    Ben Welter - Wednesday, January 07, 2015

    The global market for advanced PCMs is projected to reach $1.47 billion by 2019, according to ReportsnReports.com. That's a compound annual growth rate of more than 20 percent over the next five years. The market for thermal energy storage PCMs is projected to register a CAGR of 22 percent in that period.

    "Organic PCM are projected to have the higher growth rate than inorganic PCM due to the higher prices and ease of microencapsulation for organic PCM," according to the report.

    Trend toward smart textiles is driving growth in microencapsulated PCMs

    Ben Welter - Tuesday, December 09, 2014

    The latest Frost & Sullivan research on the global market for microencapsulated phase change materials in textiles and mattresses is out. F&S reports that the industry earned revenues of $45.1 million in 2013 and projects that number will reach $99 million in 2018.

    The report covers fibers, yarns, fabrics, foams and gels that incorporate microencapsulated PCMs. F&S says the trend toward smart textiles that comfortably regulate temperature is driving the use of microencapsulated PCMs in clothing and mattresses.
