A phenolic foam formed from a composition comprising a phenolic resin, a blowing agent, an acid catalyst, and a surfactant comprising: (i) an ethoxylated castor oil, and (ii) a polysiloxane comprising a side chain comprising polyethylene oxide wherein the total molecular weight of the polyethylene oxide of the side chain comprises less than 50% of the total molecular weight of the polysiloxane.

The present invention relates to the field of products known as solid surface. In particular, the present invention relates to a precursor liquid composition of a solid surface material, the solid composition formed from said liquid composition and their manufacturing processes.

A flexible discontinuous process produces a series of at least two articles containing thermally insulating polyurethane foam from at least three streams (A), (B) and (C). The process involves mixing the at least three streams with different mixing ratios and injecting the mixture into cavities of the articles. A production unit can be used for performing this process.

Aspects of the present disclosure relate to a polyolefin composition and processes suitable for use in forming a lid for a hot food or beverage container that has a stiffness comparable to a similar lid made using high impact polystyrene and a density less than water at 23° C.

The present invention relates to a composition comprising a copper(II)-salt capable of being used as a catalyst, a process for the manufacture of said composition, the use of said composition as a catalyst, in particular, as catalyst for the reaction of at least one isocyanate compound with at least one isocyanate-reactive compound, in particular for the manufacture of polyisocyanate polyaddition products, such as polyurethanes, in particular, polyurethane foams.

A method of producing a closed-cell and rigid foam. The method comprises reacting an isocyanate composition including one or more polyisocyanates and a polyol composition including one or more polyols including one or more aromatic polyester polyols having a hydroxyl functionality of greater than 2 and one or more physical and/or chemical blowing agents including methylal to form a closed-cell and rigid foam configured to retain at least 85% of an initial volume of the closed-cell and rigid foam when exposed to about 97% relative humidity at about 70° C. for at least seven or more days.

A reinforcing sheet including one or more layers of a reinforcing material, and a thermosetting adhesive associated with the reinforcing material, wherein the thermosetting adhesive includes a curing agent, and an epoxy-modified dimerized fatty acid combined with an epoxy terminated polyurethane interpenetrating network.

Various embodiments disclosed relate to pore inducers and porous abrasive forms made using the same. In various embodiments, the present invention provides a method of forming a porous abrasive form including heating an abrasive composition including pore inducers to form the porous abrasive form. During the heating the pore inducers in the porous abrasive form reduce in volume to form induced pores in the porous abrasive form.

Polymer foams based on polyetherimides (PEIs) fulfill the legal specifications demanded by the aviation industry for aircraft interiors. Specifically, the demands on fire characteristics, stability to media and mechanical properties constitute a great challenge here. According to related art, suitable polymer foams are produced as semi-finished products. Reprocessing to give shaped articles is uneconomic in terms of time and material exploitation, for example by virtue of large amounts of cutting waste. The material is suitable in principle and can be processed to give particle foam mouldings. These mouldings can be produced without reprocessing in short cycle times and, hence, economically. Furthermore, this gives rise to new means of functional integration, for example by direct incorporation of inserts etc. in the foam, and with regard to freedom in terms of design.

A cleaning implement for cleaning a target surface is provided that includes an erodible foam adapted to contact a surface to be cleaned and a rheological solid composition comprising a crystallizing agent and an aqueous phase.
