Whenmaterials manufacturer, invites proposals for a transparent PET film (25μm to 200μm thick) isparticles with high affinity for PET for use in manufactured by biaxial stretching, the followingtransparent PET resins. The particles will be requirements must be met to create the preferredincorporated into PET films to create a slight characteristics (see Figure 1):surface roughness, in order to prevent  Particles create a slight roughness orblocking (films adhere to each other and do not irregularity on the top and bottom surfaces ofseparate easily). the film (2μm to 5 μm) (see Fig. 2). Particles may follow the biaxial stretching, but shouldThe client is particularly interested in new types of not follow completely or become too flattenedparticles that are compatible with PET and that (see Fig 3) to create the desired surfacemay have anti-blocking properties. Proposals for texture.innovative uses of traditional anti-blocking agentssuch as silicas or calcium carbonate also are ofinterest.Particle Requirements Fig. 2: View of particle arrangement  Particle diameters: 0.5μm to 4μm  The particles maintain continuous wetting of  Index of refraction: 1.5 to 1.7 PET resin, so that no voids (microscopic gaps around particles) form (see Fig. 3). Voids can lead to optical defects in the clear film.

NineSigma Request # 67713 Particles with High Affinity for PET Resins Page 3RESPONDING TO THIS REQUEST NON-CONFIDENTIAL DISCLOSURE By submitting a Response you represent that the Response does not and will not be deemed to contain any confidential information of any kind whatsoever. Your Response should be an executive summary (about 3 pages). The Response should briefly describe the technical approach and provide information on technology performance, background, and description of the responding team and their related experience. A Response Template is available from our website. By submitting a Response, you acknowledge that NineSigma’s client reserves the sole and absolute right and discretion to select for award all, some, or none of the Responses received for this announcement. NineSigma’s client also may choose to select only specific tasks within a proposal for award. NineSigmas client has the sole and absolute discretion to determine all award amounts. RESPONSE EVALUATION NineSigma’s client will evaluate the Response using the following criteria:  Overall scientific and technical merit of the proposed approach  Approach to proof of concept or performance  Potential for proprietary position (i.e., is the technology novel or protectable)  Economic potential of concept  Respondent’s capabilities and related experience  Realism of the proposed plan and cost estimates The client will contact respondents with highly responsive proposals for next steps.
