Long-chain alkyl silicone oil has excellent demoulding performance. The following is a detailed introduction to its demoulding performance:

Forming an effective isolation film: Long-chain alkyl silicone oil can spread and adhere evenly between the mold and the molding material to form a continuous, stable and moderately thick isolation film. This isolation film can effectively block the direct contact between the mold and the molding material, greatly reducing the surface tension and friction between the two, so that the molded product can be easily separated from the mold, and ensure that the surface of the product is smooth and complete, without defects such as tearing, damage or sticking

No impact on the secondary processing of the product: When long-chain alkyl silicone oil is used as a demoulding agent, its residue on the surface of the product is very small and will not have a negative impact on the surface performance of the product. This means that the demoulded product can directly carry out subsequent processing operations, such as printing, coating, welding, assembly, etc., without additional surface treatment to remove the release agent residue, which not only improves production efficiency, but also reduces production costs, while also ensuring that the quality and performance of the product are not affected.

Applicable to demoulding of a variety of materials: Long-chain alkyl silicone oil has a good demoulding effect on a variety of common molding materials, including plastics, rubber, polyurethane, etc. In plastic molding, such as polyethylene, polypropylene, polystyrene, etc., it can significantly reduce the adhesion between the plastic melt and the mold, making the plastic products easy to demold; for rubber products, such as natural rubber, synthetic rubber, etc., long-chain alkyl silicone oil can improve the fluidity and demolding performance of rubber, and improve the production efficiency and quality of rubber products; in the production of polyurethane products, long-chain alkyl silicone oil is an excellent demolding agent, which can effectively solve the problem of high viscosity and difficult demolding of polyurethane materials, and ensure the smooth demolding and surface quality of polyurethane products.

Internal and external demolding agents: long-chain alkyl silicone oil can be directly applied or sprayed on the mold surface as an external demolding agent, or added to the molding material as an internal demolding agent. When used as an external demolding agent, the operation is simple and convenient, and a demolding layer can be quickly formed on the mold surface; when added to the molding material as an internal demolding agent, it can be evenly dispersed inside the material, and gradually migrate to the interface between the material and the mold during the molding process to play a demolding role. This dual characteristic of internal and external mold release agents enables long-chain alkyl silicone oil to be flexibly applied under different production processes and requirements, bringing greater convenience to production.

Good thermal stability and chemical stability: During high-temperature molding, long-chain alkyl silicone oil can maintain stable performance and will not decompose, volatilize or deteriorate due to high temperature, thus always effectively playing a demolding role. At the same time, it has good tolerance to common chemical substances and is not easy to react chemically with molding materials or mold surfaces, ensuring the reliability and durability of the demolding effect, making it suitable for a variety of different production environments and process conditions
