Compatibilization of virgin and recycled polyolefin compounds

Polyolefins loaded with minerals fillers, glass fibers, natural fibers, additives are compatibilized by the famous SK Orevac® reactive polyolefins with very high concentration of grafted maleic anhydride. Grades are available for use in (L)LDPE, HDPE, PP compound.


The same additives can also be used to upgrade polyolefin regrinds and they find today a new crucial relevance in view of new laws on mandatory and increasing content of recycled polymers in plastic packaging, which poses challenging issues in terms of compatibilization of polyolefins with polar polymers (EVOH, PA, PET, biopolymers).

Case Study

Compatibilization of HDPE with regrind from recycled barrier food packaging

Opportunity: Customer reprocess (HD)PE regrind, especially for application on hard or stiff end products such as tubes and pipes. Their sources are usually contaminated by multi-layer food packaging, i.e. with PA, EVOH, PET. He was seeking to homogenize his regrinds and improve mechanical properties, without softening the material.

Ambra Impact™ are a powerful and universal additive to increase homogenization and impact properties of recycled compounds.

Case Study

One PA + GF tough story

Opportunity: Customer needed to compatibilize a PA regrind with a near-to-prime glass fiber. Furthermore, he needed to increase his notched and unnotched impact resistance at room tempertaure. And finally, price had to be kept as low as possible, or he would have run out of business.


Ambra Impact PB, versatile universal low-cost impact modifiers for recycled polyesters

During recycling, our customers need to reprocess and ennoble various types of regrinds, often harshly degraded and polluted with other polymers, mineral charges, additives, requiring universal compatibilizers and impact modifiers at the lowest possible price.

Recyled polyesters blends with polyolefins are very common – e.g. PET packaging regrinds polluted with polyolefin caps.

Reactive Ambra Impact PB improves mechanical properties and impact already at relatively low dosage, allowing very reasonable final costs for the reprocessed formulations. It is an elective choice for the recycling of PET, PBT, PLA and other polyesters blended with any other polymers (PE, PP, PS, ABS, PC, PPS, POM).

From nightmare to dream, from dream to reality.
