Comparing Coveralls: Microporous, Tyvek, SMS, and Polypropylene - A Comprehensive Guide

When it comes to selecting the right coveralls for your workplace, it is essential to consider the various materials available and their specific benefits. In this article, we will discuss the differences between microporous, Tyvek, SMS, and polypropylene coveralls to help you make an informed decision.


Material Applications
Microporous Chemical handling, pharmaceutical, asbestos removal, paint spraying, contamination control, cleanroom environments, automotive refinishing, fiberglass handling, and general maintenance
Tyvek Asbestos abatement, lead remediation, general maintenance, spray painting, cleanroom environments, chemical processing, pharmaceutical, food processing, and agricultural industries
SMS Medical facilities, laboratories, pharmaceutical, light chemical handling, automotive, food processing, and general maintenance tasks
Polypropylene Non-hazardous environments, general maintenance, light clean-up tasks, food processing, and medical facilities


Microporous Coveralls

Microporous coveralls are made from a film-coated, non-woven fabric that provides a barrier against liquid and particulate contaminants. These coveralls offer excellent breathability, making them suitable for extended periods of wear. Industries that commonly use microporous coveralls include asbestos removal, painting, and pharmaceuticals.

Tyvek Coveralls

Tyvek suits, produced by DuPont, are made from high-density polyethylene fibers, creating a lightweight, durable, and comfortable material. Tyvek offers a superior barrier against particles as small as 1.0 micron and provides resistance to wear and abrasion. Tyvek coveralls are commonly used in lead and asbestos abatement, general maintenance, and spray painting applications.

SMS (Spunbond Meltblown Spunbond) Coveralls

SMS coveralls combine spunbond and meltblown polypropylene layers, resulting in a fabric with excellent liquid and particulate barrier properties while remaining breathable. These coveralls are ideal for pharmaceutical, food processing, and cleanroom applications due to their balance of protection and comfort.

Polypropylene Coveralls

Polypropylene coveralls are made from lightweight, spunbond polypropylene fabric, offering basic protection against dirt, dust, and light liquid splashes. They are best suited for applications requiring low-level protection and comfort, such as general maintenance, food processing, and cleaning tasks.

Price Comparison

When comparing the prices of these different types of coveralls, microporous and polypropylene coveralls are typically the most cost-effective options. Tyvek coveralls tend to be more expensive due to their specialized material and higher level of protection. SMS coveralls are priced between microporous and Tyvek coveralls, offering a balance of protection, comfort, and affordability.


Selecting the appropriate coveralls for your workplace depends on the specific hazards and requirements of your industry. By understanding the differences between microporous, Tyvek, SMS, and polypropylene coveralls, you can make an informed decision that best meets your needs in terms of protection, comfort, and cost.
