The Micronal line, introduced in 2004, includes six paraffin-based PCMs offered in liquid and powder form, with melt points ranging from 21° to 26° C. Microencapsulated PCMs are used for thermal regulation in building and construction products, mattresses, textiles and packaging applications. Micronal is key component of building products such as Knauf Comfortboard and National Gypsum's ThermalCORE panels.
Manufacturing of Micronal products will be transitioned to Microtek’s Dayton production facility by the end of the year. Micronal products will be available through Microtek starting May 23.
"The Micronal line is a proven and established line of microencapsulated PCM products," said Microtek President Tim Riazzi. "Micronal can and has been used in many diverse market applications. Micronal is RAL-certified and meets the high expectations that Microtek and our customers demand. The Micronal product line complements the existing Microtek PCM product line by providing a complete suite of products for PCM customers."
BASF, based in Ludwigshafen, Germany, said the sale will allow its dispersions and pigments division to focus on its core business. The sale does not include Ludwigshafen production assets, BASF said, and no employees will be laid off. Marco Schmidt, Micronal's head of business management, will help with the transition for the next few months before assuming new duties at BASF.
Microtek says it has added personnel to handle the additional business and "will definitely be adding more" as the business grows. Riazzi says the company sees the need to add distribution points around the world and says a plan will be announced "very soon."
Microtek, founded in 1985, is a privately held company focused on phase change material and microencapsulation services. It introduced its Nextek line of PCM capsules in 2016.
U.S. patent application 20170137344 (applicant SABIC Global Technologies BV, Bergen op Zoom, Netherlands):
"An energy storage system is provided. The energy storage system includes a vessel made of a refractory material and containing a phase change material, a thermally insulating cover at least partially surrounding the vessel, an emitter, made of a refractory material, having a first side arranged to be heated by the phase change material and a second side intended to radiate thermal power, at least one photovoltaic cell arranged to receive the thermal power emitted by the second side of the emitter, and electric means for heating the phase change material."
U.S. patent application 20170138302 (applicant Innovation Management and Sustainable Technologies SA, Monterrey, Mexico):
"Disclosed is an energy collector system applicable to internal combustion engines. It may include: a) a collector of thermal energy from the exhaust gases; b) a thermal tank covered by helical tubes to gain heat by the exhaust gases; c) a heat exchanger; and d) an outer element capable of converting thermal energy into mechanical energy, such as a closed Brayton cycle turbine, a Stirling engine, a Rankine turbine or an open loop air motor for converting mechanical energy (coupling the difference in rpm) into electrical energy with an electrical generator. ... Thermal energy from the exhaust gases of combustion engines is collected in a thermal tank with phase change material to minimize the required volume and whose insulation minimizes energy losses."
U.S. patent application 20170138674 (applicant IFP Energies nouvelles, France):
"The present invention relates to an AACAES system and method in which a heat transfer fluid makes it possible to store heat. The heat transfer fluid, which comprises balls of heat storage material, circulates between two tanks: a hot tank and a cold tank, and passes through at least one heat exchanger. ... Advantageously, said balls are produced in alumina, in metal or by micro or nanocapsules of phase change material, such as paraffins, metals or salts."
• Warmilu, maker of the IncuBlanket infant warmer, reports that is on track for $300,000 in total 2017 sales after signing two distributors for Latin America, Africa and Southeast Asia: Relief for Africa Foundation and Maternova. The IncuBlanket, which has been successfully tested in clinical trials in India, uses packs filled with sodium acetate trihydrate to keep infants warm for up to five hours. CEO Grace Hsia says the device recently cleared its first regulatory filing with Kenya's Pharmacy and Poisons Board.
• Axiom Exergy has won a Gold Stevie for Energy Innovation in the 15th annual American Business Awards. Axiom's "refrigeration battery" enables supermarkets and food warehouses to store thermal energy at night when power is cheaper. The system, which uses salt-based phase change material, reduces peak power usage by up to 40 percent.
• Registration is open for IFAI's Expo 2017, set for Sept. 27-29 in New Orleans. The Industrial Fabrics Association International show will feature sessions on smart fabrics, military procurement, biomimesis and green certification.
• Pelican BioThermal has introduced a new Series 22 Universal system for its Credo brand of shippers. The system uses a dual PCM coolant system designed to be operational throughout the year.
• National Law Review offers a fresh overview of green chemistry laws across the United States. "State chemical control regimes," the authors conclude, "are likely to increase cost and foster confusion about chemical safety, which is one reason that Congress agreed to modernize TSCA by adopting LCSA."
• Monodraught's Cool-phase ventilation and cooling system was among the finalists honored at the National CSR Awards in London this week. The hybrid system, which won a "One to Watch" award, uses PCMs to store and release thermal energy, providing a free cooling load and reducing energy and maintenance costs.
• The agenda has been released for the 15th Cold Chain Global Forum to be held Sept. 25-29 in Chicago. Frank Butch, director of engineering at Sonoco ThermoSafe, will lead a master class on temperature assurance packaging certification.
• Bloomberg BNA is offering a free webinar June 12: "Reviewing New Chemicals under Amended TSCA: Impact on Innovation."
• Outlast Europe's Martin Bentz spoke with T.EVO magazine this month about the company's new Xelerate fabric (shown below). The fabric, introduced at a German trade fair earlier this year, incorporates "heat spreader" technology, a process traditionally known for cooling electronic devices. Xelerate fabric features improved thermal conductivity, Bentz said, and is suitable for home textiles, sportswear and protective gear. In an email exchange with Phase Change Matters, Bentz declined to discuss specific partners or customers.
