When you pick a high temperature urethane for prototypes, you should look at how well it handles heat and how it works. The chart below lists materials like AFP3320, AFP3400, AFP3600, and PT8958. It shows their hardness and the best ways to use them: Material Hardness (Shore D) Heat Resistance Applications AFP3320 80 High HVAC Components, Underhood Automotive Parts, Industrial Machinery Housings AFP3400 70 Moderate Living Hinges, Flexible Connectors, Dynamic Seals AFP3600 ~82 High Lenses, Light Housings, Backlit Panels PT8958 85 High Medium to Large Medical Device Housings, Components for Diagnostic Equipment Heat resistance affects how strong the material is.…
You must pick the right flame retardant resin. Match its UL 94 rating to how you will use your product. Also, match it to how you will make your product. This choice keeps your product safe. It helps you follow the rules. UL 94 ratings depend on how thick the material is. Always check the UL Yellow Card. If you choose the right retardant early, you avoid expensive changes later. This keeps your project moving forward. Balance flame resistance, strength, how you make it, safety, and cost. This makes your product reliable and follows the rules. Key Takeaways Pick the…
