A method for applying a polymer coating to a substrate wherein the resultant layer of polymer on the substrate has a substantial thickness. A mixture of polymer material, including reactor bead polymer and ground polymer, may be used in a powder coating process to achieve thicker polymer layers. In separate embodiments, the resultant polymer layer may remain on the substrate or may be removed from the substrate.

The present invention provides a multilayer film which is provided with a vinylidene fluoride resin-containing layer that has less waviness, while having excellent tensile properties. A multilayer film which is obtained by superposing, on one surface of a layer B that contains a vinylidene fluoride resin, a layer A in a removable manner, said layer A being composed of a thermoplastic resin film that has a dimensional change rate of 5% or less in the MD direction and a dimensional change rate of 3% or less in the TD direction after being left at rest at 120° C. for 5 minutes as determined in accordance with JIS K7133 (1999). With respect to this multilayer film, the arithmetic mean height Sa.sub.1 of a 4.8 mm×3.7 mm region of a surface of the layer B after separation of the layer A, said surface having been in contact with the layer A, is 80 nm or less as measured by means of a non-contact interferometric microscope in accordance with ISO 25178-604; and the nominal tensile strain at break is 100% or more at 25° C. in both the MD direction and the TD direction if a tensile test is performed on the layer B after separation of the layer A in accordance with JIS K7127 (1999) (test piece type 2).

Provided is a resin film containing a polyvinylidene fluoride-based resin which is highly transparent and less likely to be cloudy even when it is heated and cooled. A resin film is composed of a resin composition containing 50 to 80 parts by mass of a polyvinylidene fluoride-based resin and 20 to 50 parts by mass of a polymethacrylic acid ester-based resin with respect to a total of 100 parts by mass of the polyvinylidene fluoride-based resin and the polymethacrylic acid ester-based resin, wherein a crystallinity of the resin composition is 15% to 35%; a ratio of α-type crystal to a total mass of α-type crystal and β-type crystal in the resin composition is 0 to 15% by mass; an average thickness of the resin film is 5 to 200 μm; and a HAZE measured according to JIS K7136: 2000 of the resin film is 20% or less.

A system and process for producing a homogenous extrudate powder coating composition having predetermined properties, the system comprising a color library database that is configured to store one or more input formulation data objects capable of use in controlling the inputs and operation of an electronically controlled homogenous extrudate mixer.

Described is a method for manufacturing a diaphragm assembly through the use of injection molding. The method can avoid the use of PTFE as a chemically resistant coating. Further, the method can increase overall adherence of a polymer diaphragm to an insert through the use of an interference surface on at least the surface of a head of the insert.

In an aspect, a biaxially oriented pipe has a thickened end portion. The end portion has the same inner diameter as the biaxially oriented pipe and has a larger thickness than the biaxially oriented pipe. The end portion is made of the same thermoplastic polymer composition as the biaxially oriented pipe.
