Extruded tape

Variety of form. Rubber base adhesives can be supplied for assembly operations as solvent or water-borne dispersions, hot melts, precast films, extruded tapes or reinforced films. In addition solvent and water-borne dispersions can be supplied as single or two-components systems. 

Other self-reinforced polymers are being developed. For example, PURE is based on highly oriented co-extruded tapes of polypropylene and a consolidation binder. Properties vary according to the form (see Table 6.27) - sheets, tapes or fabrics.

Co-extrusion is another technique to produce SPCs. The outer layer of the co-extruded and drawn tapes has a lower melting temperature than the core. The desired objects are prepared from various assemblies of the co-extruded tapes (woven, laminates of different lay-ups) by hot pressing methods. The majority of the research has focused on a combination of a PP homopolymer for the core of the tape, and PP copolymer as the skin. After...

Extruded Tapes. These are preformed ribbons or profiles of butyl rubber, neoprene, or polyvinyl chloride, and may be either solid or expanded. They may be supplied as composite structures with rubber cores, rubber rod spacer, or aluminum shims surrounded or embedded in an adhesive or sealant. 

As supplied in a cartridge, in bulk or as extruded tapes, sealants and caulks are of nine types, described below.

The aim of the present woik was preparation of microfibrillar-phase morphology in the PP/PE blends with polypropylene as a minority component. For these purposes an extrasion line based on conventional singlescrew extrader and semihyperbolic-converging die was employed. It was proved that the formation of fibrillar structure in one processing step can be achieved using blends with various content of polypropylene (the blends with 20, 30 and 40 wt.% of PP were studied) and both compounded and hand-mixed materials (twin-screw extruder compounded and non-compounded materials were processed). Since the structure and properties of polymer parts are mutually interconnected, the extruded tapes with microfibrillar morphology were examined by several methods of structure analysis and measurements of properties. The results can be summarized as follows ...
