Name: Tosoh Tosoh Silica P8 Polyethylene-Polyamines
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Tosoh Tosoh Silica P8 Polyethylene-Polyamines

Highly functionalized silica surface grafted with branched polyethylene-polyamine chains for enhanced chelation and amine density.
Excellent dispersibility in aqueous and polar organic media due to balanced hydrophilic-hydrophobic character.
Thermally stable up to 200 °C, retaining structural integrity during polymer processing and coating curing.
Controlled amine functionality enables precise pH-responsive behavior and tailored reactivity in catalytic or adsorption systems.
Low extractables and high batch-to-batch consistency, meeting stringent requirements for electronic and pharmaceutical-grade applications.

Typical Applications Of Tosoh Tosoh Silica P8 Polyethylene-Polyamines

Heavy metal ion capture and recovery in industrial wastewater treatment systems.
Catalyst support for selective hydrogenation and CO₂ conversion reactions.
Functional filler in high-performance epoxy composites for aerospace and electronics encapsulation.
