PPI is actively involved in the development of high-performance foam products from industrial to pharmaceutical polymers, utilizing both chemical and physical blowing agents, such as CO2, N2, hydrocarbons, HCFCs, HFOs, NaHCO3 etc.

 

PPI’s foam production capabilities are:

Batch Foaming

PPI is capable of production of foam samples with various densities using chemical and physical blowing agents. Samples are loaded into a mold and placed between the plates of a Carver press kept at a specific temperature. The blowing agent is then introduced to the mold for a certain amount of time.  The gas pressure is then released rapidly. Due to the sudden pressure release and resulting thermodynamic instability of the polymer-gas system, cells are nucleated and a cellular structure is produced.

Extrusion Foaming

Various extrusion systems are available for production of low/medium/high density foams:

 

Expandable Beads and Mixing Technology

A sintering unit which consists of a steam generator and various molds is used to produce a variety of expanded foam products from expandable beads.  Seamless and complex geometries can be produced using this technique where no secondary process, such as thermoforming or welding will be required.
