Abstract
A method of producing crosslinked reformed products provides such products which are, in one embodiment, produced by the monosil process and suitable for use in potable water applications. In a described embodiment, a method includes the steps of introducing a reduced level of silane in a feed throat of an extruder, extruding a product, reforming the extruded product, and then curing the reformed product for an extended period of time.
Claims4
A method of producing a crosslinked product, the method comprising the steps of:
- forming the product using the monosil process, wherein the forming step includes preparing a mixture of silane and a base resin within an extruder prior to melting the base resin in the extruder, and extruding the product from the extruder;
- and
- curing the product at an elevated temperature in the presence of water so that the product is at least approximately 60% crosslinked and so that the product has a maximum methanol extraction value of approximately 12.2.
A method of producing a crosslinked product, the method comprising the steps of:
- forming the product using the monosil process;
- and
- curing the product at an elevated temperature in the presence of water so that the product is at least approximately 60% crosslinked, so that the product has a maximum methanol extraction value of approximately 12.2, and wherein the curing step is performed for a minimum of approximately 8 hours.
