In rubber product manufacturing, balancing material mechanical properties with processing efficiency remains one of the most significant challenges engineers face. For those seeking a universal additive that dramatically enhances product toughness, weather resistance, and process compatibility, CPE 135B stands as the industry's preferred solution.

As a premier member of the chlorinated polyethylene (CPE) family, CPE 135B represents more than just a high-performance synthetic rubber—it serves as a critical component for enhancing the core competitiveness of rubber products. Its unique molecular structure provides exceptional physicochemical properties, securing its indispensable position in formulations for wire cables, industrial hoses, and various high-performance rubber products.

Exceptional Compatibility and Processing Flexibility

CPE 135B's most notable advantage lies in its remarkable compatibility. It seamlessly integrates with multiple mainstream rubber materials, including CR (chloroprene rubber), CSM (chlorosulfonated polyethylene), NBR (nitrile rubber), EPDM (ethylene propylene diene monomer), SBR (styrene-butadiene rubber), and NR (natural rubber). Regardless of the base material requiring enhancement, CPE 135B can be blended in any proportion, allowing flexible formula adjustments based on end-product requirements while significantly reducing research and production complexity.

Key Technical Parameters Explained

To ensure product stability under demanding conditions, CPE 135B maintains exceptionally high physical standards:

• Chlorine Content (35%): Precisely engineered chlorine levels achieve optimal balance between flame retardancy, oil resistance, and physical strength.
• Thermal Stability (165 min): The extended 165-minute thermal stability window provides ample tolerance for high-temperature processing in complex manufacturing processes, effectively preventing degradation risks.
• Mechanical Performance: With 8.0 MPa tear strength combined with 800% elongation at break, the material delivers exceptional fatigue and deformation resistance. A 60 Shore A hardness ensures products maintain sufficient structural support while preserving flexibility.
• Processing Characteristics: The precisely controlled 70 Mooney viscosity (ML91+40) ensures excellent flow properties while enhancing operational stability during extrusion and molding processes. Additionally, 0.4% volatile content and 0.55 g/ml apparent density further optimize material feeding and mixing efficiency.

Industry Applications and Value

In wire and cable applications, CPE 135B's low crystallinity gives sheath materials outstanding flexibility and environmental stress crack resistance. For industrial hose manufacturing, its superior chemical resistance and anti-aging properties significantly extend product service life while reducing maintenance costs. Whether pursuing ultimate wear resistance or enhanced tear resistance, CPE 135B's stable physical characteristics ensure product quality protection.

As demonstrated, CPE 135B transcends being a simple additive—it represents a strategic material for optimizing rubber formulations and elevating product quality. Through its exceptional compatibility and reliable mechanical properties, it enables manufacturers to achieve simultaneous improvements in both production efficiency and product performance.
