What are the main requirements on PP resin in LFT process?
PP resin with better flowability is required. If the melt flowability rate is too low, the mechanical properties are optimized while the flowability will be bad; if the melt flowability is too high, the mechanical properties will be compromised. So it is vital to choose the proper PP resin. It is recommended that the melt flowability rate should be 50-80g/min.
