RFP Title
Insulating Material that Realize Ultra-Low Dielectric Loss
RFP Description

NineSigma, representing a major material manufacturer, seeks an organic insulating material (A) or inorganic insulating filler (B) that can achieve ultra-low dielectric loss in a high-frequency circuit (10 GHz or more).


As information-telecommunication systems realize faster speed and increased capacity, in electronic substrates, dielectric loss at high-frequency signals has become a challenge to achieve high-quality telecommunications and energy saving. To solve this problem, an insulating material with low dissipation factor and low dielectric constant needs to be developed. However, as a high-frequency region of 10 GHz or more will be used in the 5th generation mobile networks, the demand for the further improvement of the dielectric properties has become higher.


While the client has developed relevant technologies, various development activities are conducted around the world to meet increasing needs for the realization of the insulating materials with low dielectric loss. Therefore, the client has issued this open request to seek proposals for a material or technology that can address the above problem, in order to further accelerate R&D internally.

Key Success Criteria

Requirements for the insulating material

The client seeks an insulating material (A) or (B) below.



  • Target frequency: 10 GHz or more
  • Anticipated thickness of dielectric: Approximately 20 to 30 μm

A: Single body of organic resign material or resin-based composite

  • In case of a single body of organic resin: The dissipation factor should be less than 0.01 and/or the dielectric constant should be 3.0 or less (@10GHz).
  • In case of a resin-based composite: The dissipation factor should be 0.005 or less and/or the dielectric constant should be 3.0 or less (@10GHz).
      Note: It is preferable that both requirements for dissipation factor and dielectric constant are fulfilled; however, a material fulfilling either one is also welcomed.
  • A thermosetting resin-based material are especially welcomed.
  • Preferably, the material is highly adhesive to metal.

B: Inorganic filler material

  • The dissipation factor and dielectric constant should be 0.002 or less and 3.2 or less, respectively (@10GHz).
  • Size: Average diameter of approximately 3 μm or less
  • Shape: Preferably spherical
  • Thermal expansion coefficient: Preferably about the same as silica

Proposals not meeting requirements at present are also welcomed if they have the potential to achieve the expected performance with 1-2 years of additional development.


Requirements of the respondent

  • Be able to provide a small volume of sample (approximately 100 g to 1 kg).
  • It is preferable that a prototype can be developed at a level of several tens of kg by the respondent or within the client's network within 2 to 3 years.


Possible Approaches

Possible approaches might include, but are not limited to:

  • Organic resin material
    • Imparting a functional group
    • Modifying a skeletal structure
    • Addition of filler material
  • Inorganic insulating filler material
    • Silica-based filler
    • Filler using boron nitride and nano-carbon
    • Hybrid filler and other new materials
    • Making the filler material porous


Approaches not of interest

The following approaches are not of interest:

  • Concept-level material


Preferred Collaboration types
  • Joint Development
  • Contract Research
  • Technology Licensing
  • Supply Agreement
Items to be submitted

Responses should use the Proposal Template which is linked to the “attachments“ shown at the bottom of this page and include the following items:


  • Overview of the technology (characteristics, principle)
  • Type of the proposed material (organic resin/composite/inorganic filler)
  • Uniqueness of the technology
  • Development stage (performance verified on a lab scale/prototype already developed/already commercialized)
  • Current performance
    • Dielectric properties (dielectric constant, dissipation factor) and frequency at the measurement
    • (In case of an inorganic filler material) Shape and average size
  • Current challenges and future plans
  • Conditions for sample test (sample volume, cost, terms of agreement, etc.)
  • Potential of scaling up

Anticipated Project Phases or Project Plan

The client will review submitted proposals and possibly ask clarifying questions before selecting the most suitable candidates for collaboration. The client will select the best candidate(s) through evaluations. During the selection process, the client may execute non-disclosure agreements (NDA) with selected respondent(s), seek further information disclosure, and discuss specific development targets or potential opportunities.

The client will execute necessary agreement(s) with the selected respondent(s) and move to the advanced development phase. Specifics of any collaboration will be determined through consultation with the concerned parties.
