The Magic Behind A Hdpe Pipe S Strength

---

Also known as a high-density polyethylene pipe, the pipe’s material is known for its immense strength, flexibility, long lifespan and its high resistance to corrosion, pressure and chemicals. Thanks to these advantages, it is very suitable for various applications including but not limited to mining, irrigation, waterworks, sewage, gas and fire systems. For companies specializing in gas and water transfers, the pipe is a top choice as a HDPE fittings Malaysia.

HDPE Properties  
The key to the pipe’s superior properties stem from the material itself: polythene. The thermoplastic polymer is so versatile that it is not only made for pipes, but because it remains rigid until very high temperatures, where it reaches its boiling point, it can be molded into a variety of other objects such as plastic bags, toys, containers, cutting boards, prosthetics and even plastic surgery, specifically for skeletal and facial reconstruction.
 
The immense strength of polythene stems from its high strength to density ratio, which when compared to LDPE (low density polyethylene), a weaker sibling, is only slightly higher. But when looked under a microscope, the structure of the HD polythene is linear enough to leave little branching, resulting in a stronger intermolecular force and tensile strength than LDPE.
 
Further adding the appeal of the polythene is that in addition to its durable properties, it is also lightweight enough that heavier materials are replaced in its favor, paving way for sustainable and affordable projects. Another separate factor of its popular appeal is that polythene is easily recyclable, and is identified in recyclable materials by a recycle sign with a number two in the center.
 
HDPE Shortcomings  
The HDPE, however, did not come with a few shortcomings. For starters, it can crack under stress, though still not as easily as LDPE. In other words, HDPE pipes can still leak with this factor in mind. 
 
It also has little to no UV resistance, which upon high exposure, may compromise its highly valued properties through the degradation of strength and resistance. LDPE shares this similar drawback, although likely with more repercussions as it is weak to extreme high or low temperatures. A preventive measure to prevent further UV light exposures to HDPE can be done by placing it indoors or under any roof that shields the sun. Carbon black is also another great alternative, as when used as a resin in the molding of polythene objects like water tanks, it acts as an absorber of UV light. As a result, the absorbed light is then turned to heat and dissipates throughout the object. If there is a worry about rising temperatures, luck is on the side. By the time the temperature rises, the sun is already setting and it cools down enough to not negatively affect the polythene object, even if the color is different as a result of the long exposure.
 
Besides, the polythene also harbors a higher risk of mould shrinking, a phenomenon where the volume of a plastic decreases as it gradually becomes cooler and solidifies. This will render itself useless to create bigger objects, thus it is likely that while they are created, the mould remains hot in higher temperatures after the polythene reaches its boiling point.
