Description:

The glass transition temperature (Tg) is an important normative dimension for the base material that determines the temperature at which the resin matrix converts from a glassy, brittle condition into a soft, elastic one.

The Tg value of the base material sets here an upper boundary, at which the resin matrix decomposes and a subsequent delamination occurs. The Tg is thus not the value of the maximum operational temperature, but rather that which the material can endure for only a very short time. A guideline for a continuous thermal load is an operating temperature approximately 25°C below the Tg.

When the glass transition temperature (Tg) is over 170°C, it is referred to as a high Tg material. We also call it TG170 board.

High Tg materials have the following properties: 

· high glass flow temperature value (Tg) 

· high temperature durability 

· long delamination durability 

· Low Z axis expansion (CTE)
