General

     HQS-1 is classic copper based compound and their synergists as high effective heat stabilizer package for polyamides

 

Applications

 Good fit with most non-filled, mineral filled, glass fiber reinforced, toughened, flame retardant, filament covering most polyamides

 

 Sustain long term thermal ageing at 150~180oC, for glass fiber reinforced polyamide 6 & polyamide 66

 

 Excellent suppressant for polyamide pellet yellowing

 

 Provide good mechnical properties retention under UV

 

 Light bluish color in polyamide pellets might develop when adsorbing moisture in air



Typical Physical Properties

    White powder.

  

   Non melting under most polyamide processing temperature l Partially soluble in water, thereof slight negative for CTI


  Inorganic halogen containing


    

Let down Ratio

 0.1 ~ 1.0 wt.% suits for most cases, or combined together with other polyamide stabilizer synergists.

 

 Recommended 0.3 wt.% dosage for glass reinforced PA66

 

 Recommended 0.1 wt.% dosage for melamine cyanurate flame retardant polyamide


Storage & Handling

 Avoiding moisture, heat, control exposure to open air

 

 Shelf life under seal >12 months

 

 To feed in the main port of twin screw extruder is most straight forward. The use of HQS-1 concentrate is feasible, but the low melting point polyamide carrier is recommended.
