PA66 Toray CM3004‑V0 Resin

Material Introduction: PA66 Toray CM3004‑V0 (Japan Toray) is a halogen‑free flame‑retardant, unreinforced injection‑molding PA66 resin. Its core advantages are outstanding halogen‑free UL94 V‑0 flame retardancy, good electrical insulation, heat resistance and mechanical strength, while retaining favorable processing flowability of PA66. Its inherent water‑absorption property will affect dimensional stability and partial performances; strict drying is mandatory before processing.

Main Applications

Electronic‑electrical industry: Parts with high requirements for flame retardancy and electrical insulation, such as electrical appliance housings, electrical components, connectors, switch bases, sockets, joints, coil bobbins, timers and circuit‑breaker covers.

Automotive industry: Automotive interior and structural components.

Other fields: Aerospace interior & structural parts, electrical components, food‑grade applications (subject to relevant certifications).

Injection Molding Parameters

Processing Item	Recommended Range / Condition	Notes & Explanations
Drying Treatment	Hot‑air drying:80‑85 ℃ for 2‑4 h; extend drying time or adopt vacuum drying under high‑humidity environment (>50% RH); target moisture content＜0.2%	Critical operation. Prevent hydrolysis‑induced bubbles, silver streaks and mechanical‑property loss. Use immediately after drying or seal and keep warm properly.
Barrel Temperature	Rear zone: approx.299 ℃; middle & front zone adjusted according to equipment and part geometry	Higher rear‑zone temperature improves screw retraction speed, reduces wear from unmelted particles and lowers torque load.
Melt Temperature	260‑290 ℃	Fine‑tune per equipment and part geometry. Avoid temperature＞300 ℃ or long residence‑time to prevent material degradation.
Nozzle Temperature	260‑277 ℃; raise temperature for cold mold to avoid nozzle freeze‑off.	‑
Mold Temperature	80‑120 ℃ (99‑121 ℃ recommended)	Higher mold temperature delivers good surface appearance and melt filling. CM3004‑V0 solidifies rapidly and is easy for ejection even at high mold temperature.
Injection Pressure	Higher than unreinforced PA66 grade	Adjust according to product shape, gate and mold temperature.
Injection Speed	Fast injection	Fast filling avoids surface defects caused by premature solidification.
Back Pressure	Not recommended	Back pressure may degrade physical‑mechanical performances.
Screw Speed	‑	‑
Runner & Gate	‑	‑
Molding Cycle	Approx.10‑30% shorter than unreinforced PA66	‑
Mold Release	Good, mold release agent generally unnecessary; if needed, use 0.05‑0.10% aluminum distearate.	‑
