Product Introduction:

Interlayer adhesives are non-polar polymers containing polar groups. Today, various types of interlayer adhesives with different chemical structures have been developed. In multilayer compounds, due to the use of (polar/non-polar) groups and the incompatibility of these groups, it is necessary to use interlayer adhesives in order to maintain properties and processability. Interlayer adhesives are combined with polyolefin base along with maleic compatibilizers during a reactive extrusion process to connect non-polar groups such as polyethylene and polypropylene to polar groups such as aluminum, ethylene vinyl alcohol (EVOH), polyamide (PA).

Technical Specifications:

This product is produced as interlayer adhesives with a special formulation under the reactive extrusion process including several different components

of the base polymer. These components are:

1) linear low density polyethylene LLDPE, 2) polyolefin elastomer POE, 3) high density polyethylene HDPE, 4) polyolefin base compatibilizers, 5) high impact polystyrene HIPS, 6) styrene butadiene styrene SBS and 7) thermal stabilizers, etc. This process takes place under fully controlled temperature conditions in a twin screw extruder with a special screw design. In practice, in the production process of this product, an extruder has been converted into a chemical reactor, and the various components of the reaction must complete the reaction in less than 50 seconds before exiting the extruder.

Advantages:

High quality at a competitive price
