100% borosilicate glass. Borosilicate glass is rated for higher temperatures than normal sheet glass. Flat, heat resistant plate. Does not warp during long term use..
Conducts heat evenly across the build surface to ensure consistent temperature throughout the build surface.
High binding power when heating. Easy to separate the plastic parts when cooling.
Make you out of the trouble when plastic film decreased viscosity after a period of usage.
