Dendritic PP toughening agent is a polyolefin-based toughening agent with a dispersing function of a dendritic structure. It has excellent toughening effects and can significantly improve the melt flow properties of polyolefin-based materials.

Basic information on dendritic PP tougheners

Exterior Granules Application Plastic processing aid

Advantages of dendritic PP tougheners

1. Dendritic tougheners can take into account both fluidity and toughness. In the application of polypropylene products with medium melting index, compared with the same amount of POE system, the impact can be increased by more than 30%, and the melting index can be increased by more than 50%.

2. Compared with the traditional POE, the dendritic toughener has better dispersibility, the rigidity of some formulas is greatly improved, the flexural modulus can be increased by up to 70%, and the tensile strength is increased by more than 10%.

Principle of dendritic PP toughener

1. The flexible polyolefin long chain segment in the dendritic toughener plays a role of coupling and buffering between molecular chains;

2. A large number of flexible long-chain functional groups on the surface of the dendritic polymer can more easily form a three-dimensional network structure through molecular interactions in the system;

3. The dendritic polymer has a space-spherical structure, has a smaller hydrodynamic radius, and exhibits significant low melt viscosity characteristics, which can greatly improve the melt flowability of polyolefin materials such as PP.

Applicable system of dendritic PP toughener

PP filling system is especially suitable for high filling and toughening systems. The higher the filling ratio, the better the effect.

Application fields of dendritic PP toughener

PP products, such as car bumpers, interior and exterior trim (door panels, instrument panels, etc.), housings for household appliances, daily necessities (trash bins, etc.), PE brushed lawn
