FAQ
Q: What are the advantages of polyester polyol soft foam compared with polyether polyol soft foam?
A: Soft foams produced from polyester polyols are generally more resilient, durable and cost effective. They are superior to polyether polyols in hydrolysis and oil resistance, meaning that they maintain more stable performance in wet or oily environments. In addition, polyester polyol foams tend to have a higher density range, providing a finer touch and support.
Q: How to adjust the density and hardness of soft foam?
A: The density and hardness of soft foams can be controlled by adjusting the type, molecular weight, functionality, and ratio of polyester polyols to isocyanates. Increasing the amount of polyester polyols or choosing a higher molecular weight polyester polyol will usually make the foam harder and denser; In contrast, a softer, less dense foam is obtained.
Q: How long is the service life of polyester polyol soft foam?
A: The service life of polyester polyol soft foam depends on the application environment, frequency of use and maintenance. In general, high-quality polyester polyol soft bubbles have good aging resistance and can be used for many years under normal conditions while maintaining their physical properties, especially in terms of compression and resilience.
