In this paper we present the heat-resisting properties of a hybrid made from poly(dimethylsiloxane) (PDMS) and tetraethoxysilane (TEOS) through a sol–gel reaction. It is found that the hybrid with ratio $\text{TEOS/PDMS} = 10$ shows a weight loss of less than 3% after aging treatment at 200 °C for 480 h in air. The reason for the good thermal endurance property is that low-molecular-weight PDMS chains bond to the surfaces of silica derived from TEOS, leading to the suppression of the thermal decomposition of the chains. After the aging treatment, the mechanical properties of the elastic modulus and breaking stress are improved and elongation at breaking decreases. It is also found that the electrical insulating properties are stable upon aging treatment.
