Method for manufacturing a rubber article

摘要

A method of manufacturing a rubber article includes the steps of shaping a green article and blowing a solvent-free powdery release agent made of powder particles onto the green article in order to coat the green article with the release agent. The release agent contains at least 10% vulcanized rubber powder and a compound preventing rubber adhesion within the release agent. During blowing an electrostatic potential difference is provided between the green article and the release agent for driving the powder particles of the release onto the green article. The green article coated with the release agent is subsequently placed into a vulcanization mold where the green article is vulcanized.
