Nitrile rubber (NBR) o-rings, also known as Buna N, are one of the most commonly used sealing elastomers due to resistance to petroleum-based fuels and lubricants and its relatively low price. Nitrile elastomers are copolymers of acrylonitrile and butadiene. There are a number of common variations of nitrile compounds.

Rattan furniture maintenance method
1. Do not let it come into contact with or close to fire and heat sources during use and storage, and do not expose it to the sun for a long time, otherwise it will easily fade, dry out, deform, bend, crack, loose and disconnect.
2. Because there are many places for hiding ash on the surface of rattan furniture, you can use a vacuum cleaner to clean it first or use a soft brush to remove the floating dust from the inside out, then wipe it with a damp cloth, and finally dry it with a soft cloth .
3. After using for a period of time, wipe the rattan utensils with light salt water, which can not only decontaminate but also make it flexible and lasting, and also has a certain effect of preventing brittleness and insects.
4. Refurbishment method of primary color rattan furniture: first clean and dry, then sand the outer rattan frame with sandpaper to decontaminate and restore smoothness of the skin, and then protect it with varnish.
5. Avoid direct sunlight for a long time and avoid being close to fire sources to prevent the rattan material from fading, drying, deforming, bending, cracking, loosening and disengaging.
6. When cleaning, you can suck it with a vacuum cleaner first, or use a soft brush to remove the floating dust from the inside out, then wipe it with a damp cloth, then wipe it with a soft cloth.
7. After being used for a period of time, it can be wiped with fresh salt water, which can not only decontaminate but also maintain its flexibility for a long time, and also has a certain effect of preventing brittleness and insects.

Acrylonitrile Content
The acrylonitrile (ACN) content of the polymer chains can vary from 18% to 50%. Lower ACN content gives better low-temperature properties but inferior resistance to fuels and polar lubricants. Higher ACN content gives lesser quality low-temperature properties but improved fuels and polar lubricants resistance. Standard NBRs typically have 34% ACN content.
Standard Nitrile o-rings are usually sulfur-cured. Sulfur-cured compounds offer better low-temperature properties but are more prone to hardening with high temperatures. Peroxide-cured nitrile o-rings have better heat resistance and lower compression sets but are more expensive and more difficult to process.
Buna O-rings, Nitrile O-rings, NBR O-rings offer excellent sealing and mechanical properties at low cost. Buna Nitrile O-rings have resistance to common lubricants and are recommended for crude oil, gasoline, propane, petroleum oils and water. Nitrile Buna O-rings are used in engines, gearboxes, aircraft pumps, and water applications.
Rattan furniture maintenance tips
Jade rattan furniture also plays an important role in ecology. It can not only adapt to degraded forests and poor soil, but also grow well in natural forests without disturbing the original ecological structure and balance. The form is very unique, and the unique appeal created by the traditional handicrafts it displays, therefore, it is greatly obscured by its elegant and concise appearance around the world. Moreover, it has undergone strict processing. No pollution, it can be recycled.
