ACRYLIC WINDOWS

AS-CAST ACRYLIC WINDOWS

Thermoplastic polymers such as acrylic are used in numerous aircraft and rotorcraft applications, because it readily accommodates the manufacture of clear lightweight complex-shaped transparencies. As-cast acrylic is typically used for helicopters and non-pressurized aircraft transparencies.

STRETCHED ACRYLIC WINDOWS

Stretched acrylic windows are obtained by stretching as-cast acrylic sheets; a process which re-orientates the long polymer chains. Stretching drastically increases the material properties. Unlike as-cast acrylic, stretched acrylic also offers an improved craze resistance, increased stress tolerance, crack propagation and solvent resistance. As such, it is highly suitable for acrylic windshields, outer cabin window panes and other transparencies, even for aircraft fitted with pressurised cabin spaces.

LIGHT WEIGHT AND VERY RESILIENT

ACRYLIC WINDOWS - BELL UH-1Y VENOMDue to the very high speeds and high level of hazards involved if flying, the acrylic windows we supply to iconic aircraft and rotorcraft corporations are of the very highest quality and must be flawless in every sense of the word. Indeed no acrylic windows are put into production prior to rigorous testing because no other industry demands a higher standard of product quality and durability.

OTHER APPLICATIONS

Aside of the aerospace and defence industries, acrylic windows can be fitted pretty much into any vehicle, equipment or device requiring a strong transparency. Indeed acrylic  is a highly versatile polymer affording endless applications.

Although CLI has benchmarked its experience on these most challenging industries, we have the capability and resources to develop acrylic windows for any vehicle or application where safety, durability, light weight and reduced production costs are an essential requirement.

FLEXIBILITY TO CREATE YOUR EXCLUSIVE PRODUCT

So whatever your acrylic windows requirement may be, we can create your product from acrylic, with the benefit of a hard coating finish to afford it durability and a trouble free life-cycle. These days there are so many benefits to using acrylic as a substitute to glass and at considerable less production costs too.

POLYCARBONATE WINDOWS

EXCEPTIONAL PROPERTIES

Polycarbonate windows possess the superb property of exceptional strength, providing high impact resistance. In addition to its light-weight, these properties make it the ideal material for the design of windshields subjected to high velocity bird strikes. Furthermore, polycarbonate windows provide excellent high-temperature tolerance. Susceptible to stress-solvent crazing, it is highly recommended polycarbonate items only be used with an applied protective hard coating.

POLYCARBONATE WINDOWS - LITTLE BIRD

PROTECTIVE COATING

Protective Coatings for polycarbonate windows are used to prevent deterioration from extreme weather or environmental deterioration ― including ultraviolet rays ― as well as solvents and chemicals. Equally, hard coats, also protect polycarbonate windows against harsh conditions such as abrasion caused by sand and dirt or sea salt. Coatings can be applied by means of flow, dip or spray and are generally thermally cured.

OTHER APPLICATIONS

Polycarbonate windows can of course be applied to any vehicle or product device calling for hazardous impact protection, such as those found in performance vehicles, warehouse fork lift trucks, agriculture, roadwork, or other heavy construction machinery.

Not only is polycarbonate light-weight, but its high impact resilience properties means it is a a far superior alternative for safety glass, which can often shatter into thousands in pieces when subjected to a hard blow.

POLYCARBONATE vs. GLASS

Due to the limited strength of glass, further protection of the driver cabin is frequently required, almost imperative, and thus many of these machines have cabins are completely encapsulated by protective steel cages, which can of course reduce visibility substantially thus increasing the probability of an accident.

However, polycarbonate windows are a perfect substitute for glass, thus in most cases the steel protective cage is no longer required. For those instances where a large pane is required, a far less obtrusive cage could be implemented.

FLEXIBILITY TO CREATE YOUR EXCLUSIVE PRODUCT

So whatever your transparency requirement may be, we can create your perfect polycarbonate window for you. Choosing a polycarbonate window will afford you the benefit of a light-weight, highly durable product, with the assurance of maximum safety.

THERMOFORMING

PRODUCTS CATEGORIES

We specialize in advanced thermos-polymer formations in stretched acrylic, cast acrylic and polycarbonate, always with minimal optical distortion and aberration. CLI can also offer forms in fiberglass laminate for applications such as window edgings.

EXPERIENCEACRYLIC AND POLYCARBONATE PRODUCTS - THERMOFORMING

Our enterprise possesses comprehensive experience with acrylic and polycarbonate products, employing the latest and most advanced techniques within the industry, to achieve precise contour control, creating the very highest quality products for strength and durability.

TECHNICAL EXPERTISE

Within the acrylic and polycarbonate products transparency industry, our specialty is working with bi-axially stretched acrylics, (MIL-PRF-25690) ― a stronger, crack propagation resistant acrylic; cast acrylics (MIL-PRF-8184, and MIL-PRF-5425), and polycarbonate for products requiring very high impact resitance.

CLI also employs various industry standard techniques such as drape forming, vacuum forming, wet forming, and blow forming, to achieve precise control of window contours, yet always maintaining defect and distortion free optics.

FLEXIBILITY TO YOUR EXACT REQUIREMENTS

We are also capable to form acrylic and polycarbonate products on customer supplied tools, or able to assist you in the development of specific products and help you build new tools for complex forming applications.

CERTIFICATION

CLI holds a BSI AS9100 certificate in quality assurance and has received various accolades for its exceptional acrylic and polycarbonate products and services. We are proud to benchmark our service on meeting, and often exceeding, customer requirements for both process controls and product inspection.

HARD COATS

INTRODUCTION

Hard coats are applied to formed acrylic and polycarbonate products in our class 100 clean room providing protection from surface damage and environmental degradation. CLI has invested heavily in the technology of hard coats. Our financial commitment of and assiduous dedication to research and development allows us to provide the very best product solutions for even the most difficult application.

ACRYLIC AND POLYCARBONATE PRODUCTS - HARD COATSAs a Post-Coater (applying our coatings after they have been formed), we offer the industries’ highest level of performance coatings.

      1. Abrasion Resistance
      2. Chemical Resistance
      3. Clarity
      4. Anti-Fog Performance

FIVE STEP PREPARATION

CLI has developed a meticulous five-step cleaning process to prepare all acrylic and polycarbonate products for coating in our class 100 clean room. Fluids are tested for every session and environmental conditions are always well controlled to ensure we offer consistent, superior results in the field. CLI has never had an acrylic or polycarbonate product returned due to poor performance of its hard coat.

POLYCARBONATE

Our exclusive Polycarbonate Hard-Coat offers your product the highest level of performance available today. Our hard-coat is able to repel water better than any temporary window treatment, and is so durable it will withstand the use of wipers when necessary.

SILICONE BASED TREATMENTS

CLI can meet customer requirements for silicone based hard coats on polycarbonate and acrylic transparencies. This is a well-developed process which has been perfected to ensure coatings provide not only lasting protection, but also without any negative effects on the optical characteristics of the transparency.

COUPON TESTING

Coupon testing is performed after every batch run to ensure best adhesion, chemical and environmental resistance, and of course optical clarity.

BONDING AND ASSEMBLY

Thermoformed acrylic and polycarbonate products are custom routed to final size and the faying surfaces are carefully prepared for bonding. Formed edgings are then hand-crafted to precisely match the formed windows within the required tolerances.

BONDING OPTIONS AND MATERIAL DIVERSITY

CLI has bonding experience with fiberglass, ABS, Kydex, nylon and several other edging materials. We can build assemblies ready for final installation with attachment holes machined, or with excess material for final installation by the client in their facilities.

BELL HELICOPTER CERTIFICATIONS
