Rubber mold release agents are generally divided into two types: external and internal. Traditional mold release agent - generally for external use, that is, coated on the surface of the mold cavity, customarily also known as isolation agent, the products are mainly talc, mica powder, paraffin wax, PTFE and silicone oil, etc., they have a certain degree of demolding effect, but with the easy to leave the mold scale and traces of the mold corrosion, the price of the more expensive and other shortcomings. In the many varieties of mold release agent, fluorine, silicon mold release agent because of its good mold release effect, suitable for mold release mold material, is the faster development of two types of mold release agent in recent years. The main requirements of the release agent is: a certain degree of thermal stability and chemical inertia, do not corrode the surface of the mold cavity; residual decomposition under the surface of the mold cavity; does not affect the color of the product, but can give a good appearance, non-toxic; easy to formulate, easy to use.
Rubber mold release agent refers to a class of substances used to prevent rubber products and mold surface adhesion, and can make it smooth out of the mold without tearing. When used, it will be sprayed or coated on the surface of the mold cavity to form a layer of effective isolation. The use of rubber mold release agent is here. Rubber mold release agent is a functional material between the mold and the product in the rubber, plastic manufacturing I industry, the manufacture of model products, in order to release the mold, improve productivity, extend the service life of the mold, and at the same time to make the product clean, ruler when qualified, reduce scrap, and the need to use an indispensable additives. The main function is to make The main function is to make the demolding operation easy, to prevent forced removal of the product damage caused by the isolation of the mold release agent depends on its surface properties, its significant feature is the critical surface tension is small, it is difficult to remove the product. Its distinctive feature is that the critical surface tension is small and it is difficult to be wetted by the liquid, because of this, it can achieve the function of mold release.
