Slon Bend 90°

INTRODUCTION

PVC pressure pipes are manufactured from unplasticized polyvinyl chloride polymer (a thermoplastic material) using the extrusion process. PVC (also known as uPVC and PVC-U) pipes were introduced to Sri Lanka in the late 1950s by S-lon and are now widely accepted for use in water supply, irrigation and sewerage rising mains.

MATERIALS

S-lon uPVC is stabilized with compounds conforming to the International safety levels (Non Lead) for vinyl chloride monomer (VCM) and the WRAS requirements for use with potable water.

COLOUR

uPVC products are recognized by their light grey colour.

CHEMICAL RESISTANCE

The chemical resistance properties of uPVC is excellent: it is resistant to most solutions of acids, alkalis and salts and to solvents that can be mixed with water. uPVC is not resistant to aromatic and chlorinated hydrocarbons.
