Excellent low-temperature toughness: Glass transition temperature as low as -54 ℃, maintaining good elasticity in low-temperature environments and resisting brittle fracture.
Ultra-high elongation at break (>550%): Excellent elasticity and high resistance to deformation, making it ideal as a toughening modifier.
Good polyolefin compatibility: Can be blended and modified with PP and PE substrates to enhance the impact resistance of the base material.
Stable processing performance: Melt index of 5.0 g/10min, suitable for processing technologies such as extrusion, injection molding, and compounding granulation.
Low density (0.865 g/cm³): Helps reduce unit weight and control raw material costs for finished products.
Good tear resistance: Tear strength of 20.0 kN/m, enhancing the tear-resistant durability of modified products.
Automotive Modified Plastics: PP-modified automotive bumpers and interior parts, improving low-temperature impact resistance and reducing the risk of component cracking in cold environments.
Plastic Toughening Modification: PP and PE substrate toughening agents used for compounding and granulation to enhance the toughness of general-purpose and engineering plastics.
Elastic Extrusion Products: Hoses, weatherstripping, and elastic films utilizing high elongation and elasticity to produce flexible rubber-plastic accessories.
Wire and Cable Materials: Used as a toughening component in polyolefin cable compounds to improve the low-temperature elasticity of cable jackets.
Daily and Industrial Elastic Accessories: Flexible gaskets, cushioning and shock-absorbing parts, and plastic toy toughening modification.
Q1: Does LG Chem Lucene™ LC565 POE need to be dried before processing?
A1: Lucene™ LC565 POE has extremely low water absorption and generally does not require pre-drying under normal storage conditions. If the raw material is exposed to a high-humidity environment for a long time, it is recommended to dry it at 60–80 ℃ for 2–4 hours to avoid bubble defects on the product surface.
Q2: Which plastics are primarily modified by LC565 POE? Can it be blended with PA and PC?
A2: This POE grade has optimal compatibility with PP and PE polyolefin substrates and is primarily used for PP/PE toughening. Ungrafted LC565 has poor direct compatibility when blended with PA and PC; if toughening nylon or PC is required, grafted POE grades are recommended.
Q3: Does LG Chem Lucene™ LC565 meet RoHS environmental requirements?
A3: LG Chem’s original Lucene™ series products can provide RoHS compliance reports, and original manufacturer material certificates can be provided with shipments for projects exporting to the EU. Specific compliance documents can be requested from ZiJun Plastics.
Q4: How does LC565 compare to other POE grades, and what application scenarios is it suitable for?
A4: LC565 has a Shore hardness of 54A and medium fluidity, with standout advantages being an extremely low Tg and ultra-high elongation. It is primarily recommended for low-temperature toughening scenarios. If higher hardness or a higher melt index POE is needed, other grades in LG Chem’s Lucene series can be referenced: LG Chem Resin Products
