Plastic Pipe lengths manufactured in Australia by extruding HDPE material.. Plastic pipe is a tubular section, or hollow cylinder, made of plastic.It is usually, but not necessarily, of circular cross-section, used mainly to convey substances which can flow—liquids and gases (fluids), slurries, powders and masses of small solids.
HDPE pipe is a type of flexible plastic pipe used to transfer fluids and gases. It is often employed for replacing aging concrete or steel main pipelines . Constructed from the thermoplastic HDPE (high-density polyethylene ), it has low permeability and robust molecular bonding, making it suitable for high-pressure pipelines .
HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE.

Medium-density polyethylene (MDPE) is a type of polyethylene defined by a density range of 0.926–0.940 g/cm 3. [1] It is less dense than HDPE, which is more common. MDPE can be produced by chromium/silica catalysts, Ziegler-Natta catalysts or metallocene catalysts. MDPE has good shock and drop resistance properties.

Internet user growth is around 2.8% year-on-year. 97.2% of users rely on their mobile phones as one of the (or the only) ways they access the internet. In January 2024, there were 86.98 million internet users in the Philippines, with an internet penetration rate of 73.6 percent of the total population. [27]
The economy of the Philippines is an emerging market, and considered as a newly industrialized country in the Asia-Pacific region. [31] In 2024, the Philippine economy is estimated to be at ₱26.55 trillion ($471.5 billion), making it the world's 32nd largest by nominal GDP and 13th largest in Asia according to the International Monetary Fund .
