What that means in practice

A PE100 rated at MRS 11.2 MPa rather than the usual 10.0, and that is the whole point of it — the extra strength is what allows very thick walls and large diameters. Do not confuse it with HE3490-LS-H, which is nearly the same code and an MRS 10.0 material.

If these numbers are not something you work with daily, our HDPE grades and pricing guide explains what they measure and how prime, off-spec, regrind and regranulate differ.

What to check before buying BorSafe HE3490-LS

• The classification is the specification: PE80, PE100 or PE100-RC, with the MRS figure attached. Two grades whose codes differ by one letter can be rated differently — BorSafe HE3490-LS is MRS 11.2 and HE3490-LS-H is MRS 10.0, and nothing on the sack will remind you.
• Colour is not cosmetic on pipe compound. Black is water and general pressure; orange and yellow mean gas across most of Europe. The wrong colour passes every mechanical test and fails inspection on site.
• For black grades, ask for the carbon black content and dispersion on the batch. That is what carries the UV life, and it is a batch property rather than something the grade name guarantees.
• If it is offered as off-spec or reprocessed, ask precisely what the deviation is. A compound that no longer meets its MRS rating is no longer the material the code names, whatever the paperwork says.
