R&D Scientist – Silicone Surfactants & PIR Foam
BS-level R&D / Research roles on Crosslinked list a median of $126k (444 that show pay). This posting does not list pay.
Synthesize silicone surfactants via hydrosilylation and test them in high-index PIR rigid foam formulations.
Worth knowing
Why it is interesting. Own both synthesis and foam application testing, correlating siloxane structure to insulation performance.
Might not be for you. Requires relocation to Chicago and hands-on work with hazardous chemicals.

Role details
THIS JOB REQUIRES RELOCATION TO CHICAGO. RELOCATION ASSISTANCE IS PROVIDED.
We are seeking a hands-on
R&D Scientist
to support the synthesis and application testing of novel
silicone surfactants for polyisocyanurate (PIR) rigid foams
.
In this bench-level chemistry role, you will work on both sides of product development: synthesizing siloxane polyether additives in the lab via
hydrosilylation
and evaluating their performance directly inside
high-index PIR rigid foam formulations
. You will optimize molecular structures (siloxane backbone length, EO/PO alkoxylation ratios) based on physical foam performance, cell structure, and insulation value.
Key Responsibilities
- Surfactant Synthesis:
Perform benchtop synthesis of organo-modified silicones, silicone polyethers, and polyether-modified siloxanes using
hydrosilylation reaction chemistry
.
- PIR Foam Formulation:
Prepare, pour, and test high-index
polyisocyanurate (PIR) rigid foam formulations
(NCO index > 200) using pentane, HFO, and water blowing agent systems.
- Property & Performance Testing:
Measure how custom silicone additives impact foam processing and physical properties, including:
- Reactivity profiles (cream, gel, tack-free, and rise times).
- Cell morphology (cell size analysis via microscopy, closed cell content).
- Thermal and mechanical metrics ($k$-factor / R-value, compressive strength, density).
- Structure-Property Correlation:
Analyze test data to establish how molecular changes in the silicone surfactant affect foam cell stabilization and nucleation.
- Process Scale-Up Support:
Assist senior team members and process engineering in transferring lab-scale organosilicone reaction protocols to pilot autoclaves and production reactors.
Qualifications
- Education:
B.S. (3+ years experience), M.S. (2+ years experience), or Ph.D. in Polymer Chemistry, Organic Chemistry, Chemical Engineering, or Materials Science.
- Core Technical Skills:
- Synthetic Experience:
Hands-on experience executing
hydrosilylation reactions
(Si-H siloxanes + allyl polyethers/alkoxylates) or organosilicone modifications.
- Formulation Experience:
Direct experience formulating and pouring
rigid polyurethane or high-index PIR foams
.
- Analytical Skills:
Proficiency with basic lab characterization tools (FTIR, NMR, viscometry, thermal conductivity $k$-factor testing, cell size microscopy).
