Wood is the oldest material used by humans for construction after stone. Despite its complex chemical nature, wood has excellent properties which lend themselves to human use. read more
A chemical property is a characteristic that can only be seen when the material changes and a new material is formed. Examples of chemical properties are ability to burn, ability to rust and ability to sour. So a chemical property of wood is its ability to burn. When it burns, it gets hot and changes to ash. read more
Following properties of wood makes it good for use in construction. Specific Gravity (SG): Generally, specific gravity (SG) and the major strength properties of wood are directly related. SG for the major, usually used structural species ranges from roughly 0.30 to 0.90. read more
The chemical properties of plastics depend on the type of polymer used during the manufacturing process. Every polymer has very distinct characteristics but most share a few similar characteristics. For instance, most polymers are very resistant to chemicals contained in solvents such as cleaning fluids. read more
