PA66 BASF A3HG6 Resin

Material Introduction: PA66 BASF A3HG6 (Germany BASF) is a high‑performance 30% glass‑fiber‑reinforced PA66 engineering plastic. It features high strength, high rigidity, excellent heat resistance and dimensional stability, together with good electrical‑insulation performance, HB‑grade flame retardancy, oil resistance and hydrolysis resistance. Its inherent water‑absorption property will affect dimensional stability and partial performances (large performance difference between dry and conditioned state); strict drying is mandatory before processing.

Main Applications

Automotive industry: Mainly for under‑hood automotive structural parts relying on high strength and heat resistance, e.g. cooling fans, door handles, fuel‑cap parts, intake grilles, radiator shrouds and lamp holders.

Electronic‑electrical industry: Electrical‑insulation components such as connectors, spools, timers, circuit‑breaker covers and switch housings.

Mechanical parts / Industrial fittings: Machinery & instrument components (chair seats, bicycle frames, ice‑skate shoe bases, textile shuttles, pedals, pulleys), oil tubes, fuel tanks and precision engineering articles.

Other fields: Sports‑leisure goods, home appliances, communication equipment and textile‑machinery parts.

Injection Molding Parameters

Processing Item	Recommended Range / Condition	Notes & Explanations
Drying Treatment	Hot‑air drying at 80 ℃ for 2‑4 h; alternatively 85 ℃ hot‑air drying. Vacuum‑dry at 105 ℃ for 12 h for opened packages or moisture＞0.2%.	Critical operation. Control moisture content ≤0.12%‑0.15% to avoid hydrolysis‑induced bubbles, silver streaks and mechanical‑property deterioration. Use immediately after drying or seal and keep warm properly.
Melt Temperature	275‑280 ℃ for glass‑filled grades; alternative 280‑305 ℃.	Fine‑tune according to equipment and part geometry. Avoid temperature＞300 ℃ or long residence‑time to prevent material degradation.
Mold Temperature	Recommended 80 ℃; optional 80‑90 ℃. Mold temperature affects crystallinity and physical properties. Thin‑wall parts molded below 40 ℃ require annealing for geometric stability due to time‑dependent crystallinity change.	Higher mold temperature delivers better crystallinity and property stability.
Injection Pressure	750‑1250 bar.	Adjust per product & mold design.
Injection Speed	High‑speed injection (moderately reduced for reinforced grades).	Fast filling is beneficial; mold shall be well‑ventilated.
Runner & Gate	Gate bore ≥0.5*t (t = part wall thickness). Hot‑runner gate size shall be smaller than conventional runner. Minimum diameter for submarine gate:0.75 mm.	Nylon solidifies rapidly; gate location and size are critical for filling.
Back Pressure	‑	‑
Screw Speed	‑	Avoid excessive shear heat generation.
