GPS HD 40 Mil's Superior Strength
Intro: When it comes to high-density polyethylene (HDPE) geomembranes, the 40 mil thickness stands out as the most common choice. In this comprehensive guide, we will explore the remarkable features, benefits, and applications of GPS HD 40 mil, a smooth and high-quality HDPE geomembrane designed to tackle various challenges, including root barriers for invasive plants like bamboo.
The Power of GPS HD 40 Mil:
GPS HD 40 mil is crafted from specially formulated, virgin polyethylene resin, making it ideal for flexible geomembrane applications. It boasts an impressive composition of approximately 97.5% polyethylene, 2.5% carbon black, and trace amounts of antioxidants and heat stabilizers—without any other additives, fillers, or extenders. Let's delve into why this geomembrane is a preferred choice.
Exceptional Chemical Resistance: One of the standout qualities of GPS HD 40 mil is its outstanding chemical resistance. It can withstand a wide range of chemical substances, making it suitable for applications where exposure to various liquids is a concern. Some of the chemicals that 40 Mil HDPE is resistant to include acids, bases, salts, and many organic solvents. It also demonstrates resistance to environmental factors like UV radiation, ensuring durability even in exposed conditions. This chemical resistance makes it suitable for applications where protection against hazardous substances and environmental factors is crucial, such as in landfill liners, containment systems, and root barriers. Whether you're dealing with industrial chemicals or agricultural solutions, this liner has you covered.
Combatting Stress Cracks: Stress cracks can be a significant concern for geomembranes, but not for GPS HD 40 mil. Its exceptional stress crack resistance ensures long-term durability and reliability. Even under challenging conditions, this geomembrane maintains its integrity, offering peace of mind to users.
What is a Stress Crack? A stress crack is a type of crack or fracture that occurs in a material, such as plastic or glass, due to the combined effects of mechanical stress and exposure to environmental factors. These cracks typically initiate at points of weakness or imperfections in the material and gradually propagate over time, often compromising the material's structural integrity. Stress cracks can result from factors like temperature fluctuations, UV radiation, or tension, and they are a common concern in various industries, including construction and engineering.
Lowest Permeability: When it comes to preventing the passage of liquids and gases, GPS HD 40 mil excels with its remarkably low permeability. This feature is particularly valuable in applications where containment and isolation are vital, such as pond liners or landfills.
Proven Performance: History speaks volumes, and GPS HD 40 mil boasts a track record of proven performance. It meets or exceeds the stringent requirements of GRI GM13, providing assurance of its quality and reliability. This geomembrane has been put to the test and has consistently delivered outstanding results.
How Long has HDPE been Around?
High-Density Polyethylene (HDPE) was discovered in the 1930s by two British chemists, Eric Fawcett and Reginald Gibson, working for the Imperial Chemical Industries (ICI). The discovery of HDPE marked a significant advancement in the field of plastics, as it offered improved strength and other desirable characteristics compared to low-density polyethylene (LDPE). HDPE has since become one of the most widely used and versatile plastics, finding applications in various industries, including packaging, construction, and more.
Dimensional Stability and Thermal Resistance: Dimensional stability refers to a material's ability to maintain its original shape and size when subjected to external influences like temperature changes, moisture, or mechanical stress. In simpler terms, a dimensionally stable material will not warp, shrink, or deform significantly when exposed to such factors, ensuring its reliability and consistency in various applications.
GPS HD 40 mil exhibits impressive dimensional stability, with a deviation of ±2% when tested according to ASTM D 1204. Additionally, it demonstrates excellent thermal aging characteristics, ensuring its longevity even in demanding environments.
Tensile Strength and Elongation: Tensile strength measures a material's ability to withstand stretching or pulling forces without breaking, indicating its durability and load-bearing capacity. Elongation, on the other hand, indicates how much a material can stretch before it reaches its breaking point, providing insight into its flexibility and resilience under stress, which are crucial factors in assessing a material's suitability for various applications.
This geomembrane's tensile properties, tested according to ASTM D 6693, Type IV, reveal its strength and flexibility. With a strength at break of 152 lb/in-width (27 N/mm) and strength at yield of 84 lb/in-width (15 N/mm), it can handle substantial loads. Its elongation at break reaches 700%, while elongation at yield stands at 12%.
Root Barrier Application: GPS HD 40 mil is widely recognized for its role as a root barrier, effectively halting the growth of invasive plant roots like bamboo. Its robust construction ensures that it can withstand the pressure exerted by aggressive root systems, making it a reliable choice for landscaping and horticultural projects.
Conclusion: In conclusion, GPS HD 40 mil HDPE geomembrane is a versatile and dependable solution for a wide range of applications. Its exceptional chemical resistance, stress crack resistance, low permeability, and proven performance make it the top choice for many industries. Whether you need to contain liquids, protect against root intrusion, or ensure long-term durability, GPS HD 40 mil delivers unmatched quality and reliability. Consider this geomembrane for your next project, where strength, resilience, and performance matter most.
