"NBR rubber" and "oil" has always been the word, we can see nitrile rubber reclaimed rubber excellent performance is deeply rooted, was used in a variety of oil-resistant rubber products. Nitrile reclaimed rubber retains the advantages of nitrile rubber, but also some of the same disadvantages with the same nitrile rubber, nitrile rubber reclaimed the advantages and disadvantages to improve the use of reclaimed rubber significance.
Nitrile rubber is an interpolymer of butadiene and acrylonitrile. It contains polar AN groups and has high stability to non-polar or weakly polar animal oils such as vegetable oils and liquid fuels. Therefore, the oil resistance Excellent; at the same time nitrile rubber oil, abrasion, oil resistance, air tightness, strong adhesion; butyronitrile reclaimed rubber to waste nitrile rubber, waste nitrile rubber products as raw material processing and therefore have a small Advantages of nitrile rubber.
Nitrile rubber reclaimed as nitrile rubber, nitrile rubber products re-processed products, while retaining the advantages of nitrile rubber, but also the same shortcomings and nitrile rubber, that is cold, ozone resistance, poor insulation , In the course of the need to add reinforcing carbon black reinforcement, and through a reasonable formula to improve the shortcomings of nitrile rubber reclaimed.
The use of nitrile rubber reclaimed rubber production, we can rely on its advantages to produce some oil-resistant hose, oil-resistant rubber shoes, oil-resistant rubber and other high-oil rubber products, or rubber friction blocks such as high wear-resistant rubber products, or Some heat-resistant rubber products.
NBR renewable rubber cold resistance, ozone resistance, poor insulation, is not to reduce the value of a lot of use, such as can not be used to produce hardy rubber products. In fact, this sentence is not right, that is not comprehensive. In actual production, nitrile reclaimed rubber is still able to produce some good oil resistance of cold-resistant hose, this time you need to select a lower acrylonitrile nitrile reclaimed rubber, because of the cold resistance of reclaimed rubber with acrylonitrile Content increase and decrease; or added to some conductive, semi-conductive rubber products, and it is the use of nitrile rubber reclaimed less insulating, low resistivity defects, by adding an appropriate amount of acetylene black achieve.
Thus, as long as the use of reasonable, nitrile rubber reclaim the advantages and disadvantages can be used to play its greatest value.
