" From: gqrxzy8974@xxxxxxxx " " [] " " So far I've found out that while polycarbonate won't likely break upon " impact it is eventually destroyed by UV (3+ or so years, yellowing " then cracking) and doesn't like certain chemicals (PVC for one, again " cracking). Glass could break... :-( acrylic isn't as strong or impact resistant as polycarbonate, but it's uv-hardy and one of the hardest and most scratch resistant plastics. i vaguely recall hearing of the existence of uv blocking coatings for these plastics. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
