THERMOPLASTIC POLYURETHANE [11 records]

  • Wheels (Mechanical Components)

CONT

Casters are essentially housings that include a wheel and a mounting to install the caster to objects(equipment, apparatus and more). Casters are found virtually everywhere, from office desk chairs to shipyards, and from hospital beds to automotive factories. They range in size from the very small furniture casters to massive industrial casters... Wheel materials include cast iron, plastic, rubber, polyurethane, polyolefin, nylon, thermoplastic rubber, forged steel, stainless steel, aluminum, and more.

OBS

Casters come in two main categories: a swivel caster pivots around a kingpin to allow it to rotate and roll. The rigid (also called "fixed") caster has its wheel mounted in a fixed frame ... and it only rolls forward and backward.

CONT

As the name suggests, TPUs are thermoplastic resins. ... Most TPUs on the market today are synthesized using at least three different types of monomers: a polymeric compound containing a Tschugaeff-Zerewitinoff hydrogen, a diisocyanate, and a chain extender.

OBS

thermoplastic polyurethane; TPUR : term and abbreviation officially approved by the Lexicon Project Committee(New Brunswick).

French

Domaine(s)
  • Matières plastiques
CONT

Les polyuréthannes thermoplastiques sont des polymères linéaires avec des groupes uréthannes alternés avec des polyols. [...] En élevant la température, les liaisons entre chaînes sont rompues, permettant une mise en œuvre semblable à celles des thermoplastiques : (injection, extrusion, soufflage, thermoformage...). Des solvants peuvent aussi rompre ces liaisons permettant de préparer des solutions pour colles ou revêtements, et même extrusion de fils.

OBS

polyuréthanne thermoplastique; polyuréthane thermoplastique; TPUR : termes et abréviation uniformisés par le Comité du projet de lexiques (Nouveau-Brunswick).

Subject field(s)
  • Chemistry
CONT

A urethane is formed from the reaction of an isocyanate with an alcohol. In general, polyurethanes are made using a diisocyanate, a low molecular weight diol(thermoplastic) and/or triol(cross-linked), and a polyether glycol or a polyester glycol. If the reagents are difunctional, a non cross-linked thermoplastic polyurethane will be formed; if the functionality of at least one of the reagents is greater than two, a cross-linked or three dimensional network will form. Cross-linked polyurethanes exhibit less mechanical creep than non cross-linked polyurethanes. The rubbery modulus of polyurethanes increases as the level of cross-linking is increased. Polyurethanes are diblock copolymers. They consist of hard segments(isocyanate and the chain extender rich areas) that act as physical crosslinks, and soft segments(polyether or polyester glycol rich areas).

French

Domaine(s)
  • Chimie
CONT

Les adhésifs époxydes sont constitués de : [...] un (ou des) durcisseur(s) ou agent(s) de réticulation qui, par réaction chimique avec les groupements époxydes, permettent la formation du réseau tridimensionnel réticulé.

CONT

La structure des TD (résines thermodurcissables) a la forme d'un réseau tridimensionnel qui se ponte (double liaison de polymérisation) pour durcir en forme de façon définitive, lors d'un échauffement. La transformation est donc irréversible.
