The company adds value to global customers and improves sustainability through formulating materials, such as:

The formulation meets stringent odor (VDA 270) and fogging (VDA 278) standards.

With its unique formulation, AAnchor offers improved recyclability, reduced regulatory risk, and enhanced bottle quality, making it the ideal solution for brands looking to incorporate higher levels of recycled material in their packaging.  

Together they developed a specially formulated pre-colored talc-filled Maxxam™ PP material incorporating OnCap™ CTR Process Optimization Additive.

They are formulated without hazardous raw materials and are highly compatible with fiber-grade polyester and polyamide, including recycled content.

The Onflex™ S TPE used by Jäger, for example, was formulated with a higher flow rate than alternative materials.

The MPS incorporates Avient’s custom-formulated GlasArmor ballistic panels that meet Level 3 protection under Underwriters Laboratories (UL) 752 standards for ballistic resistance.

The antimony vapors react with the oxygen and form a fine, white dust that is collected in a special filtration system Antimony trioxide is often used in plastic formulations in conjunction with a halogen-based chemical to reduce a product’s flammability. USES AND APPLICATIONS Antimony trioxide is predominantly used in plastics where resistance to ignition and flammability are required. It is a chemical that has been highly scrutinized by a number of regulatory bodies globally and found to be safe when used in its intended applications.
