河北联兴聚氨酯胶辊是指用聚氨酯材料包覆铁芯制作的橡胶辊，按原材料种类分为聚酯型、聚醚型和聚己内脂型，总体性能介于橡胶和塑料之间，生产工艺以浇铸型为主，联兴聚氨酯胶辊具有优良的物理性能，抗老化性能好，耐撕裂性、回弹性、耐磨性均优越，抗压和耐磨性能是天然橡胶的3-5倍，同等工作环境下使用寿命是普通胶辊的3倍左右，硬度范围HSA15-HSD80。聚氨酯胶辊应用行业极其广泛，如粮食加工行业、印刷行业、钢铁行业、涂装行业、塑料行业、矿山行业等等都得到了应用。

Hebei Lianxing polyurethane roller is a rubber roller made of polyurethane material coated with iron core. It is divided into polyester, polyether and polycaprolactone types according to the raw materials. The overall performance is between rubber and plastics, and the production process is mainly cast type. Lianxing polyurethane cots have excellent physical properties, good aging resistance, tear resistance, resilience and abrasion resistance. The compression and wear resistance are 3-5 times of that of natural rubber, and the service life is about 3 times of that of ordinary rubber cots under the same working environment. The hardness range is hsa15-hsd80. Polyurethane cots are widely used in many industries, such as grain processing industry, printing industry, steel industry, coating industry, plastic industry, mining industry and so on.
