Description

OREVAC® 18341 is a maleic anhydride (MAH) grafted linear low-density polyethylene.

• OREVAC® 18341 has been designed to develop a reliable bonding strength between polyethylene or ethylene copolymers 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 multilayer structures. It has been designed to develop a reliable bonding strength onto FBE(Fusion Bonded Epoxy) steel pipe protective layer
• In packaging market, OREVAC® 18341 develops a reliable bonding strength in coextrusion processes between polyethylene and different materials (PA, EVOH …).

Containing a higher amount of grafted reactive functionalities compared to standard LLDPE based coextrusion tie resins, it can be used blended with other polyolefins.

Processing

OREVAC® 18341 is suitable for the production of cable compounds with most common types of equipment (internal mixer, co-kneader, twin screw extruder). When used for pipe coating technology, OREVAC® 18341 is to be processed like a standard polyethylene resin. Typical extrusion temperature settings could be:
Zone 1: 180-190°C
Zone 2: 190-200°C
Zone 3: 200-210°C
Zone 4: 210-220°C
Exit: 220-230°C
Fittings-Channels: 220-240°C
Die: 220-240°C
Final profile and settings will depend on the line and the multi-layer structure being run.

Storage, Handling & Safety

OREVAC® 18341 should be stored in a ventilated area, away from heat, humidity and direct sunlight. Improper storage conditions may cause degradation and could have consequences on physical properties of the product.
