Polyethylene is the world's most widely used thermoplastic and is made by the polymerization of ethylene. Polyethylene is often classified by its density, because greater density corresponds with greater material rigidity. The world�¢??s largest volume polyethylene is high density polyethylene (HDPE), which has a relatively high degree of tensile strength. Plastic containers represent the most common household use of high-density polyethylene. At the opposite end of the spectrum is low density polyethylene (LDPE), which was the first type of polyethylene to be developed. Flexible packaging represents the most common household use of low-density polyethylene. Both high- density polyethylene and low-density polyethylene are also commonly used for moulding applications. Linear low-density polyethylene (LLDPE) can usually be manufactured at a slightly lower cost than low density polyethylene and has similar basic properties. While low-density polyethylene and linear low-density polyethylene are to a certain extent substitutable for each other, one may be more suitable than the other for a specific application.

Microsilica (silica fume) is a by-product from silicon metal or ferrosilicon industries, is an amorphous silicon dioxide SiO2. This product reacts chemically with the calcium hydroxide in the cement paste which yields a calcium silicate hydrate gel that significantly enhances strength and durability. The super fine microsilica fills the voids between cement particles creating a very dense, less permeable concrete. White Cement advantages: Sustainability: Solar Reflectance Index (SRI): Floors finished with white or pastel color concrete will have a much higher SRI than floors with gray concrete, therefore they will reflect light better, and generate energy savings for the lifetime of the floors. Reduction of Heat Island effect: By constructing buildings with white concrete roofs or light-colored roof tiles, the Heat Island Effect is reduced from surfaces generating less heat and improved reflectivity. Architectural Concrete: White Portland Cement is ideal for decorative concrete and Architectural Concrete applications, Masonry and Cementitious Building Products. A key advantage of using white cement for these applications is that it provides a base color that can be tinted to custom colors to meet any color spectrum demand.
