From Plywood To Polycarbonate Sheet

People in the plastics industry have known for over 50 years that Polycarbonate Sheets are tough. This clear plastic sheet material is commonly used to replace window glazing. The best known property for this sheet materials is that it is break resistant, or in many cases, unbreakable. This is a great benefit for areas where window glass is broken easily.

Recently some cities have passed ordinances to change out the plywood window coverings on abandoned homes, and they are installing clear polycarbonate sheets instead. This is a very attractive replacement, and is a big step in fighting the blight of abandoned homes.

Polycarbonate is produced under several trade names, including Covestro Makrolon®, SABIC Lexan®, Cyrolon®, Zelux®, Tuffak® and many more. These materials are available in sheets, plate, slab, bar and rod.

Cities moving from Plywood to Polycarbonate Sheet Protection for abandoned homes

Excerpt from AZCentral, The Arizona Republic:

Property owners and banks in Phoenix had begun outfitting windows with sheets of polycarbonate, a thin, nearly indestructible plastic that mirrors the appearance of glass.

And last month, the city became among the first in the U.S. to make polycarbonate windows a matter of municipal law.

Phoenix now requires all window and door openings visible from the street to be secured with the material if the structure has been unoccupied for more than 90 days. The 90-day provision is also new, replacing the previous deadline of 180 days. The measures were the result of an abandoned buildings task force that Gallego spearheaded.

Durham County, North Carolina also made a change:

By Taylor Knopf, tknopf@newsobserver.com

No one likes living next to abandoned buildings with boarded up doors or windows. So the city of Durham started replacing the plywood eyesores with a clear, durable plastic.

The city is working to reduce the number of abandoned houses by helping owners fix them up. But for houses that still need boarding up, the city has found that plastic not only improves the overall appearance of a neighborhood, it may reduce crime by discouraging squatters and making it easier for police to see inside vacant buildings.

“I can’t stress enough how the elimination of the boards has a tremendous positive impact on neighborhoods and communities,” said Faith Gardner, housing code administrator of the city’s department of neighborhood improvement services.

These communities have fought back against vandalism and crime, as well as enhanced the value of local homes by changing from Plywood to Clear Polycarbonate Sheets. This super tough Bullet resistant Polycarbonate Sheetglazing grade clear Polycarbonate Sheet material is the same kind of material that Police Officers use for face shields and banks are using for bullet resistant glazing.

The premier manufacturer of Polycarbonate Sheet in the USA is Covestro (formerly Bayer MaterialScience), and they produce Makrolon Polycarbonate Sheet. Polycarbonate is also available in rod and thick plate for machined parts.

Consider using Polycarbonate sheet for your next glazing material.

What is the Strongest Plastic – Polycarbonate Sheet?

Many plastics are durable and have good impact strength. Delrin® – Acetal for example is a very durable and strong material, but compared to some other materials the impact strength is lower. The Acetal – Delrin is the best machining plastic around, it is used to make long lasting and good wearing parts for machines. Another great plastic that holds up to wear and tear is UHMW. With its high molecular weight and low friction resistance is ideal to take abuse over long periods of time.

However, one of the strongest materials in the plastic family is Polycarbonate. Commonly Polycarbonate Sheet or Sheets formed into Riot Shieldsreferred to Lexan® (SABIC) or Makrolon® (Bayer) Polycarbonate Sheets. Polycarbonate is by far one of the strongest (highest impact resistant) ­­­­­plastic materials, and is warranted against breakage. With its high impact strength, it is ideal for jobs were the ability to absorb abuse is a factor and in some cases may even need to save lives. A common material for high impact is Polycarbonate Sheet and Plate, but amazingly also Polycarbonate Rod.

Polycarbonate Sheets considered ‘unbreakable’.

Polycarbonate sheet is a valuable plastic due to its impact strength, temperature resistance and wide range of uses. It is commonly confused with Acrylic or Plexiglass which has similar properties but Polycarbonate is 25 times stronger and has a wider temperature range. Acrylic is better used for display purposes and is a brittle material. Polycarbonate is so strong that you can drill or hammer a nail right through it without breaking the material. It also can undergo large deformations without breaking while Acrylic cannot. Polycarbonate also can be used for electrical applications because it is a great insulator. It also has great safety properties due to it being flame retardant and because it has good heat resistance. Another way Polycarbonate exhibits its safety properties is through bullet resistant glass. Polycarbonate is the most commonly used material for bullet resistant glass, riot shields and face masks. In these situations, the Polycarbonate has a very high impact strength which is invaluable. It protects and saves lives and is able to stand up to abuse in dangerous situations.Polycarbonate Eye Protection Goggles

Polycarbonate Has Many Uses

From audio CDs to Blu-ray discs, airplane canopies to protective eye gear, Polycarbonate is a great thermoplastic (a material that can be formed and returned to its original shape) material for many different applications. Because of its impact strength and wide range of uses, Polycarbonate makes an ideal material for those who need peace of mind when designing or fabricating and need it to hold up to abuse and be virtually unbreakable. Polycarbonate is one of the toughest plastic materials around and everyday new products are being made from it. Whether using it for electrical, optical or for its impact properties, Polycarbonate is an ideal choice for many plastic needs.

Polycarbonate sheet (Makrolon) is available from .032″ – .500″ thick

Polycarbonate Plate, Slab, Block is available up to 4.0″ thick

Polycarbonate Rods are available from .250″ – over 8″ diameter.

More information on the UL approval ratings of Polycarbonate Sheets Here.

Not all Polycarbonate Sheet or Plate meet all approval ratings. Zelux Polycarbonate Plate is available in a machine grade and an optical grade. Zelux Polycarbonate Rod is also available – as a machine grade rod – not optical.
