Title:
TEMPERATURE-RESISTANT SILICONE RESINS
Document Type and Number:
Japanese Patent JP2019163481
Kind Code:
A
Abstract:
To provide elastomeric materials having improved temperature stability, longevity and robust mechanical performance for prolonged periods of time at high temperatures.SOLUTION: Methods and formulations for modified silicone resins of formula (II) are presented. (In the formula (II), R, R, R, R, Rand Rare each selected from the group consisting of H, alkyl, alkenyl, alkynyl and aryl; X is selected from the group consisting of arylene, transition metal, inorganic oxide, and silsesquioxane; and t ranges from 1 to 10, y ranges from 1 to 200, and z ranges from 1 to 1,000. Elastomeric materials prepared from the modified silicone resins display robust mechanical properties following prolonged exposure to high temperatures (e.g., 316°C or higher).SELECTED DRAWING: None
