SM 40 Transparent – high-quality semitransparent silicone rubber sheets made in EU from high performed components. Silicone membranes SM 40 is optimal combination of strength and elasticity. The vacuum membranes has high working temperature till 200 C and elongation till 700%. The high temperature resistance allows use membranes in solar and glass industries as also for shaping of composites materials (solid surfaces, acrylic materials). The silicone membranes supplied with smooth finish.
