Description

Rubber, Synthetic, Acrylic CAS NO 67254-76-6 is a high-performance synthetic elastomer derived from acrylate monomers, offering a unique balance of oil, heat, and ozone resistance. This material is critical for applications demanding long-term durability in harsh chemical and thermal environments where traditional rubbers fail. It is essential for manufacturers in the automotive, industrial sealant, and specialty adhesive sectors seeking reliable sealing and gasketing solutions.

Application

• Automotive Seals and Gaskets: Used in transmission seals, valve stem seals, and O-rings exposed to hot oils and lubricants.
• Industrial Hose and Belting: Manufacture of hoses for fuel, oil, and hydraulic fluid transfer, as well as conveyor belts for high-temperature processes.
• Adhesives and Sealants: Formulation of high-performance, flexible sealants and adhesives for construction, aerospace, and appliance assembly.
• Oil Field Components: Production of packers, blow-out preventer seals, and other downhole equipment requiring resistance to sour gas and high temperatures.
• Roll Coverings and Printing Blankets: Used in industrial rollers and printing applications for its resilience and solvent resistance.
• Wire and Cable Jacketing: Provides protective insulation for cables in demanding environments.

Quality Control

Our acrylic rubber is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Quality is verified through a series of tests including Mooney viscosity, specific gravity, tensile strength, elongation, and compression set measurements. Certificates of Analysis (COA) detailing these parameters are available upon request to support your quality assurance protocols.

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 sources of heat, ignition, and direct sunlight. To prevent contamination, keep containers sealed when not in use.
