Beschreibung
Zusammenfassung:	A non-halogenated heat-recoverable article which passes the UL Standard for Safety for Extruded Insulating Tubing, UL 224, Fifth Edition, VW-1 flame test is prepared from a composition which contains polyethylene or an ethylene copolymer or a mixture, a hydrated or carbonated inorganic filler, red amorphous phosphorus, and an inorganic filler such as zinc borate. The article has good physical properties as measured by tensile strength and elongation, and good high temperature performance. A particularly useful article is heat-recoverable tubing which has good flame-retardancy as demonstrated by the VW-1 test.
