Description

Poly-α-Pinene CAS NO 70750-57-1 is a high-purity, polymeric form of α-pinene, a key terpene derived from pine trees. This specialized polymer offers enhanced stability and tailored physical properties compared to its monomeric counterpart, making it a valuable intermediate and functional material. It is essential for manufacturers in the fragrance, adhesive, resin, and specialty chemical industries seeking consistent performance and reliable supply for their formulations.

Application

• Fragrance and Flavor Industry: Serves as a base material for creating stable, long-lasting woody and pine-like aroma chemicals and fixatives.
• Adhesive and Tackifier Formulation: Used in the production of modified resins and tackifiers for pressure-sensitive and hot-melt adhesives.
• Polymer and Resin Modification: Acts as a reactive intermediate or modifier to alter the properties of synthetic resins, improving flexibility or compatibility.
• Specialty Chemical Synthesis: A key starting material for the synthesis of higher-value terpene-based chemicals, including antioxidants and plasticizers.
• Industrial Cleaning and Solvents: Employed in formulated cleaning products and solvent blends where a stable, high-boiling terpene fraction is required.
• Coatings and Inks: Used as a modifier in coating formulations to enhance specific characteristics like gloss or adhesion.

Quality Control

Our Poly-α-Pinene is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, viscosity, and chemical composition. A detailed Certificate of Analysis (COA) documenting key parameters is provided with every shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). As this material is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flame.
