Is UL Certification for Polyimide Tapes necessary?

In an ear­li­er post, we asked this ques­tion, but it’s come back again and again, so we want to address again, in more detail, and with an aim for dis­cus­sion.

We are often asked if our prod­ucts are UL Cer­ti­fied. Cus­tomers often as us because they in turn need to pro­vide UL cer­ti­fi­ca­tion on their prod­ucts. We under­stand this, but that’s almost beside the point.

The rea­son is because UL cer­ti­fi­ca­tion is giv­en on a prod­uct-by-prod­uct basis and each UL cer­ti­fi­ca­tion test costs about $1000. If we get UL cer­ti­fi­ca­tion on PIT1S (1mil sil­i­cone adhe­sive poly­imide tape) then this does not mean it extends to PIT1A (same poly­imide back­ing but acrylic adhe­sive instead of sil­i­cone) or to PIT2S (same poly­imide back­ing, same sil­i­cone adhe­sive, 2mil thick­ness instead of 1mil).

So, yes, we can make extrap­o­la­tions based on the results of the data, but we can­not “extrap­o­late” UL-cer­ti­fi­ca­tion. So what’s the point? Fur­ther­more, cus­tomers often require UL cer­ti­fi­ca­tion on the final prod­ucts they make that [i]use[/i] the poly­imide tape, which means they still have to go through UL cer­ti­fi­ca­tion of their own — [i]whether or not CAPLINQ has UL-certification[/i].

So the short answer to the ques­tion is YES, we have UL-cer­ti­fi­ca­tion on [i]some[/i] prod­ucts, NO, we do not have UL-Cer­ti­fi­ca­tion on [i]all[/i] prod­ucts, and YES, we can

get UL-cer­ti­fi­ca­tion on the poly­imide tapes you require — this is only con­di­tion­al on the num­ber of rolls in ques­tions and who will pay for the UL-cer­ti­fi­ca­tion.
