Cold Weather Rubber (Dec, 1946)
Cold Weather Rubber
A rubber that doesn’t get hard and brittle at temperatures as low as sixty degrees below zero has recently been developed by the General Electric research laboratory. The new silicone rubber has any number of peace as well as wartime uses, due to its peculiar properties. The engineer shown above, clad in an electrically heated flying suit, demonstrates its flexibility in a laboratory testing chamber where the temperature is 60 degrees below zero.
