HO-1506 ( Nucleating & Clarifier for PE )

Technical Data Sheet.
Thermoplastic compositions must exhibit certain physical characteristics to facilitate
widespread use. Specifically within polyolefins. For example uniformity in arrangement of
crystals upon crystallization is sometimes necessary to provide an effective, durable and
versatile polyolefins articles. To achieve desirable physical properties HO-1506 can be
employed to provide nucleation sites for polyolefins crystal growth during molding or
fabrication. Nucleating agents are known to modify the crystalline structure of
thermoplastic polymers.

Advantage of HO-1506

• HO-1506 increase the temperature and the rate of crystallization, thus crystallize at
  a much faster rate than non-nucleated polyolefines.
• Crystallization at higher temperature results in reduced fabrication cycle times
  and variety of improvements in physical properties such as stiffness.
• HO-1506 provide nucleation sites for crystal growth during cooling of a thermoplastic
  molten formulation. Due to HO-1506 results in a larger number of smaller crystals.
  Smaller crystals formed therein clarification of the thermoplastic may be achieved.
• HO-1506 Improve modulus & stiffness.
• HO-1506 Improve optical properties without the loss of other physical properties.

HO-1506 in LLDPE

To a common Linear Low Density Polyethylene

(LLDPE) in the film industry and having a density of 0.917 grams per cubic centimeter, a
mixture of 1000 ppm of the following HO-1506 compound was applied:

The above compound and a standard stabilization package (500 ppm lrganox® 1010, 1000
ppm lrgafos 168, and 800 ppm zinc stearate) were also added to the formulation. The resulting
mixture was physically blended, twin screw compounded, and pelletized. The resultant
compounded resin was then made into film of 25 micron in thickness using a standard blown
film process with a blow up ratio of 2.5. The resultant film had the following properties:

HO-1506 in Various Types of Polyethylene

To several types of polyethylene (PEs), a mixture of 1000 ppm of HO-1506 and a standard stabilization package (500 ppm Irganox® 1010, 1000ppm lrgafos®168, and 800 ppm zinc stearate) were added. The resulting mixtures were
physically blended, single screw compounded, and pelletized. The resultant compounded
resin was then made into film of approximately 50 micron in thickness using a standard blown
film process with a blow up ratio of approximately 2.0. The resultant films had the following
optical properties:
