What Are The Characteristics Of Nylon Cable Connector Materials

What are the characteristics of nylon cable connector materials:

Nylon Cable Gland refers to plastics made of polyamide resin. Nylon cable connectors are made of diamine and dibasic acid through polycondensation, or by ring-opening polymerization of lactam formed by amino acid dehydration. Unlike PS, PE, PP, etc., nylon cable connectors do not soften gradually with the increase of heating temperature, but soften in a narrow temperature range close to the melting point. The melting point is very obvious, melting point: 215-225 "C. Once the temperature is reached, it will flow.

Nylon cable connectors are keratinous, tough, shiny, white (or milky white) or slightly yellow, transparent or translucent crystalline resins in appearance, which are easy to be dyed into any color. As an engineering plastic, the molecular weight of nylon cable connectors is generally 15,000-30,000. Nylon cable connectors have a density slightly greater than 1, and the density of nylon cable connectors is 1.14-1.15g/cm3. Tensile strength: > 60.0MPa. Elongation: > 30%. Bending strength: 90. 0MPa. Notch impact strength: (kJ/m2) > 5,

The shrinkage rate of nylon cable connector is 1%~2%. It is necessary to pay attention to the dimensional change of moisture absorption after molding. The water absorption rate is 100%, and it can absorb 8% relative to moisture absorption saturation. The use temperature can be between 40~105C. Melting point: 215~225C. Suitable wall thickness 2~3.5mm. The mechanical properties of PA, such as tensile and compressive strength, change with temperature and moisture absorption, so water is relatively a plasticizer for PA. After adding glass fiber, its tensile and compressive strength can be increased by about 2 times, and the temperature resistance is also improved accordingly. The wear resistance of nylon cable connector itself is very high, so it can be operated continuously without lubrication. If you want to get a special lubrication effect, you can add sulfide to the nylon cable connector.
