What that means in practice

The RC in PE100-RC means resistance to crack, and it is bought for how the pipe is installed rather than for what it is rated to hold — sand-free trenching, ploughing, relining. At MRS 10.0 it is a lower-rated material than HE3490-LS despite the near-identical name.

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-H

• 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.
