Premium-quality, high-performance, engineering-grade, retro-reflective 5mil cast vinyl meets or exceeds Federal Specifications L-S 300C (Reflectivity 1) and ASTM-D-4956-99. The manufacturing process and raw materials used in making premium cast vinyl render it more durable.Īs a result, it will last a few years longer than standard vinyl. This manufacturing process creates a very thin - 2mil - vinyl that makes it more conformable than calendared vinyl.Īs a result, you can use it over substrates with rivets, corrugations, and complex curves.īecause the vinyl has not had any stress applied to it during the manufacturing process, it also does not have any shrinkage. Once cast, it is then processed through a series of ovens to harden. Premium-grade cast vinyl starts as a liquid mixture that is "cast" (or poured) onto a moving casting sheet. Our standard calendared vinyl has an outdoor durability of up to 5 years. Thanks to its high-yield bulk production method, calendared vinyl is less expensive than cast vinyl.Īnd because it is stiffer/thicker than cast vinyl, it is also easier to handle and install. These rollers flatten the vinyl down to a final thickness of 3mil.īecause it stretches into shape, the vinyl has some degree of memory and a slight tendency to shrink or pull back toward its original form when it gets hot. Standard "Intermediate"-grade calendared vinyl runs through a hot series of calendaring rollers in a semi-solid form. Close Vinyl Info Standard Calendared Vinyl:
