Vulcanization formulation of high-brightness oil-resistant rubber sealing ring produced from R-NBR

R-NBR is a recycled rubber raw material made from waste NBR. It is made of waste NBR through selection, crushing, desulfurization, filtration, refining and other processes to make sheet-shaped solid rubber products, which belongs to a kind of synthetic regenerated rubber.

Since R-NBR is mainly made of NBR waste, it has similar properties to NBR:

1. Excellent thermal stability and aging resistance. R-NBR also has a higher service temperature, generally as high as 150°C.

2. Excellent oil and chemical resistance. R-NBR has extremely strong resistance to various oils, solvents and chemicals.

3. Higher tensile strength and tear strength. R-NBR has high tensile strength and tear strength.

4. Good processing performance. The usage method of R-NBR is basically the same as that of NBR.

5. Good wear resistance and flex fatigue resistance. R-NBR has high wear resistance and flex fatigue resistance.

HONGYUN R-NBR has excellent properties similar to the original NBR. It has good stability and durability in high temperature, oil and chemical environments. It has high mechanical strength and good processing performance. It can be widely used in the manufacture of high performance And durable rubber products, is a high-performance synthetic rubber recycled rubber products.

In actual production, if oil-resistant rubber products require relatively high brightness, then R-NBR cannot be used alone as a raw material, and a part of sub-brand NBR or nitrile raw rubber must be used together to achieve the effect of being as bright as a mirror, of course it is good The mold is the basic premise. Generally, the surface of molded rubber products is brighter than that of extruded rubber products.

Using d05m06yyE3 R-NBR to produce rubber products can reduce the cost of raw materials, but the specific degree of reduction depends on the price and quality of R-NBR.

1. High-quality odorless R-NBR can reduce the cost of raw materials by 20% to 50%

2. The use of R-NBR to produce rubber products can also save a certain amount of electricity costs, because the processing temperature of recycled rubber is low, and the processing energy consumption is relatively small. The specific degree of savings depends on the scale of production and equipment conditions, and generally 5% to 10% of the cost of electricity and electricity can be saved.

3. The use of R-NBR to produce rubber products can also increase revenue, because the price of recycled rubber is relatively low, which can improve the competitiveness of products, increase sales and profits. The use of R-NBR can also reduce waste generation, reduce environmental protection costs, and improve corporate social responsibility.
