The product obtained is a silicone rubber.
Le platine reste évidemment rions le produit fini.Platinum obviously remains the finished product.
Un matériau particulièrement intéressant pour cette opération est Je produit designé sous l'appellation DTV. L. D. 2082 et commercialisé nor la Société RHONE POULENC. A particularly interesting material for this operation is the product designated under the name DTV. L. D. 2082 and marketed by the RHONE POULENC Company.
Les modalités du traitement de réticulation doivent être définies avec précision pour donner un produit fini qui présente une ressemblance correcte avec l'organe naturel. The modalities of the crosslinking treatment must be precisely defined to give a finished product which presents a correct resemblance to the natural organ.
Le mélange des produits A et B est avantageusement opéré à température @@biante Sans un mélongeur nar jet à turbine durant deux fois cinq minutes. The mixing of products A and B is advantageously carried out at @@ biante temperature Without a turbine jet nar mixer for twice five minutes.
L@ Proportion du constituant A dans le mélange est comnrise entre 25% et 35% du poids du mélange total et, de préférence, entre 29% et 32, 3.1 idéal se situant à 31,5. L @ Proportion of component A in the mixture is between 25% and 35% of the weight of the total mixture and, preferably, between 29% and 32, 3.1 ideal lying at 31.5.
Celle du constituant B est comprise entre 65 et 75% en poids du mélange total, et de préférence entre 68 et 71", l'idéal étant atteint à 68,5%. That of component B is between 65 and 75% by weight of the total mixture, and preferably between 68 and 71 ", the ideal being reached at 68.5%.
Après malaxage, le mélange est versé dans un moule préchauffé (700C) et enduit de démoulant (savon à base non oléngineuse) puis placé dans une étuve dont la température est comprise entre -80 et 100 degrés centigrades et à 900 rie nréférence pendant une Jurée qui est comprise entre 30 et 60 minutes selon la taille et la masse du moule. After kneading, the mixture is poured into a preheated mold (700C) and coated with release agent (non-oil based soap) then placed in an oven whose temperature is between -80 and 100 degrees centigrade and at 900 rie reference during a Juror which is between 30 and 60 minutes depending on the size and mass of the mold.
Le moule est fait de résine enoxy LAB 508 renforcée à 302 de limaille d'aluminium et subit qvant sa mise en service , un trcitement thermique qu; le rend stable. The mold is made of LAB 508 enoxy resin reinforced with 302 aluminum filings and undergoes, before being put into service, a thermal treatment that; makes it stable.
Dour faciliter l'ariaptation rie la nrothèse sur la sujet, mas également pour alléger et rendre nlvs souple le matériau, la face interne de la prothèse, la plus proche de la peau doit être de forme concave et la concavité peut être caractérisée par la distance entre le point le nus profond et un plan s'appuyant sur la périphérie externe de la prothèse, cette distance variable selon la taille rie la prothèse est comprise entre 8mm et 15mm. To facilitate adaptation, the prosthesis on the subject, but also to lighten and make flexible the material, the internal face of the prosthesis, the closest to the skin must be of concave shape and the concavity can be characterized by the distance between the point of the deep nude and a plane resting on the external periphery of the prosthesis, this distance varying according to the size of the prosthesis is between 8mm and 15mm.

Le moile est réalisé en Jeux nièces , une base (l) renrésenttant en creux la forme d'un sein et un couvercle (2) rie forme convexe qui vient plonger dans la base pour assurer la concauité interne de la prothèse. The moile is produced in niece sets, a base (1) recessing in hollow the shape of a breast and a cover (2) in a convex shape which comes to plunge into the base to ensure the internal concauity of the prosthesis.
Le couvercle repose sur la base par 3 'intermédiaire de pontets (3,4,5,6) solidaires du couvercle et venant s'emboiter rions des évidements (7,8,9,10) de la base. The cover rests on the base via 3 'bridges (3,4,5,6) integral with the cover and coming to fit together with the recesses (7,8,9,10) in the base.
L'espace (11) prévu entre le couvercle et la base permet aux dilatations Au produit traité de se faire librement. The space (11) provided between the cover and the base allows the processed product to expand freely.
Bien que la prothèse soit utilisable à l'étot nu, elle est livrée enfermée dans Jeux enveloppes en tissu. Although the prosthesis can be used naked, it is delivered enclosed in sets in fabric envelopes.
La première enveloppe destinée à absorber un suintement éventuel et à laisser respirer l'elastomère est constituée d'un tissu en fibre synthétique ANTRON III Je "upont rie NEuOURS. The first envelope intended to absorb a possible seepage and to let breathe the elastomer consists of a fabric in synthetic fiber ANTRON III Je "upont rie NEuOURS.
L'rnconvénient rie ce tissu est rie produire nnrfois ries irritations au contact rie la pe@u sur certains suets allergiques. The drawback of this fabric is that it sometimes produces irritation on contact with the skin on certain allergic foods.
Pour éviter cet inconvénient, l'ensemble formé par la prothèse et la première enveloppe est placé à nouve@u Arns une deuxième enveloppe 1002 coton qui ne donne aucune réaction cutanée. To avoid this drawback, the assembly formed by the prosthesis and the first envelope is placed again @ u Arns a second envelope 1002 cotton which gives no skin reaction.
Les coutures des enveloppes réalisées nu moyen d'une surjeteuse raseuse sont retournées vers l'intérieur du dispositif, ne produisant ainsi aucune gene ou irritation rie la peau et goronti sont un confort total, renforcé nar le profil en courbes étudiées de la prothèse. The seams of the envelopes made by means of a shaving serger are turned towards the inside of the device, thus producing no discomfort or irritation on the skin and goronti are total comfort, reinforced by the profile in studied curves of the prosthesis.
Après démoulage, la prothèse est enduite rie talc officinal pour absorber les résidus huileux et honneur meilleur aspect nu produit. After demoulding, the prosthesis is coated with officinal talc to absorb oily residues and to honor the best appearance of the product.
