Characteristics of special modified PBT for coil framework:

1. High grade flame retardant

For general electronic products, in terms of data selection, special attention is paid to its fire prevention function. Selecting high-level fire prevention data has a very important meaning for improving product safety level and preventing fire.

Especially for the information about the coil framework, when the coil current winding the framework is too large, it will often cause the coil to heat up or even burn out, and the information that the flame retardant grade cannot meet the requirements will inevitably have certain potential safety hazards

The special modified PBT for coil framework can reach the level of 0.38mmv0, ensuring the safety of coil framework in safe operation.

2. High CTI

Comparativetracking index (CTI): the highest voltage value that the data surface can withstand 50 drops of electrolyte (0.1% ammonium chloride aqueous solution) without the formation of leakage traces. Polymer insulation materials have a special phenomenon of electrical damage, that is, the surface of polymer insulation materials will deteriorate under specific conditions, and can lead to electrical damage.

As for the products used in some electronic components such as coil framework, they have high requirements for CTI value. The specially modified PBT for coil frame not only has excellent flame retardancy, but also has excellent leakage trace index, which can reach 250V and has excellent safety function.

3. High mechanical function

General electronic products do not pay special attention to the mechanical function in the selection of data, but for some special parts, if the mechanical function is lacking, the parts will crack or the parts will be brittle. Therefore, it has a very important meaning for customers to prevent the use of defective products and improve the mechanical function of products.

4. High liquidity

As for a material, good fluidity means easy processing and molding, lower processing temperature, lower injection pressure and lower power loss. In particular, for the "the first mock examination with multiple holes" products such as relays, capacitor shells and coil frames, selecting a material with good liquidity is more beneficial to injection molding and prevents the parts from being dissatisfied or defective due to lack of liquidity. Special modified PBT for coil framework has good fluidity and excellent processing function.
