NBR reclaimed rubber and SBR rubber used to improve cold resistance

NBR renewable rubber excellent oil resistance, wear resistance, widely used in the production of a variety of oil, wear-resistant rubber products. The use of nitrile rubber reclaimed rubber production of different types, different uses of rubber products, the application of reclaimed nitrile rubber is different: low-grade oil-resistant rubber products can be fully used nitrile rubber reclaimed production, nitrile rubber reclamation can also be used with other reclaimed rubber, Natural rubber, synthetic rubber and use; which reclaimed nitrile rubber and styrene butadiene rubber and the use of rubber products can greatly improve the performance of cold hardiness.

Nitrile rubber reclaimed from waste nitrile rubber products as raw material processing, and nitrile rubber has the same excellent oil resistance, good wear resistance and a certain degree of heat resistance, but the performance of low temperature reclaimed rubber NBR, propylene The more nitrile content, the better the oil resistance of the nitrile rubber reclaim low temperature, the poorer the cold resistance.

SBR physical mechanism performance, processing performance and product performance close to the natural rubber, wear-resistant, heat-resistant, anti-aging and curing speed better, and the regeneration of the good compatibility of nitrile, and in theory can be Butyronitrile rubber regeneration and use; but SBR rubber oil-filled butadiene rubber and nitrile rubber regeneration with poor results, so the general reclaimed rubber formulations do not add oil-filled styrene-butadiene rubber), styrene-butadiene rubber excellent cold resistance, Low temperature flexibility is good, added to the reclaimed rubber products formulations and its use can be used just to improve its poor cold shortcomings.

The use of nitrile rubber reclaimed with styrene-butadiene rubber and rubber products, in addition to not be able to choose oil-extended styrene-butadiene rubber, you should also pay attention to the following questions: When the nitrile rubber and styrene-butadiene rubber reclaimed rubber, nitrile rubber reclaim should choose propylene The low acrylonitrile product with nitrile content below 35% can not improve the oil resistance of the reclaimed acrylonitrile butadiene rubber even if it is a high acrylonitrile butadiene rubber, which will help to reduce the cost. When SBR rubber is used with styrene butadiene rubber, The amount of rubber should be 40% or less.

The combination of nitrile rubber and styrene butadiene rubber and the use of rubber products can not only ensure excellent oil resistance of rubber products, but also improve the cold resistance of recycled rubber products, improve the comprehensive performance of rubber products and extend the service life of rubber products, which are commonly used by rubber products manufacturers A mode of production.

Hebei Hongyun renewable plastic factory production of nitrile rubber reclaimed rubber oil resistance large, feel good elasticity, smooth appearance of the product appearance, plasticity, abrasion, acid, anti-aging, can be used alone instead of Russia 26 Nitrile rubber seal production, pipeline Road, oil pads, oil seals and other products.
