Abstract: The disclosure belongs to the technical field of heat insulation materials, and discloses an in-situ microfibrillated reinforced polymer composite heat insulation foam material as well as a preparation method and application thereof. This disclosure adopts a polypropylene matrix, a fiber-forming polymer, an elastomer and an antioxidant as a foam material. The foaming material is subjected to a primary melt blending process and a hot stretching process first, then subjected to a secondary melt blending process and cooling granulation and subjected to a pressing process, and a composite board is obtained. The composite board is subjected to supercritical fluid foaming process, and a composite heat insulation foam material is obtained.

Abstract: The disclosure relates to the technical field of new foaming materials, in particular to a preparation method of a microporous foam material with oriented cells, which comprises the following steps: (1) melting and mixing raw materials for preparing a polymer composite material, and then carrying out hot stretching to obtain polymer composite fibers; the raw materials comprise a polymer matrix, a fiber-forming phase substance and a processing aid; (2) arranging the polymer composite fibers prepared in the step (1) in the same direction, and performing hot pressing to obtain a polymer composite board with oriented fibers; and (3) carrying out supercritical fluid foaming on the polymer composite board prepared in the step (2) to obtain the microporous foam material with oriented cells.

Abstract: Enterprise cybersecurity systems and methods related to receiving or accessing a real-time cybersecurity request, automatically transmitting a live mode request to a first cybersecurity microservice to generate cybersecurity risk-scoring information, receiving a response to the live mode request, calculating a cybersecurity score, automatically populating cybersecurity response data based on the calculated cybersecurity score, and automatically transmitting the cybersecurity response data to the enterprise client electronic device. The enterprise cybersecurity system and method also includes, after the cybersecurity response data has been transmitted to the enterprise client electronic device, automatically transmitting a test mode request to at least one test mode cybersecurity microservice, wherein the test mode request includes real-time data extracted from the real-time cybersecurity request.

Abstract: Described herein are a polyisocyanurate foam, its use in a sandwich panel, a sandwich panel including the foam, and a process for preparing the sandwich panel. The polyisocyanurate foam shows a good adhesion property even without adhesion promoter, improved processability of PIR systems at lower temperature (?50° C.), and an improved flame resistance property.
