First, Shenzhen Kenhon Technology is mainly engaged in the research, development and production of waterproof plugs with cords. The material used is PA66.
PA66 is also called nylon and has the following characteristics:
1, has excellent wear resistance, self-lubricating, high mechanical strength. However, the water absorption is large and the dimensional stability is poor
2. PA66 also maintains strong strength and stiffness at higher temperatures. PA66 is still hygroscopic after molding, and the extent depends on the composition, wall thickness, and environmental conditions of the material.
3. When designing products, we must consider the effect of hygroscopicity on the geometric stability. In order to improve the mechanical properties of PA66, various modifiers are often added. Glass is the most common additive, and synthetic rubbers such as EPDM and SBR are sometimes added to improve impact resistance. PA66 is less viscous and therefore fluid (but not as good as PA6). This property can be used to process very thin components. Its viscosity is sensitive to temperature changes.
4. The shrinkage of PA66 is between 1% and 2%. Adding glass fiber additive can reduce the shrinkage to 0.2%~1%. The difference in shrinkage between the flow direction and the flow direction is greater. PA66 is resistant to many solvents, but less resistant to acids and other chlorinating agents.
Advantages: high tensile strength; 2, resistance to toughness, excellent impact resistance; 3, self-lubricating, good wear resistance, excellent chemical resistance; 4, good low-temperature properties; 5, with self-extinguishing;
Waterproof plugs made of this material are stable and cold-resistant, excellent resistance to toughness and impact resistance, and are the materials of choice for waterproof connectors.
Second, the product terminals solid copper terminal
Shenzhen Kenhon Technology always regards product quality as the life and soul of the enterprise. The first concern for customers of waterproof plug material is whether the terminal is a pure copper terminal. There are many other materials on the market instead of copper, which not only affects the safety performance of the product. , but also affect the product's life.
As a professional manufacturer of waterproof plugs for ten years, we will always put product quality first, and provide new and old customers with more cost-effective products.
