I'm confused.................a bit more than usual.
I have always believed that the UV protection for Premium Clear Acrylic is 66%. That's what TruVue states on their site. I can't find anything for Evonics FF3 anywhere. I have seen a couple of things lately where folk are claiming 90% plus UV protection for their acrylic without anything to back up their claims.
In the WireCutter article mentioned in another thread - https://www.nytimes.com/wirecutter/reviews/best-online-framing-services/ The Best Online Framing Services they state that their UV Protection for Framebridge regular acrylic is 92% although I can't find anything about this on their site.
In addition I have seen some vendors on Etsy state their regular acrylic is 92% protection also.
I can't find anything,anywhere that validates this.
What I have found is this:
With impeccable clarity, excellent weatherability, and high light transmission, this plastic has no additives to block the transmission of UV light. While UV filtering acrylic blocks up to 98% of UV rays, UV transmitting acrylic allows up to 92% UV ray transmission.
I have also seen :
Colorless ACRYLITE acrylic sheet has a light transmittance of 92%,
None of the literature I have read mentions ANYTHING AT ALL about UV Protection of Premium Clear/FF3 acrylic leading me to believe that folk are reading the 92% light transmission number as UV Protection and falsely misleading folk into believing that Clear Acrylic has a high degree of UV protection.
Can anyone shed any more light (pun intended) on this?
If I can find some further clarification on this and that folk are misleading dolk I will update my page on Misleading Acrylic terms at https://www.thepaperframer.com/misleading.php Misleading Acrylic Terms
