PP fibers need to be hardened for some applications, such as carpet fibers requiring a good lodging resistance property and rebound resilience. Hardening masterbatches give the PP a higher modulus to improve the stiffness.
Features of Hardening masterbatches:
Good compatibility with polymers. No change to the polymer's original color . Improve the luminance brightness and transparency of products. Easy to use, blend with PP directly before spinning.
