ODOUR REDUCTION | TECHNOLOGY
chemically altering the surrounding material. AqFresh is produced in a new modular manufactur- ing facility in Menadiona, Spain, which has a capacity of 500 tonnes/yr. CAI Additives offers odour-reducing additives including LDV 8010 for ABS and PC/ABS. The company said: “Already proven in automotive interior applications, especially EVs, it effectively removes VOCs without impacting mechanical or visual performance. It requires no capital invest- ment and supports typical loadings between 0.5% and 2.0%.” Another CAI product LDV-1035T has been developed for deodorisation in PP, TPO, and talc-filled compounds, including recycled grades. The company said it is ideal for odour control use in automotive trim, under-hood applications, and recycled resins. It said that both products are: free-flowing granules, easy to dose and handle; non-toxic, odorless, and stable in processing; and designed for permanent effect, not temporary masking. In March this year, Evonik launched Tego Sorb
PY 88 TQ, a zinc ricinoleate-based odour absorber designed for use in polymer compounding and
masterbatch production. It functions by binding malodorous compounds such as hydrogen sulphide, mercaptans, thioethers, isovaleric acid, amines, and ammonia, effectively neutralising them without imparting any additional fragrance. This additive is particularly suitable for polyole- fins (LDPE, PP) and recycled PA. It also aids in reducing odours during the dispersion of pigments such as ultramarines, yellows, and oxidised carbon blacks. For applications involving all-acrylic, vinyl-acrylic and styrene-acrylic copolymers – with malodorous butyl acrylates – an aqueous formula- tion of Tego Sorb PY 88 TQ is available. In processing, Tego Sorb PY 88 TQ can be dry-blended before compounding or directly fed into the extrusion line. However, because of its low melting point of 88° C, care should be taken to prevent feeder overheating. Direct use of the 100% active form in single-screw film lines is not recom- mended, as it may lead to inhomogeneous distribution and processing issues. For such cases, Evonik offers PE or PP-based masterbatches containing Tego Sorb PY 88. The recommended dosage ranges of the additive fall between 0.5% to 2.0%. The company
