These tapes and laminates combined high strength, unidirectional fibers and engineered thermoplastic resins to help reduce weight while maintaining exceptional strength and impact resistance.

Compared to traditional pole materials, fiber reinforced polymer (FRP) composites are more durable, require less maintenance, and provide a longer service life. The poles have an excellent dielectric strength that allows for safer installation near energized lines. FRP data are from tests--nominal fiber stress is at 5% LEL; modulus of elasticity is at mean.

With a new digital home and refreshed look and feel, the world’s strongest fiber™ builds on its exceptional heritage while leading innovation for the future Formed from two Greek words meaning “strong” and “fiber,” the name Dyneema® has become a byword for strength in applications and industries worldwide. Sustainable infrastructure solutions that increase energy efficiency, renewable energy, natural resource conservation, and fiber optic / 5G network accessibility      

Continuous Fiber Reinforced Thermoplastics    Long Fiber Thermoplastics (LFTs)   LFTs are fiber reinforced thermoplastic pellets used in injection molding machines.

SHANGHAI – PolyOne Corporation (NYSE: POL), a premier global provider of specialized polymer materials, services and solutions, has announced the launch of OnCap™ UV technology for fiber and textile applications. Manufacturers of geotextiles and house wraps require fabrics and fibers to stand up to the sun without falling apart. Those who make UV resistant apparel, outdoor tents and shades also need the colors in their fabrics and fibers to stay fresh over time to promote brand identification and preserve brand image.  

Polystrand™ Continuous Fiber Tapes & Laminates Polystrand™ Continuous Fiber Reinforced Thermoplastic Composites provide a reinforcing layer within the high density polyethylene (HDPE) pipe wall through thermal wrapping that is integrated into the pipe manufacturing processes. Video Polystrand Unidirectional Composite Tape Continuous fiber reinforced thermoplastic composite tape is slit to custom widths from 2" to 24".
