Everything You Need to Know About WZ Series XLPE Foams
The WZ line was created to give fabricators a premium XLPE option without the headaches of long lead times, tariffs, or limited color choices. Made in the USA and engineered with Zotefoams’ unique nitrogen expansion process, WZ foams offer uniform density, low VOC emissions, and excellent yield thanks to our exclusive 48″ × 80″ sheet size. As a result, fabricators can achieve consistent performance while maintaining production efficiency and material reliability.
Introducing WZ-20: Designed for Packaging with Performance and Value
As the newest addition to the WZ family, WZ-20 joins the WZ family as the go-to solution for cost-sensitive packaging projects that still demand the polish and reliability of nitrogen-blown XLPE foam. With 1.5 lb/ft³ density, WZ-20 cushions better, absorbs impact effectively, and offers a smoother surface compared to standard PE foam, all while providing a cost-effective alternative for demanding applications.
Additionally, WZ-20 was designed to balance performance and value. While its softer structure and larger cell size mean WZ-20 isn’t ideal for precision CNC routing like WZ-30 or WZ-40, it excels in shock absorption and works perfectly for protective packaging, medical device shipping, and defense applications. Because of this, WZ-20 is an excellent choice for applications where cushioning and impact protection are critical.
WZ Series FAQs
To help you compare available options and determine the best material for your application, we’ve rounded up answers to the most common questions about WZ foams:
Q: What makes the WZ Series different from commodity XLPE?A: WZ foam uses Zotefoams’ unique nitrogen expansion process, resulting in low VOC, even cell structure, and consistent quality without chemical blowing agents. This process helps provide reliable performance and a cleaner material option compared to traditional foam manufacturing methods. |
Q: What size and colors are available?A: All WZ foams are supplied in fabricator-friendly sheets of 2″ x 48″ × 80″ (WZ-40 slightly thinner at 1.375″ thick). Available options include:
|
Q: What is WZ-20 designed for?A: WZ-20 was formulated as an economical option for protective and luxury packaging. Specifically, it performs well in applications where cushioning and shock absorption are priorities. |
Q: How does WZ-20 compare to WZ-30 and WZ-40 in CNC routing?A: It doesn’t route as precisely. Due to a lower density (1.5 lb/ft³), a softer feel, and larger cell structure, it won’t hold tight tolerances like WZ-30 (1.9 lb/ft³) or WZ-40 (2.5 lb/ft³). Therefore, WZ-30 and WZ-40 are better choices for clean, detailed CNC cuts and tool control boards. |
Q: Why choose WZ-20?A: WZ-20 provides excellent cushioning performance. Because of its softer structure, it absorbs impact more effectively than higher-density foams, making it excellent for shipping protection and drop-sensitive products. |
Q: Is it a substitute for commodity PE foam?A: Yes, with added benefits. Compared to traditional PE foam, WZ-20 offers a smoother, higher-quality surface finish while keeping the cost closer to traditional PE foam, giving you an upgrade without breaking your budget. |
Q: What are the key features of WZ-20?A: Density: 1.5 lb/ft³; Sheet size: 2″ × 48″ × 80″; Colors: Black, Natural, and Grey; Made in USA / Berry Amendment Compliant; Nitrogen-blown and low VOC emissions; Consistent and clean cell structure. |
Q: Where should I use WZ-20?A: Medical device packaging, government/military kits, electronics protection, or luxury goods shipping cases. Whether the priority is impact protection, presentation, or reliable cushioning, WZ-20 provides a versatile solution for a variety of applications. |
