Rotomoulding

Rotomoulding coatings by EHRI

We line the inside of steel parts with a seamless fluoropolymer layer, so they resist corrosion and aggressive chemicals. We do this by rotomoulding, also called rotolining. We have been doing it since 1989.

PS 401

ETFE PS 401

We used to work, like everyone else, with standard ETFE, PFA, PTFE and PEEK. Ordinary ETFE costs less than PFA but cannot handle such high temperatures, so at higher temperatures PFA, PTFE or PEEK was often needed. In our own lab we developed PS 401: an ETFE that handles higher temperatures, up to 180 °C.

What PS 401 does

PS 401 is an ETFE coating that can be used up to 180 °C and has good chlorine resistance. So it can be used in many places where PFA, PTFE or PEEK used to be needed.

What it saves

PS 401 costs considerably less than PFA or PEEK. So you pay less for the same protection.

History

Since 1989

In 1989 we were the first in Europe to apply internal ETFE and PFA linings by rotomoulding.

Since then we have kept developing the machines, the control system and the coatings, mostly in-house.

Engineering

Our own machines and control system

The machines on the market did not do what we wanted. So we designed and built our rotomoulding machines ourselves.

Every part recorded

The machines run on software we wrote ourselves. It controls every step of the process and compares the measured values with the set values for each product.

That way every coating is equally uniform, and we can look back at how each part was made.

Price

A price, quickly

We also built our own order system and calculator. That lets us give a clear price quickly, with no surprises afterwards.
