Frequently Asked Questions
Can PLEXIGLAS® be recycled?
As an innovative company with international operations, we consider the protection of our environment to be an essential factor when it comes to safeguarding the future of our planet. Our corporate policy therefore places equal emphasis on the sparing use of energy resources and on the development and manufacture of products that are safe and environment-friendly when employed in the correct quantities, and can be recycled or safely disposed of at the end of their service life.
Mechanical recycling means that parts made from PLEXIGLAS® molding compound can be ground and repelletized after correct separation, and reintroduce into the processing cycle. Since the recycling process leaves the original properties of PLEXIGLAS® more or less intact, the products manufactured from recycled material are of the same high quality as the original ones.
Chemical recycling is a process in which PLEXIGLAS® is reduced to its original monomer unit of methyl methacrylate, from which new PLEXIGLAS® or methacrylate dispersions/emulsions, for example, are built.
Both chemical and mechanical recycling are ways of obtaining high-quality material again from a high-quality product. Naturally, the optical appearance may suffer from impurities introduced during reprocessing.
In thermal recycling - if correctly incinerated - PLEXIGLAS® only gives rise to water (H2O) and carbon dioxide (CO2), i.e. no pollutant emissions. From this point of view, it is even superior to fossil fuels, which contain sulfur etc.
Does PLEXIGLAS® produce toxic vapors during combustion?
PLEXIGLAS® molding compound and moldings are combustible, like all organic substances. The ignition temperature is approx. 425 °C. Acc. to DIN 4102, PLEXIGLAS® burns with a luminous, non-sooty flame and produces (non-burning) droplets. Combustion gives rise to water and carbon dioxide, as well as carbon monoxide in the event of a lack of oxygen. Beyond these, no toxic gases are produced. For further information on individual PLEXIGLAS® molding compounds, please refer to our "Product Information, Fire Behavior."
How can PLEXIGLAS® scrap be disposed of?
Owing to its properties, PLEXIGLAS® is primarily intended for the manufacture of durable, high-quality articles and less so for products meant to be consumed and disposed of within a short time. Thanks to its resistance to aging and weathering, PLEXIGLAS® remains fully functional even after many years of service, and does not need to be replaced at an early stage. Given correct fabrication, PLEXIGLAS® releases no pollutant substances to the environment. At the end of its product life and after careful separation from other materials, PLEXIGLAS® can be used for energy recovery and chemical or mechanical recycling.
PLEXIGLAS® scrap is not classed as hazardous waste. Small quantities can therefore be disposed of as household refuse.However, large quantities should be disposed of in compliance with the regulations, after consulting the responsible local authority and the disposal company, at a suitable licensed plant.
Contaminated packaging must be emptied as far as possible, and can then be passed on for recycling after professional cleaning. Non-contaminated packaging can be passed on for recycling. Packaging than cannot be professionally cleaned must be disposed of in a suitable manner.
The EEC waste identification code for PLEXIGLAS® is 070213.
Are safety data sheets available for PLEXIGLAS® products?
Yes, our customers can receive safety data sheets on request. Please use our Contact form.
Is PLEXIGLAS® environmentally compatible?
If correctly processed, PLEXIGLAS® releases no harmful substances to the environment. The basic grades consist of the elements carbon, hydrogen and oxygen. Many grades are employed in food-contact applications and the medical sector.
Do you have a quality certificate?
Quality is an outstanding characteristic of our products and services. Quality management has been introduced for many years in the various Business Units of Röhm GmbH, including Business Unit Methacrylates. Röhm GmbH has been certified to ISO 9001:2008, ISO 14001:2004 and BS OHSAS 18001:2007. In addition the quality management system of Business Line Molding Compounds has met all the stringent requirements of ISO / TS 16949:200of the automotive industry. All processes for manufacturing PLEXIGLAS® molding compounds are subject to a continuous improvement scheme and are monitored by a modern quality management system.
Do you have environmental statements for your plant sites?
Following the implementation of the EU Eco-Management and Audit Scheme (EU EMAS) into German law, we at Evonik Röhm GmbH decided to perform comprehensive environmental audits and examinations of the environmental management system, covering all production areas at all our sites. These internal audits have in each case been monitored by an independent accredited environmental verifier.
What is the fire rating of PLEXIGLAS® molding compounds?
PLEXIGLAS® molding compounds and moldings made from them are combustible, like all organic substances. According to DIN 4102, PLEXIGLAS® burns with a luminous, non-sooty flame and emits (non-burning) droplets. PLEXIGLAS® is classed B2, normally flammable, to DIN 4102 Part 1 (August 1998). For the fire rating and fire behavior according to various standards, please consult our "Product Information, Fire Behavior".
Can one eat or drink out of items made from PLEXIGLAS®?
PLEXIGLAS® standard molding compound can be used without reservation for manufacturing items entering into contact with foodstuffs. They comply with the requirements of FDA Regulation CFR 21 § 177.1010 (01.04.2001), European Directive 90/128/EEC incl. 2001/62/EC (09.08.2001) and German Recommendation XXII of BgVV (09.01.2001) (formerly BGA, German Health Agency), as well as the requirements of LMBG Lebensmittel- und Bedarfsgegenständegesetz (German law on foodstuffs and commodities) (20.07.2000).
For the classification of our impact-modified molding compounds, grades with a higher heat deflection temperature under load and specialty molding compounds, please refer to our product information sheet "PLEXIGLAS® Molding Compounds, Food-Contact Rating."
