Benefits:
1, Hight temperature resistant: 220°C for wave pallet, 300°C for SMT pallet
2, environment-friendly, economy, recyclable
3, easy to install 
4, good surface luster, exellent corrosion resistance
5, to hold PCB securely in place
6, some models are ESD safe, the price is higher than non-ESD type

Application:for locking pcb on wave solder pallet.
It's used to be positioned PCB substrate in wave solder carriers,
fixtures and stencils to protect PCB substrate from floating and lifting
