Adhesive - Rallychem

Provide highly advantageous hot melt adhesive adjustment solutions

Wax is the most effective regulator for the fluidity of hot melt adhesives. Rallychem offers a refined range of waxes, including Fischer-Tropsch, polyethylene, polypropylene, and polar oxidized polyethylene, featuring high melting points and a uniform molecular weight distribution. These are designed to facilitate adjustment of adhesive formulations and flow, accommodating the requirements of various application environments and sizing processes.

Dominasi

Free control of opening and curing time

For the hot melt adhesive formulation system, the addition of wax always shortens the opening time, and the degree of influence varies with the nature of the wax. The wide range of Rallychem waxes with different melting points and viscosities, makes it easy to adjust the formulation according to the actual application.

Enhance tensile strength and flexibility

When compatible, wax can enhance the strength and modulus of hot melt adhesives. Rallychem's narrowly distributed wax products can enhance the flexibility of hot melt adhesives, as it is readily compatible with the ethylene segments within EVA.

Improved regulatory adhesion and wettability

When bonding porous materials, if the hot melt adhesive is overly viscous, it may consolidate before fully penetrating the substrate, leading to inadequate bonding. Rallychem's refined FT and PE waxes offer lower viscosities, effectively enhancing the adhesive's wettability. With polar substrates, using oxidized polyethylene waxes containing polar groups can enhance bonding properties.

Pertanyaan yang Sering Diajukan

Why are waxes the best knobs to tune flow?
+

Because they control the whole “flow → wetting → set” chain.
· Lower hot viscosity, spread better
· Lubricate during flow
· Form thin solid phases on cooling for slip and green strength
How do you dial open time and set speed?
+

· High-melt, high-viscosity waxes (some PP waxes): shorten open time a lot
· Low-melt, low-viscosity waxes (FT/PE waxes): milder effect
· Polar/grafted waxes: change interphase behavior and gelation
Pick by substrates and process, then finetune with quick trials.
Will wax make the glue brittle?
+

It can—if it’s incompatible or overdosed. Use compatible, narrowdistribution or functional waxes and step up dose gradually. Done right, you can lift strength/modulus and still keep flexibility.
