starting up industry & technology news conair & Rapid Parent Buys thermal care IPEG, Inc., Cranberry Township, Pa., has acquired Thermal Care Inc., a major manufacturer of mold-temperature controllers, chillers, cooling towers, and pump tanks. IPEG is the parent company of The Conair Group and Rapid Granulator. It also recently bought Republic Machine, a maker of shredders (see last month's Starting Up). While Conair has its own line of Thermolator water products, it rarely competed directly with Thermal Care. Based in Niles, Ill. Thermal Care will continue to operate there as a wholly owned subsidiary of IPEG. Tom Benson, a 25-year employee and former v.p. of sales and marketing for Thermal Care, was named president of the company. new economical Pathway to Bio-Pet Micromidas, Inc. of W. Sacramento, Calif., has developed a catalytic route to making paraxylene from cellulosic biomass and ethylene. Recent trials reportedly indicate that the process, which involves no fermentation, is cost-competitive with petroleum-derived paraxylene, a building block that constitutes 70% of the PET resin molecule. Up to now, only the 30% portion based on monoethylene glycol (MEG) could be renewably based on ethylene derived from sugarcane ethanol. The Micromidas development is one of several projects under way to achieve the goal eagerly sought by Coca-Cola, PepsiCo, and others of 100% biobased PET. Micromidas is now commissioning a pilot plant for up to 1100 lb/day of biobased paraxylene. The company will report on its progress at the BioPlastek 2013 Forum on Bioplastics Today & Tomorrow, June 26-28 in San Francisco. The conference is sponsored by Schotland Business Research, Skillman, N.J.

It is offered in masterbatch form for ease of handling.

The new development marks SEFA's frst foray into plastics additives as part of its diversifcation strategy. Branded Permanix, this patent-pending, inorganic UV absorber reportedly features unique broad-spectrum UV absorbance from 200 to 800 nm, including the near-infrared, midinfrared, and far-infrared regions. It reportedly provides superior UV protection and permanence even in thin flms and coatings. It is composed of microscopic, spherical particles in the range of 0.5 to 10 microns. It is heat stable beyond 800 C, and can be dispersed readily in polyolefn and engineering resins. Moreover, it is not antagonistic to HALS (hindered amine light stabilizers), unlike conventional UV absorbers, and is also inert to agricultural pesticides and fumigants. Permanix is produced using proprietary processes designed for chemically treating certain post-industrial byproducts or other waste mineral matter and removing contaminants in or on those particles. Chemical treatment can add functional groups for synergistic or multifunctional properties in uses such as compostable flms. Natural-colored Permanix is compatible with colorants, and particles can be sized for use in thin flms or thick parts. 0.6 0.1% uV531 0.3% uV531 0.5% uV531 2% Permanix 10 1% Permanix 10 0.5 0.4 0.3 0.2 0.1 0 300 325 350 375 Wavelength, nm 400 425 450
