RFP Title
Improving Elastomeric Adhesion Under High Thermomechanical Stress
RFP Description

NineSigma, representing a Global Supplier of Industrial Elastomer Products, invites proposals for technologies that will strengthen the bonding integrity at elastomer-to-elastomer and/or elastomer-to-fabric interfaces.

Background

Both flexible and rigid composites across the industrial landscape (rubber, PVC, other thermoplastics, etc.) employ a range of traditional bonding techniques to join layers of dissimilar elastomeric materials. NineSigma’s client employs a multi-ply system of engineered rubber, fabric / fiber reinforcements, and adhesive coatings to optimize bonding potential. However, thermal failure modes during operation can cause the various layers to unacceptably separate at high temperature (>400F).

Each individual layer in the structure represents a separate potential failure point. As such, the client seeks to identify technology solutions that can improve adhesion at any or all of these interfaces under high thermal stress. Additionally, proposals that would enable a reduction in the overall number of layers / interfaces by eliminating or reducing the need for coatings, adhesives or integrated fabrics are of significant interest.
 

Anticipated Project Phases or Project Plan

Phase 1 – Proof of concept

 

Phase 2 – To be determined based on scope and maturity of the proposed solution

 

Criteria for Moving from Phase 1 to Phase 2

  • Proof of technical concept against client’s specifications
    • Technical report
    • Performance against strip adhesion standards
    • Samples
    • Ability to produce material at volume
  • Plan for prototyping / commercial scale-up
  • Cost analysis

 

Key Success Criteria

The successful technology will:

  • Create a long-lasting bond
  • Improve bonding at one or more of the following interfaces:
    • Direct rubber to rubber interface (ideal)
    • Rubber to uncoated fiber/fabric interface
      • e.g. polyester, nylon, aramid, etc.
    • Rubber to coating or coated fabric interface
    • e.g. coatings, adhesives, resins, etc.
    • Fiber to coating interface
  • Maintain bond integrity under high thermomechanical stress
  • Adhesion: 50 lb/inch
  • Operating Temperature: Range in operation is typically 400F to >700F
  • Maintain adhesion after heat aging at elevated temperatures for extended time periods.
  • Withstand continuous temperature cycling without fluctuation or failure in bond integrity.

 

 

Possible Approaches

Possible approaches might include, but are not limited to:

  • Cross-industrial technologies and materials
  • Elastomer technology (formulations or additives) that would improve adhesion levels
  • Other elastomer additives that are adaptable to rubber
  • Novel adhesives, coatings, or surface treatments
  • Encapsulations or nanotechnologies
  • Improved fabrics or fiber technologies
  • Technologies to enhance the bonding affinity of coatings to fabric
  • Solutions that enhance bonding at high temperature
  • Computational solutions supported by material science and testing capabilities

 

Approaches not of interest

The following approaches are not of interest:

  • Solutions that cannot be adapted for compatibility with rubber substrates
  • Solutions not viable at elevated temperatures
