ABOVE GROUND SWIMMING POOL C O M P O S I T E S I D E W A L L • Corrosion resistance to withstand salt water pool treatment • UV resistance for durability over years of use • Weight reduction vs. traditional metal to reduce shipping costs and simplify installation • Field tested for 3 years to prove Polystrand solution provides excellent UV, creep, and corrosion resistance • Reduced weight by 50% compared to metal • Rolled product enabled standard shipping vs. coiled steel sidewalls that require LTL delivery Polystrand™ thermoplastic composite laminate (4-ply) with integrated decorative film KEY REQUIREMENTS WHY AVIENT?

Typical let-down ratios for Hydrocerol concentrates are 1–3%. INJECTION PRESSURE The injection pressure must be set high enough to obtain a high injection rate (Figure 3). Typically, a weight reduction of 10–25% is achieved in parts with wall thicknesses >4 mm and short flow paths.
