Polyethylene is a thermoplastic polymer consisting of long chains of ethylene or ethane. It is a wax-like thermoplastic with a density less than the density of water. The only two additives added to polyethylene are Carbon Black, within the range limit of 2-3%, to add reinforcement and increase polyethylene’s weathering properties and trace amounts of antioxidants. The Pipes & Fittings are offered in PE 63, PE 80 and PE 100 grades, compliance to IS-4984.
