Scott Bader initially approached a number of independent materials test houses, who were unable to accurately measure the heat deflection temperature (HDT) and the thermal decomposition temperature of Crestapol 1234; conventional test equipment for composites resins couldn't measure values above 300°C and the performance of Crestapol 1234 was found to go beyond this maximum test measurement range.
Tests were finally carried out by two different accredited test houses. The HDT testing was carried out by Intertek Plastics Technology Laboratories, Massachusetts, USA, who measured the HDT of Crestapol 1234 to be in excess of 300°C. The thermal decomposition temperature was measured by Gearing Scientific, Cambridge, UK, who recorded the thermal decomposition temperature for Crestapol 1234 at 330°C in air and 340°C in inert gas. Post curing at temperatures above the resins standard 200°C post cure temperature does not affect the decomposition temperature.
Crestapol 1234 resin is being commercialised with a range of viscosities suitable for manufacturing filled and reinforced composites parts by hand lay-up or closed molding, with a gel time (2G:2LPT at 25°C ) of 16 to 17 minutes. Potential new industrial applications for this ultra high temperature resin are expected in markets such as aerospace, automotive, electrical & electronics and oil & gas.
