This polyethylene resin is designed specifically for flexible geomembrane applications. It contains approximately 97.5% polyethylene, 2.5% carbon black and trace amounts of antioxidants and heat stabilizers; no other additives, fillers or extenders are used. **GPS HD** has outstanding chemical resistance, mechanical properties, environmental stress crack resistance, dimensional stability and thermal aging characteristics. **GPS HD** has excellent resistance to UV radiation and is suitable for exposed conditions. These product specifications meet or exceed **GRI GM13**. This product is used as a root barrier to stop bamboo roots and other invasive plant roots.   **40 mil HDPE The Most Common HDPE liner thickness due to its balence of cost, strength and permability.** - **Excellent chemical resistance** - **Outstanding stress crack resistance** - **Lowest permeability** - **History of proven performance** - **Meet or exceed all aspects of GRI GM 13** - **All GSE geomembranes have dimensional stability of ±2% when tested with ASTM D 1204 and LTB of <-77° C when tested with ASTM D 746.** - **Tensile Properties (each direction) ASTM D 6693, Type IV 20,000 lb** - **Strength at Break, lb/in-width (N/mm): 152 (27)** - **Strength at Yield, lb/in-width (N/mm): 84 (15)** - **Elongation at Break, %: 700** - **Elongation at Yield, %: 12** - **Tear Resistance, lb (N)- ASTM D 1004- 45,000 lb-  28 (125)** ##         When do you use HDPE versus LLDPE?  [![HDPE LLDPE APPLICATION CHART](https://no-cache.hubspot.com/cta/default/32796/df561b09-6aed-436c-b1b7-94920c0bcc91.png)](https://cta-redirect.hubspot.com/cta/redirect/32796/df561b09-6aed-436c-b1b7-94920c0bcc91)   ## [** 40 mil HDPE Applications Click here.**](https://www.globalplasticsheeting.com/40-mil-hdpe-liner-applications?hsLang=en-us) **  [![Tap For Pricing & Info (619) 448-4439](https://no-cache.hubspot.com/cta/default/32796/919f3d0d-5f01-4efc-b326-229bacaacbbf.png)](https://cta-redirect.hubspot.com/cta/redirect/32796/919f3d0d-5f01-4efc-b326-229bacaacbbf)**   ## Have Root Barrier or other HD Question?
