Concept, performance, and co extrusion characteristics of coupling agents

Coupling agent is a thermoplastic resin that can be extruded to bond different types of materials. Adhesive is commonly used in co extrusion. According to usage, the peel strength of the adhesive must reach 50g/15mm width.

Performance and co extrusion characteristics of coupling agents

Overall requirements:All materials come from a wide range of sources and have a significant MFR; Typically, the thickness is 3-5&Before shutting down, it is necessary to clean thoroughly

Ionic bond polymer:Has good adhesion with LUPE, PA, EVA, and LURE; Improving the mechanical properties of thin films

Modified EVA:With LIRE LLDPE, PA, EVA, EVOH form a composite structure; Very good processability

Modified LLDPE:Good processability, wide source, and diverse varieties; High pressure can be generated in the extrusion system
