Lotader^® resins are reactive polyethylenes. Lotader resins reactivity is due to the presence of glycidyl methacrylate (GMA) or maleic anhydride (MAH) groups. Lotader resins are characterized by reactivity, crystallinity and melt fluidity, making them easy to use and readily compatible with various thermoplastics such as polyamides, polyesters, PC alloys, and polyethylenes. Lotader resins offer excellent thermal stability during processing.

NEW MULTIPURPOSE ADHESIVES FOR EXTRUSION LAMINATION

Two multipurpose adhesives give extrusion lamination flexible-packaging applications extra bonding power. Lotader 4403 and 4503 help bond a wide variety of polar and nonpolar polymers, as well as metal to plastics, without a primer. They adhere to difficult substrates such as PP, PA, and PET oriented films, cellophane, PVC films, PVDC coating, and printed films. These Lotader grades also adhere onto PA and EVOH in coextrusion applications.

These acrylate-and maleic anhydride-containing materials provide easy processing and equipment cleaning, good organoleptic properties, and granules that are insensitive to moisture. They can be used over a wide temperature range without risk of edge sticking. There is also neither corrosion nor crosslinking risk during processing.

Lotader terpolymers are intended for the following applications:

Impact Modifiers for Engineering Plastics

• Impact modifier for polyamides
  
  Lotader^® 4700 and 4720 resins are used in the manufacture of impact-resistant and super-tough polyamides for the electronic and automotive industries. Due to their low molecular weight, Lotader® resins can be processed on single or twin-screw extruders over a wide temperature range.
  
  Lotader^® 4700 and 4720 resins have been designed for injection molding compounds. Lotader^® 3210 and 3410 resins are typically used as impact modifiers for extrusion grades of PA compounds.

• Impact Modifiers for Thermoplastic Polyesters
  
  The epoxide functionality of Lotader^® GMA resins make them well suited as impact modifiers for thermoplastic polyesters (PBT, PET and alloys PC/PBT). Lotader^® GMA resins can be dispersed into a very fine elastomeric phase in PBT and PET resins, improving impact resistance.
  
  Lotader^® AX8900 resin is an impact modifier for extrusion or blow molding grades of polyesters.
  
  Lotader^® AX8920 resin is an impact modifier for injection molding grades of polyesters.

• Impact Modifiers for High Flow Compounds
  
  Polyamides and polyesters, compounded with a combination of Lotader^® and Lotryl™ resins, have shown a good balance of impact resistance and melt fluidity. For more information about the Lotader^®-Lotryl™ combination, visit the Lotryl™ resins page.
  
  In 2003 Lotader^® XX1336 resin was introduced as an improved impact modifier for polyamide 6. Compared to Lotader 4700, PA compounds using Lotader XX1336 have better ageing resistance and higher fluidity

• Compatibilizing and Coupling Agents
  
  Lotader^® AX resins are used as compatibilizers of polyolefins and thermoplastic polyesters (PET, PBT). Lotader^® AX8840 resins are recommended to compatibilize PET and polyethylene.
  
  Lotader^® 3210 and Lotader^® 3410 resins are used as compatibilizers of polyethylene and polyamide 6 and 6.6.
  
  Lotader^® 3210 and 3410 resins are used in the manufacture of halogen-free self-extinguishing cables.
  
  Lotader^® 8200 resins are used in the production of high hardness, highly carbon black filled, EPDM elastomers.
  
  Cable Compounds Presentation

Lotader^® MAH or GMA resins can be cross-linked to increase their resistance to extreme temperatures for use in cable, automotive, and hot melt applications.

• Flexible Packaging
  
  

Lotader^® 3210 resin can be used as tie layers in coextrusion coatings onto aluminum. It can be used pure or blended with LDPE.

Lotader^® 4210 resin, with a higher reactivity than Lotader^® 3210 resin , is more effective as a tie layer for extrusion lamination.

Lotader^® 3410 and Lotader^® 3430 resins, with lower crystallinity, adhere better to plastic films such as OPP and unprimed PET.

Lotader^® 2210 resin can be coextruded with polyamides to make packaging materials for meats and cold cuts.

Adhesives: Pipeline Coatings, Automotive Liners and Hot Melts

• Pipeline coatings
  
  Pipelines are protected against corrosion by an epoxy layer and are protected mechanically by polyolefin coatings. Lotader® resins are used as an intermediary layer, ensuring a solid link between these two coatings. The available grades are:
  
  

Lotader^® 3200 resin for operating temperatures of up to 60°C

Lotader^® 2100 resin for operating temperatures of up to 70°C

Note: for higher temperatures, 80° and 110°C, grafted PE- or PP-based Orevac™ resins can be used.

• Thermoadhesive films

Lotader^® 2308 resin is used in the interior liners of automobiles.

• Hot melt adhesives

Lotader^® 5500 and 7500 resins have greater fluidity and can be used in hot melt adhesive formulations for packaging, woodworking, and bookbinding.
