- Huge freedom of design, low weight and option of integrating a variety of functions
- Specialty molding compound for injection molding and extrusion
Darmstadt. - Plastics such as polymethyl methacrylate (PMMA) have long been established in a variety of vehicle applications, where they are used, for example, as durable taillight covers and non-transparent add-on body parts. In others, they are conquering growing shares of the market. These include applications in vehicle interiors, such as decorative trim, ambient lighting and door entry strips. Glazing with plastics is one of the fields that offer the highest growth potential.
Weight savings, freedom of design and the integration of many different functions: these are the major benefits of plastic glazing as compared with conventional glass.
PLEXIGLAS® Resist AG 100 is the world’s first PMMA specialty molding compound for this application. It offers the high resistance to UV light and weathering for which PLEXIGLAS® is known, is impact-modified and has up to 30 times the breaking strength of mineral glass. Our developers have also succeeded in significantly reducing the reversible haze that occurs in conventional impact-modified products at very high and low temperatures.
Owing to its balanced property profile, the new specialty molding compound meets all the relevant requirements for the field of automotive glazing.
It has also undergone and passed all tests in line with ECE R43. The test report of the Materials Testing Agency of North Rhine-Westphalia is available for systems based on PLEXIGLAS® Resist AG 100 for rear side windows, roof and rear windows.
The new specialty molding compound can be processed by means of all thermoplastic processes such as injection molding or injection compression molding of parts, or by extrusion with subsequent sheet thermoforming.
PLEXIGLAS® Resist AG 100 also comes up trumps as regards subsequent hard coating. The material provides already an inherent resistance to UV light and weathering. Thus the one-step coating is applied to increase the already good abrasion resistance of PLEXIGLAS still further. One-step coatings that are suitable for PLEXIGLAS® have been successfully tested and also meet the requirements of ECE R 43. Other thermoplastics that are less weather-resistant have to be protected by means of a two-step coating process, which entails higher costs. The subsequently applied UV-protection also impairs the mechanical performance of the coating.
The new PLEXIGLAS® Resist AG 100 therefore offers almost unlimited freedom to designers when it comes to developing unusual designs with curved lines and pronounced edges. This also applies to components made from this material, which unite several functions at the same time, such as non-movable quarter window, black pillar cover and taillight all in one.
Another convincing feature for the automobile industry is the good life cycle assessment of PLEXIGLAS®, which was determined and confirmed over the product’s entire life cycle in accordance with DIN ISO 14040ff. And at the end of a car’s service life, PLEXIGLAS® can be completely recycled and used again for other transparent applications.
Besides applications in automotive glazing, PLEXIGLAS® Resist AG 100 can also be used wherever there is a need for high impact strength combined with very low haze at high temperatures.
Evonik is a worldwide manufacturer of PMMA products sold under the PLEXIGLAS® trademark on the European, Asian, African and Australian continents and under the ACRYLITE® trademark in the Americas.
