Top mil-spec connector factory: Insulation material: The insulation material must meet the electrical, temperature, and mechanical properties requirements. Generally, the insulation material is selected based on the electrical properties, working temperature, and mechanical and environmental requirements of the electrical connector. The electrical properties mainly depend on the dielectric properties and volume resistivity of the material, the operating temperature depends on the thermal deformation temperature of the material, and the mechanical properties depend on the impact strength and bending strength of the material. Common insulating materials include thermoplastics (such as polyamide, polyvinyl chloride, ABS, PTFE, polyester, polyphenyl ether, etc.) and thermosetting …
