After extensive analysis using a series of testing regimes including HPLC and OIT, the Hubron technical team were able to achieve a bespoke grade of Hubron.additive. This allowed the European based irrigation pipe manufacturer to consolidate their supply chain with a secondary source of additive black masterbatch that met the specification of the additive masterbatch currently used.

Challenges faced by the customer:

The customer is a plastic manufacturer based in Spain, who required masterbatch solutions for their irrigation pipe products, commonly used within the agricultural industry.

Firstly, the customer required an experienced additive black masterbatch manufacture as over extended periods of time, polymers are susceptible to degradation by exposure to heat and ultraviolet radiation in sunlight. This can cause a reduction in physical properties leading to colour change, embrittlement and potentially failure in service life. Plastics can be greatly enhanced by using additives masterbatches, that act to improve those properties and give superior products.

Furthermore, the customer necessitated an alternative supply of their current additive black masterbatch, as they sought to safeguard their supply chain. They required a masterbatch manufacturer that possessed robust R&D capabilities, capable of producing a supplementary supply of masterbatch that exhibited identical performance to their current product used in the manufacturing process.

Hubron’s solution:

With over 85 years of compounding experience, Hubron international are experts at developing additive masterbatches to suit customer specific requirements for many applications such as slip, antifog, antistatic and flame retardants. Therefore, the Hubron technical team were able to successfully test and analyse the customer’s existing additive black masterbatch and produce a countertype. The samples were analysed using HPLC and OIT.


The analytical technique high performance liquid chromatography was used to separate, identify and quantify individual components of the sample.


The oxidative induction time test is an analytical technique that measures the resistance of a polymer to oxidation. OIT is performed on a differential scanning calorimeter (DSC). The test involves heating a polymer sample, under controlled conditions while exposing to oxygen. The time taken for the oxidation process to begin is recorded as the OIT. The OIT technique provides a precise measure of how long it takes for a polymer to start degrading under controlled conditions. This allows for an estimation of the concentration of antioxidant additives present within polymer.

Hubron worked closely with the DSC manufacturers to ensure test methods across both Hubron’s and the customers technical teams aligned. The new grade samples were passed by the customer and the product was rapidly scaled up.
