Products Description
HNBR (Hydrogenated Nitrile Butadiene Rubber) stands out for its exceptional resistance to heat, oil, and dynamic stress, making it a preferred choice across industries such as automotive, oil and gas, and manufacturing.
Dawn's HNBR Elastomer offerings are categorized into specialized grades, each formulated to address specific industry challenges. Let's explore our key product grade and their applications:
Product Series
HNBR Elastomer
DN3408
DN3408 is engineered with outstanding heat resistance, making it ideal for applications where high temperatures are a constant factor. It finds extensive use in synchronous belts, multi-ribbed belts, O-rings, gaskets, and seals. Its ability to maintain mechanical integrity under extreme heat ensures prolonged service life, reducing downtime and replacement costs in automotive and industrial settings.
01
DN3418
As a medium-to-high nitrile content grade, DN3418 excels in both dynamic performance and ease of processing. This versatility makes it a go-to choice for synchronous belts, O-rings, gaskets, oil seals, and petroleum industry components. Its robust mechanical properties and adaptability to various manufacturing processes make it suitable for applications requiring both precision and durability.
02
DN3428
DN3428 is designed to withstand harsh conditions, particularly in low-temperature environments. Its exceptionally low-temperature compression set resistance and superior oil resistance make it indispensable for oil-resistant seals, rubber rollers, and dynamic components in the oil and gas sector. Whether in subzero climates or high-pressure oil fields, DN3428 ensures reliable performance.
03
DN3448
DN3448, with its low saturation levels, is specifically formulated for dynamic environments where flexibility and resilience are critical. It is widely used in rubber rollers, dynamic seals, and other applications requiring resistance to repeated stress and deformation. Its unique composition ensures long-lasting performance in high-movement scenarios.
DN3406
DN3406 offers a well-rounded performance profile, combining excellent heat resistance, media resistance, and extrusion capabilities. This grade is suitable for a broad range of applications, including synchronous belts, multi-ribbed belts, O-rings, gaskets, and seals. Its adaptability to various manufacturing processes makes it a versatile choice for diverse industrial needs.
