Application of anti-aging technology in shoe materials
The effects of different anti-aging additives on the aging chromaticity of different thermoplastic elastomers including thermoplastic polyurethane(TPU),styrene-butadiene-styrene block copolymer(SBS)and polyvinyl vinyl(PVC)were researched.The results demonstrated that light stabilizer RIASORB UV-234 had best initial color and anti-light aging discoloration of TPU shoe material.For SBS shoe material,it was found that U-pack B7067 with good anti-thermal oxygen aging and light aging was best.For PVC shoe material,the results showed that the composite light stabilizer U-pack UV-7917 had obvious anti-aging degradation effect and the best weather resistance.All these studies research could provide reference for the selection of anti-aging additives for production and processing enterprises.
