Elastomeric parts are made by a variety of techniques including injection and compression molding, continuous extrusion and hand built. All of these use dry rubber manufacturing techniques. Parts are also made by a liquid process called dipping. In this technique raw liquid dispersions are first compounded with the proper formulating ingredients. The liquid compound is placed in a tank into which are lowered forms, typically porcelain, and held while the liquid dispersions compound slowly builds thickness on the form. The form is then withdrawn yielding a uniform coating of rubber composition. After drying and curing, the part is stripped off of the form for finishing operations.

The main application for this process is the production of thin wall parts where molding would be difficult to control. Examples are supported and unsupported gloves, convoluted boots, weather and toy balloons, play balls, metal and fiber coatings, and related industrial and consumer applications. Neoprene polychloroprene liquid dispersions are well suited to this manufacturing process due to the high initial strength of the deposited film combined with its well known balance of final properties, including heat and ozone resistance, weatherablity, oil and chemical resistance and tear strength to name a few.

Neoprene liquid dispersions must be compounded to achieve desirable properties. For additional details either on the dipped goods process or about Neoprene liquid dispersions and formulating, please request additional information by e-mail or call 1-800-853-5515.
