TPX is Polymethyl Pentene
It certainly is NOT Methyl Methacrylate (PMA), and has very different properties to Methyl Methacrylate.
The only manufacturer I know is Mitsui.
I am sure you can find them by a google search, and from there you can find their agent in the UK
In Australia, it is 3 to 4 times the price of polycarbonate, and 6 to 8 times the price of Acrylic (PMA).
It is in fact a polyolefine and has many properties similar to Polypropylene and polyethylene.
It's features are:-
Exceptionally low SG of 0.81
Exceptionally high heat deflection temp for a polyolefin.
Exceptionally good chemical resistance typical of a POLYOLEFIN
It is the only thermoplastic that is transparent in it's crystaline state due to the unique coincidence that the refractive index of the crystaline and amorphous phases are identical. This of course gives a unique opertunity to obtain the properties typical of a crystaline material combined with transparency.
No I have connection with Mitsui nor their Australian agent, in fact their Australian agent retrenched me some years ago, as one of their Marketing Degree guys decided that technical support was not necessary to sell Engineering Plastics. They are now out of business. I am not (.I
