1. What is fiberglass powder
Fiberglass powder, also known as fiberglass powder, is a powder obtained by cutting, grinding and sieving specially drawn continuous fiberglass strands. White or off-white.
2. What are the uses of fiberglass powder
The main uses of fiberglass powder are:
- As a filling material to improve product hardness, compressive strength, reduce product shrinkage, wear scar width, wear, and production cost, it is widely used in various thermosetting resins and thermoplastic resins, such as filled PTFE, increased nylon, reinforced PP, PE, PBT, ABS, reinforced epoxy, reinforced rubber, epoxy floor, thermal insulation coating, etc. Adding a certain amount of fiberglass powder to the resin can significantly enhance various properties of the product, including hardness, crack resistance, It is also possible to improve the stability of the resin binder and reduce the production cost of the article.
- Fiberglass powder has good wear resistance and is also widely used in friction materials, such as brake pads, polishing wheels, grinding wheel pads, friction pads, wear-resistant pipes, wear-resistant bearings, etc.
- Fiberglass powder is also used in the construction industry. The main function is to increase the strength. It can be used as the thermal insulation layer of the outer wall of the building, the decoration of the inner wall, the moisture-proof and fire-proof of the inner wall, etc. It can also be used to strengthen the inorganic fiber with excellent anti-seepage and crack resistance of mortar concrete. Substitute polyester fiber, lignin fiber and other products for reinforcing mortar concrete.
3. Technical requirements of fiberglass powder
Fiberglass powder is a product made by grinding fiberglass, and its technical requirements mainly include:
- Alkali metal oxide content
The alkali metal oxide content of alkali-free fiberglass powder should be no more than 0.8%, and the alkali metal oxide content of medium alkali fiberglass powder should be 11.6%~12.4%.
- Average fiber diameter
The average diameter of fiberglass powder should not exceed the nominal diameter plus or minus 15%.
- Average fiber length
The average fiber length of fiberglass powder varies according to different specifications and models.
- Moisture content
The moisture content of general fiberglass powder should be no more than 0.1%, and the moisture content of coupling agent fiberglass powder should be no more than 0.5%.
- Combustible content
The combustible content of fiberglass powder should not exceed the nominal value plus or minus
- Appearance quality
Fiberglass powder is white or off-white, and must be free of stains and impurities.
