5 What are Special Additives? Special additives include special anhydrides and special esters. The company is one of the world major manufacturers of these products. Special Anhydrides Special anhydrides are maleic derivatives manufactured starting from maleic anhydride and conjugated double bonds compounds i.e. butadiene or isoprene. Some anhydrides grades can be further transformed by hydrogenation in order to impart them additional performance properties for example higher UV stability. Thanks to its backwards integration in Maleic Anhydride, Polynt S.p.A. is a world major manufacturer of Special Anhydrides being the only European producer of such products. Our anhydrides are used in several industrial applications. As hardeners for epoxy resins in the electronic and electrical markets for the manufacturing of: LED and PCB (printed circuits boards); insulation of motors and generators, insulators, bushings and switchgears; electronic transformers and semi-conductors As hardeners for epoxy resins in industrial sectors: high/medium pressure pipes for oil & gas and reverse osmosis; wind turbine blades and wind mill components, pultruded parts for electrical and composite applications As raw materials for manufacturing resins for paint and coatings, plasticizers and as intermediate for miscellaneous applications. 5

Special Esters Special Esters represent a large family of products like acetates, glycerol derivatives, low-molecular weight phthalates, citrates, maleates, fumarates, succinates and other organic

6 Special Esters Special Esters represent a large family of products like acetates, glycerol derivatives, low-molecular weight phthalates, citrates, maleates, fumarates, succinates and other organic esters used in special applications. They find a wide range of applications such as: flavours and fragrances (solvents, fixatives, additives) cosmetics (emollients, solvents and plasticizers) food (additives, ingredients) pharmaceutical (excipients) polymers and plastics (plasticizers) paints and coatings (solvents and coalescent agents) adhesives (solvents, plasticizers) inks (plasticizers, solvents) peroxides (extenders and solvents) foundries (binder agents for molds and hardeners) tobacco (plasticizers for cigarette filters) leather (finishing agents) lubricants (metalworking additives) textile (additives) 6

7 Special Anhydrides Methyltetrahydrophtalic anhydride (MTHPA) Methyltetrahydrophthalic anhydride is widely used in various transformation technologies such as casting, impregnation and lamination. The product remains liquid also at low temperatures allowing an easy handling and mixing with the epoxy resins and providing long 'pot life' mixtures. Thanks to its excellent insulation properties it finds applications for the manufacturing of several different electrical components and articles, such as capacitors, insulators, resistors, transformers, ignition coils and various similar components. In the field of reinforced plastics it is used for the production of composites throughout filament winding and pultrusion technologies (pipes for medium-high pressure, bars, poles and components for wind turbines). It is available in different grades, the most important being: MTHPA NT: anhydride for multipurpose applications, particularly useful in the field of electrical insulation MTHPA TT: low viscosity MTHPA PI: shows resistance to UV and atmospheric agents, making it similar to hydrogenated anhydrides MTHPA 604: anhydride with excellent performance/price ratio; it is recommended in the electrical and composites fields MTHPA NG: reference MTHPA grade, suitable for a wide range of applications, in particular for the electrical insulation and composites 7

Methylendomethylentetrahydrophthalic anhydride (METH) Methylendomethylentetrahydrophthalic anhydride or Methylnadic Anhydride (METH) is a high performance curing agent for epoxy resins.

8 Methylendomethylentetrahydrophthalic anhydride (METH) Methylendomethylentetrahydrophthalic anhydride or Methylnadic Anhydride (METH) is a high performance curing agent for epoxy resins. It is also known as Methyl-Himic Anhydride, a low viscosity substance thus can be easily mixed with different liquid resins providing long pot life mixtures. Compared to other anhydride hardeners, epoxy materials obtained using the methylendomethylentetrahydrophthalic anhydride show higher thermal and better electrical properties. Thanks to its low exothermic behaviour it s recommended for casting and large impregnation. It is available in different grades, as follows: METH E: Reference product recommended for applications in which higher thermal and electrical performances are required METH ES: is purer than METH E. When it is used with basic accelerators it forms less carbon dioxide and gives a better retention of colour on the finished product. 8

9 Special Anhydrides - Special Hydrogenated/Cycloaliphatic Anhydrides Hexahydrophthalic anhydride (HHPA) The above is primarily used as hardener for epoxy resins and as an intermediate for the production of alkyd resins. Due to its high resistance to yellowing, it is the most suitable solution, compared to other cycloaliphatic anhydrides, for applications that require resistance to outdoor conditions (weathering resistance). The low viscosity of the melting point and its high mix ability with the epoxy resins makes this anhydride particularly suitable for reinforced applications. Methylhexahydrophthalic anhydride (MHHPA) Thanks to its cycloaliphatic structure, it imparts an excellent resistance to UV radiations and weathering. As a hardener for epoxy resins, it contributes a very white-water slight coloration, excellent mechanical and electric properties to the finished product. For this reason it s particularly suitable for electrical applications or special electronic purposes such as high-performance LEDs. It is available in different grades; the most important are: MHHPA: It s the reference product suitable for general purpose applications suggested when excellent mechanical and chemical properties are requested in association with good colour retention. It is recommended for the production of transformers suitable for external use and general purpose led MHHPA WW: It is a very pure material water-white in colour, with outstanding colour retention even when it s heated for a long period at high temperature. Suitable for high performance led (O.E.M.) MHHPA S-37: its use is recommended when requiring excellent mechanical properties, electrical insulation and chemical resistance in combination with good colour retention. It is formulated to impart a good colour retention in general LED lighting applications. 9

10 Anhydride 70/30 It's particularly used as a hardener for epoxy resins and as a component for special coatings. Its use is recommended when excellent mechanical, electrical and chemical properties, associated with a good colour retention, are required. It is suitable for the production of articles intended for outdoor applications. Succinic anhydride It is mainly used for the manufacture of alkyd resins and copolymers, as a crosslinking agent in acrylic films, special elastomers, in the manufacture of chemical products, pharmaceuticals, chemical esters for several applications, as intermediate for the production of modifiers of starches and as a chemical intermediate in the manufacture of dyestuffs. 10

11 Special Anhydrides - Pre-accelerated and modified special anhydrides and others MTHPA 700 PL / N Modified and pre-accelerated methyltetrahyrophthalic anhydride: it is particularly suitable, through the filament winding technology, for the production of high pressure pipes intended for reverse osmosis desalination plants. MTHPA / NT K1 Pre-accelerated methyltetrahydrophthalic anhydride: it is suitable for the production of electrical components. MTHPA 700 K3 Modified and pre-accelerated methyltetrahydrophthalic anhydride: it finds applications in the production of medium-highpressure pipes appliances. Other anhydrides are available on request and / or for special applications Thanks to its experience and competence in Research & Development of special anhydrides, Polynt is able to offer its customers tailor-made solutions to better satisfy the various needs of process and performance. Do not hesitate to contact our Customer Service or Technical Assistance. Anhydrides can easily hydrolyze to the corresponding diacids that are melting solids insoluble in anhydrides. It is therefore important to preserve anhydrides and the system where they are contained from moisture. 11
