BARRIER RESIN [10 records]

Record 1 2014-12-29

English

Subject field(s)
  • Plastic Materials
DEF

The property of a material by which a negligible portion of the transmitted light undergoes scattering, thereby enabling objects to be distinguished clearly through the material.

CONT

The advantage of the [stretch blow molding] process is an improvement in resin performance, such as bottle impact strength, cold strength, transparency, surface gloss, stiffness, and gas barrier, which permit lighter weight, lower cost bottles, use of lower cost resins with less impact modifiers, or products packaged that normally would not be suitable.

OBS

transparency: term and definition standardized by ISO.

French

Domaine(s)
  • Matières plastiques
DEF

Propriété d'un matériau de ne diffuser qu'une partie négligeable de la lumière transmise, permettant ainsi de distinguer clairement des objets à travers son épaisseur.

CONT

La transparence est essentiellement liée à la morphologie. L'existence d'une morphologie entraîne l'existence de domaines ayant des indices de réfraction différents, donc réfractant et diffusant la lumière. Le trajet optique des rayons lumineux est donc augmenté, et l'intensité des rayons émergents diminuée. Le matériau est donc translucide à opaque. Un polymère amorphe est transparent.

OBS

transparence : terme et définition normalisés par l'ISO.

Spanish

Campo(s) temático(s)
  • Materiales plásticos
DEF

Propiedad de un material por la cual una parte insignificante de la luz transmitida se difunde, permitiendo distinguir los objetos claramente a través del material.

Subject field(s)
  • Plastics Manufacturing
OBS

E. I. du Pont de Nemours & Co. has developed a novel approach to gain some of the advantages of a coextruded blow-molded bottle without the cost and complexity of multiple extruders and expensive scrap reclaim systems. Only minor modification of the basic equipment is required. A barrier resin is tailored for physical blending with a base resin in much the same way that colorant is blended with a resin. However, instead of producing a homogenized mix, the barrier resin is permitted to laminate in the base resin. Several random multiple layers of barrier resin of various lengths and sizes are created. Although no single layer completely covers the entire shape and surface of the bottle, barrier is created by the "tortuous path" the permeating gas must follow. A modified nylon material is the first to be used for this approach. Applications include fuel tanks and bottles for agricultural chemicals, thinners, and solvents.

Domaine(s)
  • Plasturgie
OBS

C'est pourquoi la résine barrière est placée en sandwich entre deux couches de polymère hydrophobe, c'est-à-dire qui repousse l'humidité.

OBS

[...] les couches fonctionnelles forment elles-mêmes une structure multicouche comprenant une couche de résine barrière emprisonnée entre deux couches de résine adhésive.

CONT

In these experiments, the moisture barrier was not as effective as the shrinkage measurements, because there was no aluminium foil between the two coats of resin.

Dans ces expériences, la barrière d'humidité n'était pas aussi efficace que dans les mesures de retrait, faute d'une feuille d'aluminium interposée entre les deux couches de résine.

CONT

Unplasticized PVC presents some processing difficulties due to its high melt viscosity; in addition, the finished product is too brittle for some applications. To overcome these problems and to produce toughening, certain polymeric additives are usually added to the PVC. These materials, known as impact modifiers, are generally semicompatible and often somewhat rubbery in nature. Among the most important impact modifiers in use today are butadiene-acrylonitrile copolymers (nitrile rubber), acrylonitrile-butadiene-styrene (ABS) graft terpolymers, methacrylate-butadiene-styrene (MBS) terpolymers, chlorinated polyethylene, and some polyacrylates.

CONT

The advantage of the [stretch blow molding] process is an improvement in resin performance, such as bottle impact strength, cold strength, transparency, surface gloss, stiffness, and gas barrier, which permit lighter weight, lower cost bottles, use of lower cost resins with less impact modifiers, or products packaged that normally would not be suitable.

CONT

Les antichocs sont des polymères (PE chloré) et surtout copolymères du type ABS ou MBS (méthacrylate-butadiène, styrène) qui forment des systèmes multiphases avec le polymère à renforcer et améliorent de ce fait sa résistance au choc. On les utilise en concentration de quelques pour cents, en particulier dans le PVC.
