Impact of Environmental Humidity on the Shrinkage Rate of PP Flame-Retardant Insulation Film during Extrusion Molding and Compensation Methods

Introduction

Polypropylene (PP) flame-retardant insulation film is extensively used in industries where high electrical insulation and flame resistance are required. However, the shrinkage rate of the film during the extrusion molding process is a critical parameter that affects its dimensional stability and mechanical properties. One of the key external factors influencing shrinkage is environmental humidity. Understanding how humidity impacts shrinkage and implementing appropriate compensation methods is essential for ensuring the final product’s quality and performance.

How Environmental Humidity Affects PP Flame-Retardant Insulation Film Shrinkage

  • Moisture Absorption by Polymer Pellets: Although PP is generally hydrophobic, certain flame-retardant additives and fillers can absorb moisture from the air.

  • Changes in Extrusion Cooling Rate: High humidity can alter the cooling efficiency of the extrusion process.

  • Impact on Film Crystallinity: Environmental moisture can interfere with nucleation during polymer crystallization.

  • Electrostatic Charge and Film Handling: Increased humidity can reduce electrostatic buildup, affecting the film stretching process.

Compensation Methods for Shrinkage Due to Humidity

  • Pre-Drying of Raw Materials: Use desiccant dryers to remove moisture from PP pellets before processing.

  • Optimized Extrusion Process Parameters: Adjust the melt temperature and extrusion speed to counteract moisture-related variations.

  • Controlled Production Environment: Maintain stable relative humidity levels in the production facility.

  • Use of Humidity-Resistant Additives: Incorporate moisture-scavenging additives to reduce humidity-related shrinkage effects.

  • Post-Processing Compensation Techniques: Implement annealing to relax molecular stresses.

Conclusion

Environmental humidity plays a crucial role in determining the shrinkage rate of PP flame-retardant insulation film. Manufacturers can employ strategies such as pre-drying raw materials, optimizing process parameters, controlling environmental humidity, and using moisture-resistant additives to ensure high-quality production.
