These methods include: PULTRUSION • Fibers are impregnated with liquid thermoset resins, then pulled through a heated die to cure the resin and form the product • This continuous, automated manufacturing process creates constant cross section profiles of any pre-determined length with consistent, uniform quality and exceptional mechanical performance • Applications include rods and profiles of various lengths and complexities, such as utility poles, insulator core rods and structural beams CONTINUOUS FILAMENT WINDING • Combines the principles of filament winding with pultrusion to create constant or tapered cross- sectional tubing in precision sizes • The unique axial and biaxial fiber orientation provides flexural and tensile strength, as well as crush and burst resistance • Applications include lightweight shelter frames and sporting goods components CONTINUOUS RESIN TRANSFER MOLDING (CRTM™) • Engineered core materials are sandwiched between structural composite laminate face sheets • Continuous composite sandwich panels feature high specific strength and stiffness-to-weight ratio • Applications include ballistic resistant panels, truck floors and rail car doors CONTINUOUS FIBER REINFORCED THERMOPLASTICS • Fully recyclable tape, X-Ply™ (0°/90°), and other multi-ply configurations with widths up to 10' wide • Sandwich panels in unlimited lengths, up to 6" thick and 10' wide • High volume production capacity • Applications include structural and aerodynamic components in transportation, and reinforcement of materials such as wood and metal THERMOSET COMPOSITE LAMINATES & BARSTOCK • Unidirectionally reinforced barstock, laminates and hybrid composites engineered to maximize deflection and fatigue resistance • Customizable shapes and sizes • Applications include archery bow limbs, flat springs, prosthetics, sporting equipment THERMOSET FINISHING OPERATIONS • Customized finishing capabilities for barstock and laminates including machining, water-jet cutting, profiling/shaping, sanding, slitting, laminating, molding and coatings TESTING CAPABILITIES • Mechanical – Flexural, tensile, compression, shear, fatigue, impact resistance • Physical – Specific gravity/density, Barcol hardness, water absorption, void content, resin/fiber content, dye penetrant, viscosity • Thermomechanical – Coefficient of linear thermal expansion, glass transition temperature, deflection temperature, degree of cure, curing properties • Electrical – High-voltage, low current dry arc resistance of solid electrical insulation, dielectric strength, water diffusion ABOUT AVIENT ADVANCED COMPOSITES The Avient advanced composites portfolio consists of Glasforms™, Gordon Composites™ and Polystrand™ branded materials.

When closurelogic turned to Avient for material selection help, the team developed a GLS™ TPE (thermoplastic elastomer) based on a stable, low migration TPE with a lower processing temperature compared to competitive TPEs, thus resulting in even fewer volatiles. Lined with TPE, closurelogic caps have outstanding tightness for sealability of both one-way and refillable bottles, while maintaining good removal torque. Avient offers GLS TPE cap liner formulations that are suitable for aqueous, acidic and low alcohol beverages processed under ambient, pasteurized or hot fill conditions.

Glasforms™ Pultruded Rods, Tubes & Custom Profiles

Versaflex™ TPE materials offer great compression set properties for gaskets that need a long lasting seal, and also create durable speaker skins with a silky feel. These TPEs meet industry ingress protection (IP) standards, are overmoldable directly onto common speaker housing substrates, and deliver more design freedom than you’ve ever thought possible. Versaflex TPEs safely deliver on all of these requirements, while also accelerating production speed and reducing manufacturing cost.
