Modification of virgin and recycled polymers
Instead of buying ready-to-use compounds, one may add directly modifiers and additives during filament extrusion.
Arkema Evatane®, Lotryl®, Lotader® and Orevac® polar and reactive polyolefin copolymers and terpolymers are used for the mechanical modification of PP, PET and PA - virgin or recycled - by pre-blending or direct addition during extrusion. They impart flexibility, elasticity and toughness.
Good elastic return of polyester matrixes may also be obtained by adding Sipol Sipolprene®.
Lotader® or Orevac® reactive polyolefins also guarantee the compatibilization of different polymers, additives, fillers, metals or impurities in the polymer matrixes, either virgin or recycled.
Ambra also designed its own range of low-cost Impact™ and Upgrade™ low-cost impact modifiers and compatibilizers to improve properties of recycled polyolefins, polyesters, natural fibers and engineering polymers.
Efficient additivation during fibers extrusion is obtained with Mesgo masterbatches.
High rate of conductivity may be obtained by Mesgo carbon black compounds Altair® PE, Avior® PP, Izar® PS and ABS, and Mizar® PA.
Mesgo SwingAdd® additive masterbatches include processing aids, slipping agents, UV and oxidant protection, temporary antistatics, etc. SwingAdd® are available as single-function additives or as a combined proprieties or colors (combi-batches).
Jazzwhite® and Tangoblack® white and black masterbatches are produced in large volumes at Mesgo Grigno plant, and they show very high concentration and excellent dispersion of the pigments on PE. PP or PA at very accessible price. Color masterbatches are produced at Mesgo Iride Colors, with very high flexibility also for small batches.
Permanent antistatic properties are obtained by the direct addition of Arkema Pebax® with the corresponding Orevac® or Lotader® compatibilizer.
Tailor-made Ambra Upgrade MB color or combi masterbatches with specific high efficiency can be developed for the coloration or modification of Sipolprene® or other TPC-ET resins during monofilament extrusion.
