“…8 Chloroprene (CR) finds special application in many products such as gaskets, cable jackets, tubing, automobile parts, seals, O-rings, tyre-sidewalls, gasoline hoses, textile, weather-resistant materials, 9 adhesives and electrical insulations and coatings. 10 The effective use of carboxy-terminated liquid natural rubber (CTNR) as a polymeric plasticizer in CR vulcanizates was previously reported. 11 This work illustrates the use of commercial nano silica as an effectual filler in CR vulcanizates containing CTNR as a polymeric plasticizer.…”
