Description of Platinum Cure Silicone Foams Platinum Cure Silicone Foams is a soft, two-component platinum silicone flexible foam that is versatile and easy to use. HY-F663 Platinum Silicone Foams expands 3.5 times its original volume and develops a uniform 20 lb./cu. ft. cell structure (320 kg/m3). Vibrant colors can be achieved by adding Silc-Pig*silicone color pigments. Cured foam is high heat resistance (will resist up to 350,°F/176,°C), water resistant, UV resistant and resists oxidation and ozone degradation. Typical Applications for Platinum Cure Silicone Foams Platinum cure Silicone Foams can be used for a variety of industrial and special effects applications including making foam filled appliances, padding/seat cushioning, orthotics/orthopedics, potting and encapsulation of electrical circuits and vibration dampening.
