Deliver game-changing performance and affordability to a variety of products.

Eklipse® materials are fiber reinforced composites. Fibers such as glass, wood, carbon and aramid are coated with Tundra’s proprietary technology (TundraKoat™) and compounded into thermoplastics at varied loadings to meet specific physical properties. Eklipse® materials can be used in the automotive, aerospace, building & construction, electrical & electronics, energy, and consumer goods markets. Eklipse® materials can be engineered for specific thermal, mechanical, and rheological properties.

How Eklipse® Came to be:

With our experience in loading particles such as stainless steel and strontium ferrite, aided by TundraKoat™, we saw an opportunity to load fibers into polymers without the drawbacks seen by competitors.
  • In extrusion, we found that we are able to load these fibers with little to no increased wear on equipment when compared to traditional polymer extrusion.
  • In injection molding, we are able to lower the viscosity of products at all loadings allowing for easier processing as well as ability to increase loading.

The Scope of Eklipse® Today:

  • Glass Fiber
  • Wood Fiber
  • Wollastonite Fiber
  • Polyvinyl Chloride (PVC)
  • Polypropylene (PP)

The Future of the Eklipse® Platform

While most of Tundra’s focus has been PVC to date due to previous experience in the building and construction industry, we have begun work on polypropylene commercialization. We will continue target fiber/polymer combinations based on market need.

Future Eklipse® Fibers/Polymers:
  • Carbon Fiber
  • Aramid Fiber
  • Basalt Fiber
  • Polyethylene (PE)
  • Nylon (PA)
  • Polyester
  • ABS
  • PET
  • PEEK
  • PEKK
  • PAEK
  • PPS

Platform Benefits

In Extrusion

Increased processability and loading enhances the following properties:
  • Increased Strength
  • Specifically flexural modulus
  • Allows for use of dark colors and large sizes
  • Increased Heat Distortion Temperature (HDT)
  • Decreased Coefficient of Thermal Expansion (CoTE)
  • Value Comparable to Market Products
  • Easy to Use
    • Your Polymer + Our Masterbatch
    • Ready to use pellets

Processed with traditional plastics processing equipment without the fear of increased wear which has typically been a limiting factor with fiber filled materials.

In Injection Molding

Increased mechanical strength, rigidity, hardness, and thermal stability as well as resistance to chemicals, abrasion, and impact

How Eklipse® can benefit you

Tundra provides additive materials that enhance your existing or new products to exceed market demands. Benefits Include:
  • Market share expansion through increased product performance
  • Product systems cost reductions
  • Increase in annual revenue and profitability
  • Reduced product complaints and increased performance
  • Additive systems require little or no additional capital investment in processing equipment

The Masterbatch Advantage

Your Polymer + Our Masterbatch

With the benefits of higher loading while retaining processability, Tundra is able to offer a fiber masterbatch which can then be let down by our customer. This masterbatch process allows our customers to retain their polymer supply as well as additive packages formulated for their product. It also allows our customers the ability to fine tune the fiber concentration in their end product.

The graphic below explains how the masterbatch process works in your process. A major benefit of the method is that it allows customers who to source/use their own PVC supply as well as being able to dial in the exact percent on glass fiber that works for their applications.

Applications for Eklipse® Materials

Tundra can assist you at any stage of materials innovation — from idea and development through technology transfer and production.
