• Good abrasion resistance
• Excellent chemical resistance
• Nice surface finish
• Good bonding with flame retardant PC/ABS
• Provided a rubbery touch feel, chemical
resistance (including to ethanediol), and better
appearance than the incumbent TPV solution
• Eliminated a secondary process through two-
shot injection molding with good adhesion to
PC, ABS, PC/ABS, and copolyester handles
• Offered quick technical support to accelerate
the product development

In addition, several blends of the above polymers such as
PC/ABS, PC/PETG, PC/PBT and PPO/PS have great commercial importance for several applications.
Optimal adhesion values are also obtained for
overmolds onto PC (Lexan), ABS (Cycoloy), PC/ABS(Cycolac) and PC/PBT (Xenoy) as demonstrated in Figure
5.
