You used to be able to go to the Gordon's Composite website and get all kinds of technical info, but no more. Gordon's was acquired by a large multination corporation, PolyOne in 2016. Since then they have been systematically eliminating all available information. If you go looking you will find yourself going in circles.
It's speculation on my part, but historically this process is a harbinger of doom. Gordon's might have a large share of a niche composites market, but it's a small market to a large corporation. I am waiting for the day they disappear completely. Corporate profit structure is not nostalgic or forgiving.
I believe BearPaw only produces clear and black. If we are lucky they might start to make colors, if they see an opportunity.
