– PolyOne GLS Thermoplastic Elastomers today announced the launch of an overmolding technology based on Versaflex™ VDT thermoplastic elastomer (TPEs), developed for vibration and impact damping applications.
Customers familiar with our Versaflex VDT material have asked for an overmolding variation that allows them to leverage the design freedom of two-shot and insert injection molding,” said Charles Page, director, global marketing, PolyOne GLS Thermoplastic Elastomers.
Versaflex VDT overmolding grades deliver the same great vibration and impact damping performance as the original Versaflex VDT technology, exceeding most thermoset solutions while offering the advantage of thermoplastic design flexibility.

Cesa™ Fiber Additives for stain resistance efficacy
are non-fluorine additive concentrates developed
for incorporation in the yarn during extrusion.
They
provide durable and efficient stain release properties
to polyester fibers making it easier to remove stains
with common household cleaners.
APPLICATIONS
Cesa stain-resistant solutions are suitable for
polyester fibers used in automotive textiles, home
and office furnishings, and carpets and rugs.

Follow up by purging machine with general
purpose PP
• Residence time should not exceed 5 minutes for Maxxam FR products
• General ventilation is suggested
Shut Down
• Purge the equipment with a general purpose PP
• All tooling and equipment must be free of any residual Maxxam FR upon
shut down
• Continue generating parts made from the natural PP until clear
• Wipe down tool steel with mold cleaner
• When using a hot runner system, care must be taken to remove residual
product from the manifold
MOLD DESIGN RECOMMENDATIONS
Cold Slug Wells
• Place cold slug wells at the base of the sprue to capture the cold material first
emerging from the nozzle
• Place cold slug wells at every 90° bend in the runner system
• Well depths approximately 2–3 times the diameter of the runner provide best
results
Draft Angle • Draft angle should be 1/2°–1° per side.
Vents should be placed at the intersection of each 90° bend in the runner
system off of the cold slug well and vented to atmosphere
Black Specks
Contamination
• Purge barrel with general purpose PP
• Verify correct nozzle is being used
• Pull screw for cleaning
Degraded/overheated
material
• Decrease melt temperature
• Decrease injection speed
• Use appropriately sized barrel
Brittleness
Degraded/overheated material
• Decrease melt temperature
• Decrease injection speed
• Use appropriately sized barrel
Gate location and/or size
• Relocate gate to nonstress area
• Increase gate size to allow higher flow rate and
lower molded-in stress
