Abstract

Microporous, water permeable pipes are prepd from a mix based on reground vulcanized rubber of an average 0.5-2.0 mm particle size to which at least 7% of powdered thermoplastic is added, pref. high pressure low-density polyethylene, as well as 0.1 wt% of a mixt of penta:chloro-thio-phenol and an organic-metal-complex cpd, 0-0.05 wt% rubber and/or plastic additives, as heat light and UV stabilizers and/or fungicides, and bactericides. The mixt is fed into an extruder at 140-200 deg.C, pref. 160-180 deg.C and extruded via a mesh with less than 1 mm apertures. Material leaving the high pressure extrusion head is cooled intensively, resulting in microfissures during contraction due to the dissimilarity in the coefficients of linear expansion of the two materials.
