Bio-based polyurethane foam scrubber with enhanced abrasion resistance and durability

Overview

This solution offers a customizable polyurethane foam technology designed for scrubbing and cleaning applications where abrasion resistance and durability are critical. By incorporating microfillers and bio-based raw materials into the foam formulation, the technology delivers enhanced mechanical performance while supporting sustainability goals. The foams can be tuned from soft and flexible to semiflexible structures depending on the intended end use, giving manufacturers flexibility to match product requirements across a range of cleaning and surface-care applications.

The approach combines two value drivers: improved functional performance through controlled cellular morphology and reduced environmental footprint through renewable content. This makes the technology attractive for consumer goods, industrial cleaning products, and manufacturers seeking to differentiate on durability and sustainability.

Technical specifications

Key features:

• Microfillers integrated into the polyurethane matrix to enhance abrasion resistance and wear behavior
• Formulation flexibility enabling soft flexible to semiflexible foam structures through adjustment of composition
• Bio-based content that contributes to sustainability and biodegradability of the final foam
• Controlled cellular morphology achieved by varying filler percentage
• Tunable thermo-mechanical and physical-cellular properties based on renewable content and filler loading
• Capability to measure and validate abrasion behavior, durability, and other performance parameters for end-use suitability

Technology readiness level

The technology is currently at an early-to-mid development stage. Prior laboratory work at the host institution has demonstrated the ability to synthesize bio-based polyurethane foams with up to 100 percent renewable content and has established the relationship between filler content, renewable content, and the resulting physical, cellular, and thermo-mechanical properties. Preliminary studies have confirmed that varying renewable content shifts flexibility from semiflexible toward rigid structures, and that filler addition produces distinct cellular morphologies. Future validation will involve systematic formulation variation, abrasion testing, and commercial application assessment over an estimated ten-month development cycle.
