Mold Release Agent Manufacturer-Meiyahg

Mold Release Agent, is an interface coating used on the surface of two objects that are easy to adhere to each other. It can make the surface of the object easy to peel off, smooth and clean.

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 heat resistance and stress properties, and is not easy to decompose or wear; the release agent adheres to the mold without transferring to the processed part, and does not interfere with painting or other secondary processing operations.

The specific work principle of the release agent is as follows:

• The polar chemical bond interacts with the mold surface to form a regenerative adsorption film;
• The silicon-oxygen bond in polysiloxane can be regarded as a weak dipole (Si+-O-). When the release agent is spread on the mold surface into a single orientation arrangement, the molecule adopts a unique extended chain configuration;
• The free surface is covered by alkyl groups in a densely packed manner, and the mold release ability increases with the density of the alkyl group; but when the alkyl group occupies a large steric hindrance, the stretching configuration is limited and the mold release ability will be reduced;
•  The molecular weight and viscosity of the release agent are also related to the release ability. The molecular weight is small and the spreadability is good, but the heat resistance is poor.

Types Of Release Agent

Release agents are 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 thermoplastics, vacuum foam plastic sheets and other material. In our mold release company, we mainly provide the products below:

• By Usage: internal release agent, external release agent;

• By Service Life: conventional release agent, semi-permanent release agent;
• By Form: solvent-based release agent, water-based release agent, solvent-free release agent, powder release agent, paste release agent
• By Active Substance:

①Silicon Release Agent-mainly silicone compound, silicone oil, silicone resin methyl branched silicone oil, methyl silicone oil, emulsified methyl silicone oil, hydrogen-containing methyl silicone oil, silicone grease, silicone resin, silicone rubber, silicone rubber toluene solution

②Wax Series-plant, animal, synthetic paraffin; microcrystalline paraffin; polyethylene wax, etc.

③Fluorine Series-the best isolation performance, low mold pollution, but high cost Polytetrafluoroethylene; fluorine resin powder; fluorine resin coating, etc.

④Surfactant Series-metal soap (anionic), EO, PO derivatives (non-ionic)

⑤Inorganic Powder Series-talc, mica, clay, white clay, etc.

⑥Polyether series-a mixture of polyether and fat oil, which has good heat resistance and chemical resistance, and is mostly used in certain rubber industries that have restrictions on silicone oil. The cost is higher than that of silicone oil series.
