VA809 SIC RAPID COOLING ANTI-BENDING ROLLER
Combined the silicon carbide and alumina, the VA809 roller has excellent performance in physical strength and thermal conductivity. The roller does not bend in critical thermal shocks. VA809 solves the problem of heaping up and irregular moving of ceramic tiles due to the bending of roller in rapid cooling zone.
