AN ADHESIVE COMPOSITION AND USE THEREOF FOR BONDING OF PLASTIC FOAM PLATES
A hot-melt adhesive composition, which can be used for bonding of expanded polystyrene foam plates and expanded extruded polystyrene foam plates. The adhesive composition includes at least one at 25° C. solid poly-α-olefin, at least one tackifying resin, and at least one organic phosphorus-containing compound. The invention also uses adhesive composition for bonding of plastic foam plates, to a method for producing a composite element, and to a composite element including a first and second substrate bonded to each via a layer of adhesive composition of the present invention.
SURFACE MODIFICATION OF POLYMER FOAMS USING PLASMA
An embodiment includes a system comprising: a monolithic shape memory polymer (SMP) foam having first and second states; wherein the SMP foam includes: (a) polyurethane, (b) an inner half portion having inner reticulated cells defined by inner struts, (c) an outer half portion, having outer reticulated cells defined by outer struts, surrounding the inner portion in a plane that provides a cross-section of the SMP foam, (d) hydroxyl groups chemically bound to outer surfaces of both the inner and outer struts. Other embodiments are discussed herein.

A barrier coating is formed on at least one of the first major surface and the second major surface, the barrier coating being formed from a barrier coating composition comprising a dispersion of at least one polymer comprising at least one polymer selected from polyvinylidene dichloride (PVDC), polyvinylidene fluoride (PVDF), polyvinyl chloride (PVC), polyvinyl alcohol, ethylene vinyl alcohol, polyurethane, styrene butadiene (SBR), and combinations or copolymers thereof; and a viscosity modifier.
Fibre reinforcement of reactive foams obtained by a moulding foam method
The present invention relates to a molding made of reactive foam, wherein at least one fiber (F) is arranged partially inside the molding, i.e. is surrounded by the reactive foam. The two ends of the respective fiber (F) not surrounded by the reactive foam thus each project from one side of the corresponding molding. The reactive foam is produced by a mold foaming process. The present invention further provides a panel comprising at least one such molding and at least one further layer (S1). The present invention further provides processes for producing the moldings according to the invention from reactive foam/the panels according to the invention and also provides for the use thereof as a rotor blade in wind turbines for example.

High-temperature foams with reduced resin absorption for producing sandwich materials
High-temperature foams are produced and used in the construction of aeroplanes, ships and rail and other vehicles. In particular, the foams are further processed into sandwich materials by joining with two outer layers. To this end, a novel process is used for producing high-temperature foams (HT foams) which are particularly suitable for producing such sandwich components for lightweight construction. This process achieves an improvement in the processability of the HT foams produced and a weight reduction of the sandwich materials. The HT foams are furthermore rigid particle foams which are markedly more economic to produce than rigid block foams. In particular, a reduction is brought about in resin absorption in fibre composite processes through a process-related optimization of the surface constitution.
