DESCRIPTION
Macrocapsule PCM’s, or macroPCM’s are large 3-mm spherical beads containing high concentrations of phase change materials developed by Microtek for use in cooling vests and garments. The PCM’s are low melting paraffin waxes, with melt points in the range of 0 to 50C that can absorb and release large amounts of heat.

The manufacture of the MacroPCM’s is protected under U. S. patents.

APPLICATIONS
The macroPCM particles are used to regulate the body temperature of individuals who work in hot environments, e.g. costume characters in theme parks or soldiers in a desert setting. The macroPCM’s absorb excess heat and permit the user to function for a longer time at a more comfortable temperature. The particles have been loaded into vests that are worn as an undergarment to allow for close skin contact.

PROPERTIES
The macroPCM capsules exhibit the following general properties:

• White to slightly off white color and a light blue color
• Round particles that are greater than 99% solids
• The macroPCM’s contain 80% effective PCM
• Particle size: Range of 1 to 4 millimeters depending on the size requested
• The density of the particles is slightly less than 1 g/cc
• The macro capsules have less than 1% free wax
