XK-S25 is a high performance, thermally conductive, eletrically insulation gap filling material. It is ideal for fragile part with low or no stress on compnent. It cures at room or elevated temperature. after curing, it forms elastomer for easy maintenance. It suitable for filling variety of different gap thickness with low compressive forces.

GLPOLY Thermal gap filler has been applied to drivers, keeping devices performing at their best .

On the market, there is a range of thermal gap fillers. But the quality of products varies considerably, you will feel that it’s not easy to purchase a suitable thermal gap filler to improve thermal management of your electronic devices. Here is a case I experienced last year.

Mr. Wang was the purchasing manager from a driver manufacturing company, he used to purchase Gap Filler 2000 as thermal interface material for driver products. Last year, customer wanted to change material due to COVID-19 epidemic leading to rise in price of raw material and logistics delay, he wished to cooperate with a local supplier for reducing cost and logistics complexity.

He said he had tested several samples for different suppliers, but was not satisfied with test results either high viscosity or poor performance. we knew that if we achieved a higher performance, more thermally conductive fillers was needed thus increasing the viscosity causing dispensing difficulty. If they made dispensing process more smoothly, they needed to fill less thermally conductive fillers thus decreasing thermal performance. To competing against gap filler 2000, GLPOLY has launched a thermal gap filler-XK-S25 with 2.5W/mk of thermal conductivit. The 210,000Cps viscosity makes dispense process smooth. As a perfect alternative to GF2000, I recommeded XK-S25 thermal gap filler to customer. He was satisfied with the technical data and was willing to test the properties of XK-S25.

The high temperature ageing test lasted for two months. One day, Mr. Wang called me and said his team had finished the test, and were satisfied with the results. Change of indexes before and after ageing test were within tolerance. Besides exceptional performance, GLPOLY’s 14-day lead time and 70% of the price of GF2000 were attractive to customer, you can not find another one in China. Our cooperation brought customer great benefits.

Advantages and benefits of XK-S25 thermal gap filler are as following:

1. Compatible with high volume, automated dispense processes, decreasing installation csot;

2. Particle size of thermally conductive fillers will be decreased by nano-scale grinder to improve heat transfer;

3. Proven reliability under extreme temperature cycling;

GLPOLY has been committed to developing thermal interface materials for 18 years, and partnered with DT Mobile, Vinfast, LG, DJI, Han’s Laser, GAC Motor, NIO Motor and more, providing them with exceptional performance thermal interface materials, comprehensive support and time-tested knowledge to solving thermal management challenges.

GLPOLY XK-S25 thermal gap filler is equivalent to imported products, such as Gap Filler 2000. This material has been applied to drivers, motors EV batteries, such as Xiaokang Motor, Lixiang Motor, Farasis Energy, Welling Motor etc:

1. GLPOLY has introduced nano-scale grinding machine to decrease particle size by 30%, improving contact between particles, optimizing heat transfer, no peers would do this;

2.  Mix ratio ”1:1”by volume. Suitable for automated dispense process;

3. Ideal for uneven topography, deforms under low compressive force, decreasing stress on component;

4. Cures into sheet, in place of thermal gap pad;

5. Accommodates a variety of bond line thickness to multiple devices;

6. Proven reliability under low and high temperature thermal cycling, prediction service life for more than 10 years;

GLPOLY has introduced robotic production lines to improve consistency of products and eliminate human error. Furthermore, GLPOLY is the first one, maybe the only one to adopt nano-scale grinding machine to process fillers for decreasing particle size and achieving better contact between partilces, thus improving heat transfer.

1. GLPOLY is the designated supplier of Huawei, DJI, NIO Motor and more; More than 30 items can be tested in-house, and third party verified;

2. Improves raw material quality from its source, it’s hard to achieve for rivals;

3. Mixed by automatic preparation and distribution system for measurement accuracy of 3‰, rivals can not achieve it;

4. Automatic production process eliminates human error, and most rivals in China adopt manual mixing;

5. Developed simulation design and test software, improving development cycle; Accelerated high temperature aging test approved by Institute of High Energy Physics

6. Formulates one-to-one dispense program and delivers assembly pressure simulation;
