Might be, that any thermoplast is a good choice. An idea which one?
As requested, I'll provide some further Information. However, please do NOT ask, why I wanna do that (obviously without further information my acting seems counterintuitive)...
I want to realize a thin film of this polymer for example by spin coating. Afterwards, the thin polymer layer will be peeled of the substrate. The tensile strength is needed in order to grab the thin film by tweezers without ripping it. Then, the thin film will be clustered by random folding or likewise. Here flexibility is essential, though I guess the thinner the film, the less important the flexibility might be. Finally the clustered "ball" will be treated with heat, where the intention is to melt the polymer. The continuous use will be at room temperature.
Can you clarify the continuous use temperature or other environmental conditions for the application and define more clearly the needed tensile and flex modulus you need?
Hi Kay,
In fact I'm doing some experimental investigations on XLPE samples, and I can see that this material has quite similar characteristics to that you indicated, it consists of a high optical transparency, a melting temperature of 130°C, a good flexibility (elongation at break is about 600%) and tensile strength is about 20 MPa.
Hope it will help
Ok. A few more clues but honestly why the secrecy??? Of course, you probably want to protect some kind of patent possibility (IP). So you can't risk an inventive contribution from someone else ... eh? So here is all you get for free (after that you can pay my usual consulting fee. The following polymers can be spun coated from a solvent and would be optically clear from 500 - 850 nm (i.e. visible light region), melt below 250 C, and have decent tensile (I think flex won't matter if the film is thin enough) - General Purpose polystyrene, polycarbonate, m-LLDPE, etc. But, depending on your definition of "optically clear", you could start to run into trouble with these materials in the 850 nm to 1500 nm (Near Infrared, NIR). There will be some absorbance bands for some of these materials in the NIR range, albeit weak bands. Above 1500 nm these materials probably won't work for you, again assuming you really need optically clear. One polymer melting below 250 C with good optically clarity across your entire wavelength range is the fluoropolymers ETFE (e.g. Daikin ETFE 521, attached product brochure). ETFE extrusion films are available from Saint-Gobain Performance Plastics as you won't spin coat this material (but why would you really want to go to the trouble of spin coating. Or you could go with PVDF (Arkema) dissolved in NMP or some other similar solvent for spin coating and that meets all of your currently known criteria. Any more information and then you can hire me as a consultant (under Non-disclosure Agreement) and pay the fee.
