Reliable Material for Electrical Protection Parts
Red Phosphorus Flame Retardant Nylon is a reinforced nylon material developed for electrical protection components. The typical grade is PA 123AG6 FR. It uses a red phosphorus flame-retardant system and reaches a UL-94 V-0 flame-retardant rating.
The material also provides a Comparative Tracking Index (CTI) above 500V. This makes it suitable for molded parts that require a combination of flame resistance, electrical performance, and structural strength. Typical applications include circuit breakers, residual current protection devices, and related electrical components.
Compared with standard nylon materials, this grade is more suitable for applications where insulation reliability and mechanical load must be considered together.
High Strength and Rigidity for Structural Components
PA 123AG6 FR has a typical density of 1.52 g/cm³ and a molding shrinkage rate of 0.25%–0.35%. The controlled shrinkage range helps manage dimensional variation during injection molding, especially for housings, supports, and internal structural parts that need stable assembly dimensions.
The material has a tensile strength at break of 138 MPa and a flexural strength of 175 MPa. Its flexural modulus reaches 7100 MPa, giving molded components good rigidity and resistance to deformation.
The elongation at break is 3%, while the notched Izod impact strength is 9 kJ/m². This performance profile makes Red Phosphorus Flame Retardant Nylon particularly suitable for relatively stable electrical structures where high strength and stiffness are important purchasing considerations.
Material Selection for Electrical Injection Molding
When selecting this material for volume production, buyers should confirm the required flame-retardant level, CTI value, mechanical strength, molded dimensions, and injection molding conditions.
Circuit breaker components often require stable dimensions for housings, mounting areas, and internal supporting structures. The material therefore needs to match not only the electrical requirements of the finished product but also the mold design and actual processing conditions.
Providing information about the part structure, existing material, target mechanical properties, and molding equipment can help improve grade selection efficiency. Technical communication can also focus on reducing problems caused by mismatches between the material, mold, and injection parameters.
Production Control and Technical Support
Changshu Diyou New Material Technology Co., Ltd. has long-term experience in modified engineering plastics, with technical and production management experience tracing back to 1979.
For red phosphorus flame-retardant reinforced nylon, the company can manage the process from raw material handling and formulation design to twin-screw extrusion modification and product performance testing. The technical team can also support material selection and injection molding process matching according to the structure and performance requirements of electrical components.
Production, inspection, purchasing, and finished-product management are carried out under an ISO 9001 quality management system. Traceability information is maintained through relevant quality control processes. For customers with stable purchasing requirements, technical support can cover target performance, processing conditions, sample trials, and subsequent application issues.
