Product Overview


Phase Change Material

A phase-change material (PCM) is a substance with a high heat of fusion which, melting and solidifying at a certain temperature, is capable of storing and releasing large amounts of energy. Heat is absorbed or released when the material changes from solid to liquid and vice versa.


How does it work


shanghai goldenzen company is specised for phase change phenomenon of paraffin wax (PCM) for agriculture greenhouse

In recent years, with the world’s growing energy crisis, it has become an important issue to improve
energy efficiency and develop renewable energy.As an efficient energy storage material, our phase change
materials can store and use energy, be used in temperature control for greenhouse,and help to reduce the cost
of greenhouse production.
our phase change materials for agricultural house have good thermal behavior, no supercooled
phenomena and phase separation phenomena, and their physical and chemical properties are stable in the
long term use.The materials for agricultural greenhouse have a series of melting point. Their latent heats are
usually more than 210KJ/KG. Their criteria are as follows:

 Specific applications of the materials are mainly as follows:
The materials are made into solar energy automatic storage bags for green houses.By the radiation of
the sun in the day, the materials absorb a lot of heat, and store the heat in the latent heat of phase
change.When the temperature of the greenhouses are reduced, the energy stored in the heat storage
bags can automatically release the stored energy, which can improve the temperature of the
