Concentrated tie-layers offer cost-effect solutions.

Switching from traditional tie-layers materials to tie-layer concentrates offers a range of both commercial and technical advantages in PA and EVOH structures.

Using concentrated tie-layers gives you the ability to tune individual formulations giving ideal adhesion at the lowest possible cost by simply adjusting the dilution rate. Our most cost-effective concentrated tie-layer grade is OREVAC? 18341 which is a maleic anhydride grafted linear low-density polyethylene. Switching to concentrated tie-layers also allows reduced stock holding due to dilution with your own LLDPE.

In multi-layer film, OREVAC? 18341 develops a reliable bonding strength in co-extrusion processes between polyethylene and different materials (PA, EVOH …). Containing a higher amount of grafted reactive functionalities compared to standard LLDPE based co-extrusion tie resins, it can be used blended with other polyolefins.

OREVAC? 18341 generally is diluted in your own polyethylene at between 20% and 30% for EVOH structures and between 10% and 20% for PA structures - although being a concentrate, you have complete control over the dilution rate in your applications and lower dilution rates are possible in some applications.

OREVAC? 18341 is designed to be blended with standard polyethylenes and can be converted on standard blown and cast film lines (and has high viscosity which is good for blown extrusion). OREVAC? 18341 also has good regulatory status.

Other applications for OREVAC? 18341:

• OREVAC? 18341 has been designed to develop a reliable bonding strength between polyethylene or ethylene co-polymers and mineral fillers such as aluminum trihydrate (ATH) or magnesium hydroxide (MDH). It is an effective coupling agent for halogen-free flame retardant compounds using high loadings of mineral fillers, such as compounds for insulation and sheathing of wires and cables.
• OREVAC? 18341 can also be used as a tie-layer in pipe-coating technology for multi-layer structures. It has been designed to develop a reliable bonding strength onto Fusion Bonded Epoxy (FBE) steel pipe protective layer.
