InduBarrier Type 4B is a high-performance protective fabric for extreme industrial and medical environments. It combines waterproof protection, chemical splash resistance, breathability, and antistatic properties to ensure safety and comfort in demanding applications like chemical handling and emergency response. Certified to CE Type 4B and EN 14126, it offers superior barrier performance and durability for high-risk industries.
InduBarrier™ Type 4B is engineered for protective garments used in environments involving directional or sustained liquid chemical spray exposure, contaminated liquids, and biological hazards.
Its microporous breathable film and nonwoven composite structure provides a barrier against liquid spray and contaminants while allowing moisture vapor generated by the wearer to move outward.
Representative material constructions combine spray protection, breathable moisture management, mechanical durability, and garment-conversion flexibility for demanding industrial protective applications.
InduBarrier™ Type 4B combines spray-tight protection, breathable moisture management, biological barrier performance, mechanical durability, and antistatic options for demanding protective-garment applications.
InduBarrier™ Type 4B is developed primarily for spray-tight liquid protection. Kae Hwa’s Type 4B protective garment platform has also been tested and verified for Type 5B and Type 6B requirements.
In practical garment selection, this verified protection coverage allows the InduBarrier™ Type 4B platform to support a broader range of industrial exposure conditions.
Type 4B, Type 5B, and Type 6B remain separate complete-garment classifications. Buyers should confirm that the supplied garment model and certification documentation cover the stated protection types.
Type 4 refers to spray-tight protective clothing intended for environments where liquid chemicals may reach the wearer through directional spray, mist, or repeated droplets.
The suffix “B” indicates protection requirements related to infective agents under EN 14126.
Type 4B is a complete-garment classification. Final performance depends on the protective fabric as well as seams, zippers, cuffs, hood construction, closures, openings, and sealing methods.

It is engineered for high-risk industrial and medical applications, including chemical handling, asbestos removal, biohazard cleanup, and emergency response.
It is fully certified to CE Type 4B, 5B, and 6B for liquid spray and particulate protection, EN 14126 for biological hazards, and EN 1149-5 for antistatic safety.
Yes. The microporous structure maintains a moisture vapor transmission rate (WVTR) of 2,000–5,000 g/m²·24hr, allowing body heat to escape while providing a reliable liquid-tight barrier against toxic spills.
Meeting EN 1149-5 standards, the fabric prevents electrostatic discharge. This is a mandatory safety feature for preventing sparks in explosive or highly flammable chemical environments.
We offer customizable basis weights (43–100 gsm), thicker profiles (180–300 μm) for extreme durability, and industrial color options including Khaki and Black, alongside specialized anti-static or printing surface treatments.
