Problems solved by technology

However, in most of these cases, the solution either ends up requiring more expensive equipment (such as advanced laminator equipment), or due to very strict process guidelines (such as fast curing EVA solutions for encapsulation layers) while very limited lamination process robustness

example 2

[0310] The polymers (a) according to the invention are prepared in a commercial high-pressure tubular reactor at a pressure of 2500 to 3000 bar and a maximum temperature of 250 to 300° C. using conventional peroxide initiators. Vinyl monomer, methyl acrylate (MA) polar comonomer and vinyltrimethoxysilane (VTMS) comonomer (silane group-containing comonomer (b)) were added to the reactor system in a conventional manner . It is well known to the skilled person that CTA is used to modulate MFR. In having the final polymer of the present invention ( a ) the desired balance of properties, the skilled person can control the process to obtain the polymer (a) of the invention.

[0311] The amount of vinyltrimethoxysilane units VTMS (comonomer containing silane groups), the amount of MA and the MFR are given in Table 1 2 .

[0312] The properties in the table below are measured from samples of polymer (a) obtained in the reactor or layers specified below.

Abstract

The present invention relates to a lamination process for the production of multilayer laminates comprising one or more substrate elements and one or more polymer layer elements, preferably for the production of photovoltaic (PV ) module lamination method, and relates to a PV module laminate.

Description

technical field [0001] The present invention relates to a lamination process for the production of multilayer laminates, preferably to a lamination process for the production of photovoltaic (PV) modules, and to PV module laminates. Background technique [0002] Lamination of polymer layers on rigid or flexible substrates of various materials is a well known technique and is used in many technical fields. The polymeric material used for the polymeric layer can vary depending on the end application of the article comprising the multilayer laminate. For example ethylene vinyl acetate (EVA) and other thermoplastic based polymers are commonly used layer materials in lamination processes. [0003] In general, the lamination of the layers to the substrate can be carried out, for example, by 1) so-called cast extrusion, wherein during the cast extrusion step at least part of the layers are produced on a prefabricated substrate or 2) by heat and pressure, The prefabricated substra...
