Description

Fluoroelastomers CAS NO 64706-30-5 are a class of high-performance synthetic rubbers renowned for their exceptional resistance to harsh chemicals, high temperatures, and aggressive environments. This makes them a critical material for sealing and fluid handling components where standard elastomers fail. Industries such as aerospace, automotive, chemical processing, and oil & gas rely on these materials for reliable, long-term performance under extreme operating conditions.

Application

• O-Rings, Gaskets, and Seals for chemical processing equipment, fuel systems, and hydraulic systems.
• Automotive Components including shaft seals, valve stem seals, and hoses exposed to hot oils and fuels.
• Aerospace Sealing Solutions for jet engines, fuel systems, and hydraulic systems requiring performance at high altitudes and temperatures.
• Oil & Gas Downhole Equipment such as packers, blow-out preventer seals, and valve seals resistant to sour gas (H2S) and high-pressure/high-temperature (HPHT) conditions.
• Semiconductor Manufacturing components like wafer carrier seals and diaphragm valves for high-purity processes.
• Industrial Hose and Diaphragms for handling aggressive solvents, acids, and bases.

Quality Control

Our fluoroelastomers are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as monomer ratio, molecular weight, and cure characteristics are rigorously controlled. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing specifications relevant to processing and end-use performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. Protect from moisture to prevent premature curing or degradation of polymer properties.
