Various embodiments relate to plastic-metal junctions and methods of making the same via laser-assisted joining. The present invention provides a method of forming a junction between a metal form and a solid plastic. The method can include laser treating a surface of a metal form to generate a feature (e.g., a plurality of at least one of pores and grooves) in the surface of the metal, wherein the laser has an angle of incidence with the surface of the metal of other than 0 degrees. The method can include contacting the metal surface including the feature with a flowable resin composition. The method can include curing the flowable resin composition to form the solid plastic, to provide the junction between the metal form and the solid plastic.

The invention relates to a method to reduce or prevent agglomeration of polyisobutylene particles in aqueous media by LCST compounds and highly pure isobutylenes obtained thereby. The invention further relates to polyisobutylene products comprising the same or derived therefrom.

A physically crosslinked, closed cell continuous multilayer foam structure comprising at least one polypropylene/polyethylene coextruded foam layer is obtained. The multilayer foam structure is obtained by coextruding a multilayer structure comprising at least one foam composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.

A composite article comprises an article presenting a surface and a thermally expandable composition disposed on the surface of the article. The thermally expandable composition comprises (a) from about 35 to about 65 percent by weight of a polyolefin resin; (b) from about 2 to about 15 percent by weight of a thermoplastic resin; (c) from about 1 to about 6 percent by weight of a curing agent suitable for cross-linking the polyolefin resin (a); (d) from about 15 to about 45 percent by weight of filler; and (e) from about 1 to about 10 percent by weight of a chemical blowing agent which is activated at an activation temperature, each based on the total weight of the thermally expandable composition. Methods of preparing and using the composite article, and an assembly formed from the composite article, are also disclosed.

An electrofusion coupling member made of a thermoplastic substance having aluminum particles incorporated therein and further comprising an electric resistance heating element disposed therein, an electrofusion coupler device which includes the same, and a method for welding the device to other thermoplastic objects are provided herein.

Herein are disclosed apparatus and methods for impinging fluids, e.g. heated fluids, onto the surface of substrates and then locally removing the impinged fluid. The apparatus may comprise at least first and second fluid delivery outlets that are in diverging relation to each other. The apparatus may comprise at least first and second fluid capture inlets that are locally positioned relative to the first and second fluid delivery outlets, respectively. The apparatus and method may be used e.g. to impinge fluids onto two converging substrates and may be used to heat the surfaces of the substrates so as to facilitate melt-bonding the substrates to each other.

A composite housing and a method of assembling a composite housing for a scanning assembly. A body of the housing defines an opening of a first perimeter. A polymethylpentene scanning plate is provided which has lip with a marginally larger perimeter than the first perimeter. During assembly of the composite housing, at least a part of scanning plate is thermally contracted to allow it to be positioned within the opening such that the peripheral side surface of the scanning surface faces the edge of the body. When the scanning plate returns to ambient temperature and expands at least a portion of the side surface of the scanning plate engages the edge of the body.
