- Sheets: 3'3" x 16'4" long, with 3/8" to 5/8" thickness
Transformer grade nitrile of the highest quality due to its mechanical properties and resistance to oils, greases, hydrocarbons and excellent for making all types of gaskets and flanges that are in contact with the oil of distribution and power transformers; excellent resistance to environmental aging, meets the standards required by manufacturers of transformers, this type of rubber is also useful in automotive gaskets.
Applications
Used to pack transformers, transformer gaskets that comply with the standard established by the Comisión Federal de Electricidad in Mexico. For electrical insulation, see dielectric rubber.
Frequently Asked Questions about Nitrile for Electrical Transformers
What is transformer grade nitrile?
Transformer grade nitrile (NBR) is a specially formulated nitrile rubber with maximum quality mechanical properties and excellent resistance to oils and greases. It is designed to meet the chemical and mechanical requirements of distribution and power transformer manufacturers.
What are nitrile gaskets used for in transformers?
Nitrile gaskets are used to seal distribution and power transformers, preventing oil leaks and protecting internal components. They must tolerate weathering, abrasion and acids, while offering excellent resistance to the oil used in transformers.
What is the temperature range of transformer grade nitrile?
Transformer grade nitrile has a temperature range of -13°F to 248°F (-25°C to 120°C). It offers excellent oil resistance, medium acid resistance, good outdoor resistance and good abrasion resistance.
Does your nitrile comply with CFE standards?
Yes, our transformer grade nitrile is used in Mexico to manufacture gaskets for distribution and power transformers, meeting the chemical and mechanical requirements of the Federal Electricity Commission (CFE).
