POE LG Chem LC175
POE LG Chem LC175
POE LG Chem LC175 is a low‑density ethylene‑1‑butene copolymer. It delivers excellent impact resistance, good flexibility, superior high‑filler compatibility and processing advantages, especially suitable as impact modifier for PP toughening and TPO compounds.
Main Applications
Polymer Modification: Primarily for toughening PP to greatly improve impact strength; applicable for soft & hard TPO compounds. General‑Purpose Thermoplastic Elastomer: Can be used as general‑purpose thermoplastic elastomer. Other Applications: Automotive interior & exterior parts, shoe soles, wire and cable.

Processing Guidelines
- No compounding or vulcanization required; process on standard thermoplastic equipment with good flowability.
- Blending modification: For PP toughening, POE loading ≤20 %. Higher POE content improves impact strength and elongation, while tensile strength, flexural strength and modulus decrease accordingly.
- Additives: Antioxidants, softeners, fillers and colorants may be added as needed. Scraps & runners are recyclable; recommended recycle fraction ≤30 % to minimize property degradation.
