Description

Poly Urethane CAS NO 51852-81-4 is a versatile polymer belonging to the polyurethane family, known for its exceptional durability, flexibility, and resistance to abrasion and chemicals. This material is critical for creating high-performance products that require a unique balance of toughness and elasticity. It is an essential raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing flexible and rigid foams.

Application

• Protective Coatings & Paints: Formulating high-performance industrial and marine coatings, floor finishes, and wood varnishes that offer superior gloss, chemical resistance, and weatherability.
• Adhesives & Sealants: Manufacturing structural and flexible adhesives for automotive, construction, and footwear assembly, providing strong bonds and excellent gap-filling properties.
• Elastomers & Thermoplastic Polyurethane (TPU): Producing durable components such as wheels, gaskets, hoses, and synthetic leather for automotive, industrial, and consumer goods.
• Flexible & Rigid Foams: Used as a key component in the production of cushioning for furniture, mattresses, automotive interiors, and insulation panels for construction.
• Textile & Fiber Coatings: Applying durable, waterproof, and breathable coatings to fabrics for outdoor apparel, medical textiles, and technical fabrics.
• Composite Materials: Acting as a matrix resin in fiber-reinforced composites for lightweight, high-strength applications in aerospace and automotive sectors.

Quality Control

Our Poly Urethane is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Quality is verified through a series of analytical tests including viscosity, NCO/OH content, solids content, and mechanical property testing on cured samples. A Certificate of Analysis (COA) detailing specific lot results is provided with every shipment to guarantee compliance with your technical requirements.

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 / 59-77°F). This product is hygroscopic (moisture-sensitive). Keep containers tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from heat, sparks, and open flame.
