PolyPhase is currently being evaluated for conventional polyethylene (PE) and polypropylene (PP) applications. Suitability depends on the resin, formulation, manufacturing process and finished-product requirements.

A typical starting formulation may use around 1% masterbatch. The final addition rate depends on the polymer, product design, required service life and intended application.

PolyPhase is intended to be evaluated within existing PE and PP processing systems. The manufacturer’s normal extrusion or converting process can be used as the starting point, with processing compatibility confirmed during a production trial.

This needs to be confirmed for each application. Relevant properties such as tensile strength, elongation, tear resistance, puncture performance, sealing and other product-specific requirements should be checked during the trial before commercial use.

The formulation can be developed around factors such as polymer type, product thickness, required service life, climate and local environmental conditions. There is no single degradation timeline that applies to every product or location.

Under suitable environmental conditions, the technology is intended to promote polymer-chain scission and molecular-weight reduction. This produces shorter polymer chains that can become more accessible to subsequent biological degradation.

Molecular-weight reduction is not the same as percentage biodegradation.

No. PolyPhase is being developed as a functional masterbatch for conventional PE and PP. The existing polyolefin remains the main material rather than being replaced by a completely different biodegradable resin system.

Yes. The underlying technology has undergone third-party laboratory testing and agricultural field evaluation. Results available so far include measurable biodegradation under defined laboratory conditions and substantial molecular-weight reduction in selected field trials.

Results are specific to the formulation tested, test method and environmental conditions.

Testing has been carried out on selected samples, but PolyPhase is not currently being marketed with a universal “zero microplastics” claim. Any such claim for a finished product should be supported by testing appropriate to the specific formulation and intended environment.

No. Regulatory classification, testing and certification requirements can vary by country and application. These requirements should be reviewed as part of the local evaluation process before commercial deployment.

Yes. The intended approach is to begin with a manufacturer evaluation and production trial. Finished-product performance can then be assessed before moving to local field validation or wider commercial supply.

Helpful starting information includes the polymer type and grade, current product formulation, manufacturing process, product thickness or weight, required service life, mechanical-performance requirements, intended end use and target market.

For agricultural applications, crop type, local climate and expected field life are also useful.
