As a specialized manufacturer of high-performance engineering plastics, Shanghai Yunshan Plasticizing Co., Ltd. is proud to introduce our PA66 21SPC Flame Retardant Compound. Engineered in our Shanghai facility, this halogen-free, mineral-filled Polyamide 66 material is designed to meet the stringent safety and performance demands of modern electrical and electronic components. We understand that reliability is non-negotiable in your applications, which is why our compound delivers a consistent UL94 V0 flame retardant rating while maintaining excellent mechanical and electrical properties. It represents our commitment to providing safe, durable, and process-efficient material solutions for the global market.
This advanced compound is formulated to address critical challenges in applications where fire safety, dimensional stability, and reliable performance under electrical stress are paramount. Below, we detail its key characteristics and benefits.
- Superior Flame Retardancy & Safety: The material achieves a UL94 V0 rating at a thin wall thickness of 0.8mm, providing a high level of fire safety for end products. Its halogen-free, phosphorus-based flame retardant system ensures it does not release corrosive or toxic gases during combustion, making it an environmentally and user-friendly choice for indoor electronic equipment.
- Enhanced Electrical Properties: A standout feature is its high Comparative Tracking Index (CTI), which indicates superior resistance to electrical surface tracking. This property is crucial for components like connectors, circuit breakers, and switches that operate in humid or contaminated environments, significantly reducing the risk of electrical failure.
- Excellent Dimensional Stability & Low Warpage: The incorporation of 21% mineral filler (SPC) greatly reduces molding shrinkage and minimizes part warpage. This ensures that complex, thin-walled components maintain their precise shape and dimensions after molding and during use, which is vital for assembly and long-term reliability.
- Good Mechanical Strength & Stiffness: While offering flame retardancy, the compound retains good tensile strength and high stiffness from the PA66 base and mineral reinforcement. This provides the structural integrity needed for housings, brackets, and other load-bearing parts in electrical assemblies.
- Excellent Processability: Designed for trouble-free injection molding, it offers a wide processing window, good flow characteristics, and fast cycle times. This translates to higher productivity, lower rejection rates, and overall cost efficiency in your manufacturing process.
- Heat Resistance & Good Gloss: It maintains good performance at elevated temperatures encountered in electrical applications. Additionally, it can produce parts with a good surface finish, which is often desirable for visible components.
Here is a summary of typical properties for our PA66 21SPC Flame Retardant Compound:

Frequently Asked Questions (FAQ)
Q1: What does "21SPC" mean in the product name?
A1: "21SPC" indicates that the compound is filled with 21% mineral filler, specifically a special mineral combination. This filler enhances dimensional stability, reduces warpage, and improves the flame retardant performance while maintaining good processability.
Q2: Is this material suitable for food contact or medical applications?
A2: No. This is a standard flame retardant grade designed primarily for electrical and electronic applications. It is not formulated or certified for food contact or medical use. For such specialized requirements, please contact our technical team to discuss custom solutions.
Q3: Can you provide material with different colors?
A3: Yes. While the standard color is natural (off-white), we can provide custom colors upon request. Color masterbatches can be added during our compounding process to meet specific aesthetic requirements for your end products.
Q4: How should this material be dried before processing?
A4: Like all polyamides, this compound is hygroscopic. We recommend drying at 80-90°C for 4-6 hours in a dehumidifying hopper dryer to achieve a moisture content below 0.15% before injection molding. Proper drying is essential to prevent surface defects and maintain mechanical properties.
Q5: What is the typical mold temperature for processing this grade?
A5: A mold temperature in the range of 70-90°C is recommended. This helps achieve a good surface finish, optimize crystallinity for dimensional stability, and reduce molded-in stresses.
Q6: Do you offer technical data sheets (TDS) and samples for testing?
A6: Absolutely. We provide comprehensive Technical Data Sheets detailing all physical, mechanical, thermal, and electrical properties. We also offer sample quantities for your in-house testing and mold trials to validate performance in your specific application.
Q7: What is the lead time for an order?
A7: For standard grades, the typical lead time is 7-15 days after order confirmation. For large-volume orders or custom formulations, the lead time can be discussed and confirmed based on the specific requirements.
Q8: How is the material packaged?
A8: The compound is packaged in 25 kg moisture-proof bags with an inner polyethylene liner to ensure the material remains dry during storage and transportation.
Choosing the right material is a critical decision for the safety and performance of your products. At Shanghai Yunshan Plasticizing, we combine our technical expertise with a customer-focused approach to deliver reliable material solutions.
