Übersetzung für "Embrittle" in Deutsch

The so-called "self-supporting films" of Shirakawa embrittle completely in the case of oxidative complexing.

The nitrogen is used to embrittle the fatty acid amides.

By exposure to ozone, these materials embrittle very rapidly.

The coating has a high elasticity and doesn t embrittle.

The coating has a high elasticity and doesn't embrittle.

One, therefore, obtains a long, wire-shaped structure such as is required for coils, without the occurence of reactions which would embrittle the conductor.

For this purpose, the elastic scrap rubber, with the aid of a cooling medium, namely liquid nitrogen, is cooled down to very low temperatures, approximately -140° C., causing it to embrittle, whereafter it can be ground.

A problem of the known process arises from having to cool and embrittle the scrap tires to be reduced right into the innermost region thereof.

With this process step, a good metallurgical bond is obtained between the wire cores and the matrix material surrounding them without the occurrence of reactions which would embrittle the conductor.

This can be important, for instance, because the neutron radiation, especially that of fast neutrons, can embrittle the material of the reactor pressure vessel which customarily encloses the core.

Besides coating agents containing unsaturated oils such as butadiene oil or tung oil as binder component give coatings which have a strong tendency to embrittle and are not weatherproof.

Thus, these additions lead to a marked interference in the thermosetting resin structure, are limited in their plasticizing effect at low temperatures, tend to exudate when exposed to heat and during aging, and embrittle the cured systems.

Biaxially oriented, coextruded polyester films with a base layer at least 90% by weight of which is composed of a thermoplastic polyester, preferably polyethylene terephthalate (PET), and with at least one sealable outer layer and a second nonsealable outer layer and, if desired, with other intermediate layers, and comprising at least one UV absorber, preferably hydroxybenzotriazoles and triazines, have high UV resistance, do not embrittle when exposed to high temperatures, have a surface without undesirable haze and are suitable for numerous indoor and outdoor applications.

In particular, during outdoor use over a period of some years, the films should not yellow, embrittle or show surface-cracking, nor exhibit any impairment of mechanical properties.

Tests have moreover shown that the film of the invention does not embrittle when exposed to temperatures above 100° C. for a prolonged period.

In particular, an antioxidation coating based on gallium has the advantage that it does not significantly embrittle an underlying base material containing iron, cobalt or nickel.

The object of the present invention was to provide a transparent, flame-retardant, UV resistant, oriented film having a thickness of from 5 to 300 ?m which can be produced cost-effectively, can readily be oriented, and has good mechanical and optical properties, and above all is flame-retardant, and does not embrittle at high temperatures and has high UV resistance.

Measurements showed that the film of the invention does not embrittle over long periods at high temperatures of 100° C., a fact which is more than surprising.

It was therefore more than surprising that by using masterbatch technology and a suitable predrying and/or precrystallization procedure and, if desired, using small amounts of a hydrolysis stabilizer, it is possible to produce a flame-retardant, thermoformable film with the required property profile cost-effectively and especially without any caking in the dryer, and that on exposure to high temperature the film does not embrittle, and does not break when folded.
