Description

Furan, Tetrahydro-, Polymer With Oxirane, Block is a specialized block copolymer derived from tetrahydrofuran and ethylene oxide (oxirane). This engineered polymer is valued for its unique combination of flexibility, hydrophilicity, and compatibility, making it a versatile intermediate and performance additive. It is primarily sought by formulators and manufacturers in the polyurethane, coatings, and specialty chemical industries seeking to modify material properties.

Application

• Polyurethane Systems: Used as a soft segment or chain extender to impart flexibility, improved hydrolytic stability, and low-temperature performance to elastomers, adhesives, and coatings.
• Surface Coatings & Inks: Acts as a rheology modifier and dispersing agent, enhancing flow, leveling, and pigment wetting in high-performance formulations.
• Specialty Elastomers & Sealants: Serves as a key polymeric component to achieve specific tensile strength, elongation, and resilience properties.
• Pharmaceutical & Cosmetic Excipients: Employed in controlled-release drug delivery systems and personal care products for its solubility profile and biocompatibility.
• Lubricant & Fuel Additives: Functions as a viscosity index improver and detergent additive to enhance performance and cleanliness.
• Chemical Intermediate: Utilized for further chemical reactions, such as cross-linking or functionalization, to create custom polymeric architectures.

Quality Control

Our production of Furan, Tetrahydro-, Polymer With Oxirane, Block adheres to stringent quality management protocols. Each batch is characterized for critical parameters including molecular weight distribution (polydispersity index), hydroxyl value, and ethylene oxide content to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting these specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) when not in use to prevent moisture absorption and potential degradation.
