RFP Title


Highly Stretchable, Restorable, and Heat-resistant Film
RFP Description

NineSigma, representing a major materials manufacturer, seeks a partner to develop a film that has excellent stretchability and restorability under high-temperature condition as well as heat resistance. Given the difficulty of combining high stretchability and restorability with heat resistance in conventional technologies, we are looking particularly for suggestions on new polymer materials, composites, and laminate films, as well as performance improvement based on superior molding/forming techniques.


NineSigma's Client, a global materials manufacturer, develops and manufactures high-performance materials and films. In recent years, in a part of semiconductor applications, there is large demand for materials with outstanding stretchability, restorability, and heat-resistance. The Client is also engaged in the development of the target materials, however, the stretchability and restorability of a material is in trade off with its heat resistance, and the film that is sought after has yet to be developed. Meanwhile, the development of high-performance materials is important in a number of industrial fields such as automobile, aerospace, and medicine, which are the fields where technological breakthroughs are constantly necessary. The Client has therefore decided to make this RFP to further accelerate the development of their research and development endeavors.

Key Success Criteria

Film products to aim for

The Client seeks to develop a film that meets the following criteria:

  • Stretchability and restorability under high-temperature condition
    • Elongation: ≥800% at 170°C
    • Restorability: ≥90% at 170°C
  • Heat resistance
    • Does not deform for 10 minutes or longer when heated to 180°C with no pressure put on
  • Shape/size
    • A film with a thickness of 30–150 μm, width of approx. 1,500 mm, and length of approx. 1,000 m
  • Application: Semiconductors


Technology requirements

The Client seeks film materials or forming/molding technology that help meet the above-listed performance criteria

  • For film materials:
    • Single-resin materials
      • Elastomer with heat-resistant
    • Lamination of a highly flexible/restorable material and heat-resistant material
    • Composites containing fillers
      • Highly stretchable and restorable base resin materials
      • Fillers and additives that enhance heat resistance
  • For forming/molding technology
    • Optimization of temperature conditions during extrusion molding
    • Multilayer molding technology

It is not necessary for all requirements to be met at this point; proposals are welcome if there is a good chance of meeting them through further development within the next year or so. While it is preferable that a proposed material is already in the form of a film, proposals of fillers, additives or molding/forming techniques alone are also welcome.


Proposer requirements

  • Able to provide a few A4-sized sheets of film samples, or to undertake film molding/forming on commission
    • A few kg of samples will be required for a proposal on fillers or additives alone
Items to be Submitted

 Please include the following items in your proposal:

  • Proposed approaches (e.g., types of materials, forming methods)
  • Overview of proposed technology (characteristics, principle, uniqueness)
  • Development stage (verified at a lab level / under development for practical use / implemented for practical use)
  • Current performance
    • For film materials
      • Percentages of elongation and restorability in a high-temperature range (data for 120–180°C range preferable)
      • Level of heat resistance
      • Sizes and thicknesses
    • For molding/forming techniques
      • Types of materials the technique may be applied to
      • Film shapes/sizes available for molding/forming
      • Material properties with room for improvement (elongation, restoration, heat resistance)
  • Current challenges and future development plans/costs
  • Sample test conditions (quantity that can be provided, cost, period, contract terms)
  • Potential for scale-up
  • Past results (e.g. research papers, patents)


Notes on Response

Proposal shall have clear points and should not include confidential information. Supplemental files may be submitted in addition to the proposal.


Response evaluation

The client will evaluate all responses with the following criteria.

  • Overall scientific and technical merit
  • Approach to proof of concept or performance
  • Economic potential of concept
  • Realism of the proposed plan (action items, timeline, roles, deliverables, cost estimation)
  • Potential for proprietary position
  • Respondents’ capability and related experiences


Anticipated Project Process

After the submission due date, the client will review all submitted proposals. NineSigma will send the review results to each proposer 6-8 weeks after the due date. The client possibly asks clarifying questions before selecting the most suitable candidates for collaboration. The client will select best candidates through evaluations. During the selection process, the client may execute NDA with selected respondents, seek further information disclosure, and discuss specific development targets or potential opportunities.

The client will execute necessary agreements with the selected respondents and move to the advanced development phase. Specifics of any collaboration will be determined through consultation with the concerned parties.
