some plastics are and some aren't :)
As a general rule, the thicker, denser, and harder the plastic, the more likely it is to be nonporous
Plastics that are elastic, moldable, easily broken, think and lack density and toughness will be porous, for example, saran wrap or grocery bags
What else can I help you with?
What are the elements that are used for plastics to shield Bremsstrahlung?
Plexiglas and lead are frequently used.
What is the difference between hard non-porous surface and soft non-porous surface?
I was curious as to the exact definition of these porous and nonporous because every time I picked up a cleaning supply it would always mention something about whether the product could be used on one or how to treat the area differently depending on whether it was one versus the other. Interestingly enough, a simple google search proved to be much more mystifying and arduous than I would have ever imagine because there was no straightforward answer and all the links characterizing porous v nonporous surfaces were mostly from scientific journals or .edu sites. But to be as concise and brief as possible, from what I gathered, there are a wide array of factors and characteristics to consider for any given material to determine porosity but the main gist is: Porous surfaces are anything that can be penetrated into beyond its outer surface due to either small or narrow spaces which allows absorption, low density, etc. It is porous, or not impermiable. Water, or any other liquid can pass through, for example. Nonporous surfaces on the other hand tend to be thick, dense, and solid do that nothing can permeate it beyond its outer-most surface. Examples of porous and nonporous materials: Porous: fabrics, unvarnished (unfinished) woods, cotton, carpeting, and unsealed tiles (depends on tile type but most need laminate) Nonporous: solid plastics, metal objects (stainless steel, aluminum, chrome, etc), glass of all forms, ceramic surfaces like dishes etc, varnished wood, laminate counters, granite, and vinyl
When was plexiglass invented?
Plexiglas was discovered by Walter Bauer and Otto Rohm of the Rohm and Haas company in Germany in 1933. some people, mostly Canadians, claim that William Chalmers discovered Plexiglas at McGill University, while a graduate student. He actually worked with an inferior plastic called poly(ethyl methacrylate) at a later date. Detailed references to the history of Plexiglas are available at the following link: https://sites.google.com/site/hjhatua
How do you get scratches out of glass and Plexiglas?
To remove scratches from glass, you can use a glass polishing kit with cerium oxide. For Plexiglas, try using a plastic polish or a mild abrasive, such as toothpaste or baking soda mixed with water. Apply the product to the scratched area and polish in a circular motion until the scratch becomes less noticeable.
Can you put acrylic in the freezer?
Acrylic is the word for any of a number of plastics. Probably the most widely-known acrylic is Plexiglas. You can put them in the freezer if you like, but they will be more brittle when cold.
Is stainless steel a nonporous surface?
Yes, we generally consider stainless steel to be a nonporous surface.
What is a Plexiglas box?
A plexiglas box is a light transparent weather resistant thermoplastic container.
Why do water droplets always form one huge drop on a penny?
Surface tension of water draws it into a larger drop. It will do that on any nonporous surface- metal, glass, smooth plastic, etc.
Is leather porous or nonporous?
Leather is porous unless the surface has been waterproofed. Dubbin is one product that is frequently used to waterproof walker's boots.
What is the density of plexiglas?
The density of plexiglas is rho = 1,190 kg/m³ or rho = 1.19 g/cm3.
What are the advantages of Plexiglas compared to that of normal glass?
The advantages of Plexiglas compared to that of normal glass are first that Plexiglas cost a fraction of the price, second it is very durable and wont shatter like glass.
Is drywall nonporous?
Drywall is VERY porous .
Who has the trademark on Plexiglas?
Plexiglas was registered in 1935 by Delaware company Rohm & Haas, and appears to be owned by a French company called Arkema. The most recent related registration, for Plexiglas Edge FX in 2005, was by Arkema directly.
Can you use a squeegee on plexiglas?
Yes
What do you use to tint plexiglas?
Paint
How do you remove permanent marker from plexiglas?
Rubbing alcohol as soon as possible. Plexiglas is a bit porous and the die can get into it if left for any length of time.
How do you rid a hot tub of black mold?
The easiest way to clean a nonporous surface of black mold is to scrub it off with a solution of 1 cup of borax to 1 gallon of water.
