Latex is a natural material extracted from the Hevea brasiliensis or ‘rubber tree’. The elasticity that natural rubber latex (NRL) provides makes it ideal for use in a range of applications. Latex was first used in latex gloves in the late 1800s. High levels of flexibility and comfort make them popular in the domestic market, medical facilities, and catering businesses, but they pose an inherent risk to those with latex allergies.
Vinyl is man-made material often chosen over other materials because of its low cost, versatility and performance properties.
Vinyl glove is a pretty cheap budget choice due to the easy production and low cost raw material. They are widely used in restaurant, food preparation, cleaning etc. Disposable vinyl gloves can be less tough and last less time than their alternative materials like Nitrile and rubber latex.
