NBR-PVC Blend NPR SS SCCARE NPR SS is a unique blend of Nitrile Rubber and Polyvinyl Chloride with a very high percentage of Plasticizers, etc., Test reports have proved that SCCARE NPR SS has extremely good processing qualities. It has a unique law hardness quality with extremely good physical properties. Handling, cutting and weighing of SCCARE NPR SS is easy as it comes in soft sheets, thus saving on time, cost and labour.
Processing Characteristics: SCCARE SSR can be easily processed on conventional Rubber mixing/compounding machines. It has excellent filler and plasticizer absorption properties and can withstand elevated, compounding temperatures. Typical Properties of Raw Polymer:

Curing: Sulphur or peroxide curing is recommended. SCCARE NPR SS has improved curing properties as compared to other similar polymers. A slightly higher dosage of accelerators is recommended. Applications: Since SCCARE NPR SS has a very law polymer hardness not found in NBR/PVC blends it has unit advantage to manufacture law hardness printing rollers, molded articles, law density foam, soft pipes, tubes and hoses. Packaging: 25kgs Laminated HDPE Bags
