PCMCOOL - Ru Entropy

A leading China PCM manufacturer

Who We Are

Founded in Shanghai, 2014, RU Entropy is a thermal management technology and product company focused on Phase Change Materials (PCM) and practical thermal management solutions.

We develop and supply PCM-based materials, thermal cores, modules and finished products for applications where temperature needs to be managed more precisely.

Our approach

Material Thermal Core Module Product Solution

Our goal is not simply to sell PCM. We help customers translate thermal requirements into practical products through PCM technology, product development and manufacturing support.

Our Core Philosophy

Cooling is not simply about making something cold. Different applications require different temperatures, durations, energy capacities and product designs.

We design around:

Temperature, Duration, Thermal Energy, Geometry, Comfort & Flexibility, Packaging & Application
