Nitrile reclaimed rubber is a new type of rubber processed from waste nitrile rubber products after many special processes such as desulfurization. It retains most of the molecular structure and performance characteristics of nitrile rubber, especially excellent oil resistance, and is widely used In the production of various kinds of oil-resistant rubber products, not only can reduce the cost of raw materials, but also can improve the process of nitrile rubber products and product performance.
1, nitrile rubber reclaimed rubber can reduce the cost of raw materials of rubber: including reclaimed rubber, including all reclaimed rubber products in rubber products, the biggest effect is to reduce raw material costs. The raw material of nitrile reclaimed rubber is waste rubber products, the price of which is much lower than the price of nitrile rubber, which is about half of the price of nitrile rubber. Substitution of nitrile rubber can significantly reduce the cost of raw materials.
2, nitrile rubber reclaim can improve the processing performance of oil-resistant rubber products: NBR reclaimed rubber in the production process through the full mastication, with good plasticity and mobility, easy processing, added to the nitrile rubber to improve the oil-resistant rubber products The processing technology, saving labor.
3, NBR reclaimed rubber affect the performance of oil-resistant rubber products: oil-resistant rubber products with appropriate amount of NBR reclaimed rubber, rubber content of rubber, permanent deformation, hardness and other indicators have decreased elongation at break Rise, anti-aging properties of oil-resistant rubber products significantly improved; nitrile rubber reclaimed rubber products in the oil there is a certain degree of softening effect.
In nitrile oil rubber products, add the right amount of nitrile rubber reclaim reduce costs, we must promptly adjust the rubber products formula: For example, increase the amount of oil-resistant rubber products in high wear-resistant carbon black to improve the tensile strength of oil-resistant rubber products, tear Strength, aging resistance and wear resistance; reduce the amount of plasticizer such as dibutyl ester in oil-resistant rubber products; adjust the vulcanization system, anti-aging system and filling system according to the performance requirements and production efficiency of rubber products.
Reasonable and correct use of nitrile rubber reclaim can not only ensure the quality and service life of oil-resistant rubber products, but also significantly reduce the cost of raw materials, making it an ideal choice for oil resistant rubber products manufacturers. However, the quality of nitrile reclaimed rubber products on the market is uneven, and the majority of rubber product manufacturers need to polish their eyes and choose the most suitable nitrile rubber reclaimed rubber products.
