Overview
Recycled Polyurethane Red is an environmentally friendly material produced by reprocessing post-industrial or post-consumer polyurethane waste. It retains the functional and aesthetic properties of virgin polyurethane, such as elasticity, durability, and vivid coloration, while minimizing resource consumption. The recycling process involves sorting, cleaning, and recompounding PU scraps into reusable granules or powder. This material aligns with circular economy principles, offering industries a sustainable alternative without compromising performance. It is particularly popular in sectors prioritizing eco-conscious production, such as automotive, construction, and consumer goods.
Physical and Chemical Properties
Recycled Polyurethane Red exhibits similar properties to virgin PU, including high tensile strength (20–50 MPa) and elongation at break (300–600%). Its density ranges from 1.1–1.3 g/cm³, and it maintains stability under temperatures up to 120°C. The vibrant red pigment is resistant to UV fading, making it suitable for outdoor applications. Chemically, it resists oils, greases, and mild acids but may degrade in strong alkaline environments. Its insolubility in water ensures longevity in humid conditions. Processability varies with formulation; some grades are optimized for injection molding, while others are tailored for coatings or adhesives.
Main Applications
The material is widely used in CASE applications (Coatings, Adhesives, Sealants, Elastomers) due to its adhesion and flexibility. In automotive industries, it serves as a coating for dashboards or interior trim, offering scratch resistance and aesthetic appeal. Footwear manufacturers utilize it for soles and decorative elements. Construction sectors employ it in sealants for joints and insulation panels. Consumer goods like furniture and sports equipment benefit from its durability and colorfastness. Niche uses include art supplies and theatrical props, where its non-toxicity and vivid hue are advantageous.
Safety and Storage
Recycled Polyurethane Red is generally safe when handled properly. Processors should wear PPE (gloves, masks) to avoid dust inhalation during grinding or mixing. Cured products are inert and pose no health risks. Storage requires protection from moisture and extreme temperatures to prevent clumping or degradation. Keep containers sealed and away from oxidizing agents. Shelf life typically exceeds 12 months under optimal conditions. Disposal should follow local regulations for polymer waste, though recycling is preferred to maintain sustainability.
B2B Procurement Guide
Buyers should prioritize suppliers with transparent recycling processes and certifications like ISO 14001 or GRS (Global Recycled Standard). Key evaluation criteria include color consistency (measured by Pantone or RAL codes), mechanical property datasheets, and recycled content percentage (commonly 70–100%). Bulk orders (1+ tons) often qualify for discounts, with prices influenced by pigment quality and PU grade. Samples are recommended to test compatibility with existing production lines. Logistics considerations include moisture-proof packaging and preferred shipping methods (e.g., palletized goods for large quantities).
