Did you mean: Neoprene chloroprene Rubber CR 3221
AI Overview
Key Characteristics and Properties
- Composition: Sulfur and xanthogen modified chloroprene rubber, providing a medium crystallization rate.
- Appearance: Beige or brown lumps/chips.
- Processability: Better than typical sulfur-modified grades, but requires strict temperature control (25°C or lower) to prevent sticking, as it can be difficult to manage if overheated during mixing.
- Performance: High tear resistance, high tensile strength (), and high elongation ().
- Resistance: Excellent resistance to ozone, aging, and weather.
- Density: .
- Similar Grades: Often compared to Dupont's GW or Denka's DCR-40.
Common Applications
- Electrical/Cable: Cable sheaths and industrial wiring.
- Industrial/Automotive: Conveyor belts, timing belts, V-belts, and automotive components.
- General Products: Seals, dust covers, and rubber hoses.
Processing and Handling
- Mixing: Used in open mills, often requiring plasticization of the chips, which is enhanced by low-viscosity, high-viscosity properties.
- Storage: Should be stored at temperatures below 25°C to maintain stability for up to one year.
- Formulation: Usually requires zinc oxide for vulcanization.
CR3221 is widely utilized for its balance of high tear strength and easier,, faster processing compared to older sulfur-modified chloroprene rubbers.
