A pipe insulation product including a core of insulating material and a laminate surrounding the core and bonded to the core. The core may include an outer surface; an inner surface; and a wall extending between the outer and inner surfaces. The laminate may include a foil or metallized polymeric film sheet, a scrim, a porous media sheet, and a polymeric film sheet bonded together via an adhesive. The laminate may include a closure flap that is configured to adhesively seal opposite ends of the laminate together to form a cylindrical tube with the core enclosed therein. The closure flap may be configured to include a curl that provides a greater closure flap adhesive seal.

According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.

System for producing a fully impregnated thermoplastic prepreg

According to one embodiment, a system for manufacturing a polymethyl methacrylate (PMMA) prepreg includes a mechanism for continuously moving a fabric or mat and a resin application component that applies a methyl methacrylate (MMA) resin to the fabric or mat. The system also includes a press mechanism that presses the fabric or mat during the continuous movement subsequent to the application of the MMA resin to ensure that the MMA resin fully saturates the fabric or mat. The system further includes a curing oven through which the fabric or mat is continuously moved. The curing oven is maintained at a temperature of between 40&#xb0; C. and 100&#xb0; C. to polymerize the MMA resin and thereby form PMMA so that upon exiting the curing oven, the fabric or mat is fully impregnated with PMMA.

Fiber-containing polymethyl methacrylate (PMMA) prepregs are described that include a first and second plurality of fibers. The second plurality of fibers is made from a different material than the first plurality of fibers. The PMMA prepregs also contain a polymerized resin that includes polymethyl methacrylate that has been formed from a reactive resin composition that includes methyl methacrylate. Methods of making fiber-containing PMMA prepregs are also described.

A composition includes glass fibers and a polyether antistatic agent. The polyether antistatic agent has a molecular weight of less than about 2000, or less than about 1000. Exemplary polyether antistatic agents include polyethylene glycol, polypropylene glycol, a glycerol polyether, and combinations thereof. The polyether antistatic agent has a viscosity of less than about 600 cSt at 75&#xb0; F., or less than about 200 cSt at 75&#xb0; F. The composition may further include a solvent for the polyether antistatic agent; the solvent may include one or more organic soluble electrolytes, water or a combination thereof. Exemplary organic soluble electrolytes include calcium acetate, lithium acetate, an amine acetate, sodium benzoate, and combinations thereof. The composition may be used in various insulation applications, including in an insulation batt, insulation roll, insulation board, insulation pipe or unbonded glass fiber insulation. Methods for making glass fibers for use in insulation and methods for installing unbonded glass fiber insulation are also described.
