Because they are thermosets, no melting will occur with these grades, however charring will be observed after extended periods above this temperature rating. A PDF that explains the effect of bromine on epoxy materials and potential applications. G10 material is some of the strongest materials out there. And, has amazing properties that cannot be touched by other resins. If you are looking for a material that will last, then G10 material is an option.

Low Absorption

Properties for G-10CR are available from this database; unfortunately, properties of G-11CR are not. Most cryogenic texts (Ref. 2, for example) contain data on “G-10”. Reference 1 contains information on the material properties of G-11CR. If any of our readers have a source for G-11CR property data at cryogenic temperatures we would be interested. Its dimensional stability combined with temperature tolerance, chemical resistance, superior strength, and lightweight makes it a go-to material. The aerospace industries, heavy equipment, and the automotive industry use G10 a lot in their applications.

You know, those cool green boards in the back of your computer. But, this marvelous material has a life that can extend far beyond those circuit boards. NIST maintains an online database that includes the cryogenic material properties of G-10CR. Data for cryogenic material properties of G-11CR are not as readily available.

Our people value honesty, integrity and other family values that are often missing in newer or larger companies. Epoxy resin is flammable and, once set on fire, will burn violently, giving off poisonous gases. Therefore similar materials like FR-4 containing flame retardant additives have replaced G-10 in many applications. Want to learn more about our G-10 handles and products to see how they can be used for industrial applications?

This material has a super high strength that stops it from bending or breaking under load. It doesn’t absorb moisture even when exposed over time and oil doesn’t bother the G10 material. These are some extremely strong and desirable properties for many applications. The material is similar to cutting sheet metal and offers very little heat expansion so getting the blade a bit hot will not affect the cut at all. Another variation of G10 fiberglass sheet is G10 CR laminate used in cryogenic applications. The minimum glass transition temperature is an important design criteria for many structural applications.

Created by the stacking of multiple glass cloth layers. Then by heat and pressure, it is compressed into the shape you are looking for. As with most fiberglass, this g 10 material stacking provides amazing strength and durability. This is a very popular and strong material used in many industries in custom fabrication for good reason.

G10/FR-4 Glass Epoxy Glass/epoxy composite material with outstanding electrical properties. The material must have custom fabrication and it is not an injection molding type of material.

G10/FR4 has extremely high mechanical strength, good dielectric loss properties, and good electric strength properties, both wet and dry. G10/FR4 are widely used in the electronics field – primarily because water absorption is virtually nil, rendering it an excellent insulator. Because G10 has little water absorption using it in and around boats is a great option.

We like G10 for its great properties and are sure you will too. Which is used in most boating applications, however, it’s not as widely used. This is because very few people are aware that G10 is far less costly and has virtually the same properties. https://1investing.in/ G10 does break down in UV light, so if it’s a component that is exposed to the sun, not a good idea. However, all those other places on a boat that needs backing plates and such, you have found the best product for such an application in G10.

Today what is called G10 composite is actually FR4, the Brominated flame retardant version of G 10. The FR 4 material can usually be used where G10 material is specified, however G10 Laminate should not be used where FR-4 is specified. When cutting and grinding give care to protect your skin and airways. It will not rust or oxidize, won’t become brittle, and will not soften over time.
