Skyi Composites
Strength. Stability. Sustainability.

Skyi pioneers sustainable polymer materials with cutting-edge science and over three decades of expertise. Our deep understanding of fiber-matrix chemistry, morphology, and rheology drives innovation, setting new benchmarks in performance, durability, lightweighting, and recyclability.
Matrix Polymer Composition and Structure
Our LFTs typically use recyclable thermoplastics such as polypropylene (PP), polyamide (PA), Polyethylene Terephthalate (PET), Polybutylene Terephthalate (PBT), etc. The choice of polymer impacts mechanical strength, thermal stability, and chemical resistance.
Fiber–Matrix Reinforcing Chemistry
We focus on strengthening the bond between reinforcing fibers, such as glass or carbon, and the polymer matrix to create durable, high-performance composites. Strong adhesion at this interface is essential for efficient load transfer.
Crystallinity and Morphology
In LFTs Degree of crystallinity, size, distribution, and orientation of crystalline regions influence overall mechanical performance and thermal behavior. Our patented technology redefines performance with superior bonding and crystallinity, surpassing conventional wire coatings and pre-impregnated long glass fibers.
Melt Rheology and Processing Behavior
We optimize the polymer’s melt flow characteristics for efficient injection molding while minimizing breakage. After processing, the 10-12mm fibers in our LFT retain a robust length, enhancing the composite’s strength and durability.
Performance Modifiers
Our Long Fiber Thermoplastics (LFTs) are built for durability, with stabilizers and impact modifiers that protect against UV exposure, oxidation, and stress. Processing aids enhance melt viscosity and crystallization, ensuring smooth, efficient production.
Engineered Endurance
LFTs offer exceptional thermal stability, maintaining strength across a wide temperature range. Defined by glass transition and melting temperature, they resist thermal degradation, ensuring reliable properties in high-heat environments.
Weatherproof Composition
Built for demanding conditions, LFTs offer superior resistance to chemicals, moisture, and UV, ensuring long-term reliability. Advanced aging resistance protects against temperature changes, and environmental degradation, maintaining strength over time.
