Ampacet additives work with ionomers
Ampacet has developed a series of anti-block and slip masterbatch additives for use with films made with ionomers.
Three products debuted so far are Food and Drug Administration compliant, making them suitable for packaging meat, cheese and other such products. In addition to compatibility with ionomers like DuPont Co.'s Surlyn, the masterbatches are useful for films containing ethylene vinyl acetate, nylons and ethylene methyl acrylate, among other polymers.

New Zotefoams foam is high-performance
Zotefoams plc has introduced a fluoropolymer foam for high performance in building insulation and sealing products.
Zotek F-30 LS is based on Kynar-brand polyvinylidene fluoride supplied by Arkema Inc. It combines high thermal-insulation values with flame retardance and low smoke values, said Croydon, England-based Zotefoams.
Ultraviolet and chemical resistance help ensure longevity, and the closed-cell structure resists moisture, according to the company. The foam is supplied in sheet form.

Cesa-flam features char-layer insulation
Clariant Masterbatches claims its new nonhalogen, flame-retardant masterbatches are alternatives to conventional materials containing chlorine or bromine.
The Cesa-flam masterbatches are designed specially for engineering plastics such as polyamides, polyesters and thermoplastic polyurethanes. The Clariant additives masterbatch business based in Winchester, Va., said the new products are based on phosphorus compounds that promote polymer foaming, cross-linking and a surface char layer when exposed to fire. The char insulates the polymer from heat, reduces oxygen permeation, cuts down on dripping of the polymer and lowers smoke density and toxic emissions.
The company said its Cesa-flam line is high-temperature-stable, processes easily and takes color readily. Using flame-retardant additives in masterbatch form makes it easier to change dosages as each part requires, according to Clariant Masterbatches.

Firms form alliance for product quality
Ashland Composite Polymers formed an alliance with Signature Control Systems Inc. of Denver to help thermoset composite molders improve product quality and reduce scrap.
Ashland Composite, a business of Ashland Inc. of Dublin, Ohio, brings its spiral-flow mold technology to the alliance, combining it with Signature's SmartLab technology. SmartLab allows technicians to characterize a molding compound quickly, by analyzing electrical impedance curves, mold temperature and pressure, and material flow.
The partners' agreement gives Ashland Composite Polymers exclusive global rights to market the combined technology. They said it is the first time thermoset molders can apply dielectric technology with material displacement and proprietary software to improve molding performance.

Latest Arkema resin helps color control
Arkema Inc. claims better color control in thermoset resins when its new methyl ethyl ketone peroxide initiator is used.
The Philadelphia firm says Luperox disappearing-red MEK peroxide imparts a red color when mixed into the resin, assuring the processor that initiator is part of the mixture. During resin cure the red color disappears, unlike when permanent dyes are used to denote initiator content. Processors have more color freedom with the system, Arkema said.
Arkema so far has developed three disappearing-red versions of its Luperox initiators and claims more are on the way. The firm plans to feature the technology at the American Composite Manufacturers Association Meeting scheduled for Sept. 28-30 in Columbus, Ohio.
