| Product Description: Akrosperse ZnO/CN-80/NBR is a polymeric dispersion of specially-treated zinc oxide. This is a high purity ZnO designed to improve scorch time in carboxylated nitriles. It can replace zinc peroxide dispersions at a much lower cost (use part-for-part on an active material basis). Typical dosage is 6.25 phr (5 phr ZnO/CN). Most zinc peroxide dispersions require 10 phr to get equal activity. As the accompanying data shows, an equal activity loading of ZnO/CN-80 gives a higher state-of-cure than ZP-1014 (zinc peroxide) which translates into higher modulus, improved abrasion resistance and lower compression set. Advantages: Polymer bound or encapsulated dispersions are a proven means of upgrading plant safety, efficiency, quality & raw material control. Akrochem polymer bound or encapsulated chemical dispersions eliminate any irritating dust, as well as other potential hazards in handling powders in the plant. The physical form is easy to handle and weigh accurately. With a dispersion, better uniformity of the mix at lower processing temperatures is possible. Information provided by Akrochem Corporation |
