Basaltex

Company Profile

Basalt fiber is spun from volcanic rock, and its textile value is thermal: basalt fabrics tolerate sustained high temperatures without burning, which is why they are woven into fire-barrier interliners — the hidden layer inside aircraft seats, public-transport seating, theatre and contract upholstery, and protective assemblies that must pass flammability tests as a composite. The record's two series divide the offer: the 7101 Fire Blocker range across five weight/width variants, and the 7112 series as the abrasion-resistant fire-barrier interliner line.

The Belgian base matters: Masureel is a long-standing Flemish textile finishing group, and Wevelgem sits in the West Flanders textile region. Technical textiles of this kind are sold on test performance rather than appearance, so the record reads like an engineer's document — densities, widths and series numbers instead of fabric names — because its readers are seat and upholstery manufacturers qualifying a barrier layer against a named flammability standard.

The series numbers in Basaltex's record are a specification language: the 7101 Fire Blocker family lists variants from 7101.20.10 through the newer 7101.75.17, encoding density and width steps between 210 and 750 g/m2 and 1 to 1.74 m, while the 7112 family covers abrasion-resistant barrier interliners. Basalt itself is the story behind the numbers — a fiber drawn from molten volcanic rock, inherently non-combustible, needing no chemical flame-retardant finish to do its job. That permanence is the selling point against treated fabrics whose performance can wash or wear away: the barrier is the fiber, not a coating.

Sourcing and Working With Basaltex

Sourcing a fire-barrier interliner starts with the end product's test standard: the barrier is qualified as part of a composite (foam, interliner, outer fabric), so buyers should share the standard they must pass and ask which series and density the maker recommends for that construction. The recorded range — 210 to 750 g/m2, widths of 1 to 1.74 m — lets the barrier be matched to the seat or panel size without excessive cutting waste.

Ask for test reports on the exact series under consideration, and confirm how the fabric behaves in making-up: basalt fabrics are cut and sewn differently from conventional cloth, and edge fraying and needle choice are practical questions the maker can answer from application experience. Because these are safety components, also agree the traceability and batch documentation your own compliance file will need.

Understanding the Range

Technical textiles are bought on performance data, not on appearance, and Basaltex's field — 'Basalt fire-blocking and fire-barrier interliner fabrics (Fire' — is no exception. The professional approach is to start from the standard the end product must meet, work backwards to the material properties that decide it, and ask the maker for test evidence on the exact product variant being bought. Documentation is part of the product in this family: batch traceability, test reports and application guidance are what a buyer is really paying for alongside the material itself, because the material disappears inside a larger product whose safety or function may depend on it.
