Product Overview & Key Features
LC170 POE is manufactured by LG Chem and belongs to the Lucene™ series of polyolefin elastomers (POE). LC170 is an ethylene-octene copolymer thermoplastic elastomer with a density of 0.870 g/cm³, featuring exceptional low-temperature toughness, high elongation, and good tear resistance. It possesses a low glass transition temperature, allowing it to maintain elasticity even in cold environments. With a melt index of 1.1 g/10min and a Mooney viscosity of 23 MU, this grade exhibits excellent compatibility with polyolefin substrates such as PP and PE, and is commonly used as a toughening modifier for polyolefin systems. The raw material is compatible with mainstream thermoplastic processing technologies including twin-screw compounding granulation, injection molding, and extrusion.
- Ultra-low glass transition temperature with stable low-temperature impact performance, making it ideal for modifying products used in low-temperature working conditions;
- Super-high elongation at break with outstanding material ductility, improving the anti-cracking capability of substrates;
- Good compatibility with PP, HDPE, and LDPE, enabling uniform dispersion without the need for additional compatibilizers;
- Balanced melt fluidity and a broad processing window, adapting well to continuous compounding and pelletizing production lines;
- Hydrolysis-resistant and resistant to non-polar chemicals, preventing stress cracking during long-term use;
- Low Mooney viscosity, ensuring uniform dispersion during mixing and reducing processing energy consumption for modified formulations.

Applications & Processing Guidelines
Recommended Applications
- Polypropylene Modification: Low-temperature toughening masterbatches for homopolymer PP and copolymer PP, automotive modified PP, and structural appliance component toughening to enhance low-temperature notched impact strength;
- Polyolefin Composite Systems: Toughness and tear resistance modification for HDPE/LLDPE films, as well as elastic composite film base materials;
- Flexible Modified Parts: TPO composite soft skins, shock-absorbing plastic components, and everyday elastic injection-molded items;
- Recycled Plastic Modification: Toughness and compatibility modification for recycled PP and PE to upgrade the mechanical performance of recyclates;
- Wire & Cable Accessories: Toughening additives for low-smoke zero-halogen (LSZH) systems to improve the toughness of filler-loaded matrixes.
Processing Guidelines
- POE raw material has extremely low water absorption and can be fed directly under standard storage conditions; if exposed to high humidity for an extended period, drying at 70~80 ℃ for 2 hours is recommended to remove surface-adsorbed moisture.
- Recommended twin-screw processing temperature range is 180~220 ℃; with a melt index of 1.1 g/10min, LC170 belongs to medium-low fluidity grades, so screw speed should not be excessively high to prevent molecular chain degradation caused by over-shearing. When used for PP toughening modification, adjust the addition ratio progressively based on targeted impact requirements, and prioritize small-scale trial runs for validation.
Logistics, Packaging & Compliance
- LG Chem Lucene™ LC170 POE is packed in standard 25 kg moisture-proof composite packaging bags. The product consists of solid plastic pellets and is classified as a non-hazardous chemical, exempt from dangerous goods transportation controls. TaiKuo New Materials maintains safety stock, with domestic spot order delivery cycles taking 5~8 business days and export orders taking 10~16 business days, subject to the agreed trade terms. This product can be co-loaded and shipped in mixed containers with other non-hazardous thermoplastic resins, facilitating client consolidation of multi-category raw materials for unified shipment.
- Original manufacturer TDS, MSDS, and batch COA inspection documents can be provided to purchasing clients. This grade complies with EU REACH and RoHS hazardous substance regulations, fitting terminal product market access reviews across most global regions. Complete material traceability records are established for every arriving batch, allowing traceability back to corresponding inspection logs using the production lot number.
- As a thermoplastic polyolefin material, clean trimming scrap generated during processing can be pulverized and re-granulated for closed-loop recycling; normal molding processing exhibits low VOC emission levels, meeting green supply chain baseline requirements and supporting downstream client ESG supply chain audits.
Frequently Asked Questions (FAQs)
Q1: How should Lucene™ LC170 POE and standard EVA toughening agents be distinguished and selected for PP modification?
A1: LC170 is a polyolefin elastomer whose molecular structure contains no vinyl acetate groups, offering superior temperature and aging resistance compared to EVA, making it less prone to exudation during long-term use; EVA has lower temperature resistance and is better suited for hot-melt systems. LC170 is preferred for modified PP products requiring long-term heat resistance and outdoor exposure.
Q2: What is the conventional addition ratio range when using LC170 to toughen PP?
A2: For boosting room-temperature toughness alone, an addition ratio of 5%~12% is used; for working conditions requiring strict low-temperature impact resistance, a recommended addition ratio of 12%~20% is suggested. Final addition proportions should be determined through sample testing based on target impact metrics and cost budgets.
Q3: Is LC170 suitable for transparent PP systems, and will it affect substrate transparency?
A3: Because an phase interface exists between POE and PP, its addition will reduce light transmittance to a certain extent. High-transparency applications are not recommended for high-volume additions; products with flexible transparency requirements that focus on toughness enhancement can use it normally.
Q4: Can samples be requested for formulation testing? What are the sample shipping requirements?
A4: TaiKuo New Materials supports sample requests for preliminary formulation evaluations. Sample specifications, freight, and delivery timelines can be negotiated separately. Full-scale molding trials and terminal durability validation are recommended before bulk purchasing.
