If you’re stuck with plastic inner component issues for low-voltage electrical appliances—like failing flame retardancy tests, high-temperature deformation, or costly materials—JIELI’s modified engineering plastic solution is here to help. As a 25-year international enterprise integrating manufacturing, R&D, trade, and service, JIELI delivers materials that meet global safety standards while cutting overall costs by 15% to 30% .
1. Solve 3 Core Pain Points of Plastic Components
Flame Retardancy & Heat Compliance
Traditional plastics often struggle to meet UL94 V-0 flame retardancy and 960°C hot wire requirements. JIELI offers nitrogen-based, bromine-based, and red phosphorus flame-retardant modified PA/PPA materials, certified by GWFI/GWIT. These materials boost fire resistance efficiency by 30% and use halogen-free, eco-friendly formulas .
High-Temperature Stability & Strength
To fix high-temperature deformation and weak mechanical strength, JIELI uses enhanced PA46/PPS materials that withstand over 270°C (with HDT exceeding industry standards). Their tensile strength hits 500-760 N/mm², strong enough to replace metal components for lighter products .
Cost & Supply Chain Risks
JIELI’s modified plastics are 40% cheaper than imported special plastics. Plus, its 12,000-square-meter factory ensures stable production (10,000 tons annual capacity) and on-time delivery, eliminating supply chain worries .
2. Scenario-Specific Solutions for Key Electrical Products
MCB Miniature Circuit Breakers
