Nitrile reclaimed rubber quality judgment

Nitrile reclaimed rubber is the best reclaimed rubber with excellent oil resistance. It is used in the production of various oil-resistant rubber products such as oil-resistant rubber shoes, oil-resistant aprons, oil-resistant pipes, oil seals, and oil rollers. The first step to ensure the quality of rubber products using nitrile rubber reclaimed rubber is to choose high-quality nitrile reclaimed rubber, which is the voice of the majority of rubber products companies. So how do you judge the quality of nitrile regenerated rubber products?

As with all reclaimed rubbers, when selecting nitrile reclaimed rubber, the quality of the nitrile regenerated rubber product can be determined first by appearance, which is often referred to as the visual inspection method. The quality of the nitrile regenerated rubber product is observed to be uniform and the surface contains impurities (including Whether metal chips, wood chips, sand, and fine fibers, etc., or sticking between film and film.

In addition, rubber product manufacturers can cut a small amount of products from the nitrile reclaimed rubber film, try the elasticity and tensile strength of the nitrile reclaimed rubber products by hand, and observe the fineness of the nitrile reclaimed rubber at the cut surface, whether it contains impurities, etc.

This is only a preliminary judgment of the quality of nitrile reclaimed rubber products. If you want to accurately understand the various physical and chemical indexes of nitrile reclaimed rubber, you can conduct inspections through professional testing instruments. The testing indicators for nitrile regenerated rubber include: Strength, elongation at break, hardness, density and other physical indicators, heating reduction, ash, acetone extracts, moisture, volatile matter, rubber hydrocarbon content, carbon black content, sulfur content and other chemical indicators, nitrile reclaimed rubber products Mooney viscosity, plasticity and other technical indicators; if you want to buy environmentally friendly nitrile reclaimed rubber, you also need to carry out environmental indicators testing of reclaimed rubber, including lead (Pb), mercury (Hg), cadmium (Cd), hexavalent cadmium ( Detection of harmful substances such as Cr6+), polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE).

The above are all conventional methods for judging the quality of nitrile reclaimed rubber, applicable to all reclaimed rubber; as the main force in the production of oil-resistant rubber products, customers can also carry out special function tests on the oil resistance of nitrile reclaimed rubber (including nitrile reclaimed rubber Oil resistance, high/low temperature resistance of EPDM, airtightness of butyl regenerated rubber, etc.) to see if it meets the performance requirements of your own product.

In fact, when rubber products manufacturers choose reclaimed rubber products, they must not only judge the quality of reclaimed rubber products, but also need to consider the size of reclaimed rubber manufacturers, production equipment, technical services, etc., and the quality of reclaimed rubber products produced by regular reclaimed rubber factories is more stable. , easily without quality fluctuations or out of stock, out of stock problems, and even can be customized according to specific needs of a variety of renewable rubber products.
