上海力强四孔鞋/四孔鞋厂家

SPU-Super PU，是上海力强公司投入大量资金、人力、物力经过一年的努力研制而成的最新产品。本公司自主研发，拥有其全部自主知识产权和制造技术。SPU技术通过消化和引进国外最新鞋业制造技术及化学配方，以PVC，橡胶为主材并配以十几种化工原料配制而成。在制造工艺中，采用独特的气体动力学和气相保护学原理，通过气密型极佳的金属密封模具，高压成型。通过这种独有的技术，SPU鞋底具有极其轻便柔软，表面细腻如膏，回弹力好等特点，在许多性能上都超过了PU。特别是通过分子膨胀原理使得抗静电剂均匀的融入鞋底，使得防静电指标的稳定性均大幅好于PU鞋，但材料成本确远远小于PU材料。SPU鞋底的制造技术、配方工艺、生产工艺是目前防静电鞋行业科技含量最高，制造工艺最复杂和性价比最高的产品之一，也是未来最有发展前景的防静电鞋业产品。

SPU-Super PU is the latest product whichShanghai LiQiangcompany has invested substantial funds, human and material resources through efforts of one year in developing. The company researches it independently, with all of its proprietary intellectual property and manufacturing technology. SPU technology is prepared using PVC and rubber as principal material and dozens of chemical raw materials by means of absorption and importation of foreign latest shoes manufacturing technology and chemical formulations. In the process of manufacturing, it is formed by high pressure by means of metal seal mold with excellent airtight, adopting unique gas dynamics and gas protection principles. By this unique technology, SPU sole is very light and soft, exquisite as paste for surface and good resilient and other features which are more than PU in many performance. Particularly, its material costs are much smaller than the PU material by integrating antistatic agent into the sole according to the principle of expansion of molecular which makes the stability of anti-static index be significantly better than PU shoes. SPU shoe is one of products, with the highest content in technology, the most complexity in manufacturing process and the highest co-effective for manufacturing technology, formulation technology and production technology in anti-static shoes recently, and is the most promising anti-static footwear product in the future.
