Key Features
High Strength
G10 (T311) is known for its exceptional mechanical strength, making it ideal for use in demanding environments. It’s rigid, durable, and resistant to wear.
Electrical Insulation
One of the standout features of G10 (T311) is its electrical insulating properties, which make it suitable for electrical and electronic applications.
Heat Resistance
G10 (T311) can withstand relatively high temperatures (usually up to 130-150°C), though it is not as heat-resistant as some higher-end materials like ceramics.
Moisture Resistance
It has low moisture absorption, which ensures stable performance in humid environments and maintains its integrity even under high humidity.
Lightweight
G10 (T311) is lighter than some other materials like metals, making it ideal for applications where weight is a concern.
