High-Quality NBR FKM EPDM Silicone O-Ring Seals From China

Product Description

Product Description

HNBR (Hydrogenated Nitrile Butadiene Rubber) is a high-performance elastomer produced by hydrogenating standard NBR (Nitrile Rubber). This process enhances its resistance to heat, ozone, chemicals, and abrasion while retaining excellent mechanical properties. HNBR is widely used in demanding environments due to its superior balance of durability, flexibility, and resistance to extreme conditions. Its key attributes include exceptional thermal stability (up to 150°C/302°F), strong resistance to oils and fuels, and improved aging characteristics compared to conventional NBR. These properties make it ideal for critical sealing applications across industries such as automotive, oil and gas, and aerospace.

HNBR Material: Industry Applications and Performance Analysis

Performance Attribute	Industry Applications	Key Characteristics
Thermal Resistance	Automotive engines, aerospace components, industrial machinery	Operates in temperatures from -40°C to 160°C (-40°F to 320°F); resists thermal degradation and aging.
Chemical/Oil Resistance	Oil & gas drilling equipment, fuel systems, hydraulic seals	Excellent resistance to oils, fuels, acids, and chemicals; minimal swelling in harsh fluids.
Mechanical Strength	Dynamic seals, O-rings, gaskets, belts	High tensile strength (20-30 MPa) and elongation (200-400%); resists wear and abrasion.
Ozone/Weather Resistance	Outdoor equipment, electrical connectors, HVAC systems	Withstands UV exposure, ozone, and weathering; maintains flexibility in outdoor environments.
Compression Set Resistance	Static seals, vibration dampeners, pump components	Low compression set (15-25% at 150°C) ensures long-term sealing efficiency under pressure.
Dynamic Performance	Automotive timing belts, rotary shafts, industrial hoses	Retains elasticity and fatigue resistance under cyclic stress; ideal
