Connector manufacturers have been trying to provide the best performance at the lowest cost connector, end users, however, want to buy at the lowest price with the best connector.

   
The performance of the connector body, largely depends on the physical characteristics of the use of engineering plastics. The connector body must have good physical properties and manufacturing performance. The polymer must provide a good toughness and dimensional stability, while having a high impedance and electrical insulating properties. The polymer should also meet the needs of the end use, for example: chemical resist force, the flame resistance, a short-term thermal stability, long-term aging ability and other forming performance. Toughness and impact properties like performance in a certain environment will weaken.

   
Such performance is inherent in the plastic, but are often added to the additive in order to achieve a particular level of performance. Typical additives include talc and glass fibers, which can improve the physical characteristics of the plastic, and can contribute to the flame retardant. Glass fiber additives can improve the capacity of the filling of the mold the thin-walled portions. Mica and talc, the effect of improved dimensional stability, especially in the semi-crystalline polymer, in order to increase the flow and lubrication, may also be added other additives.

   
Decided to make the connector body with the raw material, the end use of the connector and in the molding process of the production stage experience plays an important role.
