  • Colorful durable surface graphics
    Sublimation decoration process deposits colorful graphics beneath the surface of light-colored plastics and coatings. Polaris Industries Inc., Medina, Minn., has been using dye sublimation on its camo-decorated ATVs for the past two model years. Prior to dye sublimation Polaris used a "dip" process
  • Plastics Processing Applications: Textile Fiber Production
    and thickness. The key concern of the manufacturer is that the color of the fiber is uniform and consistent, with no visible variations in color. To ensure consistent color in the final product, resin/dye blending is increasingly performed gravimetrically by weight rather than by the less accurate
  • Getting Big Protection with Small Technologies
    Operational Excellence & Lean Six Sigma Primarily phosphors and specialized dye molecules, these markers can be added to inks and coatings and, when analyzed under certain lighting, provide a unique fingerprint for a product. They can be administered by inkjet and other commonly used printing
  • Mastering color
    , eliminating halogen and creating an acid, which may degrade materials by overpowering compounding in stabilizers. Colorant selection: Dyes maintain base resin properties better than pigments and special effect colorants. However, each has pros and cons. For example, using pigment instead of a dye
  • Coloring outside the lines
    resins, rather than from stock color chips or printed swatches. Likewise, color concentrate manufacturers may use different pigments and dye systems to match the same color, so designers must exercise caution when switching suppliers. Substitute concentrates may produce a match under one type
  • Large Steel Coil Processor Marks For Safety, Quality Checks With High Legibility a Key To Success
    . It is recommended for both porous and non-porous substrates and includes metals and galvanized steel, plastics, packaging, wood, building materials with dye or pigmented ink formulations. The device has dynamic message storage memory of up to 400 characters per line of text and as many as 200 messages
  • Therapeutic Dose: The Perfect Storm
    (Glenn van Buskirk) was reformulating a chewable Ritalin tablet. Before he proceeded to stability trials, he asked if the new ingredients might interfere with the current assay. In fact, the red dye (they were cherry-flavored, if I recall) interfered with the colorimetric assay, which developed
  • Efficient use of fluorescent whitening agents
    a traditional concept of tetra-sulphonic FWA in the wet end and film press. The following example is taken from a grade with ISO Brightness of 113 (CIE Whiteness 160). During the trial, a clear trend of decreasing FWA amount required in the wet end was observed when the shading dye was changed to IRGALITE
