InduBarrier™ Type 5B & Type 6B

Breathable Particle & Limited-Splash Protection for Industrial Safety

InduBarrier™ Type 5B particle and dust defense and Type 6B lightweight limited-splash protective fabrics

InduBarrier™ Type 5B and Type 6B are breathable microporous laminate systems developed for industrial protective garments where protection, mobility, and long-wear comfort must work together.

Type 5B is engineered primarily for hazardous dry particles, fine industrial dust, and airborne contaminants, while Type 6B provides a lightweight protective solution for limited liquid splashes, light chemical aerosols, and paint mist.

Both systems combine breathable membrane technology with nonwoven reinforcement to support barrier performance while helping reduce heat and moisture buildup inside protective apparel.

Particle & Dust Defense

InduBarrier™ Type 5B

Engineered for protective garments used in environments where hazardous dry particles, fine industrial dust, and airborne particulate contaminants are the primary exposure risks.

Particle Control Breathable Durable EN 13982-1
Lightweight Limited-Splash Protection

InduBarrier™ Type 6B

Designed for lightweight protective garments exposed to limited liquid splashes, light chemical aerosols, paint mist, and similar low-intensity liquid hazards.

Limited Splash Lightweight Flexible EN 13034

Shared Core Advantages

Both Type 5B and Type 6B are built around breathable laminate engineering designed to balance protective performance with mobility and wearer comfort.

Breathable Comfort Moisture-vapor transmission helps reduce heat and humidity accumulation during extended protective wear.
Mechanical Integrity Nonwoven reinforcement supports tear, tensile, puncture resistance, and stable garment conversion.
Antistatic Performance Selected material systems support protective clothing designed around EN 1149-5 antistatic requirements.
Biological Barrier Support Representative InduBarrier™ materials are supported by EN 14126-related biological barrier testing.

Two Protection Strategies for Different Industrial Hazards

Type 5B
Inward Particle Leakage Control

Type 5B focuses on limiting the penetration of fine airborne solid contaminants through the protective garment system.

Its breathable microporous structure provides a controlled barrier against hazardous particulate exposure while maintaining moisture-vapor transfer for wearer comfort.

Type 6B
Limited Liquid Splash Repellency

Type 6B is designed for lower-intensity liquid exposure where lightweight mobility is more important than complete liquid-tight protection.

The smooth breathable laminate helps repel light splashes, aerosols, and paint mist while maintaining a soft and flexible garment structure.

Industrial Application Fit

Type 5B — Particle & Dust Applications

Pharmaceutical Powder Handling Protective apparel for operations involving pharmaceutical powders and fine dry materials.
Asbestos & Hazardous Dust Removal Remediation and cleanup work where hazardous airborne dust is a primary exposure concern.
Industrial Particle Cleanup Maintenance and cleaning operations involving fine powders or contaminated solid particles.
Dry-Powder Agricultural Operations Protective garment applications involving dry agricultural powders and particulate exposure.

Type 6B — Limited-Splash Applications

Automotive Painting & Coating Lightweight protective apparel for spray painting, coating, and paint-mist environments.
Industrial Cleaning & Maintenance Everyday maintenance activities where occasional light liquid exposure may occur.
Light Chemical Handling Suitable where protection from limited chemical splashes is required without a liquid-tight garment system.
Pharmaceutical Hygiene Operations Lightweight protective wear for selected controlled production and hygiene-sensitive operations.

Laminate Construction Options

Both Type 5B and Type 6B can be configured using two-layer or three-layer breathable laminate structures according to required strength, comfort, basis weight, and garment design.

2-Layer
Nonwoven + Microporous Breathable Film

A streamlined laminate configuration designed to reduce overall material weight while maintaining the required barrier and mechanical properties.

3-Layer
Nonwoven + Microporous Film + Nonwoven

Adds structural support and an additional textile layer for demanding garment constructions where durability and handling stability are important.

Construction Note: InduBarrier™ Type 5B and Type 6B use 2-layer or 3-layer laminate constructions. A 2.5-layer structure is not part of these protective fabric systems.

Protective Standards & Performance

InduBarrier™ Protection Level Comparison

Type 5B focuses on hazardous particle and dust exposure, Type 6B provides lightweight limited-splash protection, while Type 4B is intended for more demanding liquid spray environments.

InduBarrier™ Type 4B vs Type 5B vs Type 6B protective fabric comparison
Classification Note: Type 5B and Type 6B are classifications applied to complete protective garments. Final compliance depends on laminate performance as well as garment construction, seams, closures, openings, connection points, and applicable whole-garment testing requirements. Final product selection should therefore be confirmed against the relevant material test reports and garment certification documentation.

Redefining the Boundaries of Breathable Technology

Understanding Type 5B — The Benchmark for Particulate Defense

Under CE PPE regulations, EN 13982-1 (Type 5) specifies performance requirements for chemical protective clothing providing protection to the full body against airborne solid particulates. The critical metric here is preventing "Total Inward Leakage" (TIL) of fine dust. InduBarrier™ Type 5B goes beyond basic requirements by ensuring the membrane's micropores are strictly controlled to block microscopic solids while maintaining essential vapor diffusion, offering uncompromising defense for hazardous material handlers.

FAQ

Type 4B materials are engineered to be liquid-tight, protecting against heavy chemical sprays and liquid aerosols. Type 5B materials, like this specific InduBarrier™ fabric, are designed to block hazardous dry particulates (such as toxic dust or asbestos) and airborne biological aerosols while maximizing breathability.

Industrial workloads raise body temperature quickly. InduBarrier™ Type 5B uses a microporous film that allows water vapor (sweat) to diffuse through the fabric. This continuous venting mechanism cools the worker naturally, extending safe working hours and reducing the risk of heat-related illnesses.

Yes. When appropriately converted and seam-sealed into a garment, our fabric provides an excellent barrier against biological aerosols and fine chemical powders, making it highly suitable for pharmaceutical manufacturing, cleanrooms, and outbreak response scenarios.
