Edgetek™ ET8900 CR Series Chemically Resistant Thermoplastics Deliver Advanced Protection Today’s increased disinfecting and cleaning protocols can lead to deterioration and reduce the useful product life for polymeric materials that lack proper chemical resistance properties. Developed to meet these challenges, Edgetek ET8900 CR thermoplastics show improved chemical resistance to common consumer disinfectants compared to PC/ABS, PC/PET and PC/PBT.

Edgetek™ PKE High Impact Formulations The Edgetek™ PKE High Impact (HI) series consists of specialty engineered, impact modified polyketone (PK) thermoplastics. Formulated to deliver high performance in chemical, fuel contact, and high moisture environments, these thermoplastics are useful in applications found in the industrial, electrical/electronics, transportation and powersports industries.

CASE STUDY: COMPLĒT™ MT LONG FIBER REINFORCED THERMOPLASTICS Challe nge Accepted. And, because they are formed by injection molding, long fiber reinforced thermoplastics can be easily customized to specific design requirements.

Cesa™ Stat Antistatic Additives Cesa™ Stat Antistatic Additives control the buildup of static charges in thermoplastic parts, enabling them to dissipate by absorbing and ionizing moisture from the air, which forms a conductive path for surface static charges. PRODUCT BULLETIN KEY CHARACTERISTICS • Eliminates electric charges to maintain good product appearance • Creates safer, static-dissipated parts for electronics, packaging, automotive, and military applications • Improves product appeal by reducing static charge-related dust accumulation • Reduces the risk of a potential fire hazard in product environments • Reduces cycle times, maximizes throughput, and lowers operating costs • Can be combined with other additives or colorants into a single masterbatch • Compatible with a variety of processes including blow molding, injection molding, extrusion, and film processing • FDA-approved and bio-based formulations available MARKETS AND APPLICATIONS Cesa Stat Antistatic Additives are suitable for any thermoplastic application that could benefit from reduced static buildup, including: • Automotive under-the-hood components • Automotive dashboards • Electrical connectors & components • Electronic components • Military components • Consumer packaging ARE YOU IN A BATTLE WITH STATIC?
