PP
Polypropylene excels where repeated flexing and heat resistance are needed. Its fatigue endurance allows living hinges to open and close thousands of times without failure, making it a staple in flip‑top lids, appliance housings, and reclosable containers. Its low moisture absorption ensures dimensional stability in humid environments.
Beyond consumer goods, PP finds applications in specialty fibers and non‑woven fabrics for filtration and hygiene products. Its low density also contributes to lightweight automotive and industrial components where fuel efficiency or ease of handling is critical.
