Appearance: NA11 generally appears as a white to light yellow powder or granule.
The main functions of nucleating agent NA11 are:
1.Improvement of Material Transparency: NA11 alters the crystallization behavior of polymers, resulting in smaller crystal sizes, which enhances the transparency and gloss of the material.
2.Increased Rigidity and Heat Distortion Temperature: The nucleating agent raises the crystallinity of the polymer, thereby increasing the rigidity and improving the heat distortion temperature, which provides better dimensional stability at higher temperatures.
3.Shortened Molding Cycle: The addition of the nucleating agent accelerates the crystallization rate of the polymer, reducing cooling time and increasing production efficiency.
4.Enhanced Mechanical Properties: NA11 enhances the impact resistance and wear resistance of the material, while also improving its toughness and hardness to some extent.
How to use Nucleating agent NA11?
Nucleating Agent NA11 (Sodium 2,2'-Methylene-bis(4,6-di-tert-butylphenyl)phosphate) is typically used in polymer production, especially for enhancing the properties of polypropylene (PP). Here’s how it is commonly utilized:
Usage in Production:
Incorporation:
NA11 is added to the polymer resin in a concentration typically ranging from 0.1% to 0.3% by weight, depending on the desired level of clarity and mechanical properties.
It is mixed into the polymer during the compounding process, where it is thoroughly dispersed within the polymer matrix.
Processing:
The polymer containing NA11 is then subjected to processes like extrusion, injection molding, or blow molding. The nucleating agent promotes the formation of smaller, more uniform crystalline structures during cooling, leading to improved transparency and mechanical strength.
Effects:
Enhanced Transparency: NA11 reduces the size of spherulites formed during crystallization, which increases the transparency of the final product.
Improved Mechanical Properties: The smaller and more uniform crystals lead to better stiffness and impact resistance.
Faster Processing Times: By promoting faster crystallization, NA11 can help reduce cycle times in injection molding or other processes.
Application Examples:
Packaging: Used in the production of clear, rigid containers.
Automotive Parts: Enhances the mechanical properties of interior and exterior components.
Household Items: Improves the appearance and strength of various consumer goods.
The exact dosage and method of incorporation might vary based on specific product requirements and processing conditions. It is always advisable to conduct trials to determine the optimal conditions for each application.
Differences Between Clarifying Agents and Nucleating Agents
Clarifying Agents:
Purpose: Clarifying agents are primarily used to enhance the transparency of polymers, especially polypropylene (PP).
Working Mechanism: They work by inhibiting the formation of large spherulites during the crystallization process of polymers. Smaller spherulites scatter less light, resulting in a material with higher clarity.
Applications: Clarifying agents are commonly used in applications requiring high transparency, such as clear food containers and household appliance components.
Nucleating Agents:
Purpose: Nucleating agents are designed to accelerate the crystallization speed of polymers, enhancing their rigidity, thermal properties, and overall mechanical performance.
Working Mechanism: Nucleating agents provide additional nucleation sites within the polymer, leading to quicker and more uniform crystallization. This results in a finer crystalline structure that improves the material's rigidity and heat resistance, while also reducing cycle times during processing.
Applications: Nucleating agents are widely used in improving the mechanical properties of products, such as in automotive parts, household goods, and packaging materials.
Summary:
Clarifying agents are mainly used to improve transparency, while nucleating agents are used to enhance mechanical properties.
Clarifying agents are often utilized in producing more transparent plastic products, whereas nucleating agents are used in manufacturing more durable, high-performance plastic items.
