Rubber Release Agent With Heat And Stress Performance

Jul 14, 2017

The Rubber Release Agent is a functional substance between the mold and the finished product. The Rubber Release Agent is chemically resistant and is not dissolved when contacted with the chemical composition of different resins, especially styrene and amines. The Rubber Release Agent also has heat and stress properties, is not easy to break down or wear; Rubber Release Agent bonded to the mold without being transferred to the workpiece to be processed, without prejudice to painting or other secondary processing operations. As the injection molding, extrusion, calendering, molding, laminating and other rapid development of the process, the amount of Rubber Release Agent is also greatly improved.

In theory, the Rubber Release Agent has a large tensile strength so that it is not easily polished when it is in constant contact with the molded resin. This is especially true when there are frosted mineral fillers or glass fiber reinforcements in the resin. The Rubber Release Agent is chemically resistant and is not dissolved when contacted with the chemical composition of different resins, especially styrene and amines. The Rubber Release Agent also has heat and stress properties, is not easy to break down or wear; Rubber Release Agent bonded to the mold without being transferred to the workpiece to be processed, without prejudice to painting or other secondary processing operations.

The effect of the Rubber Release Agent is to smoothly remove the cured product from the mold to obtain a smooth and smooth product and to ensure that the mold is used multiple times

The main requirements for the Rubber Release Agent are: have a certain thermal stability and chemical inertia, does not corrode the cavity surface; in the cavity surface residual decomposition products; does not affect the product color, but can give a good appearance, non-toxic; Preparation, easy to use.

Rubber Rubber Release Agent refers to a type of substance used to prevent the rubber product from adhering to the surface of the mold and to make it smooth and not to be torn. When used, it is sprayed or applied to the cavity surface to form an effective barrier. The use of rubber Rubber Release Agent is here.

Rubber Rubber Release Agent is between the mold and the product between the functional substances in the rubber, plastic manufacturing industry, manufacturing model products, in order to mold, improve production efficiency and extend the life of the mold, while the product smooth, qualified , To reduce waste, and the need to use an essential additive. Its main function is to make the stripping operation easy, to prevent the removal of the product caused by damage. Separation of Rubber Release Agent depends on its surface properties, its significant feature is the critical surface tension is small, it is difficult to be liquid wetting, because of this, in order to achieve the role of stripping.

Types of rubber Rubber Release Agents Classification:

1, rubber Rubber Release Agent: refers to the rubber products used to prevent the adhesion of the mold surface, and can make it a smooth mold without tearing a class of substances. When used, it is sprayed or applied to the cavity surface to form an effective barrier. The main requirements for the Rubber Release Agent are: have a certain thermal stability and chemical inertia, does not corrode the cavity surface; in the cavity surface residual decomposition products; does not affect the product color, but can give a good appearance, non-toxic; Preparation, easy to use.

2, fluoride Rubber Release Agent: fluoride Rubber Release Agent inherited the characteristics of fluorine-containing materials, can significantly reduce the surface energy of the solid, making it difficult to infiltrate and non-sticky, easy to dissolve with other substances, a good solution Finished product and the adhesion between the mold, the preparation of Rubber Release Agent, the amount of fluorine compounds is minimal. It is suitable for thermosetting resin, thermoplastic resin and various rubber parts. The surface of the molded article is smooth and the secondary processing performance is excellent, especially suitable for the stripping of fine electronic parts.

3, silicon Rubber Release Agent: silicone Rubber Release Agent is made of organic silicon oxide as raw materials, the advantages of good heat resistance, moderate surface tension, easy to become evenly separated membrane, stripping long life. The disadvantage is that after stripping the surface of the product has a layer of oil-like surface, the second processing must be carried out surface cleaning. Commonly used silicone oil, silicone rubber, silicone oil and silicone grease. Silicone Rubber Release Agent is the current rubber and plastic Rubber Release Agent mid-range market mainstream products, in the polyurethane, rubber, and other resin processing are widely used.

4, wax (oil) Rubber Release Agent wax oil series Rubber Release Agent is characterized by low prices, sticking performance, the disadvantage is pollution mold, the main varieties are
