China Standard: 3640
NEMA Standard: FR4, G11
IEC Standard: EPGC21, EPGC22, EPGC23
3640: with higher mechanical and electircal insulating property, low water absorption, used for the insulating structural parts
for electric apparatus.
FR4, G11 Tube: FR4 tube with flame retardant property, and G11 tube has higher thermal endurance property.
Both have much higher mechanical strength, better dielectric loss properties, and excellent electric
strength properties under any conditions such as dry and humid environment.
EPGC21, EPGC22, EPGC23: EPGC21 usually used in the mechanical, electrical and electronic applications. It can keep
the stable electrical insulating property under heavy humidity. EPGC22 similar to EPGC21, it has better
mechanical property under high temperature. EPGC23 similar to EPGC21, but it has the fire retardant
property.
