- 27 years of experience in world-class Industrial R&D and Technical Service.

- Client-focused, service-driven, goal-oriented with solid personal and professional integrity always looking to deliver results that exceed expectations.

 

- Experience including (but not limited to) …

+ Diagnostic and definition of problem to be solved or the need to be met (whether related to Quality, Productivity or HSE)

 

Suspension-polymerization recipe optimization (types, quantities, procedures):

* Antifouling agents
* Primary and Secondary suspending agents
* Free-radical Initiators
* pH-control agent
* Antifoaming agent

* Short-stopper (normal and emergency)

 

+ Suspension-polymerization process optimization

* Charge procedure (sequential or simultaneous)
* Polymerization Stirring (constant or profile)
* Polymerization Temperature (constant or profile)
* Reflux condenser (startup and optimization)

 

+ Design and evaluation of trials at different reactor scales:

(Lab – 1 liter, Pilot plant – 1 to 250 gal, Commercial – 10 to 120 cubic meters)

+ Scaling-up and implementation of product / process improvements, including Risk-assessment and mitigation of undesirable effects

 

+ Prototyping and optimization of polymer materials:

* General Purpose PVC resins (pipe, flexible, injection)
* Specialty PVC resins (UHMW, Low Gloss, High Pipe Strength)
* CPVC resins (injection, extrusion)
* VC/acrylate block copolymers
* PVC nanocomposites

 

+ Lab analysis and characterization

* Thermal analysis (DSC, TGA)
* Microscopy (optical, SEM, TEM)
* Spectroscopy (IR, UV / Vis, 1H & 13C NMR)
* Mechanical (Instron) and Processing (torque rheometry)
* Other (MIP, CPA, DBT, sieving, Fish-eyes, XRD)

 

+ Vinyl polymers processability and compounding

* Thermal stabilization
* Plasticization
