Name: Arkema Lotader 4503 Toughener Compatibilizer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Arkema Lotader 4503 Toughener Compatibilizer

Enhances impact resistance and ductility in polyolefin-based blends without compromising stiffness.
Acts as a reactive compatibilizer between polyolefins and polar polymers (e.g., PA6, PET, EVOH) via maleic anhydride functionalization.
Improves interfacial adhesion in multilayer coextruded structures, supporting superior delamination resistance.
Offers excellent melt processability and thermal stability up to 280 °C during extrusion and injection molding.
Enables recyclability of mixed polymer streams by stabilizing phase morphology during reprocessing.

Typical Applications Of Arkema Lotader 4503 Toughener Compatibilizer

Automotive interior trim components requiring high toughness and scratch resistance.
Multilayer barrier packaging films (e.g., PP/EVOH/PP) for food and pharmaceutical applications.
Toughened polypropylene compounds for durable consumer goods and industrial housings.
Recycled polyolefin blends incorporating post-consumer or post-industrial waste streams.
Overmolding adhesion promoters for PP-to-PA or PP-to-TPE interfaces.
