Energy Absorption Properties

This energy loss and consequent heat build-up occurs in all elastomers to some degree or other, and since these are poor conductors of heat the

PE crosslinked foams offer higher stability and mechanical strength, better insulation characteristics, and improved energy-absorption properties. Most of these foams can be thermoformed, embossed, printed, laminated, or punched, using conventional equipment.

Examples of composite materials and hybrid structures having unique cut resistance and energy absorption properties in protective clothing and personal protection equipment (helmet, knee protection panel, gloves, protection curtains, protection tent and shield, etc.) are discussed in this section. 

Growth wiU also come from expandable PP foam with excellent energy absorption properties (see the chapter, Modelling of the compression behavior of pol)q3ropylene foams in this book) which will allow new, innovative designs in bumper systems and monomaterial interior trim solutions, in combination with improved TPO foils for door trim and instrument panels.
