Nettet1. des. 2001 · Mold fouling is a commonly seen phenomenon in the rubber processing industry. During vulcanization, a layer is deposited on the wall of the mold which builds up gradually with each subsequent production cycle. This layer impedes an adequate heat transport, is the source of release problems and results in products with irregular surfaces. NettetVamc® Ultra IP has lower mold fouling. An internal test is used to compare the mold-sticking characteristics of small O-rings that are compression molded. The test employs a mold with two sets of 60 cavities. After each vulcanization cycle, the O-rings are blown out by pressurized air of defined pressure under conditions of defined
