摘要： A large concentric co-extrusion die (1) is described having a plurality of annular or conical die mandrel layers (201-205). Each layer is formed between a pair of adjacent annular or conical die mandrels (101-106) defining between them a flow path for molten thermoplastics material from an inlet to an annular extrusion outlet (110) through which a thermoplastics tubular extrusion is formed in use. Extrusion takes place through the multiple annular layer outlets (301-305) to form a multi-layered product. At least one layer (203) of the annular or conical die mandrels has a plurality of molten material inlets arranged around the external circumference of the co-extrusion die with each inlet being connected to a feed channel (403) which has plural bifurcations (403.1, 403.2, 403.3) providing 2n subsidiary outlet feed channels (503) where n is the number of bifurcations. Each subsidiary outlet feed channel being connected to a corresponding helical outlet channel (703).
摘要翻译：描述了具有多个环形或圆锥形模心层层（201-205）的大型同心共挤出模头（1）。每个层形成在一对相邻的环形或圆锥形模心轴（101-106）之间，在它们之间形成用于从入口到环形挤出出口（110）的熔融热塑性材料的流动通道，在其中形成热塑性管状挤出物。通过多个环形层出口（301-305）进行挤出以形成多层产品。环形或圆锥形模芯心轴的至少一层（203）具有围绕共挤出模头的外圆周布置的多个熔融材料入口，每个入口连接到具有多个分支（403.1）的进料通道（403），403.2,403.3），其提供2n个辅助出口馈送通道（503），其中n是分叉数。每个辅助出口进料通道连接到相应的螺旋出口通道（703）。

摘要： The present invention provides a multilayered polymeric film with a luminous transmittance greater than 30% when measured using ASTM-D 1003-92, for covering an agricultural structure or greenhouse, wherein the film contains adjacent layers that have an average delamination strength of less than 250 g/15 mm when measured using ASTM D-1876. More particularly, the film is thus separated into two or more film layers which are inflated with gas to provide thermal insulation.
