clear PVC order
Titus, "Cell cast" is used in the industry as you have to be able to tell the difference between that and "Continuous cast" we used continuous cast in the skylight factory whare I worked befor I got into the Navy, as for how strong, well it like anything else depends on the manufacturing and quality control. Extruded Acrylic is the most consistant when it comes to thickness but it optical quality isn't as good as the other types. this is the MAIN difference.. Cell cast is the highest optical quality, Continuous cast is next and then finaly Extruded.
now having said that Extruded ends up being softer than cast methods so it will scratch easyer and has a tendency to gum up tools more, also because of the softness it can adsorb solvents faster than cast which can result in incomplete or brittle seams. to corect this just use a solvent that sets up a little slower.
hope this helps
Steve
