TLT Foamer Technology
The TLT-Foamer is a proprietary technology capable of generating microfoams (bubble sizes less than 100 micron diameter) without the use of environmentally harmful dissolved or liquefied gas propellants - foaming agents. Though originally developed to provide a more sustainable foam aerosol dispenser, the technology can be applied more widely in devices, appliances, and potentially processing applications.
In conventional foam aerosol products the microfoam structure is generated by a liquefied or dissolved gas (e.g. butane, propane, nitrous oxide) being present under pressure, and forming part of the liquid formulation. On dispensing product from the aerosol can the liquefied or dissolved gas experiences a sudden pressure drop , causing it to rapidly expand within the formulation. The role of the liquefied or dissolved gas as the foaming mechanism has proved to be a major hurdle in finding more sustainable alternatives for producing high quality microfoams from aerosols.
The TLT-Foamer technology works with sustainable gases such as compressed air and nitrogen. It uses a completely novel method of foam production that can be cheaply manufactured and implemented in a variety of applications. The technology does not rely on fine constrictions, meshes, or porous media to generate fine bubble structure. Instead our technology utilizes a specific flow path geometry, which iteratively reduces bubble size along its length.
General Features of the TLT Foamer
Utilizes environmentally friendly gases (air, nitrogen)
Requires a source of foamable liquid and a source of compressed gas (e.g. air, nitrogen)
Capable of generating a range of different foam textures with varying gas content (overrun)
Can be manufactured using low cost, high volume manufacturing methods such as injection molding
May be incorporated as a module within a powered device, as a component within an aerosol dispenser, functional packaging, or form part of a manufacturing process.
May be manufactured from a wide range of moldable or machinable materials including polymer materials, metals, glass, or ceramics
Capable of foaming complex foam formulations containing high loadings of particulates (suspensions) and emulsions
The TLT-Foamer technology is scalable allowing for dispensing requirement from a few centiliters to continuous industrial scale production (L/s) of microfoam
