     --Matching ratio is based on the optimal matching value which will vary with the category and additive amount of paint additives added. --Free foam density will vary with the seasons (temperature, humidity). --Stripping time will be extended with the increase of the thickness of moldings. --Folding endurance conditions: bending angle is 90 degrees and the frequency is 80 times / min * 40 thousand times --Data listed above is just for reference. The specific data is subjected to the practical operation. If other physical properties are required, please contact us.
