A method can be used to improve the quality of a foam, produced in a process for continuous production of foams using a surfactant with higher molecular weight as an additive in an aqueous polymer dispersion. The process involves foaming a mixture of the aqueous polymer dispersion and the surfactant, and the mixture is mixed in a foaming machine with a mixing head line speed of less than 4 m/s. The process additionally involves mixing the foam obtained from the foaming machine in an auxiliary inline mixer connected to the foaming machine, at a mixing head line speed of 5?50 m/s. A process for continuous production of foams and a continuous production line are also provided.

A method for producing low density polyester foam utilizing low I.V. polyester feedstock includes providing a low intrinsic viscosity raw material. The low intrinsic viscosity raw material includes between 25% to 100% of a post consumer polyester and has an intrinsic viscosity of less than 0.8 dl/g. The intrinsic viscosity of the low intrinsic viscosity raw material is increased via a de-condensation reaction configured to support foaming. The intrinsic viscosity of the low intrinsic viscosity raw material is increased to 1.1 dl/g or greater. A starting formulation is created including the low intrinsic viscosity raw material with the increased intrinsic viscosity. The starting formulation is foamed to create the polyester foam. Wherein, the polyester foam produced has a specific gravity of less than 0.65 g/cc.

A novel modified treated porous polyethylene membrane is imbibed with a hydrophilic polymer and heat treated to form a film having improved hand and noise. The films are useful to produce articles, especially textile laminates that can form waterproof breathable apparel.

The present invention relates to a soundproof tyre for vehicle wheels comprising a noise reducing element made by vulcanising a vulcanisable and expandable elastomeric compound comprising at least one elastomeric polymer, at least one expanding agent, and at least one compound selected from the group of (i) fatty acid amides and (ii) polymers and copolymers of caprolactone, lactic acid, glycolic acid, and mixtures thereof.

Embodiments relate to a polyester film, preparation method thereof and method for reproducing polyethyleneterephthalate (PET) container using same, the crystallization temperature (Tc) of the polyester film is not measured or is 70? C. to 130? C., as measured by differential scanning calorimetry, whereby it is possible to easily control the crystallinity. Accordingly, the polyester film has excellent shrinkage characteristics and recyclability, and clumping rarely occurs even if it is dried at high temperatures for a long period of time in the regeneration process.

A foam article, such as a cushioning element for an article of footwear, apparel or sporting equipment is provided that comprises a foam component, such as a midsole, having a number of beneficial physical characteristics. The cushioning element is a low-density foamed component with a surface skin that encases the remaining foam volume. The cushioning element has a number of foam volumes, arranged to achieve a more consistent foam component. Additionally, the cushioning element includes a series of concentric ridges extending radially outwardly from injection gate vestige locations, and a number of striation bands near the perimeter of the cushioning element. The location of the gate vestiges can be beneficially arranged to produce intersecting flow boundaries that are located away from key strain areas of the cushioning element. The cushioning element is more environmentally-friendly, requiring less energy to produce while still providing acceptable energy return and low density.
