Material performance of thermosetting cosmetic packaging material hose

Typical thermosetting cosmetic packaging material hoses are made of phenolic, epoxy, amino, unsaturated polyester, furan, polysilicon ether and other materials, as well as newer polydipropylene phthalate plastics. They have the advantages of high heat resistance and resistance to deformation when heated. The disadvantage is that the mechanical strength is generally not high, but the mechanical strength can be improved by adding fillers to make laminated materials or molded materials.


  Aniline, epoxy, polyvinyl chloride, polyamide, polyvinyl acetal and other modified phenolic resins can also be used to meet the requirements of different applications. Our cosmetic packaging material hose manufacturer suggested that phenolic resin can also be made into phenolic laminate, which is characterized by high mechanical strength, good electrical properties, corrosion resistance, and easy processing. It is widely used in low-voltage electrical equipment.


   Various fillers and additives can be added according to different uses and requirements. For varieties that require high insulation performance, mica or glass fiber can be used as filler; for varieties that require heat resistance, asbestos or other heat-resistant fillers can be used; for varieties that require seismic resistance, various appropriate fibers or rubber can be used as fillers And some toughening agents to make high toughness materials. Thermosetting cosmetic packaging hose made of phenolic resin as the main raw material, such as phenolic molded plastic (commonly known as Bakelite), has the characteristics of durability, dimensional stability, and resistance to other chemical substances except strong alkalis.


  Thermosetting cosmetic packaging material hose refers to plastics that can be cured under heat or other conditions or have insoluble (melting) characteristics, such as phenolic plastics, epoxy plastics, etc. Thermosetting plastics are divided into two types: formaldehyde cross-linked type and other cross-linked type. After thermal processing and forming, an infusible and insoluble cured product is formed, and the resin molecules are cross-linked into a network structure by a linear structure. Enhancing the heat will destructively destructively.
