Delrin 100P Toughness, Elongation, and Structural Modulus Profile<\/h2>\n

Delrin\u00ae 100P NC010 is a high-viscosity, unmodified acetal homopolymer. Due to its long polymer chain length, it offers the highest level of toughness, elongation, and fatigue endurance within the homopolymer acetal family:<\/p>\n\n\n\n\n\n\n\n

Specialized Dynamic Process Configurations for Delrin 100P<\/h2>\n

With low melt flow and extreme polymer toughness, Delrin 100P is engineered to process reliably in high-stress tools:<\/p>\n\n\n\n\n\n\n\n

Delrin 100P Processing Matrix & Melt Control Checklist<\/h2>\n

Because Delrin 100P has high molecular weight, processing its low-melt-index resin requires precise gate geometries and high-capacity degassing:<\/p>\n

\n
\n

1. Viscous Melt Delivery & Large Gates<\/p>\n

With a low melt index of 2.4, Delrin 100P is highly viscous. Gates must be sized generously (minimum 70% of part wall thickness) and sprues polished to avoid dynamic pressure drops and high shear stress, which can cause surface splay and gate blush.<\/p>\n<\/div>\n

\n

2. High-Capacity Mold Exhaust & Degassing<\/p>\n

Formaldehyde outgassing occurs naturally. Low-MFR melts residing longer in the barrel require rapid air exhaust. Jucheng machines highly ventilated venting grooves (0.020mm) using premium S136 stainless steel mold cavity blocks to prevent gas burns.<\/p>\n<\/div>\n

\n

3. Crystalline Shrinkage Compensation<\/p>\n

Like standard POM-H, Delrin 100P shrinks heavily (1.80% to 2.20%). We employ Moldflow simulation to locate gate inputs strategically, applying progressive packing pressures to feed the center core and eliminate internal shrink voids.<\/p>\n<\/div>\n

\n

4. High-Temp Oil Temperature Control<\/p>\n

To optimize crystallinity and surface gloss, we keep mold temperatures at 80\u00b0C to 120\u00b0C (176\u00b0F to 248\u00b0F) using pressurized temperature controllers. Low mold temperatures prevent the crystalline phase from forming correctly, resulting in part warpage.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
