INTRODUCTION

NBR NBR3305
A brief description:
     Lanzhou Petrochemical Company from Japan Zeon Corporation has introduced a full set of the world's advanced nitrile rubber production plant with annual production capacity of 15,000 tons. The production of nitrile rubber device N32 is a high cold polymerization of acrylonitrile with the acrylonitrile content - butadiene rubber, the Mooney viscosity is low, processing and better performance. It has good mill and mixer mixing performance, rolling performance and basic performance, but at a high temperature also has good oil resistance, fire performance. N32 has good water resistance, workability, low shrinkage, low shrinkage and good mixing of the physical and mechanical properties, making it widely used in the oil products.
