1. Can GP-OPTIFILL be used with recycled polymers?

GP-OPTIFILL can also be used in formulations containing recycled polymers. The optimum dosage depends on the type and quality of the recycled material and should be verified during production trials.

2. Is GP-OPTIFILL suitable for multilayer films?

Yes. GP-OPTIFILL can be incorporated into multilayer film structures depending on the application and required film properties.

3. Can GP-OPTIFILL be used in food packaging?

Suitability for food-contact applications depends on the final formulation and applicable regulations. Please contact our technical team for specific compliance information.

4. Does GP-OPTIFILL require any modification of the production line?

No. In most cases GP-OPTIFILL can be processed using standard equipment without modifications. Processing parameters may require only minor optimisation.

5. How is the optimum dosage selected?

The optimum dosage depends on the polymer type, product design and required mechanical and optical properties. Production trials are recommended to determine the best formulation.

6. Is technical support available?

Yes. Global Polimers provides technical assistance during product selection, dosage optimisation and production trials.

7. Can GP-OPTIFILL help optimise production costs?

Yes. The achievable savings depend on the polymer, formulation, application and production process. Cost-saving potential can be evaluated during industrial trials.

8. Do you provide samples for industrial testing?

Yes. Samples are available for qualified industrial customers interested in evaluating GP-OPTIFILL under production conditions.

9. What is GP-DuraFlex?

GP-DuraFlex is a high-performance polyolefin toughness modifier designed to improve impact resistance, flexibility, elongation at break and overall mechanical performance of plastic products while maintaining stable processing.

10. Which polymers is GP-DuraFlex compatible with?

GP-DuraFlex is compatible with LDPE, LLDPE, HDPE and PP. It can be used with virgin materials, recycled polymers and formulations containing filler masterbatches.

11. What processing technologies is GP-DuraFlex suitable for?

GP-DuraFlex is suitable for a wide range of plastics processing technologies, including: Blown film extrusion Cast film extrusion Pipe extrusion Sheet extrusion Profile extrusion Injection moulding Blow moulding

12. What properties does GP-DuraFlex improve?

GP-DuraFlex helps improve: Impact resistance Toughness Flexibility Elongation at break Tensile strength Process stability

13. Can GP-DuraFlex be used with recycled materials?

Yes. GP-DuraFlex performs very well in formulations containing recycled polymers. It helps compensate for the loss of mechanical properties while maintaining stable processing.

14. Does GP-DuraFlex affect processing?

No. GP-DuraFlex is designed to improve mechanical performance without compromising process stability.

15. Can GP-DuraFlex be used together with filler masterbatches?

Yes. GP-DuraFlex is compatible with most polyolefin formulations containing filler masterbatches and can be incorporated directly into existing production processes.

16. What is the recommended dosage?

The typical recommended dosage is between 1% and 3%, depending on the polymer, application and required performance.

17. Can GP-DuraFlex help reduce production costs?

Yes. GP-DuraFlex helps optimise formulations, improve product quality, reduce reject rates and increase the use of recycled materials, contributing to lower production costs.

18. Which industries can benefit from GP-DuraFlex?

GP-DuraFlex is suitable for manufacturers of: Flexible packaging Rigid packaging Injection moulded products Pipes and fittings Sheets and profiles Technical plastic products Products containing recycled polymers

19. Is GP-DuraFlex suitable for food-contact applications?

Food-contact suitability depends on the final formulation and applicable regulations. Please contact our technical team for application-specific information.

20. Can GP-DuraFlex be tested before commercial production?

Yes. We recommend production trials to determine the optimum dosage and evaluate performance under your processing conditions.

21. Does GP-DuraFlex require changes to existing equipment?

No. GP-DuraFlex is designed for use with standard plastics processing equipment and normally does not require equipment modifications.
