Grade:RE932
Product:Hot Melt Adhesive granules for Various Multi-layer Barrier Sheets
Decriptions
Hot-melt adhesives are as numerous as they are versatile. In general, hot melts are applied by extruding, rolling or spraying, and the high melt viscosity makes them ideal for porous and permeable substrates. HMA are capable of bonding an array of different substrates including: rubbers, ceramics, metals, plastics, glass and wood.
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.
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.

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.
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.
Packages and Storage
