Nelcote E-718 Epoxy Prepreg, 7781 E-Glass Reinforced

Have you ever heard of this product used in the construction industry? It is a new type of e-glass whose strength and weight have made it essential in leading industries. Yet, today, many companies still struggle to find ways to protect their money-making infrastructure due to its high demand. Here, we’ll get into all the details about this product, including what makes it stand out from other products on the market.

What is the Nelcote E-718 Epoxy Prepreg, 7781 E-Glass Reinforced?

The product is basically what its name suggests – an e-glass that has been formulated with epoxy. This means it’s an e-glass with epoxy infused within it. Ever wonder why this product is so important? It encompasses everything that makes the traditional, unformulated type of e-glass hard to use.

Nelcote E-718 Epoxy Prepreg, 7781 E-Glass Reinforced is a polyester fabric or fabric made from polyester. When infused with epoxies, this fabric becomes so flexible that we can easily mold it into any shape or form. This is the main reason why this product has been helpful in construction.

The traditional e-glass products don’t have this flexibility and can be flimsy, making them more challenging. Therefore, Nelcote E-718 Epoxy Prepreg, 7781 E-Glass Reinforced, has been such a welcome addition to the construction industry. It’s perfect for making different types of patterns and designs, making it possible to build more complex shapes and create simply stunning architectural fashion.

E-Glass: The Word Explained

Ever heard of e-glass? Indeed, you may have; after all, there are many kinds of glass. The most common kind of glass is common, or crystalline, which has different forms such as crystal, flake, etc. There are other kinds of glass too.

However, one type stands above the rest in terms of strength – e-glass. The e-glass is a special kind of glass that doesn’t have any natural minerals such as mineral oil. This means that there are no impurities in e-glass, meaning that it’s not easily scratched or damaged. As a result, it doesn’t break easily, and it won’t ever shatter in your hands – a trait that is perfect when dealing with glass in the construction industry.

What makes e-glass so special? It consists of pure silica fibers. These silica fibers mix with binders and then poured into molds to make specific forms. The different shapes that the e-glass can produce include plates, rods, tubes, rounds, and similar items. There are many variants of e-glass that have different properties or colorations.

E-Glass: What You Can Do With It in the Construction Industry

Why is it so necessary to use e-glass? First, it was to help improve the strength and durability of buildings, especially in construction. Many of these buildings consist of concrete, which can easily break if we expose the concrete to sunlight. Therefore, e-glass is essential because we can use it as a lightweight alternative to solid concrete.

What made it so groundbreaking?

It’s much cheaper to use e-glass in construction than other materials, primarily because of its lightweight. In addition, it doesn’t have the same maintenance requirements as concrete does, which makes keeping the infrastructure strong and stable a breeze.

This product has also been used in automotive engineering to make fiberglass boats and yachts. It’s even been helpful to make air cushions for cars and boats; it makes them as strong as concrete. It’s also beneficial in making lampshades and ballasts for electronics.

E-Glass: What Makes It Different from Other Glasses

E-glass has become so popular because of its cost-saving factors. In addition, it doesn’t require a lot of maintenance, which means that the infrastructure can stay intact without the need to repaint all the time while we can easily repair it if there are any chips or scratches.

It’s also very versatile. We can use it anywhere and easily shape it into any form, which has become so popular in the construction industry. In addition, it’s much easier to mold than cinderblock, which is why it has been helpful as an alternative. It can even create walls and roofs that resemble concrete. Therefore, e-glass still has a long way to go before it completely replaces concrete in the construction industry.

The benefits of using e-glass in the construction industry are endless. With both its strength and flexibility, it’s easy to mold into any shape and form it needs to be. However, it still needs a lot of research to become even more cost-effective, so people must continue investing in this product if they want to see their infrastructure last for much longer than needed.


Physical Properties

1. Volatiles: The glass is not volatile. Therefore, it does not burn or melt. We can measure the physical properties of the glass by calorimeter (temperature, conductivity, and density). It is <= 1.0 % at Temperature 135 °C.

2. Thickness: The glass can be formed in different thicknesses, 0.3mm to 20mm, depending on the customer’s request. The ideal thickness is 229 microns.

Mechanical Properties

1. Tensile Strength, Yield: The tensile strength of the glass is 738 MPa at a Temperature of 82.2 °C

2. Tensile Modulus: The tensile modulus is 417 MPa at a Temperature of 82.2 °C

3. Flexural Strength: The flexural strength is 1170 MPa at a Temperature of 23.9 °C

4. Flexural Modulus: The modulus of elasticity is 44.8 GPa at a Temperature of 23.9 °C

5. Compressive Strength: The compressive strength is 820 MPa at a Temperature of 82.2 °C

6. Compressive Modulus: The modulus of elasticity is 43.4 GPa at a Temperature of 23.9 °C

7. Shear Strength: The shear strength is 93.8 MPa at a Temperature of 23.9 °C

Thermal Properties

The Glass Transition Temp, Tg is -165 °C. We obtain this value by Differential Scanning calorimetry (DSC).

Key Features and Benefits

1. Good mechanical properties at high service temperatures: The glass has good strength and Young’s modulus of elasticity. So, we can use it at service temperatures from -40 °C to 150 °C in applications such as hot plates, heaters, and conductive glazing.

2. 250°F cure epoxy system: The glass can be cured at a specified temperature (200°F) using a 250°F epoxy system.

3. Excellent thermal and mechanical properties: The glass has excellent thermal and mechanical properties as a heat retaining material. It has better strength than 6061-T6 aluminum alloy and 3/8-inch mild steel sheets, with similar thermal conductivity to B70 acrylic resin.

4. High tack, high flow prepreg: Low resin content, up to 12 plies. Low shrinkage. So, we can easily handle it in the fabrication process.

5. Excellent handling characteristics and out-time: Low resin content, up to 12 plies. Low shrinkage.

6. Good low-pressure consolidation: We can easily cut the glass with low-pressure consolidation by using a microwave dryer. The result is a very strong economic sheet with good mechanical properties and high tensile strength.


Recreational Applications

 A wide range of applications where e-glass can be essential includes recreational boats, sporting goods, helmets, and protective gear. In addition, E-glass is helpful as thermal insulation and acoustic padding in vehicles. Finally, it is helpful as a substrate for large LCDs, such as some used in airplanes and automobiles. Additionally, we use it for ski helmets, surfboard blanks, and recreational vehicles.

Industrial Applications:

 E-glass helps make pressure vessels and tanks used for storing liquid, power plants, and nuclear power plants. It’s also helpful to make boats and yachts, watercraft, and even anti-lock braking systems. E-glass is also essential in making fiberglass tanks and bins; they’re often transparent to help as bins or display cases. The material is also necessary for making ballasts for electronics and lampshades.

Optical Fiber:

The material is also helpful in optical fiber cables used for communication, computer networks, and the internet. It’s even helpful in making the protective outer casing for satellites placed in space; the material is resistant to ultraviolet radiation from the sun and temperature fluctuations.


E-glass is a type of glass that’s a lot more durable and flexible than normal glass, making it ideal for those who need better quality tools for their businesses. In addition, it saves the business owner money. We can mold the material into different shapes and sizes to last longer than needed.

Rayming PCB & Assembly use e-glass because of its cost-saving features. It doesn’t require much maintenance, which means they can use the same infrastructure for much longer than needed.
