Method of forming stabilized porous pipe |
摘要 |
Porous pipe formed by extruding a mixture of particles of vulcanized rubber dispersed in a binder resin such as linear low density polyethylene preferably having a Melt Index below 1.0 and a broad distribution of molecular weights, through a pipe die to form porous pipe and then cooling the pipe in a cooling trough. The pipe is stabilized to reduce degradation by ultraviolet light by dispersing in the binder resin an effective amount of an ultraviolet stabilizer such as 0.1 to 10% by weight of carbon black.
