Claude Bamberger Molding Compounds Corp.: BAMBERKO ULTIMAX
Purging Compound:
Hi-molecular Ultimax is formulated to purge all types of
engineering and thermoplastic materials.
It will not damage or scratch injection cylinders and extrusion
barrels.
It is recommended for use in swift color or resin changeovers
and to clean equipment of carbonized residue
Ultimax will not melt completely, and is designed to purge hi-heat
and high temperature engineering plastics and other difficult purging
jobs.
While most purging compounds work best in a 350-450F (176 to 230
Celsius) range, Ultimax is designed for use in purging high heat
engineering plastics in the 450-525F (230 to 275 Celsius) range.
Compared to other purge compounds, Ultimax will clean equipment
more quickly and more efficiently in a considerable saving of a
manufacturer’s ‘downtime’. In most instances it will work without
the need to change temperatures.
Produced from prime resin, Ultimax is recommended for use in FDA
approved food contact items
as well as for manufacturing medical products
Ultimax minimizes unpleasant odors and fumes, making it
environmentally friendly.

Buckman Laboratories, Inc.: Successful Applications of BUSAN
11-M1 in Plastic and Rubber Compounds:
Busan 11-M1 is a multifunctional barium metaborate pigment used as a
fire retardant, fungus inhibitor, and UV light stabilizer in polyvinyl
chloride and other plastic and rubber compounds. Typical of PVC
products compounded with Busan 11-M1 are automotive tops and trims,
inflatable buildings, pond liners, roofing, and plastic-coated fabrics
such as tarpaulins and awnings.
The effectiveness of Busan 11-M1 as a fire retardant is restricted
to polymers containing a halogen donor or to which one can be combined.
Bromine compounds are somewhat more effective than other halogens but
chlorinated paraffin and chlorindic anhydride have performed very well.
Experience has indicated that Busan 11-M1 can replace antimony
trioxide in most fire retardant formulations. Subject to the degree of
halogenation and the degree of fire resistance required. Replacement
can be 50 to 100%.
In addition to providing after-flame resistance, Busan 11-M1 also
reduces the time of afterglow (i.e., flameless combustion) and in many
formulations reduces the amount of smoke generation. Other advantages
over antimony trioxide are the low refractive index of Busan 11-M1
which prevents interference in tint and dye requirements and the
fungicidal activity that characterizes barium metaborate.
Busan 11-M1 is well known as a fungicide for coatings and plastics.
Its advantages in plastics and plastic-coated fabrics over conventional
organic fungicides are longevity in the film and efficacy unaffected by
UV exposure. Products particularly susceptible by fungal disfigurement
and/or deterioration include pond liners, tarpaulins, awnings, and
shower curtains.
Busan 11-M1 provides UV light stabilization to most polymeric

materials including PVC and glass-reinforced polyester. Its durability
in these materials is outstanding and thus extends the performance of
UV absorbers.

BYK-Chemie USA: Air Release Additives for Ambient Cure
Polyester
Resins:
Undesired air inclusions are formed during resin manufacture and
subsequent processing into finished parts of coatings.
They restrict processability because they cause stable foam during
filling and application.
They reduce the quality of the finished parts.
Air inclusions:
* lower the chemical resistance
* cause optical defects
* reduce the physical properties
Therefore: Air Release Additives should be a fixed component of
every quality tuned polyester resin formulation.

Danisco Cultor USA, Inc.: Recommended Glycerol Ester Based
Additives for Polyolefins:
Danisco Cultor offers the following glycerol ester based plastics
additives for various polypropylene and polyethylene application areas:
DIMODAN PVK:
Is a distilled monoglyceride (minimum monoester content in excess of
90%) made from edible, fully hydrogenated vegetable oil. It is used as
a mold release agent, processing aid, dispersing aid, and/or antistat
in polyolefins. Dimodan PVK is also used as a lubricant in plastics
extrusion and for surface modification of pigments and fillers.
Dimodan PM:
Is a distilled monoglyceride (minimum monoester content in excess of
90%) made from edible, fully hydrogenated lard or tallow. It too may be
used as an antistat, mold release agent, dispersing aid and/or
processing aid in polyolefins, or as a lubricant in extrusion. Dimodan
PM is also used for surface modification of fillers and pigments.
Dimodan PM PEL:
Is a pellet form of Dimodan PM. It is particularly attractive to
many polymer producers and processors who favor this product form's
handling characteristics over those of beaded or powdered materials.

Dimodan ML 90:
This product functions as a good mold release agent with immediate
antistat effect and improved mold release properties, over distilled
glycerol monostearate (GMS), in injection molding applications.
Dimodan MB 90:
Features lower volatility during polymer processing when compared to
conventional GMS. Therefore, Dimodan MB 90 brings advantages to a
number of high temperature processing applicatons; such as fiber
extrusion, thermoforming and BOPP film.
Dimodan MO 90:
Is an effective antifog agent in various LDPE and EVA copolymer
polyethylene food packaging applications. It will also work as a
wetting agent in LDPE films.

Danisco Cultor USA, Inc.: Recommended Glycerol Ester Based
Additives for Polyolefins (Continued):
DIMODAN PML 70:
Is a newly designed and engineered glycerol ester. Developmental
work has demonstrated Dimodan PML 70 to be an extremely effective
antistatic agent in injection molded block (impact) copolymer PP and
injection molded HDPE applications.
GRINDSTED PS 101:
Is a triglyceride (GTS). Danisco Cultor recommends PS 101 as an
external lubricant which can be used to conserve energy during the
extrusion of reactor grade PP.
Grindsted PS 414:
Is yet another performance tailored new product from Danisco. It
functions as a good antistat for LDPE and LLDPE films. PS 414 performs
well in comparison to the ethoxylated amines and amide type antistats

which have FDA restrictions on their use in food contact applications.
Since all of the components of Grindsted PS 414 are fully FDA
sanctioned for use in LDPE and LLDPE, it should be considered by the
formulator for applications needing FDA clearance and excellent
antistatic functionality.

134 Plastics Additives

Specialty Products Co.: STYRID Styrene Suppressant Additive:
Styrid is a styrene suppressant with a unique chemical formulation.
Tests have proven that Styrid provides suppression rates in excess of
50% with no effect upon interlaminar bonding.
Appearance: White translucent semi-liquid at room temperature
Physical Data:
Specific gravity: (H2O=1): <1
Weight: 7.40-7.55 lbs/gal
Flash point: 100F
Laminate bonding: (ASTM D2344)
Effects:
Styrid, when used properly in polyester resin, will reduce styrene
emissions to conform to California Rule 1162 without causing
delamination or secondary bonding problems.
Application:
To be used at room temperature at 0.6% to 1% by weight. Normal
mixing procedures will disperse material completely. Agitation is
required prior to use to assure proper consistency.
Advantages:
* Reduces styrene emissions by 50% or higher
* Has no effect on interlaminar bonding
* Liquid form for easy handling
* Reduces styrene odor
* Material is used as supplied at ambient room temperature (no
heating or pre-diluting with solvents required).
Styrene Suppressant Additives:
These additives are materials that are currently available to the
composite fabricator. They are most effective when using the open-
molding processes and, when properly used, can reduce styrene emissions

during the curing stage of the composite. Styrene suppressant additives
such as Styrid are substances which, when added at a prescribed
concentration to either unsaturated polyester, vinyl ester, or DCPD
resins, will reduce the amount of styrene vapors escaping from the
composites. They are effective primarily for open-molding processes
during the curing stage of the composite. Current styrene suppressant
formulations, in addition to the wax they contain, also have components
which allow bonding between laminates while effectively reducing the
amount of styrene vapor emitted as the composite cures. Styrene
suppressant additives are supplied in either semi-liquid or solid form.
They can be used as supplied, or diluted in organic solvents. Some
require heating to make them flow before mixing into the resin while
others, such as Styrid, do not. They are incorporated directly into the
resin before it is catalyzed. The treated resin can be used immediately
or kept in storage for further use.
