Aegis Phase
Change Materials come in various specific temperatures varying between
-30°C
to + 90°C. These
can be classified into two categories: organic and inorganic. Organic
phase change materials generally consist of various paraffins, waxes,
and alcohols, while inorganic phase change materials are primarily
hydrated salts. In addition, a variety of encapsulation techniques
have been developed for use in numerous applications and include
HDPE panels, HDPE spheres, multilayer pouches and pads.

Encapsulation
Specifications
HDPE profiles/Panels
HDPE Panels have been exclusively designed in different
dimensions and capacity. These rigid profiles have
cavities filled with PCM. The panels should be installed
in a horizontal plane with angular mounting to provide a
high value energy saving supplement to proprietary thermal
management systems.
HDPE/PP Spheres
By encapsulating PCM into small spherical rigid balls, the
properties and benefits of PCM can be gainfully utilized
for applications like boilers, solar water heaters, room
heaters etc.
Multilayer Pouches & Pads
This is most flexible mode for PCM packaging. The material
used for these pouches are multilayer films (PET/Aluminum/PET)
used to impart strength, durability, and integrity. These
PCM pouches may be utilized in material transportation containers
for temperature sensitive goods, apparel, and hot pads as
well as be utilized within central air conditioning ducts
and false roofing of commercial complexes.
