Mevopur products cover the wide range of polymers and thermoplastic elastomers (TPEs) used in the medical and pharmaceutical sectors. 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. Examples of custom formulations that help achieve a more sustainable product profile are a nucleating agent combined with color in a ready-to-use formulation or a desired color offered in a bio-polymer based ready-to-use product.

Exploring the performance of various TPE types Home // Understanding the Chemical Resistance of TPEs The adaptability of TPEs makes them useful across industries and applications, but it is important to consider all factors in order to properly determine if a TPE is the best fit and select the right formulation for your application.  

Explore the design options & challenges of TPEs with sustainable content Home // Balancing Beauty and Sustainability with TPEs TPEs can incorporate sustainable content in two ways: using either recycled or bio-based content in the formulations.

TPE Technical Bulletin Selecting a TPE material to be used in your application may involve many factors: The part mass would be 24.6 cm^3 x Specific Gravity of TPE material.

The new formulations are Avient’s first PCR-containing TPE technology developed primarily for overmolding polycarbonate (PC), acrylic butadiene styrene (ABS), and PC/ABS blends in applications from consumer electronics, cosmetics packaging, and personal care items to power tools and toys. They offer a performance property profile, including adhesion, surface quality, and soft touch feel, comparable to prime TPEs without recycled content. Our new reSound REC family of PCR-based TPEs addresses these challenges and reflects Avient’s firm commitment to sustainability and accelerating the transition towards circularity.”

During the extrusion process, Cesa™ Process Additives coat the inner surface of the die, reducing the friction between the melt and the metal and allowing polymers to extrude more easily. Allows polymers to extrude more easily

The automated pultrusion process fabricates continuous glass or carbon fiber-reinforced, constant cross-section profiles with consistent, uniform properties.  For the brace, Avient's engineering team developed and analyzed three options: a unidirectional, hybrid carbon and glass fiber profile; a unidirectional carbon fiber profile; and finally, a profile made with both a unidirectional carbon fiber and a transverse engineered fabric, which had the advantage of minimizing any potential cracks from propagating. The third profile was also 41% lighter than aluminum, with a 50% increase in flexural stiffness, and maintained torsional rigidity slightly better than that of aluminum.
