Product Features

1. Excellent high temperature resistance
Wide range of temperature resistance: long-term resistance from -260°C to 800°C, short-term resistance is even higher (melting point 1450°C), far more than ordinary glass fiber (E-glass).

Fireproof and heat insulation: no harmful gases are released under high temperature, suitable for fireproof boards, heat insulation layer of high temperature pipelines, etc.

2. Strong corrosion resistance
Excellent acid and alkali resistance: stable performance in acidic, humid or salt spray environments, with a longer life than glass fiber (e.g. chemical storage tanks, marine facilities).

Anti-aging: UV resistance, good weather resistance, suitable for long-term outdoor use (e.g. wind turbine blades, building facades).

3. High strength and light weight with good reinforcing effect
Strength close to S-glass fiber: tensile strength 3000-4800 MPa, improving the impact resistance of composite materials.

Lightweight: density is only 2.6-2.8 g/cm³, lighter than metal, helping automobile and aviation parts to reduce weight.

Uniform reinforcement: short-cut fibers are randomly distributed, reducing material anisotropy and adapting to complex structures.

4. Both environmental protection and economy
Green material: the raw material is natural basalt, no boron and other harmful substances, low production energy consumption, recyclable.

Cost-effective: better performance than glass fiber, lower cost than carbon fiber, low comprehensive maintenance costs.

5. Wide process adaptability
Easy processing: good wettability with epoxy, polyester and other resins, support for hand lay-up, spraying, molding and other molding processes.

Fast layup: short-cut mat structure simplifies operation and improves production efficiency (e.g. ship and automobile parts manufacturing).
