The LFT Advantage: Why Long Fiber is Essential at 60% Loading

At an extreme 60% glass fiber loading, the distinction between long fiber (LGF) and short fiber (SGF) technology becomes more critical than ever. An SGF composite at this level would be exceptionally brittle and difficult to process. Our LFT-G^® technology is what makes a 60% reinforced polypropylene a viable, high-performance engineering solution. Long Fiber vs Short Fiber Structure

The technology preserves fiber length, creating a dense, continuous **internal glass fiber skeleton**. This robust, interwoven network is the key that unlocks peak performance:

Structural Cohesion and Toughness: The long fibers effectively bridge the polymer matrix, preventing catastrophic failure under stress and retaining a level of toughness that is impossible to achieve with disjointed short fibers.
Maximum Stress Transfer: The continuous fiber network provides an uninterrupted path to transfer load throughout the component, ensuring that the full strength potential of the 60% glass reinforcement is realized and delivering exceptional performance under sustained load (creep).
