Thermoplastic Elastomer based on Recycled HDPE/Ground Tire Rubber Interfacially Modified with an Elastomer: Effect of Mixing Sequence and Elastomer Type/Content
Bibliographic record
Abstract
The effect of interfacial interaction and processing methods (one-step and two-step) on the structure–property relationships of ternary blends was investigated. The addition of ethylene-vinyl acetate (EVA) and ethylene octene copolymer (POE) resulted in homogeneous structure and greatly improved rubber-like properties of recycled high-density polyethylene (rHDPE) and regenerated tire rubber (RR) blends. Interfacial tension calculations revealed a high tendency of POE to encapsulate rubber particles (complete wetting). The two-step processing contributed to perfect encapsulation of the rubber phase via a soft/thick POE interface resulting in uniform RR particle dispersion, high elongation at break (138.5%), and impact strength (394 J/m) of rHDPE/(RR/POE) (20/80) ternary blend.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
