Insoluble fiber is a type of dietary fiber that does not dissolve in water. Found in foods like whole grains, nuts, vegetables, and wheat bran, it helps promote regular bowel movements and prevent constipation by adding bulk to the stool. Unlike soluble fiber, which forms a gel-like substance in the gut and can help lower cholesterol and blood glucose levels, insoluble fiber stays relatively intact through the digestive system. This characteristic aids in speeding up the passage of food and waste, contributing to a healthy digestive tract. Incorporating insoluble fiber into one's diet is beneficial for digestive health and can be part of a balanced diet to maintain or improve overall health. It's important to increase fiber intake gradually to allow the body to adjust, and to consume plenty of water.

Polypropylene (PP), a widely used plastic in various applications, from packaging materials to automotive parts, has a UL 94 flammability rating that typically ranges from HB (slow burning on a horizontal specimen; flame stops within 30 seconds on a specimen of <3mm thickness) to V-2 (burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed). This rating indicates that while polypropylene is flammable, it doesn’t easily propagate fire under certain conditions. However, its actual fire behavior can significantly depend on its form, thickness, and the presence of flame retardants. Products made from polypropylene are not designed for high-temperature applications or exposure to open flames. Considering safety and compliance, it’s crucial to understand the specific flammability rating of the polypropylene material used in your application and take appropriate fire safety measures.
