Britax is the patent holder for over 180 United States granted patents. [ 1 ] [ 2 ] The Isofix (known as LATCH in the US) system was developed jointly by child safety seat maker Britax-Römer and Volkswagen , with the first compatible products released in 1997. [ 3 ]
Foam rubber yoga mat. 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 ...
The company was founded as Fagerdala World Foams in 1964 by father and son, Alf and Dag Landvik. [citation needed]The company’s initial products were Polyurethane mattresses and cushions, before expanding into other foam applications.
A foaming agent is a material such as a surfactant or a blowing agent that facilitates the formation of foam.A surfactant, when present in small amounts, reduces surface tension of a liquid (reduces the work needed to create the foam) or increases its colloidal stability by inhibiting coalescence of bubbles.

Polyurethane synthesis, wherein the urethane groups −NH−(C=O)−O− link the molecular units A kitchen sponge made of polyurethane foam . Polyurethane (/ ˌ p ɒ l i ˈ jʊər ə ˌ θ eɪ n,-j ʊəˈr ɛ θ eɪ n /; [1] often abbreviated PUR and PU) refers to a class of polymers composed of organic units joined by carbamate (urethane) links.
Syntactic foam, shown by scanning electron microscopy, consisting of glass microspheres within a matrix of epoxy resin. Syntactic foams are composite materials synthesized by filling a metal, polymer, [1] cementitious or ceramic matrix with hollow spheres called microballoons [2] or cenospheres or non-hollow spheres (e.g. perlite) as aggregates.
Order and disorder of bubbles in a surface foam One scale is the bubble: material foams are typically disordered and have a variety of bubble sizes. [ citation needed ] At larger sizes, the study of idealized foams is closely linked to the mathematical problems of minimal surfaces and three-dimensional tessellations , also called honeycombs .
Non-printing characters or formatting marks are characters for content designing in word processors, which are not displayed at printing. It is also possible to customize their display on the monitor. The most common non-printable characters in word processors are pilcrow, space, non-breaking space, tab character etc. [1] [2]
