NOVA® KEY FACTS





1. POLAR-CO-MONOMER GRAFTED POLYOLEFIN
2. EXTRUDABLE
3. TIE RESIN
4. ADHERING TO BARRIER MATERIALS
ETHYLENE VINYL ALCOHOL (EVOH), POLYAMIDE (PA), METALS

NOVA® resins are modified polyolefins with functional groups, designed to bond to a variety of polyolefins, ionomers, polyamides, ethylene vinyl alcohol (EVOH), polyester (e.g. PET) and metals. They serve as tie layer in multilayer applications such as films, sheets, bottles, tanks, pipes, tubes and others and, thus, help to combine the excellent properties of incompatible materials, as, for example, gas barrier resins and moisture barrier resins. NOVA®  resins are also used as coupling agents, compatibilizers and impact modifiers in various types of composites. NOVA®  adhesives are thermoplastics and can be as easily processed as any other polyolefin by (co-)extrusion or powder coating. NOVA® is famous for its excellent quality and is therefore the world’s leading polyolefin-based adhesive. Production sites all over the world  assure a constant and convenient availability of our top quality adhesives. 

Multilayer Structure with NOVA®


  • 1

    STRONG ADHESION

    By thermal reaction NOVA® adheres to ethylene vinyl alcohol (EVOH), polyamide (PA), polyester (PET), polyolefins (PE, PP) and metals.

  • 2

    ADHESION DURABILITY

    NOVA® shows excellent long-term adhesion strength even after secondary processing like pasteurization, hot filling, boiling and sterilization.

  • 3

    POLYOLEFIN-LIKE PROPERTIES

    Since NOVA® is based on polyolefins or copolymers, it retains the physical properties of each polyolefin or co-polymer including mechanical strength, heat resistance, chemical resistance and recyclability.

  • 4

    EASY PROCESSING

    NOVA® , a thermoplastic, can be processed as easily as any other polyolefin by the following methods:

    1. FILM CO-EXTRUSION (CAST AND BLOWN FILM)
    2. CO-EXTRUSION BLOW MOULDING
    3. SHEET CO-EXTRUSION
    4. TUBE CO-EXTRUSION
    5. CO-EXTRUSION COATING
    6. METAL COATING
    7. CO-INJECTION

 Automotive Applications

NOVA® IS THE GLOBALLY LEADING TIE RESIN IN CO-EXTRUDED PLASTIC FUEL TANKS

AUTOMOTIVE DEMANDS
Every vehicle contains about 30,000 parts. Industry demands for lightweight, recyclable parts have increased in line with needs for environment-friendly vehicles

STRUCTURE OF MULTILAYER PLASTIC FUEL TANK
HDPE / NOVA® / EVOH / NOVA® / REGRIND / HDPE

NOVA®   is used as a tie layer resin in integrated plastic fuel systems. Available in pellet form, this high performance adhesive resin shows superior long term adhesion, toughness, aging resistance and enables fuel system suppliers and OEMs to deliver fuel components with low permeation and superior durability.

LOW-PERMEATION IN FUEL SYSTEMS

For many years, NOVA® Chemicals has been working with automotive suppliers to develop improved multilayer plastic fuel systems. The tie layer resin is used extensively by the automotive industry worldwide, and NOVA® Chemicals is continuously making improvements to accommodate alternate fuels and advances in fuel system technologies.  The industry‘s premier multilayer fuel system components benefit from the application of EVOH as low-permeation barrier material. By chemical reaction to the EVOH, NOVA® enables the cost efficient production of multilayer tanks.  Main feature of these co-extruded tanks is a consistent permeation resistance to evaporative emissions. This superior resistance to gasoline permeability ensures that OEMs meet environment, regulatory and industry requirements which are constantly reinforced.
