Envalior Durethan AKV 30 H3.0 PA66 Resin

Physical Properties

• Bulk Density: Per ISO 60, the bulk density is 0.700 g/cc (0.0253 lb/in³), representing the material’s density in loose particulate form before molding.
• Density: According to ISO 1183, density is 1.36 g/cc (0.0491 lb/in³), identical to H2.0 but with enhanced heat-aging stability.
• Moisture Absorption at Equilibrium: At 50% RH per ISO 62, moisture absorption is 1.9 %, a marginal reduction from H2.0 due to formulation tweaks.
• Water Absorption Saturation: Per ISO 62, water absorption is 5.5 %, consistent with other 30% glass-filled grades.
• Linear Mold Shrinkage (Flow): At 290°C/80°C per ISO 294-4, flow shrinkage is 0.0040 cm/cm (0.0040 in/in), nearly identical to H2.0.
• Linear Mold Shrinkage (Transverse): At 290°C/80°C per ISO 294-4, transverse shrinkage is 0.011 cm/cm (0.011 in/in), slightly higher than H2.0 due to processing differences.

Polymer Properties:

Applications:

The combination of extreme thermal stability and high mechanical strength makes Durethan AKV 30 H3.0 ideal for mission-critical parts.

1. Automotive Industry: This grade is specifically engineered for engine and transmission components that are exposed to high temperatures and aggressive fluids like oils and coolants.
   • Examples include air intake manifolds, engine mounts, thermostat housings, and radiator end tanks. Its ability to withstand thermal cycling and high-pressure loads is essential for these parts.
2. Mechanical Engineering: Its high stiffness and resistance to creep make it perfect for structural components, gears, and bearing cages that operate under continuous stress and high temperatures.
3. Electrical and Electronic Components: The material’s high dimensional stability and electrical insulation properties are used for switchgear, coil formers, and high-power connector housings where heat is a constant factor.
