Powder Nitrile rubber modified PVC(PNBR)

The modified PVC powder Nitrile Butadiene Rubber is improver and modifier researched and developed for PVC polymer materials. It has a good compatibility with the PVC polymer materials. On the one hand, NBR can improve product flexibility, abrasion resistance and tensile strength. On the other hand, enhance oil resistance, aging tolerance, cold resistance and other properties. Thus increase product strength and extend the service life.

Main brands

Products with medium temperature polymerization, self isolation and condensed into powder process of low Mooney viscosity, semi(micro) crosslinking.The powdered Nitrile Butadiene Rubber is combination of medium and low nitrile content. There are two brands for clients choices according to formula needs.

Application advantages

1. The use of powdered Nitrile Butadiene Rubber in modified PVC can well improve product properties of oil resistance and solvent resistance.

2. Play a special role in improving PVC no flexibility, no elasticity chain structure and bad low-temperature performance.

3. Powdered Nitrile Butadiene Rubber used with PVC can improve its stability, relaxing the restriction on processing operation.

4. Powdered Nitrile Butadiene Rubber can well improve antiskid performance of PVC.

5. Used with PVC can improve product resistance performance.

6. Powdered Nitrile Butadiene Rubber can well improve abrasion resistance of PVC, thus prolong the service life to great extend.

7. The use of powdered Nitrile Butadiene Rubber in modified PVC can prevent the migration of plasticizer, thereby increase product viscosity un der the condition of high temperature.

8. Powdered Nitrile Butadiene Rubber has excellent compatibility with PVC, can use calendering, extruding and other production process.
