摘要:
A resin fuel tube is provided, which includes at least one resin layer, wherein the resin layer is made of a resin composition comprising: (A) a polypropylene prepared through polymerization with the use of a metallocene catalyst; and (B) a polypropylene material having a melting point of 137°C to 160°C, the resin composition having a mixing weight ratio of the components (A) and (B) satisfying (A) / (B) = 95/5 to 50/50, wherein the resin layer has a structure such that a soft structural portion (Y) of the component (A) intrudes into a space between crystalline structural portions (X) of the component (B). Therefore, the resin fuel tube is light-weight, excellent in impact resistance and heat resistance, free from fuel leakage, and usable in an atmosphere at 130°C or higher, for example, in an automotive engine room or the like.
摘要(中):
提供树脂燃料管,其包括至少一个树脂层,其中树脂层由树脂组合物制成,该树脂组合物包含:(A)通过使用茂金属催化剂聚合制备的聚丙烯; 和(B)熔点为137℃至160℃的聚丙烯材料,该树脂组合物具有满足(A)/(B)= 95/5的组分(A)和(B)的混合重量比 至50/50,其中树脂层具有使得组分(A)的软结构部分(Y)侵入到组分(B)的结晶结构部分(X)之间的空间的结构。 因此,树脂燃料管重量轻,耐冲击性和耐热性优异,无燃料泄漏,可用于例如汽车发动机室等的130℃以上的气氛。
