摘要:
Crosslinkable ethylene-vinyl acetate copolymer resins are rendered amenable to forming adherent laminates with crosslinkable silicone rubber by coating the surface of the ethylene-vinyl acetate resin with a solution of a silane or a member of the class of compounds known as polyfunctional monomers prior to adhering the resin to the silicone rubber.
摘要:
Crosslinkable ethylene-vinyl acetate copolymer resins are rendered amenable to forming adherent laminates with cross-linkable silicone rubber by admixing the ethylene-vinyl acetate resin with certain selected silanes prior to adhering the resin to the silicone rubber.
摘要:
Crosslinkable ethylene-vinyl acetate copolymer resins are rendered amenable to forming adherent laminates with cross-linkable silicone rubber by dusting the surface of either the resin or rubber, or both, with a bonding agent.
摘要:
A filled crosslinked polymeric composition of ethylene-vinyl ester copolymer which has a significant degree of flame retardancy by inclusion of a dual lubricant system which includes a fatty acid and an alkylene-bis-amide.
摘要:
The present invention relates to improved polymeric compositions based on ethylene-vinyl ester and ethylene-alkyl acrylate copolymers which can be crosslinked to provide insulation coatings for wire and cable products. The copolymer compositions contain a hydrated inorganic filler, an alkoxysilane, an antioxidant and a polymeric processing additive. Organic peroxides are preferably employed to facilitate crosslinking. An improved method for providing the improved compositions and electrical conductors coated with the crosslinkable polymeric compositions are also provided by the invention.

The invention relates to improved flame retardant crosslinkable compositions useful as insulation coatings for wire and cable based on ethylene-vinyl ester and ethylene-alkyl acrylate copolymers. The compositions contain a hydrated inorganic filler, an alkoxysilane, an antioxidant and a hydrocarbon processing oil. Organic peroxides are preferably employed to facilitate crosslinking. A method for providing the improved flame retardant crosslinkable compositions and electrical conductors coated therewith are also provided.
摘要:
The present invention relates to improved flame retardant insulation/jacketing compositions for wire and cable products based on ethylene-vinyl ester and ethylene-alkyl acrylate copolymers. The copolymers are formulated with a hydrated inorganic filler, an alkoxysilane, a crosslinking agent, a processing additive and a combination of specific antioxidants, namely, a pentaerythritol betaalkylthiopropionate and a hindered phenol. The formulations stabilized with the pentaerythritol betaalkylthiopropionate/hindered phenol combination have good heat stability and do not tarnish or discolor the surface of the copper conductor upon steam vulcanization.
摘要:
Flame retardant and abrasion resistant crosslinkable compositions useful as insulation for wire and cable are provided. The compositions contain an ethylene-vinyl acetate copolymer having a vinyl ester content of 5 to 12 wt. %, a halogenated compound, antimony trioxide and an organic peroxide. Use of specific halogenated compounds, particularly brominated aromatic compounds, with low vinyl acetate content ethylene-vinyl acetate copolymers yield products which are highly resistant to abrasion after crosslinking.
摘要:
Crosslinkable ethylene-vinyl acetate copolymer compositions containing silane-treated hydrated inorganic filler are capable of passing the CSA varnish test if an antioxidant composition comprising distearyl-3, 3' thiodiproprionate is admixed therewith.
