FAQ

What melt flow index should I choose for blown film applications?
For blown film, select MFI 0.3-1.0 for good bubble stability and dart impact strength. Higher MFI (1.5-4.0) works for cast film where bubble stability isn't critical. Colorado Sun Inc can recommend specific grades based on your film thickness and line speed requirements.
How do I prevent melt fracture in pipe extrusion?
Reduce shear rate by lowering screw speed, increase melt temperature gradually, or switch to higher molecular weight resin with lower MFI. Also check for contamination or moisture that can cause surface irregularities. Processing aids can help but may affect pipe pressure ratings.
What causes poor layer adhesion in coextrusion?
Common causes include temperature mismatch between layers (keep within 20°C), contaminated surfaces, incompatible polymers without tie layers, or insufficient residence time in the die. Use corona treatment or tie layer resins for dissimilar polymer combinations.
How often should I clean my extrusion die?
Clean frequency depends on resin type and processing conditions. For clean polyolefins, every 24-48 hours is typical. For filled compounds or recycled content, clean every 8-12 hours. PVC requires more frequent cleaning due to thermal degradation. Watch for streak formation as your cleaning indicator.
