Thermal gap filler materials is used to fill the gaps or spaces between objects. In the field of engineering and manufacturing, gap fillers are often used to fill the gaps of electronic devices, automotive parts, battery components, etc. to improve heat dissipation efficiency, prevent vibration, prevent dust or liquid from entering, or improve the stability and sealing performance of mechanical structures. The state of thermal conductive gap filler when extruded is a paste similar to "cream". It can be squeezed and scraped at will during its operating time. Its shape can change with external force. The purpose is to fill the gap as much as possible and exhaust the air.
The mechanism of action is to fill the interface of the electronic device with a liquid polymer that has not yet cured, either manually or automatically. Thus achieving maximum fit between the two interfaces and reducing voids. The material generates almost zero stress on the component. It can be used to join and apply complex surfaces. We also offer dispensing equipment to further help our customers establish an optimized dispensing process and provide a total solution.
In new energy vehicle battery components, gap filler with high thermal conductivity automotive play an important role, especially in the battery pack assembly process. The battery pack is composed of multiple battery cells, and there will be some gaps between the cells and between the cells and the shell. These gaps may affect the heat dissipation and stability of the battery, so it is necessary to fill the gap with a suitable gap filler to optimize the assembly and performance of the battery pack.

Q: Why choose Non Silicone Gap Filler?
A: Environmental factors: Modified silane thermal conductive gap fillers are more environmentally friendly than silicone gap fillers and do not contain environmentally harmful silicon compounds. Under the current trend of emphasizing sustainable development and environmental protection, car companies and battery pack manufacturers tend to choose more environmentally friendly gap fillers to reduce or even avoid the volatilization of small molecules of silicone. For gap fillers in new energy vehicles, if they contain silicon components, they need to be evaluated and regulated according to the relevant requirements of REACH to ensure that they meet the EU's chemical safety standards. In addition, the EU may encourage or promote the use of more environmentally friendly and safer alternatives to promote the sustainable development of new energy vehicle technology.
EU REACH compliance, this regulation was formulated by the European Chemicals Agency (ECHA) of the European Union (EU) and came into effect on June 1, 2007. The adoption of this regulation aims to improve the level of protection against human health and environmental risks that may be caused by chemicals.
Industry trends and Requirements: With the rapid development of the new energy vehicle market, car companies and battery pack manufacturers have put forward higher requirements for the safety, reliability and performance of battery components. Selecting high-quality non-silicone thermally conductive gap fillers can meet these requirements and conform to industry development trends.
