BRANDENBURGER BRA-GLA® 3 was developed especially for the wide range of requirements in the manufacturing of tools and dyes, and consists of a combination of high-quality thermoset resin and fine glass fibers.
Special material characteristics:
- Very High Dimensional Stability
- Good Insulation Properties
- Very High Compressive Strength
- Coefficient of Expansion Similar to that of Steel
Areas of application:
BRA-GLA 3 is mainly used as heat protection for injection moulding machines, as well as on presses, as piston and frame insulation.
With its high e-module, low mass dissipation when exposed to thermal stress for long periods and expansion properties similar to that of steel, BRA-GLA® 3 is suitable for many machine engineering applications; e.g. blow-moulding machines, as well as packaging and extrusion systems.
Its very high dielectric resistance makes it also suitable for switch cabinet and apparatus engineering.
