Looking for thin phenolic or fibreglass sheet

[snowyskiesau]

The title pretty much says it all.

I'm trying to track down a source of thin fibreglass or phenolic sheet/board.
The thickness I'm looking for is at least 4mm, if it's a bit over, I can machine it down.
I'm only after a small quantity, about 300mm square will do.

I've tried printed circuit board suppliers but their stock is 1.6mm, too thin.

$2 shop chopping boards Geoff

Oh hang on in my shelves I have what you may need will double check how thick.

PM sent

Edit Size is 400mm x 300mm x 6.5 will that do

Ray,
I've looked at the chopping boards but they are HDPE which is too soft for my purposes. It really needs to be a fibre reinforced plastic i.e. fibreglass or a resin impregnated cloth/paper like phenolic.
It needs to be an insulator and to be be oil and (possibly) solvent resistant..

I was thinking about getting some chop strand mat and resin and making my own, not sure if Bunnies sell this? There's no where else within walking distance of me and the buses are on strike today!

Check PM's also see edit above for size this is hard stuff would be oil resistant good enough to make a router plate out of.

Polycarbonate do? as you can buy it in 4mm thick.

Check with electrical wholesalers near you for suitable board, its used in switch boards and the like. Thicker canvas Bakelite sounds like it may do you as well as fibreglass board

I checked with the local electrical wholesaler the other week. They didn't stock anything of the thickness I was looking for.

wheelinround has offered me something the sounds like it will do the job.

The material I got from wheelinround isn't suitable for what I need to do.
I tried drilling a 1 mm hole near to the edge (as the final piece requires) and it isn't strong enough to hold a screw.
Not to worry, I have another project in mind for this stuff - I think it's acrylic.

I ended up making a board from a fibreglass kit from Bunnings (I knew it would come in handy for something).
About 8 layers of chop strand mat and about 100ml of resin. Thickness is 3.5mm +/- 0.1mm. The second picture gives an idea of the thickness and how uniform it is.

shame about that but I know you'll put it to good use Geoff like the project in mind
