It’s frustrating to wear protective clothing that feels hot, heavy, or still lets contaminants through. Many people don’t know there’s a better alternative. This article breaks down microporous coveralls in simple terms so you can understand how they keep hazards out while staying breathable. By the end, you’ll know whether this type of suit is the best choice for your job.
What Are Microporous Coveralls Made Of?
Microporous coveralls are made from a special fabric called microporous film-laminated fabric. This fabric combines a nonwoven polypropylene layer with a thin breathable polyethylene film. The film has tiny holes, or micropores, that are:
- 15,000 to 20,000 times smaller than water droplets, stopping liquids and dust from getting inside.
- 250 times larger than moisture vapor molecules, allowing sweat and heat to escape.
This design means the coveralls block liquids, dust, and fine particles while still being comfortable to wear for long periods.
Key Features of Microporous Fabric
Waterproof and liquid repellent: The fabric stops liquids like blood or chemicals from passing through. It meets strong safety tests like ASTM 1670, which checks for blood penetration.
Breathable: The material lets moisture vapor out, reducing heat build-up compared to ordinary polypropylene coveralls.
Durable: It resists wear and tear well, keeping its protection intact during use.
Lightweight: Weighing between 47 and 92 grams per square meter, most disposable coveralls are around 50–65 gsm for good comfort.
Why Microporous Is Better Than Standard Polypropylene
Regular polypropylene coveralls do not have breathable films. This traps sweat and heat, causing discomfort. Microporous coveralls have a high Moisture Vapor Transmission Rate (MVTR), helping heat and sweat escape. This makes them more comfortable, especially in hot or active work conditions.
Common Uses of Microporous Coveralls
- Painting and renovation: Protects against paint splashes and dust.
- Food processing: Blocks tiny food particles and liquids, and is gentle on the skin.
- Cleaning: Shields from light chemical splashes and dust.
- Laboratories and healthcare: Stops exposure to biological fluids and contaminants.
Additional features found in many products include anti-static treatment (to reduce dust attraction), reinforced areas for durability, and elastic closures for a better fit. Some are designed to be disposable and eco-friendly, with soft fabric inside for comfort during long work shifts.
Microporous coveralls provide a balanced solution with strong protection, breathability, and comfort across many industries.
Key Features to Look For in Microporous Coveralls
Microporous coveralls use special fabrics with tiny pores that block liquids and particles but let moisture escape. This design keeps you comfortable while providing protection. High-quality microporous films stand out with strong splash resistance and durability. They can protect well against tough chemicals like sulfuric acid and sodium hydroxide.
Types of Fabrics and Protection Levels
Flashspun polyethylene and microporous film laminates are common materials.
Microporous film laminates usually offer higher protection, such as Class 6 for liquid repellency and penetration.
Quality varies between disposable coverall manufacturers, so it’s important to choose reliable coverall brands.
Seam Construction: Serged vs. Taped Seams
Serged seams are sewn with thread and give basic strength, but may allow liquids to pass through tiny stitch holes.
Taped seams have a waterproof tape covering the stitches, greatly improving liquid resistance.
Taped seams are essential for high-risk environments and are required for Type 4 coveralls with heavy splash exposure.
Fit and Additional Protective Features
A proper fit covers the body fully and reduces gaps where contaminants could enter.
Elastic wrists and ankles help create a secure seal.
Hoods protect the head and neck, important for high-risk exposure.
Some coveralls include attached boot covers made from materials like PVC or polyethylene to protect feet and stop contamination.
Certification and Task Suitability
Type 5 coveralls protect against airborne particles (EN 13982-1 tested).
Type 6 coveralls protect against limited liquid splashes (EN 13034 tested).
Many models also have EN 14126 certification for infectious agent protection.
Choose coveralls based on task duration and risk:
- For short, low-risk tasks, lighter coveralls with serged seams may be enough.
- For longer, higher-risk jobs, use heavy-duty coveralls with taped seams, hoods, and boot covers.
Always check for damage before use and follow proper disposal rules after exposure.
