Tuning High and Low Temperature Foaming Behavior of Linear and Long-Chain Branched Polypropylene via Partial and Complete Melting

Mu Sung Kweon et al.

Summary: This study investigates the foamability of linear and branched polypropylene (PP) resins using two different melting methods. The results show that at high temperatures, both methods yield similar expansion ratios, with the PP resin with higher strain hardening ratio exhibiting the highest expansion ratio. However, at low temperatures, Method 2 significantly improves the foamability of all resins and results in a more uniform cellular structure over a wider temperature range.

Effects of pressure drop rate and CO2content on the foaming behavior of newly developed high-melt-strength polypropylene in continuous extrusion

Eric Kim et al.

Summary: Systematic studies were conducted on the foamability of a novel high-melt-strength long-chain branched polypropylene under supercritical CO2. The foam expansion was controlled by adjusting the temperature at the die exit, and the results showed that the expansion ratio was influenced by both the amount of CO2 and the die temperature. Additionally, the cell density was found to be dependent on the pressure drop rate and the dissolved CO2 amount, with the latter showing a more noticeable effect at lower pressure drop rates.

Recent progress in micro-/nano-fibrillar reinforced polymeric composite foams

Chongxiang Zhao et al.

Summary: A novel method of making microcellular foams with micro-/nano-fibrillar reinforced polymeric composites (M/NFC) is introduced in this work, which offers improved cellular structures, excellent mechanical properties, and enhanced thermal insulation properties compared to conventional foams. The incorporation of micro-/nano-size fibrils strengthens the melt strength, induces faster crystallization, and improves the mechanical properties of the reinforced foams, making them ideal for structural applications and insulative products.
