Physical characteristics: from low to high temperature -60 ℃ ~ +280 ℃ wide temperature range, the experiment proved that the material at high temperature of 250 ℃ case, continuous for 200days, not reduce the strength, weight will not reduce;placed in a high temperature of 350 ° C for120 hours, the weight reduction of only about 0.6%. Conversely at -180 ℃ ultra-low-temperaturecase will not lead to cracking and maintain the original softness;

2, non-adhesive: paste, resin, paint almost all of the adhesive material can simply remove;

3, the mechanical characteristics: withstand the compression load does not deform the basic lack ofvolume, dimensional stability coefficient of friction is low, almost not exist elongation;

4, electrical insulation: a unique electrical insulation is extremely superior dielectric constant of2.60, the dielectric loss tangent of 0.0025
5, the chemical resistance: against the vast majority of pharmaceutical items.
