Shoe sole mold release agents

The most common materials for the formation of soles range from elastomers such as polyurethane, rubber and even some other synthetics such as EVA and EPDM. Depending on the requirements and mechanical properties (strength and weight), manufacturers use one or more of these for the manufacture of their footwear.

The processes for the manufacture of soles and other footwear accessories are injection, injection to cut and vulcanizing in press. Each of them has different features and challenges that Intermol together with the manufacturer can solve together.

The role of a good release agent is key to the mass production of soles, as it helps to make the parts of a higher quality. In addition, a release agent with good performance can extend the life of the molds, which can translate into higher profits for the manufacturer.
Also, a mold release for footwear should help to fulfill in the best way the post-processes of the mold release area such as: painting, gluing and detailing, an ideal mold release should not interfere or increase the workload.
