CAF or caf may refer to:
Arlindo Gomes Semedo (born 17 November 1977), known as Cafú, is a Cape Verdean professional footballer who plays for S.C. Freamunde as a forward.
After playing in his country of birth for Belenenses and Boavista, amassing Primeira Liga totals of 153 games and 17 goals over the course of seven seasons, he went on to have a brief spell in Germany with Freiburg.
Already in his 30's Cafú moved to Cyprus, where he remained for five years in representation of several teams. Internationally, he played for Cape Verde.
Cafú was born in Lisbon, Portugal. During his early career he played for Almada AC, Amora FC, C.F. Os Belenenses – with which he made his Primeira Liga debuts in the 1999–2000 season – and Boavista FC, appearing in six games in the Porto team's quarterfinal run in the UEFA Cup in 2002–03 but starting rarely during his three-and-a-half-year spell with the club.
In January 2006, Cafú moved to Sportfreunde Siegen in Germany's second division, his five league goals not being enough to avoid relegation (as last). He subsequently stayed in the category and joined SC Freiburg, where he would appear sparingly in one-and-a-half-years.

Poly(methyl methacrylate) (PMMA), also known as acrylic or acrylic glass as well as by the trade names Plexiglas, Acrylite, Lucite, and Perspex among several others (see below), is a transparent thermoplastic often used in sheet form as a lightweight or shatter-resistant alternative to glass. The same material can be utilised as a casting resin, in inks and coatings, and has many other uses.
Although not a type of familiar silica-based glass, the substance, like many thermoplastics, is often technically classified as a type of glass (in that it is a non-crystalline vitreous substance) hence its occasional historic designation as acrylic "glass". Chemically, it is the synthetic polymer of methyl methacrylate. The material was developed in 1928 in several different laboratories by many chemists such as William Chalmers, Otto Röhm and Walter Bauer and was first brought to market in 1933 by the Rohm and Haas Company under the trademark Plexiglas.
PMMA is an economical alternative to polycarbonate (PC) when extreme strength is not necessary. Additionally, PMMA does not contain the potentially harmful bisphenol-A subunits found in polycarbonate. It is often preferred because of its moderate properties, easy handling and processing, and low cost. Non-modified PMMA behaves in a brittle manner when under load, especially under an impact force, and is more prone to scratching than conventional inorganic glass, but modified PMMA is sometimes able to achieve high scratch and impact resistance.
Poly(hydridocarbyne) (PHC) is one of a class of carbon-based random network polymers primarily composed of tetrahedrally hybridized carbon atoms, each having one hydride substituent, exhibiting the generic formula [HC]n. PHC is made from bromoform, a liquid halocarbon that is commercially manufactured from methane. At room temperature, poly(hydridocarbyne) is a dark brown powder. It can be easily dissolved in a number of solvents (tetrahydrofuran, ether, toluene etc.), forming a colloidal suspension that is clear and non-viscous, which may then be deposited as a film or coating on various substrates. Upon thermolysis in argon at atmospheric pressure and temperatures of 110 °C to 1000 °C, decomposition of poly(hydridocarbyne) results in hexagonal diamond (Lonsdaleite).
More recently poly(hydridocarbyne) has been synthesized by a much simpler method using electrolysis of chloroform (May 2008) and hexachloroethane (June 2009).
The novelty of PHC (and its related polymer poly(methylsilyne)) is that the polymer may be readily fabricated into various forms (e.g. films, fibers, plates) and then thermolized into a final hexagonal diamond ceramic.
Poly Property Group Co., Limited (SEHK: 119), is a property developer in China, with its major businesses include property development, investment and management. It mainly develops mid to high-end residential and commercial properties in the cities along Yangtze River Delta and Pearl River Delta as well as the second-tier provincial capitals.

Poly (Hong Kong) Investments was established in 1973, originally a shipping company called Haikang Investment Limited. In 1993, China Poly Group Corporation acquired 55% stake in the company and converted its business from shipping to conglomerate. In 2005, Haiking Investment was renamed to Poly (Hong Kong) Investments.
