Transforming Applications and Markets with Long Fiber Reinforced Thermoplastic Technology

Thermoplastic compounder focused on long fiber materials
Over 700 years of composites industry expertise
Headquartered in Winona, Minnesota, U.S.A.

PlastiComp was founded in 2003 by veterans of the thermoplastic composites industry who knew how to incorporate the stronger, tougher, and lighter benefits of long fiber reinforcement technology into new applications and markets to create better products.

Using a collaborative philosophy combined with a fully integrated approach to application development, we focus our expertise on developing and delivering innovative, made-to-order long fiber reinforced thermoplastic composite solutions to satisfy application specific requirements for structural performance.

In 2018 we became a part of PolyOne Corporation — a premier global provider of specialized polymer materials, services and solutions — to expand the reach for our unique materials and business methodology. In 2020 PolyOne Corporation became Avient Corporation, which we are a proud component of today.

Transformative Solutions

We manufacture long fiber composite pellets using a proprietary pultrusion process that melt impregnates continuous carbon, glass or other specialty fibers with thermoplastic polymer matrices ranging from polypropylene to PEEK to achieve high performance. Our composite pellet products are formed into finished articles by processors using injection molding.

For those unfamiliar with using fiber-reinforced composites to replace metals or under-performing materials, PlastiComp has capabilities to assist you from product concept through production. We provide single-vendor or à la carte options for product design, performance analysis, composite selection, composite pellet production, and processing into finished components.

Integrating Technology

Adapting long fiber technology to new applications and markets, especially when high performance engineering polymers or long carbon fiber reinforcement is required, is our forte. It’s all about those filaments of fiber and properly deploying them to meet your structural performance requirements.

Our integrated approach overcomes metal-to-plastic conversion challenges by taking product design, material performance, and processing method into consideration to develop a custom solution that delivers a better final product.

Agility is one of our defining cultural characteristics; our team is used to working on fast-paced timelines while always remaining committed to obtaining our success by ensuring our partners succeed.

Sharing Our Expertise

With a significant amount of composites experience and knowledge, PlastiComp’s team of design, material and process engineers are always accessible to answer your questions as a partner to support you throughout your entire product life cycle.

We continually engage in new product and process research to expand the performance envelope and use of long fiber technology in new and innovative ways.

Performance Fits

The high strength-to-weight-ratio of long fiber reinforced composites makes them an ideal substitute for metals or under-performing materials. They are widely used to produce lightweight and cost-effective structural components for aerospace, appliance, automotive, construction, defense, electronics, fluid handling, healthcare, industrial equipment, robotics, sporting goods, transportation, and other markets that require high performance materials.

Built For Success

PlastiComp operates two facilities in Winona, Minnesota, totaling 140,000 sq. ft. (13,000 m²) that comprise our corporate offices, technical development center, composite pellet manufacturing, and captive processing operations. We are guided by an ISO 9001:2015 certified quality system.
