When it comes to engineered plastic sheeting and geomembrane liners, selecting the right material for your project can make all the difference. Two products often compared are Permalon® Ply X-200 FR and Permalon® L30 Black, both manufactured by Reef Industries. While they are both designed for durability and strength, they serve distinct purposes. Understanding their differences will help you make the right choice for your application.
Permalon® Ply X-200 FR is a fire-retardant, cross-laminated polyethylene film designed for a variety of construction and industrial uses. It is composed of multi-axially oriented linear low-density polyethylene (LLDPE), which gives it high strength and tear resistance while keeping it lightweight.
Fire Retardant: Meets NFPA 701 Test 2 (Large Scale), making it suitable where flame resistance is required.
Durability: Designed for rugged environments while maintaining flexibility.
Typical Applications:
Architectural vapor retarders
Underslab and wall barriers
Temporary walls and dust partitions
Cleanroom enclosures
Containment tents
Permalon® Ply X-200 FR is ideal for situations where both strength and flame resistance are critical. This makes it a great choice for construction sites, industrial environments, and temporary structures.
Permalon® L30 Black, on the other hand, is a 30 mil thick high-strength geomembrane liner. Though it does not offer fire-retardant properties, it is specifically engineered to perform in demanding liner applications.
High Strength: Made for durability and longevity in outdoor and rugged environments.
Non-Fire Retardant: Focused on strength and flexibility over flame resistance.
Typical Applications:
Pond liners
Containment barriers
Vapor barriers
Permalon® L30 Black is particularly well-suited for lining projects that require a heavy-duty solution. It is popular in aquaculture, agriculture, construction, and environmental containment applications.
| Feature | Permalon® Ply X-200 FR | Permalon® L30 Black |
|---|---|---|
| Fire Retardant | Yes (NFPA 701) | No |
| Thickness | Lightweight (cross-laminated) | 30 mil thick |
| Typical Use | Temporary barriers, cleanrooms, vapor retarders | Liners for ponds, barriers, and containment |
| Durability | High strength and flexible | Extremely durable and strong |
Choosing between Permalon® Ply X-200 FR and Permalon® L30 Black depends entirely on your project needs.
Choose Permalon® Ply X-200 FR if:
Your application requires flame resistance.
You need a lightweight yet durable material.
You’re building enclosures, containment tents, or vapor barriers indoors or in public spaces.
Choose Permalon® L30 Black if:
You need a tough, thick liner for ponds, agriculture, or environmental containment.
Flame retardancy is not a requirement.
Long-term durability in rugged outdoor conditions is essential.
While Permalon® Ply X-200 FR and Permalon® L30 Black both offer outstanding performance, they are designed for different types of applications. Ply X-200 FR excels in flame-retardant and temporary barrier applications, while L30 Black is the go-to option for heavy-duty lining projects. By understanding these key differences, you can confidently select the right geomembrane liner to ensure the success and safety of your project.
