ROHS/REACH compliance substances exceeding standards in PBT injection molded parts
Problem Phenomenon
Restricted substances (such as specific flame retardants, heavy metals, etc.) are detected in PBT products exceeding the standards.
Cause Analysis
Use of non-environmentally friendly flame retardants (such as specific brominated flame retardants), catalyst residues or impurities in the raw materials, and contaminants introduced by recycled materials.
Solution
Select environmentally friendly flame-retardant PBT certified by ROHS/REACH; raw material suppliers provide compliance declarations; control the source of recycled materials.
Key Takeaway
PBT environmental compliance is a basic requirement for market access.
