Semi-conducting Semi-conducting Semi-conducting PVDF-HFP Balls from Goodfellow are made from polyvinylidene fluoride-co-hexafluoropropylene (PVDF-HFP), a semi-crystalline fluoropolymer with useful semiconducting properties. The balls come in 4 quantities. Their high dielectric strength, chemical resistance, and thermal stability make them ideal for use as insulating spacers in electrical devices. The balls' semi-conductivity also allows them to act as charge dissipaters in electronics packaging. With their versatile properties, these PVDF-HFP balls have promising applications across electronics and electrical engineering.
