Compel® LFT

Processing
Compel LFT is suitable for plasticizing/compression molding. In processing all Compel LFT grades should be taken to ensure that fiber breakage is kept to a minimum. The longer the glass fibers in the component, the better are its mechanical properties.

Structure
Compel LFT is the trade name for long fiber reinforced thermoplastics for plasticising/compression molding in composite engineering. Compel LFT has a standard length of 25 mm, the fiber length being identical to the pellet length.

Like Celstran LFT, Compel LFT is produced by a pultrusion process.

Properties
The Compel LFT property profile is comparable to that of Celstran LFT. Due to the greater fiber length and the gentle fiber treatment in the plastifying process, however, much higher impact resistance and energy absorption are attained, especially in the case of large-surface structure components.

Grades
The most requested Compel LFT grades are long glass fiber reinforced polypropylenes. Other matrix materials, such as polyamides, or other fiber materials, such as carbon fibers, are also possible.

Compel LFT materials can be adjusted to varying application requirements. They are available as high solidity products or with increased impact-resistance. All Compel LFT versions are heat stabilised. When glass is used as reinforcement fiber, its content varies between 30 and 55%. The glass fibers are chemically bonded.

Applications
Compel LFT is mainly applied in the automobile industry for large surface structure components such as front ends, underbody modules and control panel bases. When added as a concentrate to recycled polymer materials, significant property improvements can be attained as is the case with Celstran LFT.
