For example, a TPE that can bond to PC does not bond to PP, vice versa. The failure mode is cohesive on PP and adhesive on all other substrates. TPE-1A adhesion values overmolded onto PP, PC and ABS over a wide range of melt temperatures.

These include PE, PP, ABS, SAN, PC/ABS, PC, PA6, 66 and 12, cyclic olefins (COP), high performance polymers, and elastomers such as EVA, SEBS, TPU and PEBA. APPLICATION PORTFOLIO DESCRIPTION General use Opaque and transparent colors in PP, PE, COC, ABS, POM, PC, TPU, PEEK, and more Needle hubs and cannulae Opaque and translucent colors evaluated to ISO 6009 Ophthalmic caps and closures 13 standard colors in PE matched to American Academy of Ophthalmology; biologically evaluated to USP standard White pharmaceutical packaging White colorants for PE, HDPE, PP covering solid dose to nasal packaging needs Amber pharmaceutical packaging Pre-tested amber colorants LSR silicones For LSR silicones and transparent color PET/PP (e.g. amber) FUNCTIONALITY ADDITIVE PERFORMANCE UV protection in transparent packaging Blocks UV in 290–450nm for PP, PE, PETG, COP Processing aid/friction reduction Optimizes processing for PE, PP, ABS, POM—non-migrating Nucleation for reduced material consumption/cycle time Improves thermal and mechanical properties of PE and PP and allows wall thinning to support sustainability Clarifying Improves clarity of transparent PP applications with reduced migration and improved thermal stability—sorbitol-free Laser marking/welding Activates the polymer to absorb Nd-YAG laser for fast reliable marking/assembly Gamma/e-beam sterilization Preserves the properties of PP and COP, reduces yellowing and compensates for discoloration Anti-static Reduces static buildup in applications such as films in API handling and inhaler spacers/nebulizers Antioxidant Provides thermal protection during converting/ downstream sterilization Anti-counterfeit/brand protection Covert and non-covert systems SUPPORTING SUSTAINABILITY TARGETS As the need to integrate sustainability in the design of healthcare products is growing, manufacturers of medical devices, diagnostic products and pharmaceutical packaging are looking for materials with a more environmentally friendly profile. The cycle time in injection molding can be reduced (10–15% in PP) to support higher output and less energy consumption.

Available in four overmolding grades compatible with polypropylene (PP), and one grade that is suited for overmolding onto ABS, all grades are formulated for durability, delivering property retention and UV resistance comparable to traditional TPEs.
