Halogen-Free Flame-Retardant PC for Electrical Housings
Flame Retardant Polycarbonate Compound is a modified PC material using a halogen-free flame-retardant system. It combines flame resistance, heat resistance, and impact performance for injection-molded electrical housings.
Typical applications include charger housings and charging pile housings. The material can also be considered for other electrical accessories where flame-retardant protection and resistance to impact are required.
PC is suitable for housing components that require structural strength and molded appearance. With flame-retardant modification, the material can additionally meet the stated UL-94 V-0 requirement.
Strength, Impact Resistance and Heat Performance
The typical grade is PC 302FR. It has a density of 1.20 g/cm³ and a molding shrinkage range of 0.50%–0.70%.
Tensile strength at break is 70 MPa, while elongation at break reaches 100%. Flexural strength is 90 MPa and flexural modulus is 2300 MPa.
The notched Izod impact strength is 60 kJ/m², providing useful impact absorption for molded housings and electrical structural parts.
Its heat deflection temperature is 120°C, and the flame-retardant rating reaches UL-94 V-0.
This combination allows Flame Retardant Polycarbonate Compound to address flame resistance, heat performance, structural strength, and impact resistance within one PC material system.
Housing Design Influences Molding Performance
Charger and charging pile housings can include snap-fits, screw bosses, ventilation openings, ribs, and large visible surfaces.
For these structures, material purchasing should consider more than the V-0 rating. Melt flow, shrinkage, impact performance, wall thickness, and the mold structure can all affect finished-part quality.
Different colors, wall thicknesses, and mold designs may influence the appearance and processing condition of the molded component. Before batch purchasing, buyers can provide drawings, dimensions, wall thickness, working temperature, and flame-retardant requirements.
Trial molding can then be used to check filling behavior, shrinkage, cracking, surface quality, and assembly performance. For components exposed to heat for extended periods, the listed 120°C heat deflection temperature should also be compared with actual service conditions.
Support for Flame-Retardant PC Processing
Diyou New Material can provide technical support from modified material formulation and twin-screw extrusion to injection molding verification.
For flame-retardant PC, the technical team can evaluate halogen-free flame-retardant requirements together with mechanical properties, flow behavior, and molded-part structure.
Support can also include analysis of cracking, incomplete filling, and dimensional problems found during injection molding.
Research and development, purchasing, manufacturing, inspection, and after-sales processes are managed under an ISO 9001 quality management system. This provides traceability for flame-retardant performance, mechanical parameters, and production batches.
For customers selecting Flame Retardant Polycarbonate Compound, this production and technical structure helps connect material data with actual charger or electrical housing molding requirements.
