1.Propiedad del producto<\/h4>\n

 <\/p>\n

L\u00edquido incoloro transparente o amarillo p\u00e1lido inflamable. Tiene un fuerte olor irritante. Es miscible con etanol (en descomposici\u00f3n), dietilenglicol, \u00e9ter, acetona, tetracloruro de carbono, benceno, clorobenceno, queroseno y aceite de oliva. El diisocianato de tolueno (TDI) tiene seis is\u00f3meros: 2,3-TDI, 2,4-TDI, 2,5-TDI, 2,6-TDI, 3,4-TDI y 3,5-TDI. Entre ellos, el 2,4-TDI y el 2,6-TDI son los m\u00e1s comunes, y los productos industriales suelen ser una mezcla de 2,4-TDI y 2,6-TDI.<\/p>\n

3.\u00c1mbito de aplicaci\u00f3n y uso<\/h4>\n

Se utiliza como materia prima para la fabricaci\u00f3n de pl\u00e1sticos de espuma blanda de poliuretano, revestimientos, caucho y adhesivos.<\/p>\n

4.Embalaje y almacenamiento<\/h4>\n

Los envases habituales son botellas de vidrio de 500 ml, botellas de vidrio con tapones de hierro y cuellos sellados, o botellas de pl\u00e1stico. Para grandes cantidades, suelen utilizarse bidones met\u00e1licos (como los de hierro galvanizado) o dep\u00f3sitos de acero inoxidable.<\/p>\n

Debe almacenarse en un lugar fresco y seco. La temperatura recomendada es de 20-35\u2103. Evite las temperaturas elevadas, ya que pueden provocar su descomposici\u00f3n.<\/p>","protected":false},"excerpt":{"rendered":"
