Gap filler/thermal grease for EV/HEV lithium-ion batteries
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!
Polytech 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 previous mass production track record, we can offer 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. Free samples are available, 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 ■ Automation proposals for processes using dispensers are possible
basic information
The 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 single component makes it easy and economical. ■ Two-component curing type (mixing ratio 10:1): Even with reduced viscosity for better application, there is zero concern for pump-out. ■ Non-adhesive: Due to its non-adhesive nature, it allows for the removal and recovery of lithium-ion batteries. ■ Continuous use temperature (-40 to 85°C): Customers wishing to use it temporarily outside this temperature range are encouraged to 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 documentation. Feel free to contact us with any inquiries.
