Plastiducto S.A. is the first company in Uruguay with more than 50 years of experience in producing low density polyethylene pipes (LDPE). Our products are distinguished by 3 parallel stripes, they are manufactured with the best raw materials and differentiated from others for their excellent quality.
These pipes are extensively used in agriculture and water distrubution nets.
Each use has its own type of pipe recognizable for the colour of the 3 stripes:
3 yellow stripes for general purposes, named LDPE “3 STRIPES”
3 green stripes for agriculture, named “AGRODUCTO”
Manufactured with low density polyethylene (LDPE) virgin.
Operating temperature up to 40º C.
Supplied in coils up to 200 meters.
Additivated with carbon black to protect it from UV rays.
Resists flattening 100%.
Joint system through spigot fittings.

Resistance to the weather elements
Low density polyethylene pipes (“3 Stripes”) are protected against the degradation by ultraviolet rays (UV) due to the addition of carbon black when manufactured. However, it is recommended to bury the pipes, in order to avoid this attack factor.
