Core Products of Konlida
1. Conductive Foam
-
Standard Conductive Foam: PU or PORON foam wrapped with conductive fabric, ideal for antenna and chassis sealing.
-
SMT Conductive Foam: Surface-mountable on PCBs for grounding or antenna connections, compatible with reflow soldering.
-
AIR LOOP Conductive Foam: Innovative D-shaped structure, lightweight and thin, internal wiring possible, widely used in Apple products.
-
Omnidirectional Conductive Foam: Fully metal-plated, providing excellent 3D shielding at low cost.
2. Beryllium Copper Contacts
High elasticity, corrosion-resistant, non-magnetic, ideal for shield contact points.
3. Conductive Rubber
Silver or nickel particles evenly embedded in silicone, offering sealing and EMI shielding for military and high-end electronics.
4. Absorber Materials
Electromagnetic wave absorption to prevent interference, suitable for high-frequency applications like 5G and ADAS chips.
5. Thermal Management Materials
Includes thermal silicone pads, graphite sheets, aerogel insulation films, and graphite-copper composites for efficient heat dissipation.
