Descrizione dei prodotti
Coace® W1F-2 è un tipo di copolimero a base di propilene funzionalizzato chimicamente con una bassa temperatura di transizione vetrosa. Possiede un'elevata fluidità durante il processo di produzione.
In order to improve the performance properties of polyamide 6 (PA6) compounds, particularly in terms of impact resistance and processability, high fluidity impact modifiers must be used. These impact modifiers, which are mostly chemically functionalized propylene-based copolymers, have a number of benefits that help PA6’s mechanical characteristics and manufacturing capabilities.
Impact modifiers with high fluidity constitute a noteworthy development in the improvement of PA6 compounds. Superior impact resistance, processability, and overall toughness are provided by their chemical functionalization, which is based on propylene copolymers. Their performance is further improved by their low glass transition temperature, which makes them appropriate for a variety of applications in a range of sectors.
Due to their distinct properties, such as their low Tg, high fluidity, and chemical makeup, high fluidity impact modifiers are essential additions for high-performance PA6 compounds. Their employment in the packaging, sports equipment, automotive, consumer electronics, home appliances, and industrial component industries demonstrates how adaptable and successful they are in enhancing material qualities.

- Chemical Functionalization: The basis of high fluidity impact modifiers for PA6 is propylene copolymers that have undergone chemical functionalization. Reactive groups are added to the copolymer backbone during the functionalization process, and these groups might interact with the PA6 matrix. Improved mechanical qualities result from this interaction’s improvement of the impact modifier and polyamide’s compatibility and adherence.
- Copolymer with propylene base: Propylene copolymer serves as the foundation material for these impact modifiers, offering a suitable combination of stiffness and flexibility. The copolymer structure permits alterations that can improve particular characteristics, such impact resistance, without sacrificing the material’s general stability and strength.
- Excellent Flow: Their extreme fluidity is one of these effect modifiers’ primary characteristics. The ease with which the material can flow throughout processing is referred to as high fluidity. In order to achieve homogeneous dispersion of the impact modifier within the PA6 matrix and guarantee consistent performance and quality in the finished product, this property is essential.
- Low Temperature of Glass Transition: The low glass transition temperature (Tg) of the impact modifiers adds to their flexibility and resilience to impacts. Even at lower temperatures, a low Tg guarantees that the material retains its ductility and efficiently absorbs impact energy.
Vantaggio
1. Enhanced Resistance to Impact
The major increase in impact resistance of PA6 compounds is the main benefit of applying high fluidity impact modifiers. By strengthening the link between the modifier and the PA6 matrix, the chemical functionalization lowers the probability of brittle failure by improving the material’s ability to absorb and dissipate energy.
2. Improved Capability to Process
Impact modifiers with high fluidity enhance PA6’s processability. The modifier is uniformly dispersed and integrated inside the polymer matrix thanks to the processing’s ease of flow. This makes the finished product’s mechanical qualities more dependable and consistent and makes production procedures like extrusion and injection moulding easier.
3. Improved Finish on the Surface
The moulded or extruded items have a superior surface polish as a result of the impact modifiers’ high fluidity. This is especially crucial for applications where smoothness and surface aesthetics are vital. Better flow properties make it easier to fill moulds evenly and fully, which lowers the likelihood of flaws like sink marks or voids.
4. Enhanced Hardness
The modifiers not only increase impact resistance but also the overall toughness of PA6 compounds. This indicates that the material can experience substantial deformation prior to breaking, which is essential for uses where high durability and resistance to mechanical stress are required.
5. Resistance to Temperature
These modifiers’ low glass transition temperatures guarantee that the modified PA6 maintains its toughness and impact resistance throughout a wide temperature range. Because of this, the material can be used in applications where it is subjected to a wide range of temperatures.
