Initial Compounding Studies of Polyphosphazene Rubber
ARMY NATICK LABS MA CLOTHING AND PERSONAL LIFE SUPPORT EQUIPMENT LAB
Polyphosphazene rubber, a new elastomeric material, was compounded with various curing agents and evaluated for fuel resistance, low temperature flexibility and general physical properties. The compounding studies showed that the polymer is curable with dicumyl peroxide in the presence of magnesium oxide. Testing showed that the polyphosphazene is a nonflammable material with an excellent combination of fuel resistance and low temperature properties. Its physical strength is weak but future polymerization work and improved compounding techniques may produce desired strength and provide a material suitable for use in Army applications.
