Meaning
Enhanced evaporation methods use injected fluids to help pull out unwanted volatile components from a melt within a machine barrel. During stripping agent extrusion, substances like water or nitrogen are mixed thoroughly into the molten plastic to create a massive surface area where contaminants can shift from the polymer to the gas phase. It terminates once the melt leaves the final low-pressure zone.
Vapor Exchange
Interaction between the additive and the plastic speeds up the departure of lingering odors. Whenever stripping agent extrusion is implemented, the injected fluid expands rapidly into bubbles which then rupture as they exit the vent ports, taking chemicals with them. This cleaning action is much faster than vacuum alone.
Moisture Control
Selecting the right quantity of agent is necessary to avoid damaging the resin chains. If too much stripping agent extrusion takes place with water-based fluids in sensitive materials like polyester, the resin might undergo hydrolysis and lose its value. Controlled dosages ensure purity without degradation.
Purity Yield
Removing difficult-to-catch components results in a cleaner final product for demanding markets. Parts made from resin processed via stripping agent extrusion show lower levels of solvent residue, making them suitable for direct contact with neutral liquids like mineral water. This allows for higher virgin material substitution rates.
