TFP has developed new lightweight veils designed for high temperature performance in composites.

The polyimide and basalt veils will form part of the company’s Optiveil range.

According to TFP, the polyimide veil is the highest temperature stable polymer veil that it makes, with a maximum service temperature of above 260°C – higher than other polymers such as polyester and polyphenylene sulfide (PPS). The material was developed as an insulation material for space applications, designed to offer the temperature stability necessary to withstand missions to Mercury and the Sun, where spacecraft experience extreme temperatures.

The company’s basalt veil is reportedly stable up to 850°C and retains its integrity when in contact with an open flame, making it suitable for applications requiring a fire barrier. Basalt, like glass, also has a high resistance to acid and alkali, which makes it suitable for use in corrosive environments.

TFP will be showcasing the new materials at JEC World.
