Any chemical compound that, admixed with a thermoplastic resin, selectively absorbs ultraviolet rays; used to prevent ultraviolet degradation of polymers.  2, record 1, English, - ultraviolet%20stabilizer

Record number: 1, Textual support number: 1 CONT

When a polymer absorbs light, it may reradiate the absorbed energy at much longer wave lengths(heat), at slightly longer wave lengths(luminescence), or the energy may be transferred to another molecule. When none of these processes is operative, the absorbed light energy may cause bond breaking leading to degradation. By incorporating an ultraviolet absorbing compound into the plastic, it is possible to essentially eliminate all of the above processes, since the absorber even at concentrations as low as 0. 5% can effectively compete for the incident ultraviolet radiation, thus protecting the plastic form degradation. A second approach to stabilization is to incorporate an additive which, though not an absorber in itself, can accept energy from the polymer substrate, and thus, leave the polymer intact. Since protection of plastics against light degradation can be achieved by these two mechanisms, the broader term "ultraviolet stabilizer" or "light stabilizer" is used to refer to such additives.  1, record 1, English, - ultraviolet%20stabilizer

Produit chimique que l'on ajoute à un matériau macromoléculaire (matière plastique, élastomère, fibre) pour le protéger contre l'action dégradante des rayons ultraviolets.  2, record 1, French, - agent%20anti%2DUV

Record number: 1, Textual support number: 1 CONT

Le principe de l'agent anti-UV est d'absorber l'énergie reçue sans réémettre dans le visible. Les principaux produits utilisés sont la benzophénone et le benzotriazol. Il faut noter également que l'introduction de certains pigments (oxydes métalliques, noir de carbone) favorise la résistance aux UV de même que l'application d'un revêtement (peinture).  7, record 1, French, - agent%20anti%2DUV

Preshrinking of cotton or "heat setting" of synthetics may be necessary for dimensional stability. The effectiveness of heat setting depends on the original stabilization temperature used. If the synthetic fabric is later exposed to a significantly greater temperature, dimensional change can occur.  4, record 2, English, - heat%20setting

thermosetting: having the property of becoming permanently hard and rigid when heated or cured: capable of changing from a plastic or fusible state to an infusible or insoluble state by a chemical reaction affected by heat or other means and leading to a complex high polymer.  5, record 2, English, - heat%20setting

[La thermofixation] confère une stabilité dimensionnelle, à un tissu synthétique ou mélange, tout en lui apportant certaines propriétés telles qu'une résistance accrue aux plis et une meilleure résilience sous une charge ou une température élevée, cette fixation est appliquée par le biais d'une chaleur humide ou sèche.  3, record 2, French, - thermofixation

It is possible to produce uniforms with such protection specifically for wear in high temperature regions, but by their very nature protective suits are hot and uncomfortable for prolonged periods of wear due to the absorbent layers of activated charcoal granules or fibres that they incorporate. These granules and fibres act as a barrier to the escape of body heat which could, in extremes, lead to physical collapse due to heat exhaustion. This has given rise to proposals for liquid cooling or body temperature stabilization units supplying webs of cooling pipes worn close to the skin.  1, record 3, English, - body%20temperature%20stabilization%20unit

Il est possible de fabriquer des tenues de protection NBC spéciales pour pays chauds mais ces tenues sont pénibles à supporter pendant de longues périodes parce qu'elles contiennent des couches absorbantes de granulés de charbon actif et de fibres. Ces granulés et ces fibres empêchent la chaleur du corps de se dissiper, l'élévation de température interne qui en résulte pouvant conduire dans les cas extrêmes à la perte de connaissance par épuisement. Pour y porter remède, on a imaginé de refroidir ou de stabiliser la température interne au moyen d'un réseau de fines canalisations dans lesquelles circule un réfrigérant.  2, record 3, French, - unit%C3%A9%20de%20stabilisation%20de%20la%20temp%C3%A9rature%20interne
