A heat-shrinkable polyester film includes at least one polyester material made of at least one polyester forming composition which includes a dibasic carboxylic mixture and a diol mixture. The heat-shrinkable polyester film has a heat shrinkage rate of not lower than 25% in a shrinkage direction, which is measured by immersing the heat-shrinkable polyester film in hot water at 65° C. for 10 seconds. A method for producing the heat-shrinkable polyester film is also disclosed.

The present invention provides a protective coating for protecting a substrate from deleterious elements present in environments in which the substrates are deployed and methods and apparatus for deploying a PVC encasement with a longitudinal snap jacket of suitable length and girth to coat a pylon substrate or building girder and provide a filler within the snap jacket and around an encased pylon.

Particular embodiments of the invention include a closed-loop tread strip forming unit (100) and methods for forming tread strips using a closed-loop unit. Embodiments of such forming units include a tread strip extruder (110) located at a pre-cure end of the closed-loop tread strip forming unit. Such units include an uncured tread strip handling assembly (120) configured to transport the first uncured tread strip from the first tread strip extruder and to a first tread strip mold member (130). The unit further includes a curing press (150) having an inlet and an outlet, a pre-cure mold handling assembly (140) configured to insert the loaded tread strip mold member into the curing press, a post-cure mold handling assembly (160) configured to receive the loaded tread strip mold member from the outlet of the curing press, a return assembly (170) configured to transfer the first tread strip mold member to the pre-cure end to complete a closed-loop.

A weather strip including a bottom wall, a first lateral wall and a second lateral wall and in which an angle between the bottom wall and the first lateral wall is constant and an angle between the bottom wall and the second lateral wall is partially varied in a longitudinal direction is manufactured. The method includes: a first step of pre-forming the angle of the first lateral wall and the angle of the second lateral wall to be constant and equal to or larger than final maximum angles; a second step of regulating a boundary between the bottom wall and the second lateral wall from moving toward the first lateral wall by a regulating member; a third step of partially varying the angle of the second lateral wall by a movable roller; and a fourth step of forming the angle of the first lateral wall by a fine-movable roller.

An extruding unit, a forming roll unit and a thick portion forming mechanism are provided. The extruding unit has an ejecting slit which ejects sheet-shaped molten resin. The ejecting slit includes a standard gap portion and an enlarged gap portion. The standard gap portion is formed as a gap having a constant size. The enlarged gap portion is formed as a gap larger than the standard gap portion in a position corresponding to a thick portion. The thick portion forming mechanism forms one or several thick portions which are thicker than other portion, in the sheet-shaped molten resin continuously in the extrusion direction.

Methods making a metal-organic framework extrudate in an extruder comprising the steps of: (a) mixing a metal-organic framework material with an extrusion aid to form a metal-organic framework extrudate mixture; and (b) extruding the metal-organic framework mixture in the extruder to produce the metal-organic framework extrudate where the pressure within the extruder is reduced between about 10% to about 55% when compared to pressure within the extruder when extruding the metal-organic framework material without the extrusion aid. The extrusion aid can be a liquid extrusion aid, a solid extrusion aid and/or a polymeric extrusion aid.

A polymer body includes a first thermoplastic polymer, and a second thermoplastic polymer. The first thermoplastic polymer and the second thermoplastic polymer form a continuous solid structure. The first thermoplastic polymer forms an external supporting structure that at least partially envelops the second thermoplastic polymer. A first flow temperature of the first thermoplastic polymer is at least 10° C. higher than a second flow temperature of the second thermoplastic polymer. The first thermoplastic polymer may be removable by exposure to a selective solvent.
