Regular PU Sponge
Composition:
Regular PU Sponge is crafted from polyurethane, formed through the reaction of isocyanates and polyols, combined with catalysts, stabilizers, and foaming agents. The resulting foam undergoes precise parameter control to achieve properties such as density, hardness, and flexibility. Its porous structure combines open and closed cells, offering exceptional softness, elasticity, and durability. This versatility allows it to be customized into various shapes, including squares, circles, and textured patterns like waves or diamonds, as well as vibrant colors such as yellow, green, and blue.
PU sponges are widely used across industries, from household cleaning (kitchens, bathrooms) to automotive maintenance and industrial applications. They are available with smooth or textured surfaces to meet diverse needs, and eco-friendly formulations, antibacterial treatments, and flame-resistant options further enhance their functionality. Packaging options include bulk, compressed, or individual retail-ready formats, offering flexibility for both wholesale and consumer markets.

Characteristics
Soft and Elastic
Regular PU Sponge is highly flexible and elastic, maintaining its shape and performance even after repeated use and compression, making it ideal for long-term applications.
Open and Closed Cell Structure
The combination of open and closed cells offers a balance of breathability and strength. Open cells provide excellent absorbency, while closed cells enhance durability and rigidity for tougher tasks.
Lightweight and Durable
Its lightweight nature ensures ease of handling, while its durability makes it resistant to wear and tear, even under rigorous conditions.
Customizable Options
Available in various shapes, colors, and surface designs (smooth or textured), it can be tailored to meet specific cleaning and industrial needs, offering both aesthetic and functional versatility.
Eco-Friendly and Safe
Eco-conscious formulations, such as low VOC emissions or biodegradable materials, make it a sustainable choice. Antibacterial and flame-resistant treatments further enhance its safety and usability.
Multi-Purpose Usability
Ideal for a wide range of applications, including household cleaning (kitchens, bathrooms), automotive maintenance, and industrial uses like packaging, filtration, and cushioning.
Excellent Cleaning Performance
With its porous structure and high absorbency, it effectively captures and removes dirt, grease, and residues, providing superior cleaning results.
Manufacturing
Regular PU Sponge is produced through a precise and efficient manufacturing process, ensuring consistency and versatility. The process begins with the reaction of isocyanates and polyols, combined with catalysts, stabilizers, and foaming agents, to create a polyurethane base. Advanced foaming techniques are used to develop the porous structure, which can be tailored for varying densities, hardness, and flexibility.
PU Sponge Manufacturing Process：
- Polyurethane raw materials (isocyanates, polyols, and additives) are mixed and injected into molds for chemical foaming.
- Foam parameters are adjusted to achieve desired hardness, density, and flexibility.
- Cutting: Sponges are cut into blocks, sheets, strips, or other shapes as required.
- Compression: Compressed into thin sheets for easier transportation and storage.
- Composite: Combined with other materials (e.g., abrasive cloth) for dual-sided cleaning functions.
- Special Treatments: Includes antibacterial, fireproof, and flame-retardant treatments to meet specific needs.
From Regular PU Sponge to Practical Applications
Shapes and Sizes:
- Regular shapes: Squares, circles, strips, etc.
- Special shapes: Waves, diamond patterns, triangles to suit specific cleaning tasks.
Surface Design:
- Smooth surface: For general wiping and cleaning tasks.
- Composite surface: Combined with abrasive or fiber cloth to enhance cleaning power for stubborn stains.
Color Options:
- Single colors: Common options include yellow, blue, and green for a clean and simple look.
- Multi-colors or patterns: Useful for categorization (e.g., kitchen-specific, bathroom-specific).
Packaging Options:
- Bulk packaging: Ideal for large-scale procurement.
- Individual packaging: Each sponge is individually wrapped for retail convenience.
- Compressed packaging: Saves transportation space and restores original shape upon use.
