What Dissolves Latex? | eHow
Latex is a natural, creamy liquid substance that forms from under the bark of rubber trees. Found in items such as balloons, rubber toys, bandages, pacifiers, baby bottle nipples, dental supplies, condoms, masks and costumes, Latex is the primary material contained in rubber household gloves and many types of house paint.

Styrene Butadiene Rubbers, SBR - Adhesives Ingredients
Styrene Butadiene Rubber (SBR) is the most widely used synthetic rubber in adhesives & sealants and is produced from copolymer of styrene and butadiene. SBR adhesives show excellent heat, abrasion and crack resistance and better ageing characteristics than natural rubber adhesives.

Natural rubber
Natural rubber, also called by other names of India rubber, latex, Amazonian rubber, caucho or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water. Thailand and Indonesia are two of the leading rubber producers.

Compounding Of Rubber - SlideShare
• The field latex which is known as unconcentrated latex is not suitable for commercial use as it contains considerable amount of non-rubber constituents and too much water in it. • The latex is therefore concentrated to about 60% rubber solids before it is used to make rubber products.

serviceability. The rubber particle is generally oval having < 5 micron particle size and a typical particle size distribution. The aqueous phase consists of dissolved and suspended matters and knowledge of their concentration, acidic / basic nature (pH) is essential for successful latex compounding. Latex products are subject to degradation and adequate antioxidant protection is necessary.

Rubber and Latex Both rubber and latex are important for 3D printing allow parts to be designed with flexible joints, gaskets, sleeves etc. Rubber cement can work surprisingly well. However latex and many robust rubbers need to be primed or dissolve with N- heptane is a good solvent for latex and most rubbers.
