In some embodiments, the average dispersion of the wood pulp fibers within the thermoplastic polymer is equal to or greater than 90% as determined by the Dispersion Test. In some embodiments, the dilution level for detection in a bag at 40 C. is equal to or less than 450 as determined by ASTM E679. In some embodiments, the composition further includes 0.5 to 5 weight percent of an additive, such as a compatibilizer, a coupling agent, an anti-oxidant, and/or a lubricant. In some embodiments, the wood pulp fiber is bleached chemical wood pulp fiber.

The present invention relates to a process for the insertion and conveying of a labile additive, or a mixture thereof, in a transporting pipe, in which a main stream of molten material flows, said process characterized in that it incorporates said additive, or said mixture, in a portion of the pipe delimited by the main stream, according to one of the following alternative modes: a) in a longitudinal direction with respect to the flow direction of the main stream of molten material, or b) in a transversal direction with respect to the flow direction of the main stream of. molten material, or c) according to a composition of the longitudinal (a) and transversal (b) mode, thus forming a resulting stream which keeps the labile additives segregated from the main stream of molten material.

A length-adjustable adapter device (100) for connecting a plastics melt filtering device (200) to a pipeline (300), having at least a housing connection element (10) which has at least one inner flow duct (13) in a pipe extension (12) which is provided with an external thread (14), an adjusting ring element (20) having an internal thread (24) for receiving the external thread (14) of the pipe extension (12) and a line connection element (30) for connecting to the pipeline (300) with a line ring flange (31) and with a pipe extension (32) having an inner flow duct (33). The line ring flange (31) is rotatable in a receiving groove (23) of the adjusting ring element (20) and is fixed in a form-fitting manner against axially acting forces.

Techniques recycle plastics in multiple successive process steps. A polymer, preferably a recyclable material, is melted using a discharge extruder, filtered using a first filter device under a positive pressure atmosphere, filtered and degassed using a degassing device, and discharged using a discharge extruder. The degassing device has at least one filter element and a vacuum chamber with a negative pressure atmosphere for filtering and degassing purposes, wherein the plastic melt can be conducted into the negative pressure atmosphere of the vacuum chamber through the filter element.

The present invention is related to a process for bordering a corrugated plastic panel and to a panel obtained through that process. In particular, the invention is related to a process for making a corrugated plastic panel comprising a bordering made in-line or out-line in order to close the openings outwards. The invention is also related to an apparatus for bordering according to that process. The panel is sealed and shock resistant thanks to the laying of thermoplastic elastomeric material.

A flexible pipe body and methods of producing a flexible pipe body are disclosed. The method may include providing a tubular length of polymeric material for forming a polymeric layer of flexible pipe body; providing a strength layer radially outwards of the polymeric layer; and treating the polymeric layer with a non-ambient temperature and pressure.
