Hi List,

Just picked up my new g10 disks for my srsg, they gave me a
spec sheet that I will list below for those interested.

sample thickness 0.125", (3.2mm).

Tensile Strength      Lengthwise  65,000 psi
                      Crosswise   49,000 psi

Flexural Strength     Lengthwise  84,800 psi
                      Crosswise   66,100 psi

Compressive Strength  Lengthwise  43,000 psi
                      Crosswise   42,200 psi
                      Flatwise    48,500 + psi

Water Absorption                  0.08% by weight
Specific Gravity                  1.87
Flammability (UL90)               94VO
Dielectric Strength               488 Vpmil (20KV/mm)
Dielectric Breakdown              80+Kv
Arc Resistance                    126 seconds
Comparative track index (CTI)     440 Volts
Dissipation Factor, 1khz          0.005

Temperature ratings for above properties are -50C to 155C.

And it's also available in TUBES :-)    4.75mm ID to 250mm OD x 915 mm
