Abstract
Described are implements made from a durable HIPE foam material. The HIPE foam has a Toughness Index of at least 75 where the Toughness Index relates properties related to durability (e.g., density, tan[&dgr;] height, glass transition temperature, and abrasion resistance) into a single composite descriptor thereof. Exemplary implements include: wipes, toys, stamps, art media, targets, food preparation implements, plant care implements, and medical wraps.
