Methods and systems for making a film made of dynamically vulcanized thermoplastic elastomeric material are provided herein. The subject methods and systems achieve dimensional stability of an elastic film by applying thermal treatment as part of the film making process and enhance the shrinkage of the film by intentionally with stretching the film while hot and freezing the film in the stretch. The systems and methods are useful in controlling shrinkage of DVA post film extrusion.

A thermoplastic elastomer contains (a) hard segments of a polyester and (b) soft segments containing repeating units derived from an aliphatic carbonate, wherein the thermoplastic elastomer exhibits a melt flow index (MFI) measured at 230 C. under a load of 10 kg (MFI 230 C./10 kg) according to ISO1133 (2011) of at most 40 g/10 min. The thermoplastic elastomer is produced by subjecting a precursor of the thermoplastic elastomer to solid state post reaction processing at a temperature between 140 and 170 C. until the thermoplastic elastomer has the required MFI of at most 40 g/10 min measured at 230 C. under a load of 10 kg (MFI 230 C./10 kg) according to ISO1133 (2011).

A method for the production control of an extruded plastic product with the following steps: recording at a first measuring point a first actual temperature of a measuring area provided on the plastic product, recording a second actual temperature of the measuring area at a second measuring point which is arranged at a distance from the first measuring point in a direction of extrusion of the plastic product, determining a setpoint temperature of the measuring area at the second measuring point, and outputting information on whether the second actual temperature is inside or outside a prescribed tolerance range of the setpoint temperature.

A manufacturing process for filler tube includes: a workpiece arrangement step of arranging a workpiece onto an outer peripheral mold not only to axially lock a to-be-locked portion with respect to a locking portion but also so as to make the outer peripheral mold, which is set at a predetermined temperature, support a cylinder-shaped body of the workpiece on the outer peripheral face; and a flare-molding step of flare molding a flange by inserting an inner peripheral mold, which is set at a higher temperature than the predetermined temperature of the outer peripheral mold, into a to-be-molded portion on the inner peripheral side, and by relatively moving the outer peripheral mold and the inner peripheral mold in the axial direction to make a counter-welding-face forming portion and a welding-face forming portion clamp the to-be-molded portion between them in the axial direction.

A copolymer of propylene with hexene-1 containing from 5 to 9% by weight of recurring units derived from hexene-1, having a melting temperature from 125 to 140 C. and Melt Flow Rate (ASTM D1238, 230/2.16 Kg) from 0.1 to 3 g/10 min., is used to produce blown films having valuable mechanical and optical properties.

The invention involves a system and method for constructing lawn furniture. The system includes box type beam members as well as a large box structure supported above a ground surface. The box structure provides rigidity and stability to the furniture while also functioning as storage space. The components are formed to ship in a dissembled compact state and snap together with minimal use of fasteners and tools.

The present invention relates to an external cooling system for a molten film tube produced by a blown film tubular extrusion process. Embodiments of the present disclosure provide a unidirectional cooling element having a unidirectional cooling interface containing a cooling gas deflector spaced adjacent to the molten film tube. The unidirectional cooling element operably expels cooling gas in a path with the flow of the molten film tube toward an exit gap formed between the unidirectional cooling interface and the molten film tube. The minimum gap between the unidirectional cooling interface and the molten film tube occurs at the exit gap, and advantageously, the unidirectional cooling interface is provided with one or more compound angles to maximize stability and cooling efficiency.

A tube arrangement for the transport of temperature control medium, comprising a base body (2) made of polymeric material and produced by means of blow molding, wherein at least one functional element (3) is arranged in the base body (2), which element is in operative connection with the temperature control medium.

A process for the production of a thermoplastic elastomer containing hard segments (a) of a polyester and soft segments (b) containing repeating units derived from an aliphatic carbonate, in which process a precursor thermoplastic elastomer is subjected to solid state post condensation at a temperature between 140 and 170 C. Also claimed is the thermoplastic elastomer.
