HLN35-4
1. Product Character
HLN35 series of powdered NBR are resin modifier which are specially for high molecular material such as PVC modification, they have good compatibility with PVC resin. They can highly improve the oil resistance, cold resistance and aging resistance performance in PVC products. They show high decentrality, easy operability, particles refining and other advantages.
35-4 is uncross link PNBR(linear structure), which can soluble in Ketone, Toluene, Dimethylbenzene, and other common solvents, specifically recommended for semihumid and humid (solvent type) processing.

3. Application Advantages
3.1 Oil and solvent resistance
PNBR contains much-CN group, it can improve oil and solvent resistance for PVC.
3.2 Cold resistance
Due to PVC molecule’s no flexible and elastic chain structure, so it shows bad low temperature resistance. Adding PNBR elastomer, and its low temperature resistance performance can be improved.
3.3 Excellent insulativity
When only use PVC, its insulativity is not good. Adding PNBR, it can improve the products’ electrical resistivity.
