Description

Poly(Isoprene), Cis, Average M.W. 800.000 is a synthetic, high-purity polymer that replicates the structure of natural rubber. This material is valued for its excellent elasticity, low-temperature flexibility, and high resilience, making it a critical component in advanced formulations. It is essential for manufacturers in the adhesives, sealants, specialty rubber goods, and biomedical device industries seeking consistent, high-performance raw materials.

Application

• High-Performance Adhesives & Sealants: Serves as a key tackifier and elastomeric base for pressure-sensitive and structural adhesives.
• Specialty Rubber Compounding: Used in the formulation of medical-grade tubing, gaskets, and vibration-damping components.
• Polymer Modification & Blends: Acts as an impact modifier and compatibilizer in engineering plastics and thermoplastic elastomers (TPEs).
• Biomedical & Pharmaceutical Applications: Employed in controlled drug delivery systems and as a component in biocompatible matrices.
• Consumer Goods: Found in high-quality erasers, chewing gum bases, and sporting goods.
• Industrial Coatings & Mastics: Provides flexibility and durability in protective coatings and caulking compounds.

Quality Control

Our Poly(Isoprene) is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Each lot is tested against stringent in-house specifications for parameters such as molecular weight distribution, cis-content, and purity. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and physical properties is provided with every shipment to support your quality assurance protocols.

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). This product is easily oxidized; for long-term storage, it is recommended to keep under an inert atmosphere (e.g., nitrogen) to preserve its properties. Keep away from heat sources and open flames.
