Clear extruded flame retardant durable film

Clear extruded flame retardant durable film

Clear extruded flame retardant durable film

(OP)
My company does not have an extruder so I've been looking for a company that can extrude small quantities of a film (~5000 lb/year 6 mil 60" wide)for us. It's got to be clear and mar resistant with a fairly high COF (>0.25 when wet), include flame retardants (must pass a 12 sec vertical burn) and not release a significant amount of chlorine or flourine when burned. In addition it must be able to adhere to a PVC based ink and not cause delamination of that ink from a PC/PVAc substrate when pressed at ~275 F ~150 psi.

The basic goal is to have a clear film that can display a graphic and be used as a flooring material. I've had some moderate success by making my own coating but I simply cannot acheive the durability of an extruded film. I found one company who's product worked but lacks flame retardants http://www.argotecinc.com/techsheets/Argotec%2029213.pdf . They are only willing to add flame retardants if we purchase 15-20,000 lb/year which we simply don't have the marketshare for yet.

Anyone know of a film or a company that could make such a film?

Look at DuPont Tedlar.

Thanks for the response,

We currently do use Tedlar in some of our products. Unfortunately, Tedlar is extremely slick (COF <.1). Originally I tried adding acoating on top of tedlar but the adhesion is so pour it had to be almost 100% urethane which would yellow and mar easily. Also the the burned material I think might not pass our toxicity requirements.

Thanks Mcgyvr (love the show :D)

I've actually tried the lexan material but it's also just too slick for my application.

Mitsubishi looks good. I actually contacted them almost a month ago about hostaphan but the rep I talked to was travelling and said he'd get back to me after he talked to his technical guys. Maybe I need to give him another call eh?

What are you using to print the graphics on with?
We have had no problem silkscreening to lexan polycarbonate films in the past. Its all in the ink you use.

We're printing with a mimaki JV3 digital printer. The problem isn't that the graphic won't adhere to lexan, it's that the lexan is so hard that it has a low coefficient of friction even when we emboss a texture onto it.
