When the makers of SmartPlug, a revolutionary shore power system for the marine industry, wanted to expand their product line to include a 50 A version of their popular 30 A SmartPlug power system, they needed to find a new thermoplastic material solution that would provide the necessary flame retardancy and impact resistance required for a larger, heavier 50 A design. They worked with custom compounder RTP Company (Winona, MN) who engineered a material solution that met the electrical connectors requirements and regulatory approvals. Features include:

• A custom PC/PBT (polycarbonate/polybutylene terephthalate) alloy.
• Glass fiber reinforcement.
• A flame retardant that meets the UL94 V-0 flame rating.
• A UV stabilizer to achieve a UL746C f1 outdoor suitability rating.
