High Grafting Rate Coupling Agent for Polyethylene-Based Compounds
COACE's main products are compatibilizers, tougheners and functional additives, which are used in: modified plastics, wood-plastic profiles, low-smoke halogen-free flame-retardant cables, PP extruded sheets, PE extruded sheets, and anti-corrosion pipes Coatings, hot melt adhesives, photovoltaic film additives and other fields, among which special products such as nylon ultra-low temperature toughener, polyester compatible toughener, alloy compatibilizer have reached the domestic advanced level.
Coace® W1L-B is a type of anhydride-modified low-density polyethylene (LLDPE) that possesses a high grafting rate and a high fluidity.
The anhydride-modified LLDPE coupling agent overcomes compatibility issues by utilizing the power of anhydride functionality. The addition of anhydride groups to the LLDPE backbone allows for strong interactions and chemical bonding between the PE and other polar phases, thereby bridging the gap between non-polar and polar components.
The anhydride-modified LLDPE coupling agent is a significant improvement in polymer technology, particularly for polyethylene-based compounds. By efficiently addressing compatibility issues between PE and polar materials, the coupling agent enables the development of high-performance, multi-functional materials with improved mechanical capabilities, thermal stability, and chemical resistance. With its diverse uses across industries, the anhydride-modified LLDPE coupling agent is positioned to play a critical role in the future of innovative polymer-based materials.
1. High Grafting Rates for Better Compatibility:One of the most notable characteristics of the anhydride-modified LLDPE coupling agent is its extremely high grafting rate. This high grafting rate is obtained by carefully optimizing the manufacturing process, which ensures a strong and uniform distribution of the anhydride functional groups along the LLDPE backbone. The high grafting rate is critical for enhancing the compatibilizing effect, which results in improved interfacial adhesion and overall performance of polyethylene-based compounds.
2. Improved Mechanical Performance: The improved compatibility provided by the anhydride-modified LLDPE coupling agent results in significant improvements in the mechanical characteristics of polyethylene-based compounds:
3. Tensile Strength: Improved interfacial adhesion between the PE and polar phases increases tensile strength, allowing for the development of stronger and more lasting PE-based components.
4. Impact Resistance: The coupling agent's capacity to increase stress transfer between the PE and polar phases improves the compound's overall impact resistance, making it more appropriate for applications requiring high impact resistance.
5. Toughness: The compatibilizing action of the anhydride-modified LLDPE coupling agent achieves an optimal compromise between PE's intrinsic toughness and the impact resistance of the polar components, resulting in a polyethylene-based compound with increased overall toughness.
6. Thermal and Chemical Stability: In addition to increased mechanical qualities, the anhydride-modified LLDPE coupling agent improves the thermal and chemical stability of polyethylene-based compounds:
7. Thermal Resistance: The anhydride activity of the coupling agent can interact with the compound's polar groups, improving thermal stability and widening the temperature range for safe and dependable use.
8. Chemical Resistance: The compatibilizing action of the anhydride-modified LLDPE coupling agent can increase the compound's resistance to a variety of chemicals, solvents, and environmental variables, making it more appropriate for applications where such conditions are a concern.
