Flexible and rigid polyurethanes foam are used in the bedding and furniture industry where its turned intomattresses & pillows, bath sponges as well as couch and sofa cushions. Recall that the recommended seam width for sealants - 6 mm (0.23 in), the maximum-optimal - 12 mm (0.46 in), the ratio of seam width to depth to 12 mm (0.46 in)- 1 to 1, over 12 mm (>0.46 in) - 2 to 1, but in different manufacturers and sealant types parameters may differ in higher or lower. Assumptions for simplifying the calculations are also not consistent. Dont have a recent invoice? wt.)
