Converting non-metallic printed circuit boards waste into a value added product

“…Another recent study done by Liang and his co-workers found that the molecular chain of polyolefin (PP,PE etc.) is lack of active groups, so it is hardly to form effective interface adhesion because of its poor affinity composite with glass fibers, as a result, stress cannot be transferred to glass fibers well by matrix resin [ 9 ]. The enhancement of glass fiber weakens greatly, and this will also influence the performances of the composites.…”

Thermal Debromination of Waste Printed Circuit Boards by Iron-Based Catalyst

“…The most commonly WPCBs material is FR-4 which using glass fibers as the reinforcing materials and brominated epoxy resins (BERs) as a binder [1,2]. BERs containing a large number of brominated flame retardants (5%-15%, BFRs) which are widely used in the PCBs to reduce the possibility of fire under the thermal stress [3].…”
