LRPu

LRPu or low-resilience polyurethane is a material distinguished by an "ability to slowly return to its original shape".[1]

The resulting impact resistance results in LRPu being used in soft laptop sleeves[1] and other lightweight cases for portable electronic equipment, as an alternative to the softer neoprene.
