GYC Nano Heat Conduction & Radiation Additive Material

Description

Intro

GO YEN CHEMICAL INDUSTRIAL CO., LTD. (GYC Group) technical department have developed that coating heat conduction material means plastic products with higher heat conductivity.  Normally, the heat conductivity will be 1W/(m∙K), and we will think of mental when we talk about material with excellent heat conductivity.  Not only mental possess prominent heat conductivity but also can be applied on radiator, heat exchange material, waste heat recycling, brake component, printed wiring board.   However, mental is too heavy to hinder to make light products and electronic items.  Besides, worse anti-corruption and difficult to mold are the fatal defects to mental.  These shortcomings limit the application to mental.
Basically, both engineering plastic and alloy plastic own good anti-corruption and mechanical properties, but the poor heat conductivity can’t be modified for a long time, HDPE is a better heat conduction material still possess only 0.44W/(m∙K) heat conductivity, it also limit the application of plastic.   
To solve problem of worse heat conductivity, GYC especially developed  Nano heat conduction& conductivity material to improve this question,  compound plastic with high heat conductivity material can raise the conductivity of plastic.  This revolutionary material can expand the application in plastic filed.

 

Theory of GYC Nano heat conduction& radiation additive material

 –take resin for example

Take resin matrix for example, heat conductivity depend on the orderliness of crystal lattice structure.  Crystal lattice structure resin with good orderliness and outstanding crystallinity would possess higher heat conductivity, and vice versa.   The temperature higher and the conductivity of resin would become higher.  However, there still some difference between distinct resin, take amorphous resin for instance, heat conductivity will rise rapidly and then become gentle, then it will rise again.   Taking semi-crystalline for instance, heat conductivity will rise rapidly and then rise slowly.  Take crystalline resin for instance, heat conductivity will rise to peak and decline slowly.  In addition, molecular weight, cross-linking and orientation of resin can also affect heat conductivity.  The most importantly, adding GYC Nano heat conduction & radiation to resin matrix with high crystallization is the most effective way to raise heat conductivity.  Please see the below examples.
