Abstract
Los artículos de látex de caucho natural están extensamente presentes en nuestra sociedad, ya que se cifran en más de 40,000 los artículos que contienen látex, incluyendo más de 400 dispositivos bio‐médicos. Este éxito se debe a que es un material idóneo para fabricar artículos de paredes muy delgadas con excelentes propiedades barrera y elásticas. Estas propiedades barrera proporcionan una protección muy eficaz contra virus y bacterias que, unidas a la durabilidad, costo y confort, han hecho de los artículos de látex de caucho natural un material fundamental en bio‐medicina y otros productos biosanitarios. Además, el cultivo de caucho natural y su proceso de transformación agroindustrial desempeñan un papel de gran importancia a nivel socioeconómico en países en desarrollo y en la economía global. Asimismo, estas plantaciones cumplen funciones reforestadoras, son fuente de captura de carbono y por tanto sumidero de CO2, generando O2 y madera como subproductos. Sin embargo, a pesar de la utilización masiva de estos productos y su indudable beneficio para la sociedad, no están exentos de ocasionar problemas derivados de su uso. En este trabajo se plantean nuevos desarrollos en este campo que permiten prestar una atención especial a la resolución de los problemas que presentan estos materiales...
Natural rubber latex products are ubiquitous in our society. There are more than 40.000 products commercially available that contain latex, including more than 400 biomedical devices. This success is due to its suitability for manufacturing thin‐walled products and articles yet having excellent barrier and elastic properties. Barrier properties confer effective protection against viruses and bacteria, which, together with their durability, cost and comfort, make the use of rubber latex products absolutely indispensable in bio‐medicine and bio‐health applications. In addition, the cultivation of natural rubber tree (Hevea brasiliensis) and the agro‐industrial transformation processes of natural rubber play an important socio‐economical role in developing countries and in the global‐world economy. Also, these plantations accomplish reforestation functions; they are sources of carbon capture so they drain CO2, generating O2 and wood as sub‐products. Nevertheless, in spite of the widespread use of these products ‐and their undoubtedly benefit for the society‐, they are not exempt of causing problems associated with their employment. Herein, the present work has been specifically drawn up to address those issues through a rational design of new formulations for natural rubber latex...
