A sustainable thermoplastic composite

THRIVE: A Revolution for Your Plastic Products

THRIVE composites use cellulose fibers to reinforce various plastics, allowing customers to bypass many of the current challenges with conventional fiber-reinforced composites like fiberglass. In fact, in real-world manufacturing, THRIVE behaves like no other material, offering:

  • Improved part quality
  • Enhanced molding efficiency
  • Higher productivity
  • Reduced energy needs
  • Cost savings
  • Many other benefits




Warm to Touch

Low Odor

Highly Colorable

Bonds Easily

Strong at Low Weights

From Trees to THRIVE—The Difference Inside

Trees are life, and THRIVE composites represent that life. THRIVE begins life as a pine seedling that grows rapidly.

After the bark is removed and the tree cut into planks for houses and other useful products, the wood chips are processed to remove sugars and glues, leaving highly purified cellulose fibers.

These refined cellulose fibers can be blended with a variety of plastics to create the strong, lightweight, environmentally responsible material that is THRIVE composites. And because the cellulose fibers are highly purified, there’s very little darkening or odor when correctly compounded into selected thermoplastic resins.

Possibilities for THRIVE—Diverse as Your Imagination

THRIVE composites improve performance in applications requiring fiber-reinforced and fiber-filled thermoplastics, as well as filled and unfilled styrenic and olefinic polymers, including:

  • Automotive parts
  • Office furniture
  • Household goods and kitchenware
  • Small and large appliances
  • Wheels and pulleys
  • Consumer personal goods
  • Building and construction goods

Easy to Use, More Productive—Plus Environmentally Responsible

THRIVE composites can be easily injection molded, and parts made with THRIVE are:

More productive and economical
THRIVE melts and is highly moldable at significantly lower melt temperatures than other composites, requiring less energy to produce and much faster cooling times. These features significantly reduce overall part costs while significantly improving manufacturing productivity.

Lighter weight
The cellulose fibers in THRIVE have a lower specific gravity than other common reinforcement materials yet provide the strength and resilience found in trees. Some manufacturers have reduced part weight by as much as 15 percent versus previous composite options

Design friendly
THRIVE gives you more options than ever before, including: 

  • Stronger knit lines and improved over-molded bond strength with TPEs, Complete or partial fiber dispersion, 
  • No surface sink in parts with many ribs and bosses, and
  • A range of color choices and recycled plastic options.

Environmentally responsible
THRIVE is a tree-based bio-composite that can improve your environmental footprint by replacing less sustainable alternatives (such as glass fibers), reducing energy consumption, and lowering the final weight of your finished components. What’s more, we offer new grades using recycled base polymers, and THRIVE itself can be reground and used again and again without a significant loss of mechanical properties due to the unique three-dimensional structure of International Paper’s fiber molecules.
