  2. Rubber toughening - Wikipedia

    en.wikipedia.org/wiki/Rubber_toughening

    Rubber toughening is a process in which rubber nanoparticles are interspersed within a polymer matrix to increase the mechanical robustness, or toughness, of the material.By "toughening" a polymer it is meant that the ability of the polymeric substance to absorb energy and plastically deform without fracture is increased.

  3. Toughening - Wikipedia

    en.wikipedia.org/wiki/Toughening

    In materials science, toughening refers to the process of making a material more resistant to the propagation of cracks. When a crack propagates, the associated irreversible work in different materials classes is different. Thus, the most effective toughening mechanisms differ among different materials classes.

  4. Foam rubber - Wikipedia

    en.wikipedia.org/wiki/Foam_rubber

    Foam rubber (also known as cellular rubber, sponge rubber, or expanded rubber) is rubber that has been made with a foaming agent so that its structure is an air-filled matrix. Commercial foam rubber is generally made of synthetic rubber, natural latex, or polyurethane. Latex foam rubber, used in mattresses, is well known for its endurance.

  5. Toughness - Wikipedia

    en.wikipedia.org/wiki/Toughness

    Toughness is related to the area under the stress–strain curve.In order to be tough, a material must be both strong and ductile. For example, brittle materials (like ceramics) that are strong but with limited ductility are not tough; conversely, very ductile materials with low strengths are also not tough.

  6. Membrane roofing - Wikipedia

    en.wikipedia.org/wiki/Membrane_roofing

    Membrane roofing is a type of roofing system for buildings, RV's, Ponds and in some cases tanks. It is used to create a watertight covering to protect the interior of a building. Membrane roofs are most commonly made from synthetic rubber, thermoplastic (PVC or similar material), or modified bitumen. Membrane roofs are most commonly used in ...

  7. Poly(methyl methacrylate) - Wikipedia

    en.wikipedia.org/wiki/Poly(methyl_methacrylate)

    PMMA technology is utilized in roofing and waterproofing applications. By incorporating a polyester fleece sandwiched between two layers of catalyst-activated PMMA resin, a fully reinforced liquid membrane is created in situ. PMMA is a widely used material to create deal toys and financial tombstones.

  8. Crazing - Wikipedia

    en.wikipedia.org/wiki/Crazing

    [8] [9] In thermosetting polymers crazing is less frequently observed because of the inability of the crosslinked molecules to undergo significant molecular stretching and disentanglement, [10] [11] if crazing does occur, it is often due to the interaction with second-phase particles incorporated as a toughening mechanism.
