NBR is not typically recommended for direct food contact applications due to potential concerns about the leaching of chemicals and additives. However, specialized grades of NBR that meet specific regulatory requirements may be suitable for certain indirect food contact applications, such as gaskets and seals in food processing equipment.
Nitrile rubber is highly durable and can withstand harsh environmental conditions, including exposure to chemicals and oils. Its ability to resist wear and tear makes it suitable for use in applications that require long-term performance.
While NBR is considered relatively safe for most industrial and commercial applications, there may be concerns related to potential exposure to hazardous chemicals during NBR manufacturing processes or when handling NBR-containing products.
NBR is generally not biodegradable and can be challenging to recycle due to its complex chemical structure and the presence of additives. However, some efforts are being made to develop recycling processes for NBR waste, such as mechanical and chemical recycling methods.
