RFP Title


High-dielectric and Low-modulus Rubber
RFP Description

NineSigma, representing a large global manufacturer, seeks a partner for development a rubber/elastomer material with a high-dielectric constant and low-elastic modulus. The existing technology has difficulty in achieving a high-dielectric constant, low-elastic modulus and high moldability all at the same time. Accordingly, novel material modification techniques, additives, or polymer materials are welcome.

Key Success Criteria

Material requirements

  • Target base rubber materials: General polymers produced by the polymerization of monomers, supramolecular polymers through non-covalent binding, etc.
  • Applications: Applicable to actuators, sensors, etc.
  • Dielectric constant (at 20°C, 1 kHz): ε ≥ 16
    • Preferably ε = 32
  • Elastic modulus (tensile stress where the stretch is 1–5%): ≤2.5 MPa
  • Moldability (compatibility): Capable of maintaining compatibility with the base rubber material

Although the Client seeks a rubber/elastomer material that can meet the above-listed requirements, it is not necessary for all of them to be met at this point; proposals are welcome if there is a good chance of meeting them through another year or so of further development based on verified data.


Proposer requirements

  • Has technology that can meet the target physical property of dielectric constant and/or elastic modulus, and able to manufacture a sample material that fulfills the required properties by March 2020
  • Able to complete the data verification or conduct a small-scale sampling test by the end of July 2019
Possible Approaches

The Client expects technologies such as the following approaches, but is widely open to others:

  • Modification of polymer properties
  • Additives
    • Ceramic fillers
    • Metal fillers
    • Carbon fillers
    • Organic fillers
  • New polymer materials
  • Composite materials
Approaches not of Interest

The following approaches are not of interest:

  • Technology without verified data on all the required characteristics at present
  • Concept-level technology at present
Items to be Submitted


The Client is developing polymeric dielectric actuators towards practical use. For achieving the goal, it is necessary to balance a high-dielectric constant and low-elastic modulus in the polymeric material as well as to ensure moldability.

These properties, however, are in the relationship of trade-off, which interferes with the development of a material that can meet the above requirements. On the other hand, the realization of polymeric actuators has been expected in various industries, and relevant research and development have been promoted significantly. Under such circumstances, the Client has decided to invite proposals to accelerate technology development.


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.
