Welcome to Chooyu
Chooyu, one of the most innovative companies in the world, was founded in 2006 by a group of scientists in the United States. In its short history, the company has become a prominent player in silicones, silicon-based technologies focusing on thermally conductive materials for various industries, such as consumer electronics, LED lightings, industrial power supplies, solar solutions, telecommunications as well as automotive industry.
On the path of Chooyu’s growth trajectory, an array of world renowned companies has been enlisted as Chooyu’s customers. We are proud of what we do, especially our innovations –Chooyu’s two component potting compoundhas the world highest thermal conductivity; the most plastic like thermally conductive plastics with highest thermally conductivity and elasticity.
Chooyu has established its manufacturing base in China, close to the OEM factories for the world. This allows us to provide our high quality products with the lowest cost to our customers. Chooyu applies a stringent set of operation standards to its production lines. We are an ISO9001:2008 certified company.
A List of Industries We Serve
|LED lighting||Power/Green Energy||Telecom/Compouter||Industry and Automotive|
PAKCOOL® PAKCOOL® TPP-8130, TPP-7130 are insulated thermally conductive plastics with high thermal conductivity(15w/m*K per ASTM E1461),high strength and excellent flexibility (with Nominal Strain @ Break of 7%), designed for LED lighting market and electronics devices. TPP7130, TPP8130 can meet the requirements of most LED manufactures. TPP7130 is based on PA66. It has been modified with thermal conductivity and flexibility. Besides the LED bulb heat sinks, TPP7130/8130 can be used in plastics cases for power adapter, UPS and other devices that need insulation and heat dissipation.TPP-8130 is based on PP. The modification type of TPP8130 has been improved with great tensile property, and is the first insulated thermally conductive plastic that can be used for extrusion processing. Used in LED tubes to replace aluminium heat sink, it can be more safe and helpful in heat dissipation.
|In order to provide reference design for customer in using TPP7130/TPP8130, Chooyu developed a heat sink cup for A60 LED bulb, and assembled with LED boards & LED driver for testing. The result are that the temperatures of soldering point of LED components are 63?C, 67?C and 73?C corresponding to 7w, 8w and 9w LED module respectively. for more detail information, you can check The testing result for Chooyuchem'A60 LED bulb heat sink with (7w/8w/9w) on LED board for requiring chooyuchem A60 heat sink sample to do testing, please contact with Chooyuchem sales|
