Applications
Atmer 7749 is a 75% concentrate in PE for use as a flame retardant in PE.

Mode of action
Atmer 7749 is a combination of chemicals dispersed in PE. Using a concentrate gives better dispersion and overcomes complications that can be encountered when using additives in their natural physical forms.

Benefits

• Effective dosing of difficult materials

• Better distribution of additives in the base polymer

• Visible reduction in fuming/smoking

• Improved printing and sealing properties in film and sheet products

Recommended Polymers

• LDPE/LLDPE

• HDPE

• PP

Guidelines for use
Atmer 7749 is incorporated into the polymer during processing. Experience has shown that simple manual mixing will normally give an acceptable dispersion, though mechanical means are preferred.
Typical addition levels are 3.5 - 4.5% in injection moulding and sheet extrusion.
