WAX FOR HOT MELT ADHESIVE

HOT MELT ADHESIVES COMPOSITIONS

Hot meld adhesive compositions : One or more ethylene based copolymers, no greater than about 27 % by weight of  a tackifying agent and  a wax.

Hot melt adhesive compositions are solid at room temperature and melt at higher temperatures. Hot melt adhesives compositions can be used in packaging applications e.g. to close box tops and also to form cases, cartons and / or trays. 

Hot melt adhesives used in packaging should exhibit good bond formation across a broad temperature range, heat resistance, and a fast set time to be commercially useful.

Hot melt adhesive compositions for packaging are made from a variety of different base polymers including ethylene based copolymers ( e.g. ethylene vinyl acetate).  

Hot melt adhesive compositions for packaging can include tackifying agent and wax as well.  The tackifying agent used with ethylene vinyl acetate type polymers is often a polar tackifying agent such as e.g. rosin or functionalized terpene based resin. In some applications, it can be desirable to use a hydrogenated hydrocarbon based tackifying agent to lower the color of the hot melt adhesive. 

At times, it would further be useful to be able to limit the tackifying agent in the hot melt adhesive composition.

HOT MELT ADHESIVE COMPOSITIONS AS FOLLOWS :

·         > Ethylene copolymer derived from ethylene ( Ethylene vinyl acetate )

·         > Ethylene comonomer ( Vinyl acetate, alkyl acrylate, alkyhl methaacrylate, Tackifying agent

·         > Additives : antioxidants, stabilizers, additional polymers, adhesion promoters, UV light stabilizer, rheology 

        modifiers, corrosion inhibitors, colorants ( e.g. pigment and dyes ), fillers, flame retardants, nucleating 

        agents and combinations thereof.

ETHYLENE BIS STEARAMIDE

 Internal-External Lubricant for plastic

Ethylene bis stearamide (EBS) is an organic compound with the formula (CH₂NHC(O)C₁₇H₃₅)₂. It is a waxy white solid and is also found as powder or beads that is widely used as a form release agent. The compound is derived from the reaction of ethylenediamine and stearic acid. It is a cheap, white solid of low toxicity that provides a slippery coating for a variety of applications.


EBS is a synthetic wax used as a dispersing agent or internal/external lubricant for benefits in plastic applications to facilitate and stabilize the dispersion of solid compounding materials to enhance processability, to decrease friction and abrasion of the polymer surface, and to contribute color stability and polymer degradation.
It is also used in process industries as release agent, antistatic agent and antifoaming agent for the production of thermoplastics, wiring, and paper. It is used in powder metallurgy.

Wax EB-FF ( EBS ) is an amide type of wax which has high melting point and special property showing the low viscosity in molten form. In molten form under high temperature, it's compatible well with resin or solvents. Wax EB-FF is a lubricants and/or mould releasing agent for thermoplastic resin such as ABS resin, PS, PVC and so fort.
