A custom, impact-modified Trilliant™ HC formulation plus technical services met key needs and accelerated commercialization for a drug delivery device Avient's TPEs and engineered materials for auto-injector pens offer excellent chemical and impact resistance, good self-lubrication functions, durability to extend product life, and compliance with biocompatibility and food-contact safety regulations. 

ABSTRACT Overmolding thermoplastic elastomers (TPEs) on rigid substrates for consumer applications has been driven by the escalating market trends in enhanced ergonomic feel and touch, grip ability, aesthetics, cushioning against impact, vibration isolation and insulation. This hard/soft combination design has been driven by an escalating market trend pushing toward enhanced ergonomic feel and touch, gripping feel, aesthetics, cushioning against impact, vibration isolation or dampening and insulation. Adhesion 3 The adhesion between the TPE and rigid thermoplastics substrates was measured by a “90 degree peel test” which is a modified ASTM D903 method.

Avient GLS thermoplastic elastomer (TPE) material specialists identified a current TPE within the OnFlex™ S HF, non-halogenated, flame retardant portfolio that could be slightly modified to meet the application’s requirements. THE IMPACT By replacing traditional sealing materials with non- halogenated OnFlex S HF TPE, Schneider-Electric NB (Strömfors) was able to offer its customers several significant benefits: • For flexibility in processing, OnFlex S HF TPEs can be supplied in either natural or pre-colored grades.
