Latest Patents

Hall's most recent innovations focus on enhancing the continuous process for the expansion of thermoplastic materials. His latest patents include:

1. **Apparatus for the Continuous Process for Expanding Thermoplastic**

This invention pertains to an apparatus designed for the continuous expansion of thermoplastic minipellets, particularly polypropylene. The apparatus features a mixing means that combines thermoplastic minipellets in water to form a slurry. This slurry is then connected to a pressurizing means for generating a flow of pressurized slurry, which is directed to a junction that entrains a blowing agent. The final step involves connecting the mixture to a heating means to elevate the temperature, resulting in expanded thermoplastic minipellets in an expansion vessel.

2. **Continuous Process for Expanding Thermoplastic Minipellets**

This patent addresses a continuous method for expanding thermoplastic minipellets, especially polypropylene. The process begins with the continuous charging and mixing of water and minipellets within a slurry tank to create a mixture that is pressurized. A blowing agent, such as butane, is incorporated into the pressurized slurry, followed by heating using a shell and tube heat exchanger to reach the softening point of the minipellets. After sufficient time for impregnation, the heated minipellets are released through orifices into an expansion vessel where the blowing agent evaporates, causing the minipellets to expand.
