JH-2219 is a liquid amphoteric strength enhancer designed for pulp molding applications. It forms ionic bonding networks on fiber surfaces to improve stiffness, tensile toughness, and compression resistance of molded products, especially when using recycled waste paper pulp.
Recycled fiber optimized: Formulated for egg trays, fruit trays, and industrial buffer packaging made from waste paper pulp, eliminating brittleness. (source: selling_point 2)
Easy handling: Water-based liquid, dilutes in cold water and mixes uniformly without heating. (source: selling_point 3)
Compatible with wet-end systems: Works alongside sizing agents and defoamers without flocculation or system blockages. (source: selling_point 4)
Dimensional stability: Reduces warping and cracking during hot pressing and drying. (source: selling_point 5)
Eco-friendly and food-safe: No formaldehyde, non-toxic, odorless; suitable for food-grade pulp tableware. (source: selling_point 9)
