Foam shoe material sector to maintain astable output

   It is understood that the foam shoe material industry is the traditionaldownstream industry of EVA, which has maintained steady growth in the past twoyears. With the level of consumption, health consciousness, professional sportsfootwear industry booming, downstream shoe material consumption has alwaysmaintained good growth momentum. EVA foam is mainly used in the midsole andinsole of shoes, it can be said that EVA is the past 30 years has triggered arevolution in the shoe industry foam shoe materials.

   EVA foam is EVA (ethylene - vinyl acetate copolymer) and low-densitypolyethylene as raw materials, and add other additives after molding foam orinjection foam made of foam. With good flexibility, rubber-like elasticity,transparency and surface gloss are relatively good, good chemical stability,anti-aging and ozone strength, non-toxic. As a shoe material, the overallperformance of a certain degree of softness and high elasticity.

   EVA foam formulation in the shoe industry, generally using in-mold foam,EVA granulation material into the foam mold, high temperature and pressure tolet it foam. By foaming EVA can make the sole lighter, and has a certainelasticity of EVA resin so that the sole has a proper cushioning function, sothat EVA foam shoe materials for most casual shoes and jogging shoes needs.

   However, the aging resistance, flex resistance, elasticity and wearresistance of EVA foam are poor, limiting its use to a certain extent. Inrecent years, the rise of ETPU and sample control, EVA foam shoe material alsoput forward a lower hardness, higher resilience, low compression deformationand other new performance requirements, so EVA foam shoe material and othermaterials mixed and modified with the current shoe manufacturers have become apopular research. Due to the price advantage of EVA foam material, it willremain the main material choice for popular sports shoes for a long time tocome.

    Arough assessment, the future of China's foam footwear industry to EVA consumption to maintain a growth rate of about 9%, is expected to 2025, China'sEVA in the field of foam footwear consumption will be close to the total sizeof about 1 million tons, belonging to the EVA second largest downstreamconsumer market.
