Basic Character

HLN 35-3 is high temperature polymerized, slight crosslinked arylontrile butadiene rubber which has low mooney viscosity and middle ACN content. It uses special technology of agglomeration into powder. It shows good resistance to oil, heat, cold and solvent. It also has good compression resistance, ageing resistance and convenient machining property.

Property Superiority

HLN35-3 is good PVC resin modifier agent. It has very good compatibility with PVC resin. They can mix together in certain percentage.

HLN 35-3 can reach the machinery performance requirement of abroad similar products. It’s specially adapted in PVC resin modification and soft goods.

Application   

HLN 35-3 is mainly used in shoes, oil pipe, general gland strip, conveyer belt and so on.

Application Guidence   

According to different usage and different demand, the dosage of HLN 35-3 is viriable. When HLN35-3 mix with PVC resin, and the PVC needs to be plasticated, the plastication temperature should be lower than 40℃, then add the powdered NBR HLN 35-3 and blend evenly. In the process of extrusion, we advice the process temperture be 120-170℃; In the process of calendering, we advice the process temperture be 150-170℃; In the process of injection, we advice the process temperture be 170-190℃.

Safe guidence    

Except for good industrial operation diretions, there is no special safe measure demanded. Please prevent dust formation and keep away from fire.
