Basalt Short Fiber

Controlled Fiber Dimensions

For usage in a variety of bonding and composite systems, continuous basalt fibres are chopped to certain lengths to create basalt short fibres.The technical information presented states common fibre lengths of 4.5mm, 6mm, and 10-30mm, although detailed tables mention cut lengths of 3, 6, 13, 15, 18, 25, 27, and 50mm with tolerances of ±1.5mm. With tolerances of ±1.5 μm, the usual fibre sizes are 9, 13, and 17 μm.

Because it enables the choice of fibre size according to the material being reinforced, this range is helpful. According to the information given, basalt short fibres are added to thermoplastics, concrete, asphalt, cement, and combinations based on gypsum. Additionally, it is utilised in substrates, mortar layers, tile adhesives, gypsum, and cement slurry. The fibres enhance the finished product's polish and lessen surface chipping and cracking.

More Than Concrete Reinforcement

Construction is not the only use for basalt short fibres. Applications include pultruded profiles, car body panels, ship hulls, and thermoset composites like SMC, BMC, and DMC moulded parts. Additionally, it is utilised as a thermoplastic reinforcement in nonwoven basalt mats, textiles, high-temperature filter felts, and composites made of PA, PP, HDPE, and nylon.

High mechanical strength, heat resistance, chemical resistance, sound absorption, and dielectric qualities are also mentioned. Sizes can be chosen based on additional processing for applications that need to be compatible with various matrices.

Fibre length, diameter, moisture content, size, and matrix compatibility are important considerations for buyers of basalt staple fibres. Instead of depending on a single standard specification, the product can more accurately resemble real blending or composite processes thanks to the availability of multiple cut lengths and fibre sizes.
