Abstract
The present disclosure relates to a phase change material (PCM) composition and a process for preparation thereof, wherein said composition comprising a phase change material, glass fibers and xanthan gum. In a preferred embodiment, the phase change material is water (or ice) and the g lass fibers are glass wool. The disclosure also relates to a stackable and sealable package enclosing the PCM composition. In a particular embodiment, the PCM composition is used to prepare a cold box that may be used in cold chain transportation.
Claims20
A phase change material (PCM) composition comprising:
- a. a phase change material,
- b. glass fibers and glass microparticles, and
- c. xanthan gum.
A stackable, sealable package enclosing a phase change material (PCM) composition within said package, wherein the PCM composition comprises:
- a phase change material,
- glass fibers and glass microparticles, and
- xanthum gum;
- wherein said package further comprises at least one three-dimensional support structure inserted therein, said at least one three-dimensional support structure being conformed to the dimensions of the package to thereby provide a fixed geometrical shape to said package.
A method of preparing a phase change material (PCM) composition comprising:
- a phase change material,
- glass fibers and glass microparticles, and
- xanthan gum;
- wherein the method comprises:
- a. providing the PCM in a solid state;
- b. adding to the solid PCM, glass fibers, glass microparticles and xanthan gum, and optionally a polyacrylic salt;
- c. changing the PCM into a liquid state to thereby form a liquid mixture comprising the PCM and said additives;
- and
- d. agitating the liquid mixture obtained from operation c to form the PCM composition.
An insulation layer comprising at least a stackable, sealable package enclosing a phase change material (PCM) composition within said package, wherein the PCM composition comprises:
- a phase change material,
- glass fibers and glass microparticles, and
- xanthan gum;
- wherein said package further comprises at least one three-dimensional support structure inserted therein, said at least one three-dimensional support structure being conformed to the dimensions of the package to thereby provide a fixed geometrical shape to said package, where said package is coupled to at least one additional layer of glass microparticles, which are vacuum sealed in a packaging material.
An insulation device comprising a phase change material (PCM) composition comprising:
- a phase change material,
- glass fibers and glass microparticles, and
- xanthan gum.
