Polyolefin foams offer fire resistance in cars

Plastics and foam materials producer Sekisui Alveo has developed a cross-linked polyolefin foam for engine encapsulation and acoustic damping that offers integral fire resistance without the need to add expensive fire retardant chemicals.

Alveolen NP(A) FRV has been tested at the group's laboratories in Switzerland and meets important flammability and general fire behaviour tests, the company says.

Instead of burning and generating a flame, the material tends to melt when a Bunsen burner plame is applied directly to it.
