Insulation material selection for din 41612 type q connectors manufacturer for different occasions from as7abecom's blog

Thermosetting plastics and thermosetting plastics are the insulating materials selected for aviation sockets, and urea-formaldehyde resins are thermosetting plastics. Compared with ordinary people, the fluidity of PPS is significantly increased by half, the molding cycle is shortened by half, the molding pressure is reduced by 40%, and 40% glass fiber can be added for reinforcement.

Thermosetting plastics and thermosetting plastics are the insulating materials selected for aviation sockets, and urea-formaldehyde resins are thermosetting plastics. Polydiallyl phthalate. Epoxy resin and unsaturated polyester; Is glass fiber reinforced thermosetting plastic PET, PBT, PCT, PA6, PA66, PA6T, PA9T. Propylene glycol polyphthalate ester. Polyether imide. Polyether sulfone. Polyaromatic sulfone, polyaromatic ether, etc.

If it is a low-frequency aviation socket, the material selected in the past is mostly mineral added phenolic plastic, but the production efficiency is low, so now it has been selected PA.PC. Enhanced PC and new thermosetting plastics such as polymers; If used in cold and wet conditions, DAP material can be used; If the application site has high sealing performance requirements, you can choose no sulfur or low sulfur rubber with good dielectric properties, such as silicone nitrile rubber and fluorine rubber; If it is a high frequency aviation socket, you can choose. GFPA class materials, these materials have low cost and good processing liquidity. Can produce thin wall products; If the dimensional stability and heat-resistant temperature requirements of the docking plug-in are high, GFPBT material can be selected; Only heat resistance requirements can be selected. PPS and LCP; If the pitch of the plug-in is only 1.27mm, in order to meet the dimensional accuracy and processing requirements, PES or PEI can be selected; If used for surface decoration, glass fiber reinforcement should be selected. PA46.PA6T.PA9T.PPA and other high heat resistant materials, due to the surface decoration should withstand 250℃, residence time is 5 seconds.

In order to fundamentally ensure the reliability of aviation sockets, appropriate insulating plastic materials must be selected according to the different requirements of different places.
