FINGERPRINT™ Polyethylene Resins help tubing and tape manufacturers produce some of the finest quality, longest-lasting products in the micro irrigation industry by combining key attributes such as:
- Flexural toughness
- Environmental stress crack resistance (ESCR)
- Burst strength
- Slow crack growth (SCG) resistance
- Impact and puncture resistance
Their excellent strength and durability offers opportunities to develop applications with both long life expectancy and excellent resistance to leaks and cracks – helping to not only reduce water loss but also potentially lower costs.
For example, Dow testing1 shows that FINGERPRINT™ 7520 Medium Density Polyethylene (MDPE) Resin – our next generation bimodal resin for micro irrigation tape – offers significant dart impact resistance2, 3 and improved Elmendorf tear properties.4, 5 In addition to these critical properties, the resin also offers good processability, tensile strength, toughness, ESCR, and SCG resistance.
As an added measure of quality control, all micro irrigation tubing and tape made with FINGERPRINT Resins can be identified by a special tracer element added to every resin.
Combined with the inherent efficiency of micro irrigation, the strong performance and high levels of quality assurance offered by FINGERPRINT Resins support the development of irrigation systems that make responsible water management a serious priority.
