Nitrile rubber is the main raw material for producing oil-resistant rubber products, and oil-resistant rubber sheet is one of them. However, the price of nitrile rubber is quite high, and the production cost of oil-resistant rubber sheets made of nitrile rubber is too high. This will not only bring serious cost pressures to manufacturers, but also weaken product market competitiveness. Therefore, nitrile rubber is oil-resistant Rubber sheet manufacturers usually choose to add a certain proportion of low-cost raw materials to the formula to reduce production costs and improve economic benefits while meeting the standards for oil-resistant rubber sheets.
1. Low-priced filler
Using low-cost fillers to increase the volume of rubber products is a traditional way to reduce the production cost of rubber products. When using nitrile rubber to produce oil-resistant rubber sheets, calcium carbonate is the most commonly used low-cost filler. The rubber sheet manufacturer can decide whether to use light calcium filling or heavy calcium filling according to actual needs, or use light calcium and heavy calcium together in a certain ratio . It should be noted that too much calcium carbonate will cause problems such as reduced mechanical strength of the nitrile rubber sheet and whitening of the black rubber sheet.
2. Nitrile reclaimed rubber
Reclaimed rubber is the third largest category of rubber after natural rubber and synthetic rubber. Its role in the rubber products industry is to replace high-priced raw rubber and reduce the cost of raw materials for rubber products. The nitrile reclaimed rubber processed from waste nitrile rubber or waste nitrile rubber products as raw materials retains the excellent oil resistance and abrasion resistance of nitrile rubber, and can directly replace all or part of the original nitrile rubber to produce oil-resistant rubber sheets. Reduce raw material costs. Among them, the proportion of nitrile reclaimed rubber used in the oil-resistant rubber sheet is determined according to the reclaimed rubber's own indicators and the performance requirements of the oil-resistant rubber sheet.
3. Tire reclaimed rubber
Tire reclaimed rubber is the product with the largest output and lower price in reclaimed rubber products. It is usually used in combination with nitrile rubber in the production of nitrile and oil-resistant rubber sheets. Because the tire reclaimed rubber itself does not have oil resistance, when using tire reclaimed rubber in the oil-resistant rubber sheet with nitrile rubber as the main raw material to reduce the cost, too much tire reclaimed rubber will cause the oil resistance of the oil-resistant rubber sheet to decrease, which is controlled at 40 Between -60 servings is appropriate. Tire reclaimed rubber can not only reduce the raw material cost of nitrile rubber sheet, but also solve the problem of easy roll-off during nitrile rubber mixing.
4. Recycled rubber powder
Compared with the production of reclaimed rubber, the production process of reclaimed rubber powder is simpler and more environmentally friendly. In actual production, manufacturers of nitrile and oil-resistant rubber sheets can use rubber powder in an appropriate amount in the formulation. Compared with low-priced fillers, reclaimed rubber powder has better compatibility with nitrile rubber 2LLYY826. Reasonable use will not affect the physical properties of oil-resistant rubber sheets, but will also improve the production process of nitrile rubber sheets to a certain extent and reduce the cost. More production costs.
There are many raw materials to reduce the production cost of nitrile oil-resistant rubber sheet, and the rubber sheet manufacturer can decide according to actual needs. In actual production, the influence of the formula on the various indicators of the oil-resistant rubber sheet is not weaker than that of the original rubber. Manufacturers need to adjust the production cost of the nitrile rubber sheet in time to optimize product performance while reducing costs. If possible, oil-resistant rubber sheet processing companies can also choose to use the above-mentioned low-priced raw rubbers together to reduce more raw material costs while ensuring product quality.
