Tape foamed

Table 2 indicates that only the acrylic foam tapes comjjete in adhesive strength comparison in any realistic sense with the conventional adhesives. 

An example of the contribution of polar interactions between an acrylic PSA and a substrate is shown in Fig. 6. By copolymerizing iso-octylacrylate and acrylic acid, using a monomer ratio of, respectively, 95/5 and 90/10, two otherwise identical PSAs were made. The PSAs were laminated to both sides of a foam core to make an attachment tape as used in the automotive industry for the application of body side moldings to a car. One side of the foam tape was laminated against an aluminum foil backing. The other side was laminated against an automotive paint-coated panel to make the final test sample. The test sample was allowed to... 

If outdoor air can easily leak into and through homes, both comfort and energy-efficient performance will be difficult to maintain. Today, off-the-shelf technologies that contribute to airtight construction include a variety of house wraps, sealants, foams, and tapes. In energy-efficient homes, builders use these tools to seal the myriad of cracks... 

Duct mastic has replaced duct tape as the most effective sealing material. Mastic is a fibrous, elastomeric compound that permanently seals duct connections and seams. In addition, the boot connections between ducts and floors and between walls and ceilings should be fully caulked and/or foamed airtight. Lastly, air handlers that house the... 

In the special case of pipelines operating at relatively high temperatures such as for the transmission of heavy fuel oil at up to 85°C, heat insulation and electrical insulation are provided by up to 50 mm of foam-expanded polyurethane. As a further insurance against penetration of water, and to prevent mechanical damage, outer coatings of polyethylene (5 mm), butyl laminate tape (0-8 mm) or coal-tar enamel reinforced with glass fibre (2-5 mm) have been used. 

Quadraxially oriented (four directional layer) glass fabric-TS vinyl ester polyester RP sheet panels with a foam core and gel coating are used. Most of the panels are 3 mm thick with molded-in rib structure supports. Body skins are bonded to the chassis with a double-stick acrylic tape developed by 3M Co. as well as mechanical fasteners. Unlike most steel designs, no B-pillar structural component between the front and rear doors is required thus providing more interior space and easy entry since doors open in opposite directions. 

Over the last few decades, the use of radiation sources for industrial applications has been widespread. The areas of radiation applications are as follows (i) Wires and cables (ii) heat shrinkable tubes and films (iii) polymeric foam (iv) coating on wooden panels (v) coating on thin film-video/audio tapes (vi) printing and lithography (vii) degradation of polymers (viii) irradiation of diamonds (ix) vulcanization of mbber and rubber latex (x) grain irradiation. 

Neoprene. An elastomer with the repeating structure, -C4H7CI-, that comes in the form of solid, latex, and flexible foam. Used as coatings, sealants, protective garments, adhesive tapes, etc.

This certificate relates to Climatube extruded foam PE pipe insulation. It is used in the thermal insulation of water supply pipes and heating pipework. The insulation is semisplit for ease of fitting, and polychloroprene adhesive and climatape adhesive tape are supplied for sealing cut ends and joints. Thermal conductivity data are tabulated.

A furniture company is using sheets of PP foam, supplied by Ametek Microfoam, to protect upholstered furniture in transit. The sheeting is taped into pouches and used to surround the furniture before it is packed into corrugated cases. The company has reduced its corrugated use by 60%. 

Examples are given of the use of extruded PE foam sections in conjunction with other polymeric materials in the production of triangular, semicircular, rectangular and trapezoidal profiles, e.g. beam-like structures in which the rigid support may be of GRP. The foam can be bonded with thermally-fusible adhesives or two-sided self adhesive tape affixed to the foam prior to fabricating. A standard range of the foam prodncts is available, but other types can be tailor-made. 

Different horticultural items made of biodegradable polymers, such as plant pots, seed/fertilizer tape and binding materials, foams and nets for erosion control, offer reduction of system complexity by reducing the number of work steps. 

Common uses for polyester resins are reinforced plastics automotive parts boat hulls foams encapsulation of electrical equipment protective coatings ducts flues and other structural applications low pressure laminates magnetic tapes piping bottles non-woven disposable filters and low-temperature mortars.
