豪沃橡塑高密度聚乙烯介绍:
【基本特性】高密度聚乙烯是一种不透明白色腊状材料，比重比水轻，比重为0.941~0.960，柔软而且有韧性，但比LDPE略硬，也略能伸长，无毒，无味。
【燃烧特性】易燃，离火后能继续燃烧，火焰上端呈黄色，下端呈蓝色，燃烧时会熔融，有液体滴落，无黑烟冒出，同时，发出石蜡燃烧时发出的气味。
【主要优点】耐酸碱，耐有机溶剂，电绝缘性优良，低温时，仍能保持一定的韧性。表面硬度，拉伸强度，刚性等机械强度都高于LDPE，接近于PP，比PP韧，但表面光洁度不如PP。
HOWO rubber high density polyethylene introduction:
[basic characteristics] HDPE is an opaque white waxy material, with a specific gravity of 0.941 ~ 0.960, which is lighter than water. It is soft and tough, but slightly harder than LDPE, and also slightly elongated. It is non-toxic and tasteless.
[Combustion Characteristics] it is flammable and can continue to burn after leaving the fire. The upper end of the flame is yellow and the lower end is blue. It will melt during combustion, with liquid dripping and no black smoke. At the same time, it emits the smell of paraffin burning.
[main advantages] acid and alkali resistance, organic solvent resistance, excellent electrical insulation, and certain toughness at low temperature. The surface hardness, tensile strength, rigidity and other mechanical strength are higher than LDPE, close to PP, and tougher than PP, but the surface finish is not as good as PP.
