<p>Silicone rubber sheet contains pref. several layers of mouldable nonwoven fabric, pref. spun fibre mat of polyolefins with max. 6C, esp. polyethylen or polypropylene, with a mass of 5-80, esp. 10-40g m2. The sheet should have almost the same tensile strength and elongation (to DIN 53 857) and tear propagation strength (to DIN 53 859) in the longitudinal and transverse directions of the mat. The sheet is suitable for deep drawing and may be weldable. It can be made into seals, sealed containers and other mouldings.</p> |
