Basalt fiber chopped strands are produced by chopping continuous basalt fiber roving with special sizing protection and compatible with a certain basis material.

Pasia Industries offers a special type of basalt chopped fiber, compatible with various general purpose resin systems such as epoxy, phenolic, vinyl ester and polyester. Basalt chopped strands are mainly recommended for the manufacturing of friction materials, reinforcing concrete and bitumen, BMC or SMC material, making chopped strand mat, needle mat, etc Special sizing formulas can also be provided for other application requirements.

General Specifications

Increasing performance of friction material:

Basalt fiber is an eco-friendly, high-performance reinforcement for friction materials (brake pads, clutches), offering superior wear resistance, thermal stability, and low noise compared to asbestos or steel. Its high-temperature resistance and stable friction coefficient make it an ideal, sustainable alternative for enhancing frictional performance and durability in automotive applications.

Key Advantages in Friction Materials:
High Thermal Stability: Basalt fibers maintain structural integrity at high temperatures, reducing thermal fade in braking systems.
Superior Wear Resistance: Studies show basalt fiber-reinforced materials offer better wear resistance than asbestos, steel, and glass fibers.
Improved Frictional Stability: Basalt fiber reduces friction fluctuations, providing consistent performance.
Environmental Friendly: As a natural volcanic rock product, it provides a green, non-toxic, and non-corrosive alternative to traditional fiber reinforcement.
Enhanced Mechanical Strength: It increases the tensile strength and modulus of organic brake pads.

Applications and Performance:
Brake Pads: Used to improve friction stability and reduce noise.
Clutch Facings: Provides durability under high-stress conditions.
Optimal Properties: Research indicates that using 10 mm length fiber at appropriate content levels yields the best reinforcement for friction composites.

Basalt fiber's ability to withstand high temperatures (up to 900 ℃ in some cases) without losing strength ensures it is highly effective in demanding braking environments.


Concrete improvement

Compared with different types of reinforcing fibers, Pasia Basalt fibers have achieved the best overall technical and economic benefits in fiber-reinforced concrete and maintain a leading position among natural mineral fibers. They are made from short-cut basalt fibers produced by our company. Tests conducted by international research centers and the application effects of the products in actual projects have both confirmed this.

Basalt chopped strands are essential products for:
Eliminate large concrete surface cracks;
Make reinforced concrete structures achieve stability and toughness when bearing different loads;
Reduce the backflow during shotcrete application;
Improve the wear resistance of the concrete surface;
Enhance the frost resistance and waterproof performance;
And accelerate the drying process of large concrete blocks.
