Latex processing is much different. Latex is compounded in its natural liquid form. Mastication is not required. The compound ingredients are made into water dispersions which are added to the latex. The compound ingredients are more evenly distributed in with the micron size polymer particles and the result is a product with greater tear resistance and superior physical properties. This is one reason why medical exam gloves, condoms, and balloons are made from latex and not from dry stock. Processing latex into a finished product is more time consuming, tedious, and hands-on, but the end result is a better product.
It is used in many applications.
