Media for Photovoltaic

This media is used in both flexible and rigid PV panels. The benefits of our Craneglas® products were initially discovered by NASA in the early 1980’s. The Craneglas® 230 grade- sub weights 4.8, 6.1, and 11.0 have all been used at either the film manufacturer level or the panel manufacturers themselves. The substrate provides many benefits during the encapsulation and laminating processes; creating channels for air flow eliminating bubbles, stabilizing the EVA film to minimize shrinkage and overflow, providing structural stability for thin film flexible modules and prevents shorts caused by cell movement.

Media for environmental control

Our Craneglas® media is used as a substrate in both desiccant wheel dehumidification and evaporative cooling for commercial buildings and industrial settings. Neenah’s material is easily corrugated and adaptable to accommodate different corrugating techniques, has high resin pick-up and absorbency while maintaining sufficient wet strength during fabrication.

Media for thermal, electrical & acoustical insulation

The advantages of our Craneglas® media is based on the wet-laid process which ensures dimensional stability, consistent weight, thickness, and density. It is thermally stable up to 1200°F and has a low thermal conductivity per (ASTM C518) with a UL 94 V-0 flammability rating. It is resistant to alkaline and acidic environments. Of course, these materials can be combined with our specialty coatings for further specialization per customer request; making it optimal for thermal, electrical, & acoustical insulation applications such as:

  • Appliance gaskets
  • Heat Trace Wrap
  • Electrical wire/cable wrap
  • Office Partitions
  • Facing (liner)

Aerospace composites

This media was developed to have high temperature resistance with a thermoplastic base, making it easy to mold. It has superior flame, smoke (ASTM E662) & toxicity (BSS 7239) ratings and are very lightweight.

Surface Veils

One of the initial uses for our Craneglas® 230 grades were in surface veils for various composite applications, from surf boards to cafeteria serving trays. The randomly dispersed fibers of Neenah’s wetlaid nonwoven produce a hydrophilic sheet with even wet-out, that is compatible with most resin systems. It can be easily printed on and its uniformity creates a functional aesthetic; which helps smooth out surfaces while adding durability, insulating characteristics, and corrosive resistance for many different composite applications including Fiberglass Reinforced Plastic (FRP) products.    

Battery Separator

Our Craneglas® 230 product line is made with short-cut/coarse E-glass fibers, which provide uniform fiber distribution and pore sizes perfectly suited for separators in both cylindrical and bobbin style primary batteries that use the Lithium-Thionyl Chloride chemistry for high-energy and high-voltage requirements in extreme temperatures.
