RT507F Silicone Tube – Superior Heat & Arc Resistance

RT507F is manufactured using a fine weave glass fabric combined with a silicone resin system. It has excellent electrical properties under humid conditions, superior heat and arc resistance. The fine weave fabric substrate provides a “finer” finish on the surface of the finished part. RT507F also complies with MIL-I-24768/17, Type GSG and ASTM D709 Type IV Grade G-7 and IEC 61212-3-1 SI GC 21.
