Open and closed cell polyurea foams
An open cell spray polyurea foam for use in an insulation layer in a wall structure may include a polyurea. The polyurea may be a reaction product of an isocyanate compound and water. The open spray polyurea foam may also include a filler. The majority of the filler may exist in the spray foam formulation as an unreacted first fire retardant. The spray foam formulation may further comprise a second fire retardant, and the insulation layer may exhibit a fire retardancy sufficient to pass Appendix X and/or ASTM E-84.
Methods for Reactive Three-Dimensional Printing by Inkjet Printing
Methods of printing a three-dimensional object using co-reactive components are disclosed. Thermosetting compositions for three-dimensional printing are also disclosed.
HYBRID NOVOLAC POLYUREA/POLYURETHANE
A hybrid polyurethane/polyurea polymer suitable for forming a coating on a structure which is in contact with water includes the reaction product of a polyol component consisting of one or more polyols, a polyamine, and a curing agent, such as a polyisocyanate. The polyol component includes a Novolac-type polyether polyol.
AUTOMOBILE PARTS
The object of the present disclosure is to provide an automobile part capable of improving fuel consumption by weight reduction of the part because the impact resistance that can be sufficiently used even in cold regions can be given to a part made of a thinner plastic.
