Lutene® MB9500 offers balanced base performance, but the following core differentiators allow it to stand out among similar materials:
Ultra-high Productivity: Due to its ultra-high melt index and excellent flowability, it enables exceptionally short cycle times during the injection molding process, significantly increasing output per unit of time and reducing overall production costs.
Excellent Surface Gloss & Clarity: Finished products exhibit a bright, smooth surface with superb optical effects, enhancing the aesthetic quality of end-products and making it suitable for high-end consumer goods.
Superior Low-Temperature Resistance & Flexibility: The material maintains good flexibility and impact resistance even in cold environments. With a low-temperature brittleness point below -45°C, it is highly resistant to cracking, making it ideal for frozen environments or products used in severely cold regions.
Excellent Dimensional Stability: MB9500 features low molding shrinkage, providing outstanding dimensional stability. This allows for precise control over the final product’s geometry and reduces defect rates, especially for injection molded parts with tight tolerances.
Good Chemical Resistance: Inheriting the inherent chemical stability of LDPE, it is highly resistant to acids, alkalis, and various solvents, ensuring reliability across a wide range of operating environments.
With its extraordinary combination of properties, Lutene® MB9500 plays a vital role across several consumer and industrial sectors:
Household Articles: One of the most common applications for MB9500. Its high flowability allows the material to fill complex molds quickly, making it perfect for producing various sizes of lids, storage boxes, dishes, and other housewares.
Powder Coating: MB9500 possesses excellent grinding characteristics and uniform particle distribution, making it an ideal base resin for powder coatings. Once applied to metal surfaces, it forms a smooth, high-adhesion, and weather-resistant protective layer.
Artificial Flower & Grass: Leveraging its flexibility and weatherability, MB9500 is widely used as the plastic substrate for manufacturing realistic and durable artificial flowers and turf.
Foaming Applications & Color Masterbatch: In PE foaming products, MB9500 provides a uniform cell structure. Additionally, its superior flowability makes it an ideal carrier resin for color masterbatches.
To address common concerns during procurement and application, we have summarized the following high-frequency questions:
1. What is the primary processing method for Lutene® MB9500?
MB9500 is a professional Injection Molding Grade. Its ultra-high melt index provides excellent flowability, allowing it to easily fill complex mold designs. Therefore, injection molding is the ideal and most common processing method. It can also be used for compression molding and certain powder coating applications.
2. Does the product meet international food-contact compliance requirements?
While MB9500 performs excellently in terms of hygiene and safety, we strongly recommend requesting the latest compliance statements (such as FDA or RoHS) directly from LG Chem or an authorized distributor before using it for food-contact or medical applications, as certifications may vary by batch or region.
3. What core quality indicators should be prioritized during procurement?
When sourcing Lutene® MB9500, buyers should focus on two core parameters: Density (0.913 g/cm³) and Melt Index (52 g/10min). Additionally, ensure pellets are not exposed to moisture before processing (though PE has low moisture absorption) and verify that the elongation at break of the finished part meets industry standards (> 400%). To ensure genuine material and consistent quality, it is recommended to purchase through LG Chem’s official distribution network and request a Certificate of Analysis (COA).
