5 Key Differences Between IIR Rubber Sheets and NBR Rubber Sheets

5 Key Differences Between IIR Rubber Sheets and NBR Rubber Sheets

Both IIR and NBR rubber sheets are popular choices in various industrial applications, such as gaskets, seals, flooring, and waterproofing. However, these two types of rubber sheets have distinct properties that make them suitable for different uses. Here are the main differences between IIR and NBR rubber sheets

1) Gas Permeability
IIR Rubber Sheets : Known for their superior gas impermeability, IIR rubber sheets can resist gas penetration better than NBR rubber sheets.

NBR Rubber Sheets :While NBR rubber sheets also offer good gas impermeability, they do not match the high level of resistance provided by IIR rubber sheets.

2) Oil Resistance
IIR Rubber Sheets : These sheets are resistant to vegetable oils, animal fats, and synthetic hydraulic oils but are less effective against petroleum oils and fuel oils.

NBR Rubber Sheets : NBR rubber sheets excel in oil resistance, particularly against petroleum-based oils and hydrocarbons, making them ideal for applications involving such substances.

3) Chemical Resistance
IIR Rubber Sheets : Offer superior chemical resistance compared to NBR rubber sheets, making them suitable for environments with exposure to various chemicals.

NBR Rubber Sheets : While resistant to many chemicals, NBR rubber sheets do not perform as well as IIR rubber sheets in highly aggressive chemical environments.

4) Ozone Resistance
IIR Rubber Sheets : Exhibit excellent resistance to ozone and environmental conditions, outperforming NBR rubber sheets in this regard.

NBR Rubber Sheets : Although NBR rubber sheets provide good resistance to environmental factors, they are not as effective as IIR rubber sheets in resisting ozone.

5) Operating Temperature Range
IIR Rubber Sheets : Have a broader operating temperature range, from -50°C to +150°C, allowing them to withstand both extreme cold and heat better than NBR rubber sheets.

NBR Rubber Sheets : Their operating temperature range is from -35°C to +120°C, which is narrower compared to IIR rubber sheets.

Choosing the Right Rubber Sheet
The choice between IIR and NBR rubber sheets depends on your specific application and required properties. For applications involving oil and hydrocarbon solutions, NBR rubber sheets are the ideal choice. However, if you need a material that offers excellent gas impermeability, ozone resistance, and a wide operating temperature range, IIR rubber sheets are the best option.
