A method of reducing foamed density that results in a foamed polyvinyl chloride (PVC) component exhibiting reduced density. The foamed PVC component contains at least a PVC resin and a process aid blend. The process aid blend contains from 1 weight % to 60 weight % (based on the weight of the blend) of a functionalized process aid, and from 99 weight % to 40 weight % (based on the weight of the blend) of a non-functionalized process aid. The functionalized process aid includes at least one base polymer functionalized with a reactive epoxy, hydroxyl, β-keto ester, β-keto amide, or carboxylic acid functional group. The foamed PVC component containing the process aid blend has a lower density than a reference foamed PVC component made using the same process conditions and additives, but which contains only non-functionalized process aid and not the functionalized process aid.

A patterned surface structure formed from a ferrofluidic polymer resin having a plurality of magnetic nanoparticles. The polymer resin is patterned with a magnetic field that is applied to the ferrofluidic polymer resin during curing. The ferrofluidic polymer resin may be cast over a non-magnetic planar substrate. A magnetic field is applied to the ferrofluidic polymer resin to induce a pattern in a surface of the ferrofluidic polymer resin. The patterned ferrofluidic polymer resin is then cured to form the permanently patterned surface.

The disclosed latex system comprises a one-component, closed-cell, semi-foam, mastic sealant using gas-filled, flexible, organic microspheres to create a product that is elastic and compressible under pressure without protruding in an outward direction when compressed, thereby allowing the applied sealant to compress in an enclosed, maximum-filled channel unlike typical mastic sealants (while retaining the ability to rebound). This allows the sealant to function as a gasket, and, once fully cured, to have properties including vibration damping, insulating, and condensation resistance. The sealant can be formulated as an air barrier or a vapor barrier and at various degrees of moisture resistance. It may be applied by different packaging variations including aerosol can (bag in can or bag on valve), airless sprayer, cartridge tubes, foil tubes, squeeze tubes, and buckets to be applied using a brush, trowel, spatula, etc. The disclosed mastic sealant can also be formulated to be smoke-resistant and flame-resistant.
