ACRYLITE® Resist Technical Information

TECHNICAL INFORMATION ACRYLITE Resist Physical Properties for Extruded Sheet Physical Properties Benefits Continuously manufactured ACRYLITE Resist sheet is a versatile thermoplastic material developed for the retail display and glazing markets as well as other markets requiring strength appearance and weatherability. Impact Strength This high optical quality sheet provides the beautiful look of acrylic with much greater impact strength for durability during manufacturing shipping and in-store use. Rigid tough and lightweight ACRYLITE Resist is easily fabricated and machined including cutting routing forming and cementing. Applications Commercial Lighting POP Displays Store Fixtures Glazing Sneeze Guards Social Distancing Applications Exhibit and Tradeshows Skylights and Daylighting General Fabrication Warranty ACRYLITE Resist acrylic sheet comes with a 30-year warranty that allows for little loss of light transmission and yellowness. Product Specifications Color Color Number Colorless 0RA45 GT Colorless 0RA65 GT Size Thickness This superior performance sheet has many times the impact strength of glass and standard acrylic sheet. Testing per ASTM D 3029. Lightweight ACRYLITE Resist sheet weighs half as much as glass. Heat resistance It keeps its rigid shape up to 160F. When subjected to temperatures below 32F and higher than 100F this sheet begins to appear hazy. Once the sheet equalizes between 60-80F it returns to its original high light transmitting clarity. Dimensional Stability ACRYLITE Resist will expand or contract when exposed to temperature or humidity change. The materials post-forming stability is excellent however shrinkage will occur when an un-clamped sheet is subjected to forming temperatures. Strength Stresses The tensile strength is 8900 psi at room temperature ASTM D 638. For applications subject to continuous loadings the design should allow for a load that will not exceed 600 psi at 73F 23C. Continuous loads well below 8900 psi will

lead to stress crazing and eventual failure.

ACRYLITE Resist Physical Properties for Extruded Sheet Light Transmission Cutting Machining Colorless ACRYLITE Resist light transmittance is greater than 91 18 thickness. It retains high light transmitting properties for many years. The sheet is cut and shaped using all of the same machining operations used with standard extruded acrylic sheets. i.e. cutting routing drilling etc.. Weather Resistance Cementing It is manufactured from weatherable acrylic polymer. It can be used outdoors for many years with little loss of impact strength or its acrylic-like appearance. Common solvent cements or polymerizable cements work well when joining this material to itself or other acrylic sheet products. Care must be taken to provide a sheet edge that is machined properly and contains low stress. A generous amount of cement should be applied along the entire length of pieces being joined taking care to ensure the cement fills the entire area between the pieces. Flammability ACRYLITE Resist acrylic is a combustible thermoplastic. Precautions should be taken to protect this material from flames and high heat sources. This sheet usually burns rapidly to completion if not extinguished. The products of combustion if sufficient air is present are carbon dioxide and water. However in many fires sufficient air will not be available and toxic carbon monoxide will be formed as it will when other common combustible materials are burned. We urge good judgement in the use of this versatile material and recommend that building codes be followed carefully to assure it is used properly. This material is a UL recognized component UL flammability rating 94HB. Please refer to the ACRYLITE Resist Fabrication Manual fo

r detailed information. Annealing This sheet may be annealed at 180F with the heating and cooling times dependent on sheet thickness. An approximate guideline is annealing time in hours is equal to the sheet thickness in millimeters to a minimum of two hours the cool down period should be a minimum of two hours ending when sheet temperature falls below 140F. Fabrication Chemical Resistance Formability The forming temperature range is 270F - 350F. It softens with temperature increases above 220F thus passing through the thermo-elastic to the thermoplastic state. This change is gradual rather than sharply defined. Because this change is gradual certain procedures should be considered during thermoforming. If the sheet is to be hung in an oven a continuous clamp rather than several individual clamps must be used preventing permanent deformation of the sheet between clamps. If the sheet is heated by infrared heaters supported in a horizontal frame control of the heaters positioned over the center of the sheet will prevent over heating the center of the sheet which could cause an excessive amount of sagging. ACRYLITE Resist acrylic is resistant to many chemicals some of which include Solutions of inorganic alkalis Diluted acids Aliphatic hydrocarbons It is attacked in varying degrees by but not limited to Aromatic solvents i.e. benzene and toluene Alcohols Chlorinated hydrocarbons i.e. methylene chloride Lacquer thinners esters ketones and ethers Its resistant to most chemicals in normal use with resistance to fatty and oily products. There is no measurable permeation or adverse effect on the material in contact with oils and aliphatic hydrocarbon-based products. ACRYLITE Resist 3059D Technical Information 1124 page 26 ACRYLITE Resist Physical Properties for Extruded Sheet Chemical Stability The data was gathered at 68F 20C and 50 relative humidity. Results vary depending on the temperature and moisture content of the material. In practice resistance is depend

ent on internal and external stresses as well as the method of fabrication. We recommend appropriate testing. This sheet meets FDA requirements for use in many food contact applications.
