Resam-PPS™

Resam-PPS™ is a proprietary (foamable) high melt strength polypropylene system designed by Amcor to produce extremely tough, light weight, and cost-effective polypropylene substrates.

Resam-PPS™ has produced foam with density as low as 1 lb/ft3, with only the addition of physical expanding agents. Foams made with 100% Resam-PPS™ are flat and closed cell, with a fine cell structure and smooth surfaces.  Due to its high melting point and excellent thermal stability, Resam-PPS™ can be heat welded or co-extruded with most other polymers. Furthermore, Resam-PPS™ can be laminated to other substrates (such as metals, plastics, fiberglass, woven fabrics, non-woven fabrics, and Cosmolite) using polymer-based or water-based adhesives, when skived or corona treated.

Applications:  Resam-PPS™ allows for a range of innovative applications where stiffness and compression strength are required. When foamed at densities from 4 to 16 lbs/ft3, Resam-PPS™ may be used to produce structural foam sheet, plank, and profiles as a replacement for wood-based and other structural products. It can also be lightly foamed or used to add melt strength to thermoformed sheet.

Resam-HF

Resam-HF is a proprietary ethylene-styrene based compound designed to produce low density foam with excellent thermal and sound insulation properties.  This product enables the production of hard, light-weight foam on conventional polyethylene foam extruders.  The foam is dimensionally stable in changing temperature environments.  Resam-HF should be processed at 100% with the addition of gas only.  However, conventional nucleators may be added to achieve desired cell size.

Applications: Insulation, packaging, floor underlayment (and as a substitute for other polystyrene applications)

Resam-HFx8

Resam-HFx8 is a proprietary polyolefin based compound designed to produce low density foam with excellent insulation properties.  This product enables the production of very hard, light-weight foam on conventional polyethylene foam extruders.  The foam is extremely ridged and dimensionally stable.  Resam-HFx8 should be processed at 100% with the addition of gas only.  However, conventional nucleators may be added to achieve desired cell size.

Applications: Plastic furniture and decorative insulation
