Additives for Polymers
MATERIALS Eckart introduces metallic micropellets for plastics in America Eckart America has introduced the silver MasterSafe® Micropellets range of new and improved metallic effect pigment pellets for the plastics industry. The new line complements the company’s established Eckart MasterSafe brand. The new pellets contain 75% metallic pigment, with the remainder a universally compatible polyolefin. They are mainly recommended for polyolefins; however, they can be applied in other plastics that can tolerate small amounts of polyolefins, the company says. MasterSafe Micropellets offer exceptional brilliance with no marking, according to Eckart. They are dust-free and easy to disperse. The pellets are free of solvents and have very low odour, and are suitable for use in food packaging. Five different D50 micron sizes are offered for varying degrees of fineness: 29 micron (finemedium), 34 micron (middle), and 50 micron (middle-coarse), all used for blending with colour pigments; and 68 micron (middle-coarse) and 85 micron (coarse) for producing a fine sparkle effect. A brochure highlighting the features and benefits of the MasterSafe Micropellets is available from the company. Eckart America, founded in 1997, is part of the Eckart GmbH & Co group which is being acquired by Altana Chemie AG [ADPO, September 2005].

as the Surlyn® packaging resins from DuPont. According to the company, these masterbatches can also be used with films made from ethylene vinyl acetate, ethylene-methyl acrylate and nylons, among other materials. The new masterbatch series currently contains three members – Ampacet 101350 slip, Ampacet 101326 antiblock, and Ampacet 101053 slip and antiblock combination. All of these grades are FDA compliant and can be used in food packaging films, especially for meat and cheese products, the company says. Ampacet claims to be the largest volume producer of masterbatches in the world with a global capacity of more than 400 000 tonnes/y of custom colour, special effect, black, white and speciality additive masterbatches for extrusion, moulding and other applications.

Clariant offers halogen-free flame-retardant masterbatches in North America Clariant Masterbatches’ new CESA®-flam flame-retardant masterbatches offer an environmentally friendly alternative to conventional halogenated flame retardants. Developed specifically for use with engineering resins including polyamides, polyesters and thermoplastic urethanes (TPUs), these additive masterbatches are available in North America through Clariant’s Winchester, VA, facility. Based on proprietary phosphorus compounds instead of halogens, the new Clariant masterbatches achieve their flame-retardant property through intumescence, the company says. When exposed to fire, the flame-retarded thermoplastic material foams and crosslinks, forming a stable char at the surface. This ceramic-like protective layer provides a heat-insulating effect, reduces oxygen access, prevents dripping of
