Synthetic polyisoprene latex condoms with reduced nitrosamine |
| abstract |
A synthetic polyisoprene latex emulsion has pre-vulcanization composition and post nvulcanization composition. The pre-vulcanization composition comprises insoluble namorphous sulfur extracted with zinc dithiocarbamate catalyst at 20°C to form sulfur chain nand transported to interior of synthetic polyisoprene particle forming physical attachment of nsulfur to active sites. The degree of pre-vulcanization is verified by expansion of cast and ndried film of latex in toluene in 20 minutes by means of a swelling index test. The latex nemulsion is vulcanized at 90°C to 120°C for 3 to 5 minutes. Post-vulcanization composition nwith accelerators crosslink between synthetic polyisoprene particles, uniformly curing both in nthe inter-particle and intra-particle regions to produce high cross link density, uniform ndistribution of double bonds with zinc segregation at the boundaries of original particles. The ncondom exhibits high tensile strength, tensile modulus, elongation with excellent tear nstrength releasing below 10 ppb of nitrosamines.n1/1 nProcess Overview Chemicals and additives nL Natural raw 1 latex .... . nCompounin Attrition11:1 nDipping (Validaion)1)Dipping(ank1) n2) Dipping drying # 1 n3) Dipping (tank 2) n4) latermediale drying 2 n5) Pre-beading nWashing&Drying 6) Vulcanizing n7) Leaching nEletoF testiG UREilingP nFIGURE 1 |
