This is a heat dissipation material that achieves no silicone, high thermal conductivity, low specific gravity, insulation, and low wear resistance. It is used in mass production for electric vehicle batteries!
Politec PT is based in Germany and is mass-produced as a heat dissipation material for EV/HEV lithium-ion batteries, adopted by vehicle manufacturers in Europe and Asia. Since it does not use silicone, there are no concerns about low molecular siloxanes gasifying and adhering to electronic substrates, causing contact failures even at high temperatures. Additionally, by not using non-degradable silicone, it is also environmentally friendly. It possesses the necessary thermal conductivity for batteries, lightweight due to low specific gravity, and excellent insulation properties. Based on our past mass production achievements, we can provide economical material proposals. Furthermore, due to its low wear filler, it is gentle on dispensers, reducing maintenance costs and downtime for equipment. Custom designs are also possible according to customer requirements. We offer free samples, so please feel free to contact us. 【Features】 ■ Proven performance in EV/HEV applications ■ No silicone used ■ High thermal conductivity (2.0~3.5 W/mK) ■ Low specific gravity (2.0~2.7 g/cm3) ■ Insulation (6~10 kV/mm) ■ Economical material proposals available ■ Low wear filler ■ Proposals for process automation using dispensers are possible
Inquire About This Product
basic information
Polytech PT "Thermal Conductive Gap Filler" is available in two types: one-component non-curing and two-component curing. Both are non-adhesive, allowing for the removal and recovery of lithium-ion batteries. ■ One-component non-curing type: No separation, no spillage, no shifting. Being a one-component product makes it easy and economical. ■ Two-component curing type (mixing ratio 10:1): Even with reduced viscosity to improve application, there is zero concern about pump-out. ■ Non-adhesive: Due to the lack of adhesive properties, it allows for the removal and recovery of lithium-ion batteries. ■ Continuous use temperature (-40 to 85°C): If you wish to use it temporarily beyond this temperature range, please contact us. ■ We will propose solutions considering material properties, cost-effectiveness, and application based on customer custom requirements. *For more details, please refer to the materials. Feel free to contact us with any inquiries.
