德国 Kerafol KERATHERM GFL 3020 GFL3030 GFL 3040 – silicone elastomers 双组分导热胶
德国 Kerafol Keratherm GFL3020 GFL3030 GFL3040 是一种陶瓷填充、无溶剂的双组分有机硅弹性体。由于**的的导热性、可压缩性特性以及良好的介电性能，这些填缝剂非常适合封装或点胶，有效提高批量生产效率。
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.
