Precautions For The Use Of Mold Release Agent

Update:2021-08-27 00:00
Summary:

Mold Release Agent is a functional substance between the mold and the finished product. The release agent is chemically resistant and will not be dissolved when it comes in contact with the chemical components of different resins (especially styrene and amines). The release agent also has a heat resistance and stress properties, and is not easy to decompose or wear; the release agent adheres to the mold and does not transfer to the processed part, and does not interfere with painting or other secondary processing operations. Due to the rapid development of injection molding, extrusion, calendering, molding, laminating, and other processes, the amount of release agent has also been greatly increased.

 

The release agent is an interface coating used on the surface of two objects that are easy to adhere to. It can make the surface of the object easy to peel off, smooth, and clean. It is widely used in metal die-casting, EVA products, rubber products, plastic products, silicone products, cement products, polyurethane foam and elastomers, glass fiber reinforced plastics, injection molding thermoplastics, vacuum foaming sheets, and extrusion profile fillers Such as plasticizers, etc. will ooze out to the interface, then a surface remover is needed to remove it.

 

Theoretically, the release agent has greater tensile strength, so that it is not easily polished when it is in frequent contact with the molded resin. This is especially true when there are frosted mineral fillers or glass fiber reinforcements in the resin. The release agent is chemically resistant and will not be dissolved when it comes in contact with the chemical components of different resins (especially styrene and amines). The release agent also has a heat resistance and stress properties, and is not easy to decompose or wear; the neutral release agent adheres to the mold and does not transfer to the processed part, and does not interfere with painting or other secondary processing operations.
