Use of nano zinc oxide in chloroprene rubber 5. Hardness, compression set, heat build-up and swelling resistance are found to be comparable for vulcanizates with 2phr ZnO(p), 2phr ZnO(s) and 5phr ZnO(c). 6. Abrasion, flex and thermal ageing resistances are found to be superior for vulcanizates with 2phr ZnO(p) and 2phr ZnO(s) compared to vulcanizate with 5phr ZnO(c). 7. Crosslink density of vulcanizates with 2phr ZnO(p) and 2phr ZnO(s) are slightly higher than vulcanizate with 5phr conventional ZnO. 102
