EPU TECHNOLOGY - WHAT IS IT?

HOW DOES THE HELMET WORK?

Firstly, by wearing a helmet any impact made to the head is absorbed by the helmet, NOT the head.

1. IMPACT DISTRIBUTION - The stronger the outer strength is, the better the impact is distributed. Prowell's one-piece mono-coque helmet body is extremely strong

2. IMPACT ABSORPTION - The denser the inner cell structure is, the better the impact is absorbed. EPU is made up of more compound cells and an increased amount of embedded air to resist and absorb any impact. For example; upon impact, a compound cell is broken to absorb the impact energy and with the increased embedded air, this helps to resist any impacts.

SO WHAT IS EPU?

EPU or Expanded Polyurethane is a dense, fine and very uniform cell structure. It forms like a bread dough, in one piece, protecting anything inside it. It's a natural, hard shell which helps to distribute any impact over a wider area. Another example of where EPU is used is on some car bumpers. EPU has a very solid feel to it and looks more aesthetically pleasing than other types of cycle helmet as it is a one piece structure as opposed to a partial coverage shell over foam.

THE BOTTOM LINE

There are other types of cycle helmet materials on the market, however EPU remains an innovative crushable foam that performs well in hard impacts, is light, durable in use, reliable to manufacture, easy to ventilate and looks good. Polyurethane is highly flexible therefore more resistant to damage as well as exhibiting less imperfections than other commonly used foams.
