AI Overview
Chloroprene Rubber CR1211 (often referred to as CR121 or CR-121) is
a sulfur-modified, general-purpose synthetic rubber known for its medium-low crystallization rate, beige appearance, and high tensile strength
. It offers excellent tear resistance, flexure fatigue resistance, and, similar to DuPont’s Neoprene GNA, is commonly used in heavy-duty products like conveyor belts, mining cables, and automotive hoses
.
Key Characteristics and Properties
- Structure: Sulfur-modified polychloroprene produced via emulsion polymerization.
- Crystallization Rate: Medium-low, providing good processing stability.
- Appearance: Beige-white chips or lumps.
-
Density:
Approximately
.
- Performance: High oil resistance, heat resistance, and aging resistance, along with self-extinguishing flame properties.
- Similar Materials: It is considered equivalent to DuPont's Neoprene GNA/GN and Denka’s PM-40.
