Description

Bicyclo[2.2.1]Hept-2-Ene, 5-Ethylidene-, Polymer With 1-Butene And Ethene is a high-performance, specialty ethylene-propylene-diene monomer (EPDM) type terpolymer, known for its exceptional stability and elastic properties. This engineered material is critical for applications demanding superior resistance to environmental stressors such as heat, ozone, and weathering. It is primarily sought by manufacturers in the automotive, construction, and industrial rubber goods sectors for producing durable seals, gaskets, hoses, and roofing membranes.

Application

• Automotive Seals and Gaskets: Used in door seals, window channels, and trunk seals due to excellent weather and ozone resistance.
• Construction and Roofing Membranes: A key polymer in single-ply roofing systems for outstanding durability and waterproofing.
• Industrial Hose and Tubing: Formulated for hoses requiring flexibility and resistance to heat and chemical exposure.
• Plastic Modification and Impact Improvement: Acts as an impact modifier and compatibilizer in thermoplastic polyolefin (TPO) blends.
• Wire and Cable Insulation: Provides excellent electrical insulation properties and long-term environmental protection.
• Vibration Dampening Components: Used in engine mounts and anti-vibration pads for automotive and machinery.

Quality Control

Our Bicyclo[2.2.1]Hept-2-Ene, 5-Ethylidene-, Polymer With 1-Butene And Ethene is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including monomer content, Mooney viscosity, and thermal stability to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) detailing specific test results are available upon request.

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, sparks, and open flame. For long-term storage, maintain under an inert atmosphere such as nitrogen to prevent oxidation and cross-linking.
