Conductive ESD FOAM MSCD 25
Conductive ESD FOAM MSCD 25
SHORT DESCRIPTION:
Surface resistance value of ESD foam：
● 10^3 to 10^5 Conductive foam
● 10^3 to 10^10 Anti-static foam
Condutive foam can automatically release charge and it is more suitable for high electrostatic sensitive electronic products.
Due to the difference of the resistance value, conductive foam is less than the static electricity of anti-static foam.
Conductive foam and anti-static foam has following features:

Conductive foam and anti-static foam has following features:
Conductive foam (ESD FOAM)
● Raw materials: polyethylene (LDPE), conductive fillers and antistatic agents
● Production progress: Mixing master batchers – Extrusion – Radiation (cross linking) – High Temperature Foaming
● Features: Environmental protection | Easy to secondary molding processing | Waterproof | Permanent conductive or anti static
In this way, we can get the permanent conductive & antistatic foam (ESD FOAM) with smooth surface. The resistance of conductive foam is 10^3 Ω – 10^5 Ω.
Conductivity & anti-static performance is not affected by environmental humidity.
ESD foam is idely used in the following applications:
● LCD screen production
● Assembly Line mobile phones
● 3G terminals
● Computers
● Notebook computers
● Optoelectronic components
● PCB board workshop turnover
● Electronic products that are prone to static electricity during transportation
Anti-static foam is similar to a very large resistance, with extremely weak conductivity, theoretically tearing strength is better than conductive foam.
The resistance value of Anti-static foam and Conductive foam has a range:
● 10^3 to 10^5 Conductive foam
● 10^3 to 10^10 Anti-static foam
Conductive foam and anti-static foam are both belong to ESD FOAM. Due to the difference in resistance value, the static half-life of conductive foam is shorter than that of anti-static foam, and the static voltage of conductive foam is also much smaller than that of anti-static; but both can automatically release charges. Anti-static foam is to disperse the electric potential generated during product handling into the foam and further reduce the electrostatic hazard.
According to the breakdown voltage of different products and the working environment, the charge dissipation of anti-static foam is slower and more suitable for precision small strokes. For electronic products with high breakdown voltage, conductive foam has a faster charge dissipation, which is suitable for high breakdown voltage or needs to dissipate the charge faster.
