PA66 | 35% Glass Fiber Reinforced | Red Phosphorous FR | Heat Stabilized | Injection Molding | Black

🛡️ TECHNYL PROTECT A 20 V35 BK 25 is a polyamide 66 grade reinforced with 35% glass fiber, based on a Red Phosphorous flame retardant system, heat stabilized, designed for injection molding. This grade provides robust UL94 V0 and a full UL Yellow Card while offering good mechanical properties. This grade is suitable for molding insulating parts for electrical devices, and more generally for thin parts under stress. This grade was formerly known as TECHNYL A 20 V35 BLACK 25.

🔑 Key Features Overview ✅ Red Phosphorous Flame Retardant ✅ UL94 V0 (0.75mm / 1.5mm / 3.0mm) — Full Thickness Certification ✅ Full UL Yellow Card (QMF22.E44716) ✅ Halogen Free Flame Retardant ✅ 35% Glass Fiber Reinforced — High Rigidity ✅ Heat-Aging Stabilized — Long-Term Service Reliability ✅ Suitable for Thin-Wall Stress Parts

📊 Mechanical Properties Analysis • High Rigidity: Dry tensile modulus of 12500 MPa, flexural modulus of 11000 MPa, and flexural strength of 260 MPa provide excellent structural load-bearing capacity. • Thin-Wall Part Suitability: 35% glass fiber reinforcement provides excellent rigidity and dimensional stability for thin-wall stressed components. • Good Impact Resistance: Dry Charpy notched impact of 10 kJ/m², increasing to 12 kJ/m² after conditioning. • Improved Toughness After Conditioning: Strain at break increases from 2.1% to 3.2%.

🔥 Red Phosphorous Flame Retardant Technology • High Efficiency: Red phosphorous FR system achieves UL94 V0 rating at low addition levels, minimizing impact on mechanical properties. • Halogen Free: Meets halogen-free requirements with low smoke and low corrosive gas emissions during combustion. • Good Electrical Properties: Maintains excellent insulation resistance and arc resistance. • Processing Note: Strict process control is required to prevent thermal degradation and gas evolution.

Drying Conditions: • Drying Temperature/Time: 80°C • Suggested Max Moisture: 0.2% Injection Temperatures: • Rear Zone: 265 – 275°C • Middle Zone: 270 – 280°C • Front Zone: 280 – 290°C Recommended Mold Temperature: • 60 – 90°C (up to 120°C for high surface quality requirements)

⚠️ Special Processing Notes for Red Phosphorous FR Materials • Prevent Thermal Degradation: Melt temperature should not exceed 295°C, residence time < 8 minutes. • Mold Venting: Ensure adequate mold venting to avoid gas marks and burn marks. • Equipment Material: Use steel with high chromium and high carbon content (minimum 16% chromium). • Shutdown Procedure: Before prolonged shutdown, purge the barrel with low-corrosion materials such as PP or PE.
