HM-664

NUCLEATOR MASTERBATCH

HM-664 is an additive concentrate containing Milliken's Hyperform® HPN-210M nucleator. This masterbatch compound is designed to reduce cycle time in injection molded polyethylene parts, improve stiffness and HDT, and reduce or improve warpage challenges during processing.

Key Features:

• Designed to be added to injection molded polyethylene parts
• Improved stiffness, HDT and part uniformity
• Uniform concentration of additives in concentrate form.
• Masterbatch pellet form for ease of addition and feeding into extrusion equipment

Directions for Use:

• HM-664 is added to HDPE or LLDPE at 2.5% to 5% to achieve faster cooling, higher crystallization temperature and a higher crystallization rate. Parts are ejected from the mold with at a higher overall temperature but will have more completed crystal formation, allowing for a reduced overall cycle time.
• Note: Effectiveness is significantly reduced in LDPE due to the high long chain branching of the polymer. LDPE with MI > 25 can present some of the above performance improvements.

FDA Compliance:

• This product is not approved for use in food contact applications at this time, but will be updated once regulatory tests are completed.
