Products Description
Coace® B1 is a maleic anhydride modified polypropylene with high grafting rate.
The polypropylene polymer is at the heart of the coupling agent, acting as its backbone. Maleic anhydride (MA) is grafted onto PP chains at a faster pace than traditional MAPP coupling agents thanks to a focused chemical modification approach. The higher grafting density of MA moieties along the polymer backbone is the primary differentiating feature of coupling agent, resulting in improved functionality and performance.
The high grafting rate polypropylene coupling agent, a maleic anhydride modified polypropylene, is a notable achievement in the field of polymer modification. Its ability to improve adhesion, mechanical characteristics, and thermal stability makes it a beneficial additive in a variety of applications. Its diverse performance benefits industries ranging from automotive to construction, packaging, and electronics, resulting in products with improved quality and durability.
By efficiently resolving the limits of pure polypropylene, this coupling agent creates new opportunities for material innovation and product development. Whether improving the strength and longevity of automotive components, increasing the durability of construction materials, or ensuring the dependability of consumer goods, the high grafting rate polypropylene coupling agent is a critical component in modern manufacturing and material science.

- High Grafting Efficiency: The product has a high level of grafting, which means that a large number of MAH groups are chemically attached to the PP backbone. This high grafting rate is critical for getting the most out of the coupling agent’s performance.
- Thermal Stability: The modified polypropylene has exceptional thermal stability, allowing it to tolerate the high processing temperatures seen in polymer extrusion and molding operations.
- Compatibility: This coupling agent works well with a variety of polypropylene grades, including homopolymers and copolymers. It is compatible with a variety of fillers and reinforcements, including glass fibers, mineral fillers, and wood flour.
- Improved Mechanical Properties: The addition of MAH groups improves the mechanical properties of PP composites by increasing filler dispersion and adherence within the polymer matrix.
Advantage
The maleic anhydride modified polypropylene coupling agent has several important benefits, making it a vital component in many applications:
Enhanced Adhesion: The polarity of the MAH groups increases adhesion between PP and polar substrates or fillers. This produces composites with greater mechanical integrity and durability.
Increased Wettability: The polar alteration improves the wettability of polypropylene, allowing for better mixing and dispersion of additives and fillers, resulting in enhanced composite characteristics.
Versatility: Because of its high grafting rate and compatibility with a wide range of materials, this coupling agent is suitable for a variety of formulations and processing processes, including extrusion, injection molding, and blow molding.
Improved Mechanical Strength: Composites containing this coupling agent have higher tensile strength, impact resistance, and flexural characteristics, making them appropriate for demanding applications.
Chemical Resistance: The modified polypropylene retains the base polymer’s natural chemical resistance while providing enhanced adhesion to polar materials, hence expanding the spectrum of potential applications.
