材料优点
①硬度范围广,脚轮适用材料硬度为55-95A,可依据企业的需求定制。(通常企业选用硬度65-85A);
②承载力良好,可承载400kg以下货物,适用于童车、超市购物车、医院手推车、一般工业用脚轮等;
③良好的减震性能;
④耐磨性优越;
⑤有较好的耐uv、耐化学性能;
⑥脚轮骨架一般以pp材料为主,而tpr脚轮料能与pp完美粘结;
⑦tpr料同样能做出与tpe脚轮料相似的静音脚轮,非常适用于医院推车以及部分需静音场合使用的脚轮;
⑧环保无毒,这也是这种材料非常大的一个优势所在,材料加工过程中不添加有毒助剂,产品不挥发有毒颗粒分子,并且tpr脚轮在运行过程中,不会产生橡胶脚轮的碳黑印。旧品能够回收利用。
