When you’re thermoforming parts for aerospace interiors, medical equipment, or electronic housings, material choice can make or break your budget and schedule. KYDEX® T has long been a go-to for its strength and fire performance, but it comes with drawbacks—longer lead times, higher minimum orders, and higher costs.
Enter Boltaron® 4335—a high-impact, flame-rated thermoplastic sheet that matches KYDEX T’s performance in critical areas, while offering a smoother path to production.
Why More Manufacturers Are Switching to Boltaron® 4335
Boltaron 4335 is a rigid PVC-based material with serious mechanical and thermal stability. With a tensile strength of 6,000 psi and flexural strength of 9,200 psi, it holds its shape under stress. Its impact resistance is even more impressive—18 ft-lb/in—making it ideal for tough, high-traffic environments.
It also earns top marks for flammability compliance: UL 94 V-0, 5VA, and FAR 25.853(a) for vertical burn. It’s safe for use in aircraft cabins, public kiosks, and hospital-grade applications.
From a process standpoint, Boltaron 4335 shines. It forms easily at 335–370°F and doesn’t require drying—unlike some other plastics that add time and cost to every cycle.
