Environmental And Safety Standards For Push-in Terminal Block Materials

push in wire terminal block At the materials engineering level, a formula that does not contain any harmful halogens must be used to meet industry standards and market expectations for environmental safety. These materials do not release high levels of halogen gases under combustion conditions, improving the overall air quality performance of the system.

For push wire terminal block insulators, polymeric materials such as polyamides (e.g., PA66) and polycarbonates are widely used due to their mechanical strength and thermal stability. Halogen-free flame-retardant systems achieve the necessary balance between flame-retardant performance and environmental standards by introducing phosphorus-based flame-retardant additives to replace surface halogen elements.

In push in terminal block design, the smoke density and toxicity emission indicators of the material system are part of the engineering assessment. This adjustment responds to the ongoing needs of both safety and environmental protection.
