To improve processing and UV resistance of a drip irrigation pipe, the masterbatch formulation needs to combine an optimised carrier and anti-oxidant system with a high-quality carbon black pigment. Colloids’ special masterbatch allows for cost-effective drip irrigation systems that are expected to last a minimum of two growing seasons in a temperate and tropical climate.
Colloids have designed products that promote the best growth conditions, with polymer grades used in a wide range of polyethylenes, EVA, PLA and PHA, as well as meeting the increasing demand for biodegradable mulch films.
Often located in the harshest of environments of extreme temperatures, UV radiation, oxygen and ozone attack, the polymers used must perform faultlessly. This requires careful choice and formulation of pigments and additives to protect the polymers.
