18℃,5℃,0℃,-10℃,-15℃,-21℃,-25℃ Phase Change Material Cold Storage Agent

Description

Brief Introduction

A phase change material (PCM) is a substance which releases/absorbs sufficient energy at phase transition to provide useful heat/cooling. Generally the transition will be from one of the first two fundamental states of matter – solid and liquid – to the other.

Specification

We offers the phase change cold storage agent from 18℃ to -25℃. The detailed specification is in the table below:
