Splet09. apr. 2024 · Thermal decomposition PDMS is characterized by a low rate of heat release; generally in the range of 60–150 kW·m 2 [ 7 ]. It should be emphasized that the combustion of silicones is not accompanied by the release of any toxic or aggressive gases. In addition, a very small amount of smoke is emitted [ 8 ]. british open wager lowest score
