(lastics
(lastics !ave been used in furniture since it was proven t!at t!ese materials are strong, lig!tweig!t, versatile in design, reduce costs and can be decorated in all patterns an d varieties of color. #!ermal and lig!t stabili)ers can play a key role in keeping keeping t!e aest!etic appeal of furniture as well as preventing degradation during manufacture.#!e term *plastics* covers a range of synt!etic or semi synt!e synt!etic tic organi organic c conden condensat sation ion or polym polymeri eri)at )ation ion produ products cts t!at t!at can be molded molded or e&truded into ob+ects, lms, or bers. #!eir name is derived from t!e fact t!at in t!eir semiliu semiliuid id state t!ey are malleable, malleable, or !ave t!e propert property y of plasticity plasticity..

-etals
-etal is used as structural framework for larger buildings suc! as skyscrapers, or as an e&ternal surface covering. #!ere are many types of metals used for building. It
reuires a great deal of !uman labor to produce metal, especially in t!e large amounts needed for t!e building industries. Corrosion is metals prime enemy w!en it comes to longevity.
•
Steel
Steel is a metal alloy w!ose ma+or component is iron, and is t!e usual c!oice for metal structural building materials. It is strong, /e&ible, and if rened well and0or treated lasts a long time.
•
Copper
Copper is a valued building material because of its advantageous properties. Copper is incorporated into roong, /as!ing, gutters, downspouts, domes, spires, vaults, wall cladding, building e&pansion +oints, and indoor design elements.
•
1t!er metals used include c!rome, gold, silver, and titanium. #itanium can be used for structural purposes, but it is muc! more e&pensive t!an steel. C!rome, gold, and silver are used as decoration, because t!ese materials are e&pensive and lack structural ualities suc! as tensile strengt! or !ardness.
•
Concrete
Concrete is a composite building material made from t!e combination of aggregate and a binder suc! as cement. Concrete !as been t!e predominant building material in t!e modern age due to its longevity, formability, and ease of transport. 2fter mi&ing, t!e cement !ydrates and eventually !ardens into a stonelike material. 3!en used in t!e generic sense, t!is is t!e material referred to by t!e term *concrete*.

4lass
4lass is generally made from mi&tures of sand and silicates, in a very !ot re stove called a kiln, and is very brittle. 2dditives are often included t!e mi&ture used to produce glass wit! s!ades of colors or various c!aracteristics. #!e use of glass in arc!itectural buildings !as become very popular in t!e modern culture.

(ipes 5 Fittings
#raditional materials used in manufacturing pipes are being increasingly replaced by plastics, w!ic! are lig!ter weig!t, less e&pensive and easier to use. "epending on t!eir nal application, plastic pipes reuire di6erent levels of processing, t!ermal and lig!t stability.
Fittings are critical for piping systems to ensure long lasting secure +ointing systems and a maintenance free service life.

7oong -embranes
(lastic roong membranes are widely used for waterproong systems in domestic and industrial /at roof markets. (lastic 7oong -embranes s!ould contain a process stabili)er to protect t!e membrane during e&trusion or calendering, and a 89 stabili)er and a t!ermal stabili)er to protect t!e membrane from !eat and lig!t degradation during t!e product lifetime. 89 stabili)ers t!at provide t!e most protection are combinations of low molecular weig!t and !ig! molecular weig!t H2:S.

Sealing proles 5 Sealants
Sealants are reuired to seal and ad!ere to t!e appropriate mating surfaces over a wide range of temperatures, environmental stress and +oint movement conditions. #o ensure t!at t!e p!ysical properties of sealants are maintained, it is necessary to prevent or retard t!e degradation of t!e sealant.
