Abstract:
A compressible tube having improved resistance to stress-cracking in the tube due to chemical attack, having a wall made of a thermoplastic polymer blend comprising:(a) a first ethylene/C.sub.4 to C.sub.5 olefin copolymer having a density of 0.910 gm/cm.sup.3 or less and(b) a second ethylene/C.sub.6 to C.sub.10 olefin copolymer having a density of 0.915 to 0.930 gm/cm.sup.3,wherein the first copolymer (a) is present in the polymer blend in an amount of less than or equal to 50 wt. %, with respect to total weight of the polymer blend, andthe blend has a melt-flow index of about 10 gm/10 min.wherein the compressible tube is obtained by injection-molding the polymer blend.
