Abstract
A heat resistant silicone rubber composition containing greater than or equal to 0.1 mass % each of titanium oxide and iron oxide is disclosed. The heat resistant silicone rubber composition can form a heat resistant silicone rubber suitable for use in a high temperature environment. A method of reducing formaldehyde and/or low molecular weight organopolysiloxane generated from a cured product of a heat resistant silicone rubber composition upon heating the cured product is also disclosed. The method comprises compounding greater than or equal to 0.1 mass % each of titanium oxide and iron oxide in the heat resistant silicone rubber composition. Generally, even when the cured product is heated to a high temperature, such as a temperature greater than or equal to 300° C., generation of formaldehyde and/or low molecular weight organopolysiloxane (e.g. D4, D5, and D6) from the cured product can be reduced.
