Description

Thermoplastic Polyurethanes CAS NO 1211-14-9 represent a versatile class of elastomeric polymers known for their exceptional combination of high elasticity, toughness, and processability. This material matters for engineers and designers seeking a durable, flexible solution that bridges the gap between rigid plastics and soft rubbers. Key industries that need it include automotive manufacturing for interior components and seals, consumer goods for high-wear items like shoe soles and phone cases, and industrial sectors for hoses, gaskets, and cable jacketing.

Application

• Automotive Components: Used in the production of interior trim, dashboard skins, door panels, and weather-resistant seals and gaskets.
• Consumer Goods & Footwear: Ideal for manufacturing durable, flexible shoe soles, watch straps, protective phone cases, and sports equipment.
• Industrial Hose & Tubing: Serves as a key material for flexible hoses, pneumatic tubing, and hydraulic lines requiring oil and abrasion resistance.
• Wire & Cable Jacketing: Provides excellent insulation, flexibility, and mechanical protection for cables in demanding environments.
• Medical Device Components: Utilized in non-implantable medical tubing, catheter shafts, and device housings where biocompatibility grades are specified.
• Industrial Rollers & Wheels: Formulated into high-performance rollers, conveyor belt components, and casters for material handling.
• Adhesives & Sealants: Acts as a base polymer for high-strength, flexible adhesives and construction sealants.
• Extruded Profiles & Films: Processed into custom profiles for gasketing and protective films for laminates.

Quality Control

Our Thermoplastic Polyurethanes are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Quality is verified through a comprehensive suite of tests including intrinsic viscosity, melt flow index (MFI), hardness (Shore A/D), tensile strength, and elongation at break. Certificates of Analysis (COA) detailing lot-specific results are provided with every shipment. We can supply grades compliant with relevant industry standards such as ISO, USP Class VI (for medical applications), and FDA regulations for indirect food contact where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept in its original, unopened packaging until use to prevent moisture absorption, which can affect processing and final properties. Keep away from strong acids, bases, and oxidizing agents.
