ADMER™ is used as an adhesive layer in numerous applications which consist of multiple layers of barrier materials. Not only does the adhesive resin ensure that manufacturers meet environmental, regulatory and industry requirements but it also enhances adhesive performance and durability.

Automotive Applications

ADMER™ 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 Barrier Material for Fuel System Applications

For many years, Mitsui 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 world wide, and Mitsui Chemicals is continuously making improvements to accommodate alternate fuels and advances in the fuel systems including P-ZEV systems.

Adhesive Resin for Multilayer Fuel System Applications

The industry's premier multilayer fuel system components benefit from the application of this low-permeation barrier material.

• Plastic Fuel Tanks
• Fuel Lines
• Fuel Filler Pipes
• Fuel Connectors

The adhesive resin compliments the barrier materials and allows multilayer construction with the toughness and adhesion required to deliver consistent permeation resistance preventing evaporative emissions without weakening fuel system performance. Its superior resistance to gasoline permeability ensures that OEMs meet environment, regulatory and industry requirements by preventing evaporative emissions of fuel gas while maintaining the structural integrity of the fuel system.

Packaging Applications

Adhesive Resin for Cosmetic Packaging Applications

The tie layer adhesive can be extruded by applying the co-extrusion process for film, cup, tray, tube and bottle applications. The adhesive resin is featured in personal care and consumer packaging for skincare and body care and toiletries such as:

• Body lotion containers
• Make up bottles
• Oval and round tubes

Adhesive Resin for Pharmaceutical Packaging Applications

The ADMER™ Adhesive resin facilitates the development of high performance healthcare packaging, which can be used in applications such as:

• Tubing
• PTP packaging
• Bottles

Adhesive Resin for Food Packaging Applications

The use of this low permeation barrier material in packaging structures restricts the passage of oxygen, flavor and odor permeation. Currently, the adhesive resin is used as a permeation barrier in bottle and container packaging for:

• Ketchup
• Mayonnaise
• BBQ sauce
• Salad dressing
• Pudding
• Meat
• Cheese
• Pasta sauce
• Soup
• Applesauce
• Beverages

ADMER™ adhesive resin exhibits durable adhesion during and following secondary processing such as thermoforming, sterilization and orientation. The co-extrusion coating of ADMER™ with other plastics onto paper or foil has yielded other opportunities in the food packaging area, which the company is pursuing. ADMER™ grades are certified and comply with FDA, EEC directives, and Japan Hygienic Olefin and Styrene Plastics Association (JOSPA) regulations. ADMER™ grades may be used in direct food contact.

Industrial Applications

In industrial markets, ADMER™ is ideal for a number of uses including floor heating pipe, aluminum sheathe and bottle applications.

Oil and Gas Pipe Applications

In the oil and gas sectors, pipeline bondings and coatings are expected to perform under severe conditions and extreme temperatures. Mitsui Chemicals has developed a four grade steel pipe bonding series of ADMER™ Adhesive Resin, each of which has been designed to meet the demanding requirements of toughness, adhesion and extremes of service temperature of pipes. ADMER™ can be easily processed by co-extrusion with polypropylene or polyethylene with circular die for middle or small diameter steel pipes, and with flat die for larger diameter steel pipes.

ADMER™ QF551A and QB520A – Designed for bonding to steel pipes with polypropylene

There are two grades of ADMER™ which are modified polypropylene with an anahydride group designed for bonding steel with polypropylene. QB520A is the standard grade and QF551A is the advanced grade, both of which can be used at operating temperatures ranging from 200°C (390°F) to 270°C (540°F). Both grades offer properties and adhesion performance appropriate for steel pipe and pipeline requirements.

ADMER™ NF458A and AT1414 - Designed for bonding to steel pipes with Polyethylene

There are two grades of ADMER™ which are modified polyethylene based with an anhydride group designed for bonding steel with polyethylene. NF458A is the standard grade, recommended to use an epoxy coating between the steel pipe and the ADMER™ (3 layer system). AT1414 is the advanced grade, intended to eliminate the epoxy coating process (2 layer system). Even though, the application of an epoxy coating does improve adhesion, cost savings can be realized by using the AT1414 grade. These types of steel pipe bonding and coating materials are used due to their excellent mechanical performance and high temperature resistance. These grades can be used at operating temperatures ranging from 180°C (355°F) to 300°C (570°F)

Process, Properties and Adhesion Performance of ADMER™ NF458A and AT1414

ADMER™ AT2305A - Designed for Binding or as a Coupling Agent for Fiber Reinforced Plastics (FRP)

ADMER™ AT2305A is a modified polyolefin which contains maleic anhydride in its main chain, enabling the material to act as a binder or coupling agent for glass fiber reinforced polypropylene (GFRP) and carbon fiber reinforced polypropylene (CFRP). Admer has excellent reactive character, and the addition of the Admer AT2305A improves tensile strength and impact strength. AT2305A takes effect with the addition of approximately a third of the quantity required for conventional materials. Long run processability is feasible because the material contains less ungrafted monomer. This translates into less char after a long run operation.
