KEY CHARACTERISTICS • Manufactured at four ISO 13485 certified sites, providing global consistency and increased security of supply • Documented change control beyond CAS number, reducing risk of change • Non-phthalate and formulated without animal- derived substances • Available for use in a wide range of polymers including polyolefins, styrenics, polycarbonate and alloys, polyester, POM • Functionality can be combined with colorants into convenient combination concentrates or formulations REGULATORY SUPPORT • Pre-tested raw materials: - ISO 10993-1 and USP biological evaluation - European Pharmacopeia 3.1.3/3.1.5 (polyolefin) - USP (polyethylene) - ICH Q3D elemental impurities • Registered Drug Master File (Type III) • Food contact established with FDA/EU* APPLICATION BULLETIN * FDA/EU compliance information available upon request FUNCTIONALITY TARGET APPLICATIONS EBM/IBM CONTAINERS CLOSURES FILM COMBINATION DEVICES Clarifying PP Sorbitol-free—possibilities in packaging ocular solutions    Slip/torque reduction Slip for PE, PP films, processing aid, torque reduction for closures   Protection from UV in transparent packaging for PP, PE, PETG, COP UV blocking in 290–450nm with no impact on clarity    Antistatic ready-to-use solution for PE films e.g. for API handling Permanent/non-migrating; fast decay time independent of % relative humidity  Antistatic masterbatch for PE films Cost effective, long-lasting, migrating type but with biological evaluation  Gamma/e-beam sterilization protection of the polymer Preserving the properties of PP and COC/COP. Reduction in yellowing using Color Compensation Technology (CCT)   Reduced material consumption/cycle time/improved properties—nucleation Fast acting new generation nucleant for PE and PP; improved dimensional stability, thermal and mechanical properties    Laser marking replacing ink printing/labels Solvent-free, high-speed identification for Nd/YAG laser    Antiblock for PE/PP film Non-migrating additive system maintaining high gloss and printability  Antioxidants for PE, PP, TPE Thermal protection during converting/ downstream sterilization     Brand protection/ anticounterfeit Range of covert and non-covert systems    Volatiles/odor absorber for PE/PP Physical absorption of a wide range of molecules responsible for odor, VOC and potential extractables/ leachables in plastics   Healthcare use limitations apply—see below.

It’s challenging to produce interior automotive parts that are both cost effective and able to meet high consumer expectations for quality. Our TPEs combine high quality, high productivity, and low production cost to meet your needs, whether you’re an OEM or a supplier. A high productivity manufacturing process that drives low per-part cost is crucial for dealing with cost pressures.
