RFP Title


Preventing Airborne Particle Accumulation on PE-PP Membranes
RFP Description

NineSigma, representing a leading consumer goods manufacturer, invites proposals for solutions or technologies that repel dust or prevent the accumulation of dust particles on porous polyolefin fiber-based membranes.


NineSigma’s client, a leading consumer goods manufacturer, uses porous polyolefin-based membranes that prevent dust from traveling within an air stream. The membranes are made of polyethylene (PE) fibers or a mix of polyethylene (PE) and polypropylene (PP) fibers. One of the major drawbacks of these porous membranes is that dust particles tend to accumulate quickly on the outer side of the membrane, thereby affecting the airflow through the porous membrane. The increased resistance reduces the efficiency of the entire system and leads to increased maintenance requirements.

In order to improve the efficiency and the service life of the membrane, our client is looking for methods or technologies, chemical or physical, that reduce or prevent the accumulation of dust particles to the surface of the porous membrane.

The objective of this RFP is to find solutions that reduce or prevent the accumulation of dust on porous polyolefin-based membranes.

Key Success Criteria

The successful solution has to:

  • Reduce or prevent the accumulation of dust on porous polyolefin-based membranes
  • Be proven on lab scale
  • Be resistant to water at 40 °C
  • Be durable
  • Be safe for human contact

 After additional development, the solution has to:

  • Be scalable to industrial quantities
Possible Approaches

Possible approaches might include, but are not limited to:

  • Hydrophobic or oleophobic coatings
  • Anti-static coatings
  • Surface micro-structuring or nano-(composite) coatings
  • Anti-fouling/ anti-adherent coatings or surface treatment
  • Self-cleaning technologies
  • Oil-free Lubricious coatings
  • Other permanent chemical surface treatments
  • An additive for incorporation into coating formulations
  • Physical approaches that allow frequent removal of the adhered particles
Items to be Submitted

Appropriate responses will use the response form and address the following:

  • High level, non-confidential, description of proposed technology including:
    • Working principle or knowledge base to support your approach
    • Availability of technical data (supporting data as an attachment)
    • Technology maturity (concept, prototype, ready to commercialize, commercialized)
  • Pathway to industrial scale including timing, estimated budget, and capacity for manufacture
  • Position on intellectual property including patent references
  • Desired relationship with solution seeker
  • Team description and related experience

Only non-confidential information is requested and may be submitted.

Please contact Dr. Tom Vranken,, if you need assistance with submitting your proposal.
