豪沃橡塑高密度聚乙烯介紹:

　　【基本特性】高密度聚乙烯是一種不透明白色臘狀材料，比重比水輕，比重為0.941~0.960，柔軟而且有韌性，但比LDPE略硬，也略能伸長，無毒，無味。

　　【燃燒特性】易燃，離火后能繼續(xù)燃燒，火焰上端呈黃色，下端呈藍色，燃燒時會熔融，有液體滴落，無黑煙冒出，同時，發(fā)出石蠟燃燒時發(fā)出的氣味。

　　【主要優(yōu)點】耐酸堿，耐有機溶劑，電絕緣性優(yōu)良，低溫時，仍能保持一定的韌性。表面硬度，拉伸強度，剛性等機械強度都高于LDPE，接近于PP，比PP韌，但表面光潔度不如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.
