  • Process for producing glove having interpenetrating network structure
    Publication number: 20060052501
    Abstract: A process for producing an elastomeric article having an interpenetrating network structure included the following steps. Firstly, a mold is contacted with an elastomeric composition. The elastomeric composition includes a base latex and a thermoplastic ethylene-vinylacetate (EVA) copolymer latex. The base latex includes a styrene-butadiene rubber (SBR) latex and a carboxylated styrene-butadiene rubber (C-SBR) latex, and the mixing ratio of the base latex to the EVA copolymer latex is from 95:5 to 40:60. Then, the elastomeric composition on the mold is allowed to perform a vulcanization reaction, thereby forming the elastomeric article having the interpenetrating network structure.

  • Elastomeric composition and process for producing glove having interpenetrating network structure
    Patent number: 7001941
    Abstract: An elastomeric composition includes a base latex and a thermoplastic ethylene-vinylacetate (EVA) copolymer latex. The base latex includes one or at least one of a styrene-butadiene rubber (SBR) latex and a carboxylated styrene-butadiene rubber (C-SBR) latex. A process for producing an elastomeric article having an interpenetrating network structure included the following steps. Firstly, a mold is contacted with such elastomeric composition. Then, the elastomeric composition on the mold is allowed to perform a vulcanization reaction, thereby forming the elastomeric article having the interpenetrating network structure.
