Bonding study: Armacell component foams

Elastomeric Foam

Elastomeric Component Foam (ECF) products are high-performance foam formulations that meet stringent physical and chemical property requirements. Armacell's ECF brands include ArmaSound®, ArmaSport®, EnsoLine®, EnsoLite®, and Monarch®. It offers hundreds of expanded rubber products used extensively in industrial, transportation, building/construction and sport/recreational applications. Sixty years of foam innovation enables us to design optimized cell structures and densities for specific physical properties — custom engineered to customer needs.

Polyolefin Foam

Polyolefin Component Foams (PCF) are made from thermoplastic polymers. Armacell's PCF brands include OleCell® and OleTex®. The company makes chemically cross-linked polyethylene in rolls or blocks called “buns” in formulations that vary from soft and flexible to stronger, stiffer specifications. Non-cross-linked polyethylene can be extruded into customizable profile shapes and can be used for thermoforming applications.

Armacell component foams and Avery Dennison adhesive sample preparation

Avery Dennison FT 8299 was backed with a 2 mil PET film and trimmed to a one-inch width. Two sample sets were laminated to Armacell Component Foams.

Armacell component foams and Avery Dennison adhesive sample testing

Foam bonding is affected by the foam's base polymer, thickness, and cell type. Adhesion to foam is impacted by factors such as: adhesive mass, pressure, compression, lamination speed and temperature. All samples of FT 8299 were tested at 180° Peel Adhesion at 12 in/min. It was determined by this study that heat lamination is beneficial (220˚F).
