DEGRADABLE BEARING PALLET AND PREPARATION METHOD THEREOF
A degradable bearing pallet and a preparation method thereof. The pallet has an upper cover, a packing middle layer and a lower cover; a plurality of pallet support legs are disposed at the bottom of the lower cover; the lower cover is integrally molded with the plurality of pallet support legs; and the packing middle layer is filled in the lower cover and in the plurality of pallet support legs; the upper cover covers the packing middle layer and the lower cover. The middle part of the bottom of each of the pallet support legs is formed with a sunken groove; the pallet support legs in each of the rows are mutually connected through a connecting board; and each of the connecting boards is clamped in a corresponding one of the sunken grooves.
POLYOL BLENDS THAT INCLUDE AN ISOPROPYLIDENEDIPHENOL-BASED POLYETHER POLYOL, RELATED COMPOSITIONS AND FOAMS
Polyol blends, isocyanate-reactive compositions, polyurethane foam-forming compositions, methods of producing polyurethane foams, polyurethane foams produced from such compositions and made by such methods. The polyol blends, isocyanate-reactive compositions and polyurethane foam-forming compositions include an isopropylidenediphenol-based polyether polyol in combination with another polyol.
PROCESS FOR PRODUCING POROUS MATERIALS
The present invention relates to a process for preparing a porous material, at least comprising the steps of providing a mixture (I) comprising a composition (A) comprising components suitable to form an organic gel and a solvent (B), reacting the components in the composition (A) in the presence of the solvent (B) to form a gel, and drying of the gel obtained in step b), wherein the composition (A) comprises at least one monool (am). The invention further relates to the porous materials which can be obtained in this way and the use of the porous materials as thermal insulation material and in vacuum insulation panels, in particular in interior or exterior thermal insulation systems.
REFRACTORY ARTICLE AND PRODUCTION METHOD THEREOF
The present invention provides a refractory article which is fire resistant, heat resistant, and light weight, and which is suitable for use as a building material. The refractory article comprises (1) a core material and (2) a refractory layer which covers one or more surface of the core material, and comprises a polyisocyanurate resin. The core material (1) may be a glued laminated timber. Suitable polyisocyanurate resins may be obtained by reaction of a polyisocyanate in the presence of a polyol. A flame retardant may be present in the polyisocyanurate resin.
Expanded foam solution and thermosetting expanded foam having excellent flame retardancy using the same
The present disclosure relates to an expanded foam solution for forming a thermosetting expanded foam having excellent flame retardancy produced using the same. According to the present disclosure, nanoclay is mixed with a polyol-based compound using ultrasonic waves, an isocyanate-based compound is added, and a trimerization catalyst or an isocyanurate compound is mixed with the polyol-based compound so that an isocyanurate structure is formed.
FORMULATED ISOCYANATE-REACTIVE BLENDS INCLUDING OLEFIN BASED BLOWING AGENT
A storage stable isocyanate-reactive composition has ethylene oxide content from 1 wt % to 50 wt %, based on the total weight of an isocyanate-reactive component that includes a polyol component, a catalyst component, and a blowing agent component. The polyol component includes at least one polyol, the catalyst component includes at least one amine catalyst, and the blowing agent component includes at least one hydrohaloolefin based blowing agent. The isocyanate-reactive component is storable at least at one of room temperature and a higher temperature for a period of at least 1 day with a less than 10 second change in gel time when reacted with an isocyanate component at an isocyanate index from 100 to 150, compared to when the same isocyanate-reactive component is stored for a period of less than 1 day at room temperature and reacted with the same isocyanate component at the same isocyanate index from 100 to 150.
