AUTOFLEX® AutoForm™ PMG

Product Data Sheet

IMD techniques are used for cost effective manufacture of fascias, panels and casings in a variety of markets. MacDermid Autotype Limited films now offer advances in the durability of the film substrate, both in terms of chemical resistance and in terms of abrasion resistance.

PRODUCT DESCRIPTION The product is a formable hard coated polymethyl methacrylate (PMMA) designed to allow shallow formability whilst retaining its abrasion resistant properties. The surface abrasion resistance of the product is superior compared with conventional hardcoated polycarbonates and the bulk hardness of the PMMA film enhances pencil hardness. PMMA film has high transparency and minimal yellowness and is particularly suitable for lenses and white goods applications. AutoForm PMG has a gloss finish on the hardcoated surface and is laminated on both sides. Product range: AutoForm PMG Gloss PMG180 2L Gloss finish 180 micron 180µ (tolerance +/- 10.5%) Key 2L – 2 sides laminate APPLICATIONS The film is designed for in-mould decoration. The part is printed on the reverse, formed and trimmed to the shape required, and finally injection moulded on the reverse to give increased rigidity. The technique has applications in:

• Telecommunications - Mobile phone/Pager lenses & body parts

• White goods - Home appliance fascias

• Brown Goods - Electronics fascias

• Automotive - Heater controls PERFORMANCE BENEFITS

• High clarity, water white

• Enhanced chemical resistance

• Scuff, scratch and gouge resistant

• Shallow formable by thermoforming, pressure or in-mould forming

• Enhanced resistance to yellowing in sunlight

PROCESS OUTLINE During the decoration steps, prior to forming, handle the film with care. Printing/Decoration: Excellent second surface decoration can be achieved with good resistance to backmoulding. Inks specifically formulated for use with PMMA films and resin are especially recommended, such as Pröll’s Noricryl or Marabu’s MACR ink range. PMMA films absorb moisture from the air more readily than polycarbonate films. It may be necessary to pre-dry the films before processing. The IMD process requires thorough drying and in many cases baking of inks for best results. The optimum ink drying temperature is between 70°C and 75°C any higher introduces the risk or warping the film.1 The hardcoating will slightly retard drying of solvent inks. Ink manufacturers recommendations must be followed. The product is not recommended for use with the Aquatex FPH range of texturing lacquers. To be able to achieve high quality lenses/display printing it is essential that processing is undertaken in a clean environment.

Forming: Forming is preferably achieved during the injection moulding process. Do not attempt deep forming with the product. Limited draw thermoforming or pressure forming by the Niebling process may be carried out after decoration. Excessive draw of the coating may cause micro-cracking which may not be visible except on microscopic examination. Thorough testing is advised on any new tooling. Cutting: To achieve the best results significant attention must be applied to the cutting of the parts.

The following advice for cutting of PMMA based films is offered by Degussa Rohm: It is recommended that the film is die-cut using only column guided matched metal tools. Steel rule tools lead to wider tolerances and are therefore less suitable. Column guided matched metal tools reach a precision of +/- 0.02mm. Preferences should be given to hydraulic presses rather than eccentric presses. The cutting gap should be between 0.01mm and 0.03 mm to achieve smooth film edges. It is recommended that the die cutter is heated to temperatures of between 60°C and 90°C before cutting. Results can be further improved by heating the film at between 60°C and 70°C. 2 The laminate on the hardcoat side (hazy) should be left on the product at the cutting stage as this will improve the cleanness of the cut. It is expected that the laminate on the print side (clear) will have been removed to undertake the decoration, however to protect against scratches and to improve die-cutting a PE laminate could then be applied to the print side after printing. For optimum results it is recommended to die-cut from the print side (non hardcoated side). Suppliers of high-precision, full section die cutters are: Offenbacher Stanzwerkzeugfabrik, Thomas Kuhne, Ludwigstrasse 30, 63067 Offenbach, Germany, [email protected], phone: +49 (0)69 829 757 0, fax +49 (0)69 829 757 25, or Carl Schlösser Gmbh & Co.

Injection Moulding: The printed, formed and trimmed part is then inserted into a suitably designed injection mould tool cavity and resin injected onto the printed side of the film. The product is particularly suitable for components moulded using PMMA resins. The following recommendations represent an overview of the considerations required for back injection moulding, for further details please contact the MacDermid Autotype Limited IMD Support Team.

• The resin must achieve a smooth laminar flow into the injection mould to reduce the

stress on the film and possible ink wash. This can be achieved by using wide fan gates located away from the edge of the film.

• To achieve good optical clarity the moulding should be undertaken in a clean environment.

• To retain a high gloss film finish the mould tool must be polished to a mirror finish.

• The injection mould tool face in contact with the film should be maintained at a temperature well below the softening point of the film to avoid distortion of pre-forms and to cool the film during moulding to avoid ink melt damage. A typical tool temperature would be between 40-50°C

HAZARDS & WARNINGS ENSURE ALL USERS READ THIS INFORMATION This product is solely intended for use as an industrial film substrate, which is screen-printable on the non-coated side with the option to vacuum/thermoform or high pressure form the film. The formed part can then be back moulded using a suitable injection moulding resin. MacDermid Autotype Limited accepts no liability for use in any other way. The main hazard associated with the film is the vapour produced when the film is exposed to heat prior to forming. Ensure that local exhaust extraction is in place to remove the vapour produced. See first aid instructions. Ensure that light cotton gloves are worn throughout processing of the film to prevent fingermarking. There is a minor possibility of irritation and/or sensitisation from the coating. Hardcoated PMMA is brittle at room temperature and may fracture to give sharp edges. Handle with care. Use lightweight Kevlar gloves if required. Do not touch the film while hot. Allow to cool before handling. FIRE PRECAUTIONS Extinguisher Media: Use water, foam, PCF, CO2 Exposure Hazards: Toxic fumes CO, CO2, NOx evolved during combustion. SPILLAGE N/A FIRST AID Inhalation of fumes during processing: Remove to fresh air. Give artificial respiration if necessary. Seek medical attention. Ingestion: N/A Eyes: N/A Skin: Wash immediately with soap and water. SHELF LIFE & STORAGE This product should not deteriorate if stored in cool, dry conditions away from light and sources of UV, in the original sealed packaging. Use recommended within two years.
