        MD, EVA

        MD: MODEL or PHYLON飞龙 统称;PHYLON: 俗称飞龙, is types shoe sole material, generally made use in 底, use add hot pressure shrink EVA foaming made formed mixed combined material 质(EVA二次 high pressure molding product), features light, elastic property and resistant property can good, hardness is foaming temperature degree control.

        EVA: Ethylene Vinyl Acetate- ethylene resin acid fiber. light has elastic property chemical combined formed material 质, large material, more and RB联姻出卖, price use material how much. another add upper combined 手工费, water 费, more 20 large 毛. composite/compounding material use to it, is foaming, price can 忽略, factory cost 肯定会 add upper.

         therefore, MD shoe sole 里面一定都含 has EVA, MD底也叫PHYLON底. ratio 如MD=EVA+RB or 者EVA+RB+TPR also has 一 鞋 is RB+PU and other.

        RB, TPU

        RB: Rubber, 即橡胶. RB shoe sole wear resistance 佳, shrinkage stability, bending property good, 但材质 heavy, generally used for outer 底.

        TPU: large more use in shoe sole upper, especially is upper, can use in parts upper, price relatively 贵, TPU separation is 天然橡胶 and combined formed 橡胶, 天然橡胶 main/primary 源于三叶橡胶树, combined formed is 由人工 combined formed methods, using/adopting different raw materials (mono 体) combined formed different types type 橡胶, 顺丁橡胶 and 丁苯橡胶 is output/production volume most large general purpose combined formed 橡胶.

        PU, PVC

        PU: Polyurethane, is polymer/macromolecule polyurethane combined formed material, PU就 is material, types type very more, 帮面材 material. 论码卖, has has 便宜, basic 不贵, has PU底, outer mono relatively less use to 此底. PU is foam large density resistant use material, density, hardness high, wear resistant, elastic property 佳, water property strong/high, easy fracture, easy yellowing. PU常 used for 篮球, 网球鞋 in or rear in 底夹层, can used for 休闲鞋 outer 底.

        PVC: Polyvinylchloride, polyvinyl chloride (PVC), is world upper application types combined formed material. PVC也 is material, product, 不 也 has high 档. large more relatively 便宜, oil resistant, wear resistant, insulation property can good, anti slip property can 差, resistant 寒, resistant 折, gas property 差.

        TPU, TPR, TR

        TPU: Thermoplastic Polyurethane, thermoplastic polyurethane (TPU), is types property polymer/macromolecule material. TPU advantages is elastic property good, 但材质 heavy, can force relatively 差. used for slow 跑, slow 步, 休闲鞋 in 底.

        TPR: Thermoplastic Rubber, thermoplastic property elastomer, thermoplastic property 橡胶. TPR and RB difference, relatively 香, price relatively RB, more, upper lower versus 差5毛. has high strength, high elastic property, also can injection molding processing, tool has environmental protection 无毒, hardness scope/range 广, color property excellent 良, soft/flexible, resistant fatigue, resistant temperature property good, processing properties excellent and other more heavy features. can injection molding, can mono molding, wear resistance relatively 差.

        TR: TPE and combined formed material, tool has appearance more, good, color 泽艳, light degree high, technology content high and other features, but also can 100% recycling, belongs to environmental protection type shoe sole material.

        材 material shoe sole and features

         about/regarding PU, PVC, TPR, TR, RUBBER and other 识别:

        PU is most light most wear resistant, PU材 material shoe sole very good 认, in very light, shoe sole 背面 孔都 is 圆. PVC material shoe sole in ratio TPR need heavy. TPR材 material shoe sole elastic property ratio PVC need good, shoe sole 自然掉落 lower, if can elastic 起 话就 is TPR, PVC材 material shoe sole relatively TPR need 便宜, is quality good, especially is in 冬天, very easy 断底. PVC材 material shoe sole has features is has injection 孔, has odor, time long also long white 东西. TR shoe sole surface very light 亮, ratio generally TPR shoe sole need hard 一, TR injection ratio TPR more, injection very especially.

         weight upper: RUBBER(橡胶) most heavy, PU, EVA most light;材 material upper: PU贵, EVA, TPR适 in, PVC most 便宜; process upper: TPR做出 就 is molding, 而PVC need processing, ABS generally is high 跟鞋 材 material, and hard; application upper: PVC more use in material or non weight 部位, or is manufacturing 童鞋;PU革则 can suitable for type material or weight 部位. in bag 方面, suitable comparison more is PVC革. this is is bag in material product different in 鞋里 脚, dispersion hot gas;不 use 承受 人 体 heavy.

        PU, PVC difference methods comparison easy, from 边角看PU need ratio PVC thick many, 手感方面也 has difference, PU soft/flexible 一;PVC relatively hard 一;也 can use 火 烧, PU ratio PVC need very more.
