Product Description

 Blue Star ^TM SN121
Introduction
Chloroprene rubber SN121 is a general purpose, it is obtained by sulfur modified and Chloroprene monomer by emulsion polymerization 
with low rate of crystallization, for using a Nairit recipe and process technology. It can be seen as an equivalent to Dupont GNA of the United States.
Characteristics
l  Good properties of physical mechanics and plastication;
l  Better compatibility in combination with other types;
l  Compared with CR121, SN121 has better processability, more mastication, mixing and extrusion, the surface of sheet is flat and smooth and smaller shrinkage, especially, SN121 is a superior to curing characteristics of compound;
l  The same processability as Dupont GNA of the United States;
l  Good quality in products appearance;
l  Good resistant to oil, chemical reagents, ozone aging, sunlight, extension of the fine is not flammable and better electrical, as well as processing of security and stability.
Appearance
Light yellow or amber chips, with talcum as a release agent, no mechanical impurities, no scorch particles.
