Basically the linear polarized film sheet structure is by 3 layers material; polarizing membrane PVA (Polyvinyl alcohol) and support layers TAC (Tri-acetate cellulose) on its both sides.
It is the most commonly used for additional protective film or release film with self-adhesive backing.
3Dlens have passed a linear polarizing test for durability 60°C / 90%RH / 500 Hours, so it is a good replacement for Polaroid and 3M HN32 & HN38.

The earliest artificial polarizer was invented by Polaroid company Edwin H. Land in 1928. Although it has 90 years of history, but the process principle and material are still roughly the same.
Polarized films are widely used in research labs, the optical industry and equipment. Commercially available polarizers are made from different materials such as glass, crystal or plastic.
Plastic polarizer films are the least expensive and commonly used in liquid crystal display such as screens of calculators or computer monitors, polarized sunglasses, and 3D movie glasses.
Protective film used to protect the polarizing plate surface, consumers need to tear the film when use a polarizer.
Onto this bare polarizer, additional treatments are applied such as an adhesive glue, hard coating, antiglare, anti-reflection and other surface treatments.
At present there are two types of polarizers in the market: iodine polarizing film and dye type polarizing film
The general process, the first is to produce a polarized film, hydrophilic PVA. After the film is swollen, it is immersed in a dichroic dye solution and stained.
The dichroic dye is usually a solution of iodine and potassium iodide. And then extend the dyeing film, extending to give the Dichroic dye arrangement, the higher the order, the prepared polarizing film optical properties are better.
After the extension of the film after drying, easy to stretch the direction of brittle fracture.
The iodine polarizing film has a high permeability, high contrast and a wide range of wavelength bias characteristics, the price is relatively cheap, so for a wide range of applications.
The polarizing property of the dye-based polarizing film is inferior to that of the iodine system, but the wet heat resistance characteristic is good and belongs to the durability polarized film.
Iodine standard linear polarizing film applications is in a wide range, such as watches, calculator computers, PC, OA machines. In addition, cars, ships, aircraft, outdoor measurement equipment for the use of dye-based polarizing film such a durable polarizing film.
Light is an electromagnetic wave, the general light in the forward, the electromagnetic vibration direction in all directions. If the electromagnetic vibration occurs only in a plane, that is, the direction of the electric field vibration and magnetic field direction fixed light is called polarized light. The direction of its electric field is called the polarization direction of light.
It is through the electromagnetic or mechanical action to have dichroic acid quinine sulfuric acid small crystals neatly arranged in a transparent plastic film made of.
Artificial polarizer as a result of a simple manufacturing process, cheap, and can be made into a larger area, which has been widely used.
At present in the general polarization instrument and many of the partial and the partial detection device using artificial polarizer.
For example, when watching a three-dimensional movie, the audience needs to wear a pair of glasses, which is a pair of vibration perpendicular to each other polarized film.
The principle is that we usually only use two glasses to see the object to produce three-dimensional sense, if the use of two shots, such as the human eye, from two different directions at the same time takes the film scene image, made positive film.
In the projection through the two projectors with the vibration direction perpendicular to each other, two linearly polarized light superimposed on the screen, the human eye through the above polarized glasses to watch, each eye can only see a corresponding independent image, Like a direct view to produce a three-dimensional feeling.
Manufacturing of plastic polarizers:
Polarized film is created from rolls of polyvinyl acetate (PVA). The process begins by heating and stretching PVA to a much longer and thinner sheet.
This lengthens PVA's long chain molecules, causing them to align. The stretched PVA is then dipped in iodine solution.
The iodine is absorbed into the molecular chains forming long grids of parallel and darkened lines. The film is then dyed to the color of the desired finished film.
The darker the film, the more polarization it provides. Once the PVA is dyed and dried, it is delicate and hard to handle. To stabilize it, the film is mounted on a sheet of cellulose acetate butyrate (CAB).
Here are some reviews from our customers:
These polarizer sheets arrived packed very securely so they could not get warped in the post. The company processed my order very quickly and provided good tracking information. The polarizer sheets work very well and I'm hoping that I can use them to repair an old graphics LCD module if I can get the residue of the old polarizers off it. Bob (Australia)
Hey mate, the linear polarising film you kindly sent me worked perfectly to repair the digital display on my motorbike. Rob G (Australia)
We have been ordering from you for years, for our science kits. Thank you for your good polarizing filters! Briana (Washington, United States)
Many thanks for the ultra fast delivery (4 days) and the very well working polarizers, quality is much better than ever expected! Stefan (Germany)
Your polarizing film is higher contrast and works better for the art. Austine (United States of America)
I ordered the polarizer from your website, and am really happy with its performance. Micro (American)
Polarizer film is excellent, shipment was quick and packaging is excellent. Andrew (USA)
We evaluated your A1 & A4 polarizing filter. They performed very well... Haozhe (United States)
Your polarizing film adhesive has passed our R&D test... Sylvia (China)
I am really surprised how the fine #P200A polarizer works with my mp3 player. Peter (Czech)
I purchased previously your linear polarizer. They work very well in a polarizing microscope. Andres (Spain)
Your polarizer film has excellent extinction and transmission properties and appears to be a cost effective solution for its size and price compared to Polaroid HN22 product. Neil (USA)
Transmission and efficiency are OK. They do the job very well. Bernard (Australia)
Polarizing filter #P210 is performed in my application even better than 3M HN32 Polaroid film. Vlad (United States)
I want to do an inversion of the display monochrome LCD in the vehicle. What kind of film should I use to get a high quality inversion?
Answer: You need a linear polarizer film with/without adhesive to replace the old film.
At our hospital, we are building two glass walls, which are on opposing sides of the nurses station, each glass wall with polarizing film adjusted so that a nurse could see out into each of the patient areas, while a patient in either of the patient areas could see into the nurses station but not through to the other patient area.
Answer: Yes, it's possible to achieve your requirement. You can place one piece of polarizer film 0 degree and place another piece on the other side 90 degree. When two pieces at the same angle, you can see through them. When they are 90 degree across from each other, they become black and it's hard to see through them.
What is the difference between P620 and P620A polarizer film?
Answer: The only difference is whether there is adhesive glue
Is your linear polarizer film roll same as P620?
Answer: Yes, the specification and function are the same as the sheet polarizer P620. We will provide roll film in roll length from 3M to 10M without cutting.
