Grade:RE932
Product:Hot Melt Adhesive granules for Various Multi-layer Barrier Sheets
Decriptions
Hot Melt Adhesive (HMA), also known as Hot Melt Polymer is a 100% solid thermoplastic resin that liquefy when heated. When it cools, hardens on surfaces, it can bond two non-porous materials within seconds. It contains no solvents, no water, so it is eco-friendly and won’t be moldy. It is a form of thermoplastic adhesive that is commonly used for various multilayer barrier sheets.
RE932 is a maleic anhydride functionalized polypropylene mixture, easy to form film,with excellent processablility and adhesive strength, realizes the bonding of polypropylene resin and EVOH resin.
Hot melt adhesive granule is a modified polyolefin with functional groups to bond firmly to common Polyolefin, Polyamide, Ethylene-vinyl -alcohol (EVOH).Since polyolefin itself have no functional groups, it does not adhere to other materials. So we incorporate functional groups into the Polyolefin-Resin to endow the outstanding adhesiveness to other materials without losing all the characteristic benefits of the polyolefin.

Advantages
a. Strong Adhesion:Adhere to EVOH etc. strongly by thermal reaction. And it bonds strongly to PP with EVOH resins and keeps its polyolefin characteristics also.
b. Durability:It can maintain excellent adhesiveness under the the harsh conditions in the thermal aging , hot water, cold water, low temperature,etc.
c. Simple and easy processing: It can be processed in conventional extrusion equipment which is designed for plyolefin processing,doesn’t require special production equipment and the process condition is similar to common polyolefin.
Chemical Structure
Composition: Maleic Anhydride fuctionalized polypropylene mixture.
Application
RE932 adhesive resin is widely used for Multi-layer high barrier cast sheet products, such as milk cups, jelly cups, etc.
