Applications Transportation Due to their energy absorption properties, latex foams are useful for transportation applications, such as in packaging to decrease impact on the shipped product or in vehicle upholstery. While packaging foams may be single-use with low resistance to dynamic fatigue, upholstery tends to benefit from being denser and more resistant to fatigue as it absorbs lower impacts but needs to do so more repeatedly. Furniture Latex foams can be used in items like bedding, upholstery, and pillows for cushioning purposes due to their expressed stress-strain curve when experiencing a load. Soundproofing Due to their containing of air bubbles, latex foams carry some soundproofing properties. In particular, both natural rubber and styrene-butadiene latex foam are found to be good at soundproofing, but styrene-butadiene foams tend to be better for this purpose. Separation of oil and water Oil pollution in water bodies is a major environmental concern. Separating oil and water is helpful both to clean the water and recover the oil. Latex foams are hydrophobic and absorbent, in addition to being resilient and recyclable, and can therefore be used to absorb the oil in water-oil mixtures to separate them. Sports, arts, and recreation Foam latex is used in masks and facial prosthetics to change a person's outward appearance. The Wizard of Oz was one of the first films to make extensive use of foam latex prosthetics in the 1930s. Theatrical latex foam is a specialized latex foam which is softer than commercial latex foam. It can be used in various arts and crafts including puppetry and costumes because of its ability to pick up small details of painting as well as its strength. Miss Piggy, Statler and Waldorf in Jim Henson's The Muppet Show as well as characters in Henson's next production, The Dark Crystal, were some of the first puppets created from latex foams used on a large scale. Artists such as Lordi and GWAR wear costumes that include this material. Latex foam is also widespread in the manufacture of modern soccer goalkeeper gloves. The material has proven to be the most effective way of allowing players to grip the football in wet and dry playing conditions, as well as providing damping properties which help in catching. A variety of treatments are applied to latex foam to produce different types of foam with varying properties to assist performance. Some, for example, are designed to offer a high
