LATEX COMPOSITION FOR DIP FORMING AND DIP-FORMED ARTICLE PREPARED THEREFROM
Provided is a latex composition for dip forming which includes 100 parts by weight of a nitrile-based hybrid latex including a first latex and a second latex which have different glass transition temperatures, and 2 parts by weight to 8 parts by weight of an ion-conductive polymer having a weight-average molecular weight of 400 to 1,000. The latex composition for dip forming has excellent low-temperature stability and a dip-formed article prepared using the composition has excellent tensile strength and elongation. Since wearing comfort is improved due to a decrease in modulus, the dip-formed article may be suitable for industries requiring such properties.
