NanoSeal targeted for wire, cable uses
Nylon Corp. of America is touting its barrier nanocomposite NanoSeal for wire and cable applications.
Originally targeted for small fuel tanks to meet stringent California emission standards, NanoSeal provides a high barrier to moisture, oxygen and hydrocarbons, according to the Manchester, N.H., firm. The material is made by polymerizing nylon with clay in a reactor to give high dispersion of clay platelets. NanoSeal with 3-8 percent clay loading provides barrier properties for wire and cable, fuel tanks, film and tubing.
Nycoa also said its Nycolastic thermoplastic elastomer based on nylon copolymer also is suited to wire and cable, imparting chemical and temperature resistance when used to protect PVC insulation.

Ampacet introduces PET masterbatches
Ampacet Corp. has introduced PET masterbatches that can be used without predrying and that have the potential to reduce problems such as feed-throat clogging and screw slippage.
Formula X masterbatches are suited to stretch blow molding, injection molding and thermoforming. The Tarrytown, N.Y., firm said they provide good dispersion of colors, additives and even special-effect pigments such as pearlescents and frost effects that normally are hard to get in PET.
Unlike liquid colors or wax-based colors, Formula X materials are compatible with bottle-grade PET and their viscosity is similar to PET, leaving bottle properties unchanged.
The masterbatches can be fed directly into the throat of a machine and they don't require several hours of drying typical for PET resins.

ColourTone can make rigid coloring flexible
ColourTone Masterbatch Ltd. has helped develop a PVC masterbatch that makes it easier to add color to rigid vinyls.
Conventional rigid PVC masterbatches have had problems with compatibility and homogeneity that affect physical properties, according to the Bedwas, Wales, company. ColourTone's new masterbatch is easily dispersed at dosages of 1-2 percent in filled or unfilled rigid vinyls.
The firm claims the product can help reduce inventories by making colorization more flexible. The masterbatch also works with flexible vinyls.

Keco touts toughness of composite coating
Keco Coatings has codeveloped a rotational mold composite coating with the toughness of tungsten carbide and the release properties of a fluoropolymer.
Keco of Indianapolis said the Keco 600 Tex/Release TM Coating provides a secondary textured finish to rotomolded products. Applicable to new and existing molds, the coating is available in a range of finishes and release properties. It can be used to treat most steels, and aluminum alloys and castings, according to Keco. Rivers Metal Products Inc. of Lincoln, Neb., helped develop the new coating, which the partners introduced at the Association of Rotational Molders fall meeting in Washington.

Aardvark formulates alloys for rotomolders
Aardvark Polymers has debuted thermoplastic alloys formulated for rotational molding.
The Lambertville, N.J., firm said the base materials typically are engineering grades of acetals, nylons and polyesters compounded with other polymers. The range of properties of the Aardalloy product line include high impact and other strength ratios, reduced friction and wear, high continuous service temperature, better ductility, chemical resistance and creep resistance, the firm said.
Aardvark claims the new materials will allow rotomolders to partake in markets formerly out of bounds because of limitations of available materials. The Aardalloys are customized per target application.

Reichhold additives aid smooth profiles
Reichhold Inc. has added two new low-profile additives designed for pultrusion and compression molding.
Polylite 31702-40 is a 40 percent solids additive for pultrusion that allows operators to make glossy and smooth profiles when cosmetic properties are important.
Window lineals, ladder rails and tool handles are envisioned applications, according to the Research Triangle Park, N.C., company.
Polylite 31701-35 is a 35 percent solids polystyrene for sheet and bulk molding compounds where reduced shrinkage is desired during compression molding. Residential door skins are one targeted use.
