PureTemp phase change materials are designed to absorb and release large quantities of thermal energy at specific temperatures. Twenty-three PureTemp PCMs have been designated as 100 percent biobased by the U.S. Department of Agriculture's BioPreferred program. Our proprietary formulations and patented manufacturing processes yield superior results at cost-effective prices. See technical details on each PureTemp product.
PureTemp-treated fabrics provide an effective buffer against ambient temperature swings. In consumer products such as jackets, pillows and gloves, the PCM-enhanced fabrics interact continuously with the unique microclimate of the human body, storing and releasing heat to balance body temperature and increase comfort in any climate, any time. Our material, derived from sustainable sources such as plant oil, is nontoxic and biodegradable.
PureTemp phase change material is now available in macroencapsulated form. These innovative Vesl containment devices have an enhanced surface-area-to-mass ratio. This means faster energy exchange and enhanced performance of the PCMs inside. Vesl products come in many shapes, sizes and temperature ranges and can be adapted to fit your specific requirements.
Stackable blocks to build your solution
The BlockVesl is a precisely engineered duct plate of specially engineered plastics designed to contain phase change material and efficiently transfer thermal energy. Whether stacked together, used to line the wall of a container or for another purpose, the BlockVesl is ideal for cold storage, refrigeration, air conditioning, heat recovery and heat storage.
These sturdy TubeVesls are hermetically sealed and able to withstand extremely high temperatures. Each holds 100g (3.5 ounces) of the PCM of your choice.
Flexible in every way
Designed for a wide variety of applications, these MatVesls are multi-layer barrier film packages, hermetically sealed and able to withstand long-term use. This sample is 11 inches x 42 inches, each weighing approximately 1 kilogram (2.2 pounds). Contact us for information on custom sizes.
The process of coating small amounts of phase change material, from 10 to 1000 microns, is called microencapsulation.
Microencapsulated PCMs are sold to manufacturers for use in high-performance textiles, adhesives, bedding, flooring, paint, roofing and electronics. Contact one of our containment partners, Encapsys or Microtek Laboratories, for information on microencapsulated PureTemp.
