Three new additive blends that target odor and VOC control for use in automotive, packaging or recycled applications have been unveiled by Struktol Company of America, Stowe, Ohio. These products can range from simple odor mask/lubricant blends designed to disguise odors to complex neutralizer plus absorber blends intended to deactivate specific odor-causing species and fix low molecular weight volatiles in plastic resins and compounds. All are said to be effective at ow loading levels and can be easily added into most processes including compounding, direct extrusion and injection molding.

● RP 17 is a combination lubricant and odor neutralizing mask that was originally designed to reduce process-generated and end-product odors in wood-filled plastic compounds. It has been modified for use in a variety of thermoplastic resins and compounds that require the multi-functionality of lubrications, mold release, and odor reduction. It can be used in recycled applications and interior automotive compounds.

● RP53 is a blend of odor neutralizing chemistries that is reportedly ideal for difficult, high-odor compounds containing problematic species such as mercaptans, amines and phosphites. The product can be used in a variety of thermoplastics but is primarily targeted to polyolefins in both recycled applications and interior automotive.

 

● RP 59 is a blend of odor neutralizing chemistries and VOC absorbers intended for difficult, high-odor, and high-volatile content compounds. It can be used in a variety of thermoplastics but is primarily targeted to polyolefins. It is reportedly very effective in packaging applications to not only reduce or eliminate odors in the polymer but also absorb odors coming from the packaging product.
