Coated Polycarbonate & Acrylic (PMMA) Sheet

As the exclusive UK and Ireland stockholder and distributor of KRD Polycarbonate sheet, Optical Coating Technologies stocks a wide range of thicknesses. The full range of sheet thickness is from 1mm through to 20mm.

Optical Coating Technologies can supply the sheets coated with an optically clear abrasion resistant coating, an anti-static coating and/or a non-glare finish (with differing levels of non-glare being available). All the coatings are abrasion resistant and chemical resistant.

The sheets can be supplied as full size 3m x 2m pieces, cut down to size, CNC profiled or fabricated to your final specification using our in-house equipment. Ideal for use in signage, instrument panel covers / doors and windows.

We can also supply Lexan Polycarbonate and Makroclear Polycarbonate as well as PMMA (Acrylic) sheets.

 

The KRD Polycarbonate sheet is available in a wide range of colours. Suitable for internal architectural use, these plastic sheets are perfect for internal windows and partitions within offices, food factories and public buildings. So now designers and architects have the ability to add new dimensions and functionality to their creations.

For external use UV stable Polycarbonate is offered. Guaranteed for 10 years against breaking or yellowing caused by UV light, these coated sheets are ideal for external signage and ballistic glass applications.

The building industry has a demand for continuously lighter and more robust materials. Polycarbonate sheet from our principal KRD fulfills these requirements while offering superior solutions for aesthetics.
In urban development, KRD Polycarbonate is primarily used for urban modernisation: bus stop shelters, panels for large banners, bicycle shelters, street lamps or train platform roofs.


The Olympic Stadium Spiros Louis in Athens is the largest public building that had used KRD plastic panels at that time. The entire roof of the Olympic Stadium and also the roof of the swimming pool and various protection walls were built in abrasion resistant coated Polycarbonate sheet.


KRD tinted panels have a wide variety of uses in interior design, such as for example as artistic elements in stage, trade fair or facade design. 

 

Since the early 1980s, KRD has supplied the German police with glazing for its patrol cars. Two window qualities are offered, namely the mono- and the laminated window pane. Unlike silicate glass, our glazing is highly impact resistant and largely break-proof. Specialist vehicles such as water cannons and fire vehicles have also been equipped.


In October 2010, the KRD compound pane SCS-V44 received the general type approval (certificate issue by the German Office for Motor Vehicles – KBA). It is the first laminated plastic pane in the world to receive the KBA approval. KRD Polycarbonate has many applications in the area of personal and business security, such as in official and government vehicles as well as private limousines.
