The company tried several TPE grades, hoping to find a material that would eliminate the adhesion problem while providing comparable softness to silicone.
The manufacturer worked with Avient to formulate a custom Versaflex™ TPE that featured a low durometer with excellent resistance to adhesion (sticking).
Armed with a new specialty TPE solution, the medical manufacturer handled gasket adhesion with a material that outperformed that not only silicone, but also conventional TPEs.

PRODUCTS APPLICATIONS DESCRIPTION/BENEFITS
EXCELITE PF-1 PVC sheet for digital print or trimboard;
Fine cell structure able to target low density:
improves consistency and control over
foaming process
FOAM ADDITIVE-54 PVC sheet for digital print or trimboard;
Finer cell structure than PF-1 promotes ultra
smooth surface finish; improves consistency
and control over foaming process
PF-1E & FA-54E
ADDITIVES
PVC sheet for digital print or trimboard;
Enhanced run time formulation reduces
die lip build-up in PVC processes, leading
to longer production run times
FOAM ADDITIVE-33 CaZN formulations for PVC sheet,
profile, or trimboard
Promotes finer cell structure,
higher cell density, and surface
quality in CaZN PVC dryblends
FOAM ADDITIVE-77 HDPE sheet & plastic lumber
Industry-leading cell structure and cell
density; achieves lower density without
sacrificing quality; self-nucleating and able
to increase extruder output rates up to 15%
FOAM ADDITIVE-85
Endothermic foam or
nucleating additive for olefin and
styrene polymers; plastic lumber,
sheet applications and
food packaging products
Can be used as a CFA or nucleating additive;
nucleating capabilities promote fine cell
structure and high cell density; achieves
greater density reductions with more
consistency and control
FOAM ADDITIVE-37 HDPE sheet & plastic lumber
Good cell structure and cell density
in HDPE lumber; greater consistency
and control over foaming process
EXCELITE CAN IMPROVE PRODUCTION EFFICIENCY
• The process operator has full control of density
• Minimizes product rejection due to unnecessarily high/low density
• Production should consistently target the bottom of the density specification
• Enables control over the reintroduction of regrind or reprocessed materials as a feedstock
• Enables the consistent foaming of products using higher percentages of regrind
• Carrier selection can promote longer run times, enabling increased line productivity through
less plate-out or material build-up on die lips
EXCELITE CAN IMPROVE SURFACE FINISH
Excelite additives creates a fine, consistent cell structure within the extruded polymer, which determine
the surface roughness.
EXCELITE VS POWDER
• Enables a greater level of density control, through
consistent distribution in the polymer
• Simplifies and optimizes resin compounding
capabilities (PVC dry blends)
• Enables greater control over foaming and expands
processing window when re-introducing regrind
• Clean and highly accurate dosing process, with
fewer of the health and safety concerns that can
become apparent with powder CFAs
EXCELITE VS PELLET
• Being significantly more concentrated, Excelite additive enables lower total cost to foam
• Can achieve lower density, less carrier influence
• Finer and tighter cell structure through better additive distribution
• Improved linear consistency of cell structure as ColorMatrix pumps continually meter output,
giving greater stability over material dosing
• Improved plant working capital as lower let down ratios means less material is consumed and
reduces inventory holdings
TECHNICAL SUPPORT
• Avient has a market leading service team which understands
foaming processes, we assist customers to deliver performance
and production efficiencies with Excelite™ technology
