High silica chopped strands is cut and processed by high-silicon glass fiber yarn, known for its high temperature resistance, ablation resistance and corrosion resistance. It has gradually substitute for asbestos and ceramic fibers and becomes the main thermal insulation material. These chopped strands are composed primarily of silica and offer remarkable resistance to extreme temperatures, making them invaluable across various industries. High silica chopped strand can be directly used as insulation filling material, to produce high-silica needled felt and high-silica wet-laid felt and as a reinforcing material mixed with organic resin to make ablation resistant bodies, such as missile heat insulation cover etc.
Feature:
- High Temperature Resistance:
The high silica content provides better resistance to heat, making it suitable for use in environments that are exposed to extreme temperatures.
- Enhanced Corrosion Resistance:
The silica coating on the strands offers additional protection against chemical corrosion, enhancing the durability of the composite materials.
- Good Mechanical Properties:
When incorporated into composite materials, high silica chopped strands improve mechanical strength, stiffness, and dimensional stability.
- Electrical Insulation:
High silica content can contribute to better electrical insulation properties, making these strands ideal for certain electrical applications.
Application:
- Reinforced Plastics:
Used in automotive, construction, and consumer goods where high-strength, lightweight materials are needed.
- Composites:
Used in the aerospace and marine industries for creating composite materials that require both strength and heat resistance.
- Electrical Insulation:
Incorporated into cable insulation and other electrical products.
