INTERCEPTION DEVICE MADE FROM THERMOPLASTIC POLYURETHANE

摘要

The invention relates to an interception device for moving articles or persons based on thermoplastic polyurethane which is obtained via the reaction in each case of at least one of the following starting materials: (a) diisocyanate, (b) compound which is reactive toward isocyanate and which has a number-average molar mass (Mw) of from 0.500×103 g/mol to 10×103 g/mol, (c) chain extender which has a molar mass of from 50 g/mol to 499 g/mol, and also optionally (d) with use of catalyst, of conventional auxiliaries and/or (f) of additives, where the interception device comprises a foil or a network made of the thermoplastic polyurethane and retention devices between which the foil or the network has been stretched flat, and the thermoplastic polyurethane is transparent. The invention further relates to the use of thermoplastic urethane for producing interception devices, and to a production process for an interception device made of thermoplastic polyurethane.

主权项

1. An interception device adapted for intercepting articles or persons, which interception device comprises at least one of a foil and a network comprising a transparent thermoplastic polyurethane and a retention device between which the foil and/or the network has been stretched flat, wherein the thermoplastic polyurethane is obtained by reaction of the following starting materials:
(a) an isocyanate (b) a compound which is reactive toward isocyanate and which has a number-average molar mass (Mn) of from 500 g/mol to 10×103 g/mol, and (c) a chain extender which has a molar mass of from 50 g/mol to 499 g/mol, and optionally with: (d) a catalyst (e) an auxiliary, and/or (f) an additive.
