Tuf-Glas Continuously Processed Impact Acrylic Roll Stock offers the clarity and stiffness associated with acrylics combined with toughness at least seven times tougher than standard acrylic. Conventional solvent cements will join Tuf-Glas. Standard sign paints such as Grip-Flex and Lacryl can be used to decorate the surfaces. Cutting can be done with power sawing equipment with blades from 4 to 8 teeth per inch, bands saws from 10 to 14 teeth. All edges are trimmed and the sheet is masked with a poly coating so it gets to you in good condition.

 Why Choose Tuf-Glas Impact Acrylic Roll Stock?

   Tuf-Glas Impact Acrylic Roll Stock can be sawed, drilled, and routed with standard equipment and procedures recommended for conventional acrylic sheet. Painting, silk-screening, vinyl application and other decorative techniques are easily accomplished; and Tuf-Glas can be joined to itself or other materials by adhesive or solvent bonding.

  • Cutting. Tuf-Glas can be cut with standard power sawing equipment including table saws, band saws and circular saws if proper clamping devices are used.Standard hollow-ground, high-speed cross-cut steel blades are adequate, but carbide-tipped blades are suggested for longer life. Saw blades should have a 0-5 degree positive rake angle. There should be from four to eight teeth per inch depending on sheet thickness. All teeth should be of uniform height. Saws should run at speeds of 8,000 to 12,000 linear feet per minute. Band saw blades should have 10-14 teeth per inch; blade speeds should be between 4,000 and 5,000 feet per minute

 • Drilling. Tuf-Glas may be drilled with modified, standard high-speed, steel twist drills. The drills should have slow spirals and wide polished flutes. The included tip angle should be ground to 60 degrees and the cutting edge dubbed off to a zero degree rake angle. The back lip clearance angles should be ground to 12-15 degrees.

 • Cementing. Conventional solvent cements and polymerizable cements will readily join Tuf-Glas. Polymerizable cements give higher joint strengths than solvents.

 • Painting. Tuf-Glas can be easily painted and silkscreened with standard sign paints for acrylic sheet; impact additives may be used if desired. Grip-Flex® and Lacryl® spray and screen paints have been thoroughly evaluated and field-tested. Paint can be removed with Trialene soap or a 50/50 mixture of VM&P Naptha in combination with any of the following: Grip-Flex T-1005; Lacryl 205-T; or solvent 100. More aggressive solvents or mixtures can cause crazing, particularly in thermoformed faces with residual stresses; remove solvent from plastic sheet as quickly as possible to avoid solvent attack. Follow the manufacturer's guidelines for proper painting and paint removal procedures. Tuf-Glas Very High Average

 • Thermoforming. Tuf-Glas forms very easily with better detail at lower temperatures than cast acrylic sheet, on virtually all thermoforming equipment from high-volume, multi-station rotary machines to single station and shuttle presses. Thorough heat-soaking is recommended for good part detail with minimum residual stresses. Forming temperatures range from 275-350°F, with optimum sheet temperature at a uniform 325°F. Part removal temperature should be no greater than 190°F. Tuf-Glas forming cycle times can be as much as 25% faster than cast acrylic.
