For this manufacturer, another appealing aspect of working with this material was Avient’s dedicated TPE production line in Spain, which is used solely to manufacture TPEs for overmolding applications. The material helps the company produce attractive, high-quality garden sprayers featuring precisely fitting parts. Customers can keep a firm grasp of the sprayer to prevent dropping or twisting. • Abrasion resistance = excellent appearance to uphold corporate image: The Avient material resists scratching and scraping that commonly occur when sprayers are dragged along the ground or left out in all types of weather.

It has no negative effect on recyclability, physical performance characteristics or color of the recycled material. In some situations the Ultimate UV range can vastly improve both the processing and mechanical properties of packaging incorporating recycled material. Processing conditions can cause material properties to shift from the values stated in the information.

GLASFORMS™ ELECTRICAL COMPONENTS Composite Materials for Power Transmission and Distribution Products APPLICATION & PRODUCT SELECTION GUIDE Insulators Overhead Switch Rods Cross Arms GridCore™ Composite Pole Guy Insulators KEY CHARACTERISTICS Extend the service life of electrical transmission and distribution products with Glasforms™ composite technologies. Performance advantages: • High dielectric strength: composite material is custom formulated to optimize electrical properties resulting in exceptional insulation • Lightweight: insulators are up to 80% lighter than porcelain and utility poles are more than 50% lighter than wood equivalents • High strength: high tensile, compressive, flexural and inter-laminar shear strength to support various design configurations and line loads • Resilient: deflect and return to original shape for structural damping to minimize damages and outages • Durable: insulators are durable and shatter resistant vs. ceramic and glass; composite utility poles are UV corrosion resistant for a long service life Arrestors Electrical Transmission & Distribution Applications COMPONENT DESCRIPTION SIZES Insulators for transmission and distribution Suspension insulators Epoxy/glass fiber rods 0.625" 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 0.125" to 0.50" 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 0.812" 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 GridCore™ Composite Utility Poles Polyester/glass fiber hollow custom tubes 12" to 14" diameter, typical lengths from 35' to 75' Pole line construction, cross arms, rods, and utility poles feature an integral fabric surfacing veil for long-term weather resistance and retention of properties. Processing conditions can cause material properties to shift from the values stated in the information.

Couple this with the residual heat in the material and a situation is created that mimics a transfer press. Processing conditions can cause material properties to shift from the values stated in the information. Processing conditions can cause material properties to shift from the values stated in the information.

They are based on management’s expectations that involve a number of business risks and uncertainties, any of which could cause actual results to differ materially from those expressed in or implied by the forward-looking statements. Pro Forma Financial Information The Company acquired Avient Protective Materials (“Dyneema”) on September 1, 2022 (the “Acquisition Date”) and sold the Distribution segment on November 1, 2022. To provide comparable results, the company references “pro forma” financial metrics, which include the business results of Avient Protective Materials for periods prior to the Acquisition Date, as if the transaction occurred on January 1, 2021 and reflect Distribution as a discontinued operation.

Seeking to create a more innovative and comfortable insole using state-of-the-art materials, Gordon and his partner, Jeff Milliman of Greenville Running Company, went to work. The fiberglass material, which is less stiff than carbon, proved to provide greater comfort and gave the energy return they were looking for. THE SOLUTION After extensive research, Gordon found the material that met his requirements: Avient’s Polystrand™ unidirectional thermoplastic tape.
