Foam blowing agents subject to the regulation, Prohibitions on Use of Certain Hydrofluorocarbons in Stationary Refrigeration, Stationary Air-conditioning, and Other End-Uses (HFC Regulation).
Products containing foam are subject to prohibited refrigerants under Section 95374 Table 1 and Table 2. Products containing foam are also subject to prohibitions, exceptions, recordkeeping, and attestation requirements under Section 953575 (a) and prohibitions and exceptions under Section 953575 (b).
“Foam” means a product with a cellular structure formed via a foaming process in avariety of materials that undergo hardening via a chemical reaction or phase transition.
“Flexible Polyurethane” meansa non-rigidpolyurethane foam including, but not limited to, that used in furniture, bedding, chair cushions, and shoe soles.
“Integral Skin Polyurethane” means a self-skinning polyurethane foam, including but not limited to that used in car steering wheels and, dashboards.
“Phenolic Insulation Board and Bunstock” means phenolic insulation manufactured by a process in which a plastic foam forms an insulating core between two flexible tissue faced layers, or produced by mixing high solids and phenolic resin with a surface acting agent, including but not limited to that used for roofing and wall insulation. Bunstock or bun stock is a large solid box-like structure formed during the production of polystyrene insulation.
“Polyolefin” means foam sheets and tubes made of a macromolecule formed by the polymerization of olefin monomer units.
“Polystyrene Extruded Boardstock and Billet (XPS)” means a foam formed from polymers of styrene and produced on extruding machines in the form of foam slabs that can be cut and shaped into panels used for, but not limited to, roofing, walls, flooring, and pipes.
“Polystyrene Extruded Sheet” means polystyrene foam including that used for packaging, including but not limited to products made into food-service items, including hinged polystyrene containers (for "take-out" from restaurants); food trays (meat and poultry), plates, bowls, and retail egg containers.
“Polyurethane” means a polymer formed principally by the reaction of an isocyanate and a polyol. “Polyurethane” includes polyisocyanurate (“polyiso”).
“Rigid Polyurethane” means a rigid closed-cell foam made of polyurethane.
“Rigid Polyurethane Appliance Foam” means polyurethane foam used for insulation in domestic appliances.
“Rigid Polyurethane Commercial Refrigeration and Sandwich Panels” means polyurethane foam used for insulation in walls and doors, including that used for commercial refrigeration equipment, refrigerated transport trailers, and garage doors.
“Rigid Polyurethane High-pressure Two-component Spray Foam” means a liquid polyurethane foam system sold as two parts (i.e., A-side and B-side) in non-pressurized containers that is field or factory applied in situ using high-pressure proportioning pumps at 800-1600 pounds per square inch (psi) and an application gun to mix and dispense the chemical components.
“Rigid Polyurethane Laminated Boardstock and Polyisocyanurate Laminated Boardstock” means laminated board insulation made with polyurethane or polyisocyanurate foam, including but not limited to that used for roofing and walls.
“Rigid Polyurethane Low-pressure Two-component Spray Foam” means a liquid polyurethane foam system sold as two parts (i.e., A-side and B-side) in containers that are pressurized to less than 250 psi during manufacture of the system for application without pumps that is typically applied onsite relying upon a liquid blowing agent and/or gaseous foam blowing agent that also serves as a propellant.
“Rigid Polyurethane Marine Flotation Foam” means a buoyancy or flotation polyurethane foam used in boat and ship manufacturing for both structural and flotation purposes.
“Rigid Polyurethane One-component Foam Sealants” means a polyurethane foam generally packaged in aerosol cans that is applied in situ using a gaseous foam blowing agent that is also the propellant for the aerosol formulation.
“Rigid Polyurethane Slabstock and Other” means rigid polyurethane foam formed into slabstock insulation for panels and fabricated shapes for pipes and vessels.
