Did you mean: Neoprene chloroprene Rubber CR 2481
AI Overview
Neoprene Chloroprene Rubber CR2481 is a specialized grade of mercaptan-modified polychloroprene rubber, typically appearing as off-white or yellowish chips or sheets. It is widely recognized for its fast crystallization rate and high cohesion strength, making it a key material in the adhesives industry, particularly for high-bonding strength applications.
Key Characteristics of CR2481
- Modification: It is a mercaptan-modified type, which contributes to its specific processing characteristics.
- Crystallization Rate: Fast, which allows for rapid strength development.
- Adhesion Strength: High, similar to products like Denka A-90S or DuPont ADG.
- Physical Appearance: Off-white or yellowish chips/sheets.
- Density: Approximately .
Primary Applications
CR2481 is primarily used in the production of high-performance chloroprene adhesives. These adhesives are used in:
- Footwear: Bonding PVC, PU, and EVA materials.
- Industrial Applications: Adhesives for rubber, metal, leather, and wood.
- Construction: Adhesives for construction materials.
General Properties of CR Rubber (including CR2481)
- Resistance: Excellent resistance to ozone, aging, and weathering.
- Oil Resistance: Moderate to high resistance to oils, greases, and chemicals.
- Flame Retardancy: Good, often self-extinguishing.
- Temperature Range: Generally functional from to.
Similar Grades
CR2481 is often grouped with other high-performance adhesives grades such as:
- CR244 / CR2442: Other fast-crystallizing, mercaptan-modified types.
- CR2482: Similar high-cohesion grades.
- Denka A-90S / ADG: Equivalent industry standards.
