CINI 2013 Compliance Results
CINI is the dominant international standard governing insulation in Liquid Natural Gas (LNG) facilities. Dyplast's ISO-C1/2.5 (2.5 lb/ft3) meets or exceeds the requirements of this most demanding standard.

1 In cryogenic and cold services increased contraction stresses occur in the insulation materials. Therefore an increased tensile strength and a reduced tensile modulus and linear thermal expansion are required. This is formulated in a safety factor. At service temperatures below - 50°C, the cryogenic thermal stress resistance (CTSR) factor of the PIR insulation foam shall comply in the X, Y and Z direction with the following equation:
