High Density Polyethylene Bottle Macro Encapsulated PCM

1, Features

• Macroencapsulation Phase change material bottles/Board

• Packaging Shell Material HDPE

• They can maintain constant temperature for long duration

• Variety of sizes/weights/colors available for option

• They are non-corrosive, They can be accommodated by microencapsulation and Microencapsulation containment solutions

• Encapsulation PCMs well controlled thermal energy release

• With Encapsulation, PCMs can be prevented the material heat exchange with environment

• Encapsulated PCMs can take protection against the degradation during heat uptake/ release cycles

• PCMs surface area and conductivity increased by utilizing encapsulation containment method

2, Descriptions

Our Encapsulated PCMs are available in forms of microencapsulated and macroencapsulated. Each is suited to particular applications.

First about our prime PCMs of SL,HC,TX,ME series,they are bulked known as unencapsulated,bulk PCMs may not suitable for use without prior encapsulation especially the soild-liquid SL series. Encapuslation in a shell material provides benefits such as protection of the PCMs from the external environment and increased specific surface area to improve heat transfer.The bulk PCMs is solid phase in ambient temperatures below its melting point and liquid in ambient temperatures above its melting point. Unencapsulated PCMs must be contained in forms either in micro- or macroencapsulation – before they can be integrated into a product

Microencapsulated: The process of coating small amounts of phase change material, from 10 to 1000 microns, is called microencapsulation. The three basic forms:

Powder: Particles of PCM are encased within a shell and immersed in a water solution. The water is then removed, leaving a powder of encapsulated PCM.

Cake: Particles of PCM are encased within a shell and then immersed in a water solution. Most of the water is removed, leaving a cake that is 30% water and 70% solids.

Slurry: Particles of PCM are encased within a shell and then immersed in a water solution. Some water is removed, leaving a slurry that is about 60% water and 40% solids.

Microencapsulated PCMs are sold to manufacturers for use in high-performance textiles, adhesives, bedding, flooring, paint, roofing and electronics.

Macroencapsulated: Phase change material contained in flexible films or plastic vessels of various size, shapes or formats is referred to as macroencapsulated PCM. Also known as bulk containment. Macroencapsulated PCMs are sold to manufacturers for use in cooling vests, car seats, warming blankets, electronics and thermal energy storage solution develops.
