Description

Our Recycle-Sponge Binder is a high-quality polyurethane adhesive used to transform waste industrial sponge scraps and crushed cotton into specialized regenerated foam. By mixing these crushed particles with our glue in specific proportions, manufacturers can create durable, eco-friendly materials that meet the rigorous demands of various commercial sectors.

The resulting rebonded foam products are characterized by their superior physical properties, including strong recovery from deformation and high structural integrity. Depending on the specific grade chosen, the adhesive can facilitate quick reaction times for efficient manufacturing or provide specific hardness levels to suit the end-product's requirements.


Technical Specifications

Article Grade NCO Content (%) Viscosity (mPa⋅s 25°C) Color Performance Characteristics
JS-106#-1 2.3% ~ 2.7% 35 ~ 45 Light Yellow Good tensile strength with a moderate soft degree.
JS-118#-1 2.9% ~ 3.7% 50 ~ 80 Light Yellow Enhanced strong tensile strength for durable foam.
JS-128#-1 5.3% ~ 5.8% 30 ~ 50 Light Yellow Quick reaction, strong hardness, and good tensile strength.


Key Features & Benefits

  • Sustainability: Enables the recycling of waste materials into valuable industrial components.

  • Customizable Hardness: Multiple grades allow for the production of foam ranging from moderate softness to strong hardness.

  • Superior Tensile Strength: Ensures the final rebonded foam does not tear easily under stress.

  • Excellent Resilience: Products maintain their shape and support over long-term use.

  • Optimized Viscosity: Low to moderate viscosity range (30-80 $mPa\cdot s$) ensures easy mixing and thorough coating of sponge particles.


Applications

  • Furniture Industry: Ideal for rebonded foam used in sofas, mattresses, and cushions.

  • Automotive Sector: Used in car seat manufacturing and interior padding.

  • Household Necessities: Production of sponges for various domestic and industrial cleaning or padding uses.

  • Office Furniture: High-resilience seating components and office chair padding.
