Exemplary uses of polymeric foam layers described herein including a finishing pad for silicon wafers and vibration damping.

A method includes injection molding a preform using a two phase injection system having a first phase in which a material is injected into the preform and a second phase in which the material is injected into the preform. The preform is disposed in a mold. The preform is blow molded into an intermediate article. The intermediate article is trimmed to form a finished container. The first phase includes injecting a material into the preform to form a single layer of the preform and the second phase includes injecting the material to form inner and outer layers and an intermediate layer between the inner and outer layers. The inner and outer layers include the material and the intermediate layer includes at least one additive. Finished containers are disclosed.

A method for the crystallization of a film made of a thermoplastic film material, in particular a CPET material, to form a product in which a crystallization process is initiated by shaping the thermoplastic film material within a molding tool. A main crystallization of the crystallization process is carried on outside of the molding tool.

A method of manufacturing a semi-crystalline article from at least one pseudo-amorphous polymer including a poly aryl ether ketone, such as PEKK, including a softening step, wherein the at least one pseudo-amorphous polymer is heated to a temperature above its glass transition temperature to soften the polymer, and a crystallization step, wherein the at least one pseudo-amorphous polymer is heated to a temperature between its glass transition temperature and melting temperature, the pseudo-amorphous polymer being placed on a mold during either the softening step or the crystallization step before at least some crystallization takes place. The method results in articles demonstrating increased opacity, increased crystallinity, increased thermal resistance, improved chemical resistance, and improved mechanical properties over articles formed by traditional thermoforming processes.

Aspects of the disclosure relate to methods for making large areas of high aspect ratio micro or nanostructured foil using existing extrusion coating equipment. A method is disclosed for producing a high aspect ratio micro- or nanostructured thermoplastic polymer foil, or a nanostructured thermoplastic polymer coating on a carrier foil, comprising at least one high aspect ratio nanostructured surface area. The method comprises applying a high aspect ratio nanostructured surface on an extrusion coating roller and maintaining the temperature of the roller below the solidification temperature of the thermoplastic material. A thermoplastic foil and a thermoplastic coating made by the method is also disclosed.

Coextruded biaxially oriented sealable polyester films having at least one heat-sealable layer and at least one base layer. The heat-sealable layer has a sealing temperature on APET or PETG trays of at least 250 F. (121 C.) for seal strength of at least 1,500 g/in of film width, and a static and dynamic coefficient of friction of 0.28 or less. The heat-sealable layer includes one or more amorphous polyesters and one low melting point crystallizable polyester, such as polybutylene terephthalate (PBT).

The invention relates to a process for preparing a biaxially oriented multilayered film, the film comprising at least one layer comprising a polyolefin composition and at least one layer comprising a polyamide composition, the process comprising the steps of: a) Melting a polyamide composition comprising: i. a semi-crystalline polyamide Y comprising: monomeric units derived from caprolactam in an amount of at least 75 wt %; monomeric units derived from an aliphatic diamine in an amount of between 2.5 and 12.5 wt %; monomeric units derived from an aromatic diacid in an amount of between 2.5 and 12.5 wt %; wherein the weight percentage is given with respect to the total weight of the polyamide Y; ii. an amorphous polyamide in an amount of between 2.5 and 50 wt % with respect to the total weight of the polyamide composition; wherein the amorphous polyamide comprises: monomeric units derived from an aliphatic diamine X in an amount of between 30 and 70 wt %; monomeric units derived from an aromatic diacid in an amount of between 30 and 70 wt %; wherein the weight percentage is given with respect to the total weight of the amorphous polyamide; b) Melting a composition comprising a polyolefin; c) Co-extruding at least the melts obtained from a) and b) to form a film of at least two layers; d) Cooling the film to a temperature of at most 50 C., while the film is transported in a direction, referred to as machine direction; e) Stretching the film obtained in step d) with a stretch ratio of at least 13, at a temperature between the Tg of polyamide Y and Tm of the polyolefin, wherein the stretch ratio is defined as being the product of the stretch ratio parallel to the machine direction and the stretch ratio perpendicular to the machine direction.

Methods for producing spatial objects are disclosed. The methods generally include printing a spatial object, in an amorphous phase, using a three-dimensional (3D) printer and a printing material that consists essentially of polyaryletherketones. The methods further entail placing the spatial object in a container and submerging the spatial object in a suitable charging material. Next, vibrations are applied to the container that includes the spatial object and charging material. The container, charging material, and spatial object are then heated until the spatial object transitions into a semi-crystalline phase (at which point the spatial object can be removed from the container and charging material).
