RAW MATERIALS OF ROTOMOULDING
线性低密度聚乙烯(LLDPE)是最理想的滚塑原料。LLDPE 是乙烯与丁烯、乙烯等的共聚物,分子呈线型结构,密度为0.93g/cm3。LLDPE用于滚塑的优点在于流动性好、热稳定性好、耐环境应力开裂性好、抗冲击性能好、刚性好。
LLDPE(Low Linear Density Polyethylene)is the ideal raw materials for rotomoulding.LLDPE is the copolymer of polythene,butylenes and so on with the linear molecule and the density of 0.93g/cm3.The advantage of LLDPE is it is better in liquidity,thermal stabilization and ESCR<impact, and hardness.
滚塑所采用的原料一般均为进口,我们采用乐天、美孚为主。除常用的颜色自己配色外,其余最好采用专门色料供应商的原料,如马来西亚 ICO及南京聚隆等,能调配耐强紫外线、抗强氧化性、甚至阻燃等专用料。
Rotational molding of raw materials used in general are imported, we use Le Tian, Mobil. Besides the common color your own color, the best use special pigment suppliers of raw materials, such as the Malaysia ICO and Nanjing Julong, special material blending resistant to ultraviolet, anti oxidation, and flame retardant.
