德國 Kerafol KERATHERM GFL 3020 GFL3030 GFL 3040 – silicone elastomers 雙組分導(dǎo)熱膠

德國 Kerafol Keratherm GFL3020 GFL3030 GFL3040 是一種陶瓷填充、無溶劑的雙組分有機(jī)硅彈性體。由于**的的導(dǎo)熱性、可壓縮性特性以及良好的介電性能，這些填縫劑非常適合封裝或點(diǎn)膠，有效提高批量生產(chǎn)效率。

Kerafol KERATHERM GFL 3020 GFL3030 GFL 3040 Gap Filler 

Ceramic-filled, solvent-free two-component silicone elastomers. Due to their various thermal conductivities, their different compressibility characteristics as well astheirgood dielectric properties, these Gap fillers are ideally suitable for encapsulating or dispensing. A wide range of different material viscosities makes them suitable for“wet-in-wet”production.
