Our comprehensive portfolio consists of Polystrand™ and Fiber-Line™ branded tapes, made using unique processes and materials to customize performance properties to meet specific application requirements such as tensile and flexural strength, impact performance, creep, chemical, and UV resistance.

Avient uses a “systems approach” to develop the laser welding solution most adapted to your project, taking into consideration the following aspects: • Transmitting and absorbing parts • Polymer type and grade • Dispersion of the additive in the final part • Sufficient and consistent loading of the additive • Part design: attention to flow separation at the welding interface • Color and opacitiy • Quality control – e.g. establish suitable control parameters (UV Visible Spectra) • Laser wavelength and processing parameter Mevopur™ Healthcare Functional Additives formulated for laser welding are designed for use in healthcare applications.

Performance advantages: • Non-conductive: formulations engineered to optimize composite dielectric properties • Lightweight: up to 80% lighter than porcelain, reducing installation time and cost • High strength: high tensile, compressive, flexural and inter-laminar shear strength to support various design configurations and line loads • Flexible: deflect and return to original shape for load dampening to minimize damages and outages • Durable and shatter resistant vs. ceramic and glass, and UV and corrosion resistant for long service life INSULATORS AND ARRESTERS OVERHEAD SWITCH RODS CROSSARMS AND BRACES COMPOSITE POLES GUY INSULATORS Electrical Transmission & Distribution Applications COMPONENT DESCRIPTION SIZES Insulators for transmission and distribution Suspension insulators Epoxy/corrosion resistant glass rods .625" to 1.25" diameter Line post and station post insulators Epoxy/glass fiber rods 1.50" to 4.74" diameter Arresters Cage type Polyester or vinyl ester/glass fiber rods .125" to .50" diameter Custom tubular Polyester, vinyl ester or epoxy/ glass fiber custom shapes 2.0" to 6.0" envelope size Pole line construction Conductor standoff and equipment support arms Polyester/glass fiber rods 1.50" to 2.00" diameter Guy strain insulators Polyester/glass fiber rods 0.50" to .812" diameter Cross arms Tangent and deadend, support braces Polyester/glass fiber rectangular tubes 3.62" x 4.62" and 4.0" x 6.0" rectangular Utility poles Composite poles Polyester/glass fiber hollow custom tubes 10" to 14" diameter, typical lengths 40' to 110' Pole line construction, cross arms, rods, and utility poles feature an integral fabric surfacing veil for long-term weather resistance and retention of properties.
