EMI / RFI / Microwave Absorbers

Absorber Plastic Grain (APG)

 

   

Absorber Plastic Grain (APG) is a special plastic grain, include absorbent material with high percentage. It’s suitable for injection molding to produce complex shape to get a good  performance to solve the EMI problem in wide band till 18GHz. We not only offer the grain, but also offer the injection molding OEM service.

Features : 

· Absorbent material inside plastic grain
· Suitable for injection molding application
· Suitable for complex shape design
· More thick with more absorption effect
· Recyclable
· RoHS Compliance
· For a product case, both sides can absorb EMI
· Not shielding material, with low electrical conductivity
· Good absorption performance in wide band (18GHz max.)
