UHMW, UK Supplier for this material

It is a few years since I have worked with polymers so things might have changed a bit.

UHMWPE can be entertaining to process hence my query.

If you want some guides for tools Al, I am assuming you want sheet material and presumably in relatively small quantities.

Am not sure that UHMWPE would be the best material for your application.

Try discussing your applications with the technical support guys at Barkston on 0113 249 2200 they may be able to guide you to the best material for your application Al.

Hope that helps

Yes, I just need some modest strips of it.

Al.

Ahh, always a snag.

As a supplier (not a user who could supply offcuts) I found Kiowa to be both helpful over the phone, and the best price. I was a mail order customer.

Best price covered several aspects:

They had the tape cut to the width I wanted, so I wasn't buying waste.

The price per standard roll was cheaper than anywhere else I found.

As I wasn't in a desperate hurry, they offered to hold my order for a day or two, so it went in their regular order to their supplier, thus I avoided a 'small shipment' charge.

My intentions were use for challenge wing material, 1 metre square sheets, say 5-10mm thickness. The material seems popular in the states for applications that can take a beating. See piccy below, as the boatsides on this XJ are said material.

Searched UHMP on the bay and came up with these Hawse's though. Not what i was looking for but, interesting.

Hi Al, for tool guides have you considered the Delrin grades of POM? The technical help guys at Barkston used to be very helpful when we were after small amounts of material for research purposes, so they are worth a phone call.

W/hog that hawser guide looks interesting but I am dubious about some of their claims, especially about lubrication. The guide could also be damaged by rocks etc but any burr on that hawser would not be as damaging to a syntheticltine as a burr on an aluminium hawser.

Have you considered a material called Comtex? It is a one piece composite made out of drawn PE fibre. I know that Safety Devices were considering using it as a tank guard as we made a prototype for them. It has low friction and reasonably high abrasion resistance. It is lightweight, pretty tough reasonably bullet proof (i.e.stops a .44 magnum but not a 5.6mm high velocity round) and is probably stronger then UHMWPE as it is made from drawn PE whereas I suspect that the sheet material of UHMWPE is not drawn. Ford were also interested in the material and funded some of the research.

Not sure what happen with the commercialisation these days but the University of Leeds were certainly trying to commercialise it. Believe the group responsible might have moved to Bradford now.

Hope that helps

Regards

Brendan

This takes me back to my design engineer days in the reciprocating and rotary seal industry.

Try Ensinger. UK-based. They may still have a place in Portsmouth, but are also based in Llantrissant.

There's loads of engineering plastics dealers around, but most buy from Ensinger, so they would be the best to call or recommend a local stockist.
