hardness, wear resistance, oil resistance, transparency, elasticity and other properties can meet the requirements of cosmetic hose packaging materials, and are widely used in daily necessities, sporting goods, toys, decorative materials and other fields.
1. The weather resistance of TPU is better than natural rubber and other synthetic rubber. Its anti-ozone and anti-radiation properties have special applications in the aerospace industry;
2. Oil resistance: The oil resistance of TPU is better than that of NBR, and the oil resistance life is excellent;
3. Excellent abrasion resistance: Its Taber abrasion value is 0.35-0.5mg, which is the smallest among plastics. Adding lubricant can reduce friction and further improve wear resistance;
4. Tensile strength and elongation rate: the tensile strength of TPU is 2-3 times that of natural rubber and synthetic rubber, the tensile strength of polyester TPU is 60MPa, and the elongation is 410%; the tensile strength of polyurethane TPU 50MPa, elongation 550%;
5. Hardness range: TPU hardness is 10a-80d, and it has similar compression deformation characteristics below 15A. When the hardness is greater than 85A, it still maintains elasticity, which is a characteristic that other elastomers do not have. Therefore, TPU has high load carrying capacity and good suction and discharge effect;
6. Food, medicine and hygiene: TPU has biocompatibility and anticoagulant properties, and medical TPU is more and more widely used. Such as blood vessels, ureters, infusion tubes. TPU is widely used in the food industry because of no enhancer, non-toxic and tasteless;
