Introduction of Release Agent for Rubber Mandrel:
Mandrel release agents are special release agents for hoses, which can make the molding of unvulcanized hoses and demolding of vulcanized hoses easier. Mandrel release agents are general-purpose hose release agents that can be used for almost all types of non-polar and medium-polar rubber compounds, even including ECO. Mandrel release agents are particularly effective for CR, EPDM and CM. Mandrel release agents have good lubrication effect when uncured rubber hose is molded and vulcanized rubber hose is demolded, and do not contain any organic silicon substances.
Key Points of Release Agent for Rubber Mandrel Operation:
Depending on the rubber type of the hose used and the design of the metal tube core, mandrel release agents can be used directly. According to the specific process conditions, they can be used with a certain proportion of water (the maximum ratio cannot exceed 1:2). The amount of mandrel release agents used depends on the actual process conditions of each factory. Core tube rubber mold release agents can be directly brushed on the core mold or the uncured rubber hose can be directly immersed in it. Core tube rubber mold release agents do not corrode the tube core, but must have a general warning sign of industrial hygiene.

Precautions for Core Rubber Mold Release Agents:
Core release agents for rubber hoses can be stored in the original sealed packaging at room temperature and in a dry place for one year. Keep the container tightly closed and store in a dry and ventilated place. Opened containers must be carefully resealed and kept in an upright position to prevent leakage. Electrical installation construction materials must meet technical safety standards. Core release agents for rubber hoses are not allowed to be discharged into sewers, waterways or soil. Do not contaminate pools, waterways and ditches with chemicals or used containers. Core release agents for rubber Hoses should be sent to a licensed waste management company. Do not reuse the empty core tube release agents for rubber hoses container.
