5 Must-Have Features in a chopped fiberglass for concrete

I used this in my cast in place kitchen counters. Before I poured the counters we poured 2 - 1'x2' color sample pieces 2 inches thick. I wanted to test the finished color and made sure I added this and the plasticizer to the mix for the samples. No regard or mesh at all. Once cured just to see, I dropped one of the samples flat on the ground from 6 feet in the air, not a single crack, at 2 feet wide I set it across a couple of 2x4's and I can stand on it at 250lbs with no problems. Once poured in the counter top very few of the fibers showed up on the surface when I polished it. Very happy with these.

How Fiberglass is Made

There are a lot of interesting ingredients that go into the successful creation of fiberglass. It&#;s a fantastic example of a composite material. The blend usually features certain measurements of the following materials: limestone, silica sand, soda ash, borax, magnesite, nepheline syenite, feldspar, kaolin clay, and alumina. Glass is also essential, and resin is often thrown into the mix, too.

After you have the right weight and measurements of each ingredient, you&#;ll blend them and place them into the furnace for melting. This process creates molten glass that can be cut into fibers and wound up and lengthened into long filaments or chopped up and used in sheets, insulation, or coatings. 

Once it&#;s created, fiberglass typically has a density of between 2.4 and 2.76 g/cm3. The time it takes to manufacture will depend on the type of fiberglass you&#;re using, what application it&#;s being used for, how long it takes to cure, and the quantity being made. 

Why it&#;s an Important Material in Manufacturing

You might be wondering why manufacturers would choose fiberglass over something else. There are a few reasons that make it a solid choice. Fiberglass is lighter but stronger when it&#;s up against other materials. It&#;s also completely fine when facing harsh conditions, and it won&#;t buckle or warp. These helpful perks are why you could use it for both a pool and a circuit board.

The Different Types of Fiberglass

Your choice of fiberglass isn&#;t limited to one or two types. There are many different kinds, so we&#;ve broken down the basics of 12 of them below to help you choose which will serve you best.

1. E-Glass Fiber

It&#;ll come as no surprise that E-glass or electrical glass, is superb for insulating electrical components. You&#;ll find it used in aerospace and industrial products because it&#;s lightweight and heat resistant. The concoction you&#;ll need for this type of fiberglass includes silica, soda, potash, lime, boric oxide, magnesia, and alumina. 

2. D-Glass Fiber

When you&#;re working with electrical appliances, optical cables, and cookware, you&#;ll want to rely on D-glass fiber. It can insulate these types of items because of its low dielectric constant. The star ingredient in this type of fiberglass is boron trioxide.

3. R-Glass Fiber (Also Known As T-Glass or S-Glass Fiber)

Fiberglass already offers a pretty impressive resume of characteristics, but if you need something that performs even better, R-glass fiber is the one. You also might find it by the T-glass or S-glass, and because of its acidic and tensile strengths, it&#;s usually found in products made for aerospace and defense industries.

4. A-Glass Fiber

This type of fiberglass is one you may come across in your everyday life. A-glass also goes by soda-lime glass or alkali glass, and it&#;s often turned into bottles, jars, and window panes. It&#;s relatively cheap compared to other options, has chemical stability, and you can recycle it. In its mixture, you&#;ll find lime, alumina, dolomite, soda, silica, and sodium sulfate.

5. Advantex Glass Fiber

Advantex glass is trademarked, and it&#;s a version of the material you&#;d look to if you&#;re worried about corrosion caused by acids and temperature changes. That&#;s why it&#;s popular for manufacturers in the mining and oil industries. It&#;s also found in places with the harshest and grimiest conditions, including power plants and sewage systems. You can expect to find a lot of calcium oxide in its makeup.

6. ECR Glass Fiber

If you&#;re after something similar to E-glass fiber but with extra heat and acid resistance, ECR glass fiber is the next step up. It&#;s an environmentally friendly fiberglass that&#;s great if you&#;re looking to make durable panels that can handle water, heat, and impact without struggling.

7. C-Glass Fiber

C-glass also goes by chemical glass, and as you&#;d assume, it&#;s the perfect fiberglass if you need materials that are impact and chemical-resistant. The calcium borosilicate in its makeup won&#;t let you down if you use it in environments (like pipes and tanks) that are exposed to water and chemicals.

8. Z-Glass Fiber

When you&#;re in need of a fiberglass that can provide heavy-duty reinforcements for concrete and other materials, you can look to Z-glass products like mesh. These have no problem handling acids, salt, wear and tear, and UV rays.

9. S2 Glass Fiber

This type of fiberglass is unique in that it can support you with reinforcing textiles. It&#;s a high-performing pick with unbeatable temperature resistance, compression, and impact resistance. You can even make aerospace cloth with it. 

10. AR-Glass Fiber

You may also call AR glass alkali-resistant glass. It gets mixed in with concrete to prevent or at the very least slow down cracking. This flexible fiberglass is strong and won&#;t falter if you need a material that won&#;t succumb to water or changes in the pH. To get it to this level, it has zirconia in its blend of ingredients.

11. M-Glass Fiber

Fiberglass may not sound like it could be truly that flexible, but M-glass fiber will happily prove you wrong. It has plenty of elasticity and beryllium in its formulation, which means it&#;s a great option for making tableware, glassware, packaging, housing, and building materials. 

12. AE Glass Fiber

Just when you thought there couldn&#;t be any more applications for fiberglass, the AE glass type arrives. It may sound niche, but it&#;s a popular material for monitoring and filtering air. Its fibers cut down and trap unwanted particles without completely slowing down its flow rate. Whether you work in a lab or an environmental sector, you&#;ll probably be aware of this type.

Available Formats

Here are the most common formats you&#;ll want to be aware of when it comes to fiberglass.

1. Woven fabrics: Fiberglass can come in a fabric format, which may be unexpected if you&#;re used to hard fiberglass products. You can find it in satin, twill, and plain weaves and can choose based on the finish you&#;d like. This kind of material is great for surfboards, boats, and car parts.
2. Chopped strand mat: Also known as CSM, you can find this thick version of fiberglass particles bound up together in rolls. It&#;s usually tapped on for lay-up and spray-up processes or any situation where you need strength and the ability to wet. 
3. Tow and roving: If you&#;ve worked with fiberglass before, you&#;ll probably be familiar with tow and roving. You can manually unravel these spools or feed them through machines to create parts for aerospace, marine, automotive, or construction industries. 
4. Veil mats: These mats are thin and lightweight, which makes them a great selection if you want to make composite panels, automotive parts, or anything where corrosion is possible.
