Latest Patents
Marsh's latest patents focus on an injection molding process that utilizes reactive gas treatment. The first patent describes a method for creating shaped articles by injecting a thermoplastic or thermoset polymer into a mold cavity. This process is conducted in a reactive atmosphere containing between 0.1 mole % and 50 mole % of fluorine gas (F₂) and at least 20 ppm of oxygen (O₂) while the polymer is injected. The design ensures that any portion of the polymer contacts the reactive atmosphere for no longer than 0.5 seconds. The second patent reiterates this process, emphasizing the resulting shaped articles' altered physical and chemical characteristics. Notably, a weld line formed where two polymer interfaces meet serves as a clean break point when pressure is applied to the finished article. Additionally, the atmosphere in the mold cavity may contain sulfur trioxide (SO₃).
