Title:
TEMPERATURE-RESISTANT SILICONE RESINS
Document Type and Number:
Japanese Patent JP2016020485
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: 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 (I) are presented, where R, Rand Rare each independently selected from a group consisting of H, alkyl, alkenyl, alkynyl, and aryl; n ranges from 1 to 10; m ranges from 1 to 200; and p ranges from 2 to 1,000. Elastomeric materials prepared from modified silicone resins indicate robust mechanical properties following prolonged exposure to high temperatures (e.g., 316°C or higher).SELECTED DRAWING: None
