Durable Oil-Resistant NBR Rubber Sheeting (70 Shore)
Material Overview
Nitrile Rubber (NBR), also commonly referred to as Buna-N, is a widely preferred elastomeric material renowned for its exceptional resistance to petroleum-based fuels and lubricants. Its cost-effective nature adds to its appeal. Nitrile rubber is essentially a copolymer formed from acrylonitrile and butadiene, resulting in various formulations.
Acrylonitrile Content
The acrylonitrile (CAN) content within the polymer chains can range from 18% to 50%. Lower CAN content contributes to superior low-temperature performance but may compromise resistance to fuels and polar lubricants. Conversely, higher CAN content yields better resistance to fuels and polar lubricants while sacrificing low-temperature qualities. Standard NBRs typically maintain a 34% CAN content.
Cure System: Sulfur-Cured
Standard Nitriles are commonly sulfur-cured. While this approach enhances low-temperature characteristics, it can lead to hardening at elevated temperatures. Alternatively, peroxide-cured nitriles exhibit improved heat resistance and reduced compression set, though they are relatively more costly and can be more challenging to process.
Applications
Nitrile rubber excels in a wide range of applications, including carburetor and fuel pump diaphragms, aircraft hoses, seals, gaskets, and oil-lined tubing. Its versatility and robust resistance make it suitable for applications requiring protection not only against oil and fuel but also against heat, abrasion, water, and gas permeation. From oil rigs to bowling alleys, nitrile rubber is an ideal choice for your specific needs.
