Modification by Hi-WAX™ (PC/GF)

PC:: Melt Volume Rate(MVR):11㎤/10 min(300°C,1.2kg), Density:1,200kg/㎥
GF:: Chopped Fiber(Fiber Length:3mm, Fiber Diameter:13μm)
Additive:: Hi-WAX™ 1105A … Moleculer weight: 1,500, Density:940kg/㎥ Acid Value:60mgKOH/g

After Charpy Impact Test Sample Appearance

It is presumed that the addition of 1105A promotes void formation at the resin/GF interface during impact testing, thereby improving impact resistance.

Polyamide (PA)/Glass Fiber Compound

Release Property Modification (Hi-WAX™ addition improves mold release and stabilizes color tone)

[Formulation]: PA6/GF =70/30wt%, Additives: 0.5phr
[Molding]: Twin-screw Extruder (25mmφ, Cylinder Temperature 240°C)
Injection Molding (Cylinder Temperature 250°C, Mold Temperature 80°C)
[Recommended Grades]: Hi-WAX™ 200P, 400P, 800P, 405MP

Compared to montan acid ester, Hi-WAX™ has inferior mold release properties but superior mechanical strength.
