Internal and external Lubricant - Introduction
Open Data Unverified Data
Internal and external lubricants are additives used to improve the processing performance of plastics, especially in the processing and application of bio based plastics, where internal and external lubricants play a crucial role. They are divided into internal lubricants and external lubricants, which are used to improve the processing flowability and surface properties of plastics, respectively.
1. Internal lubricant
Internal lubricant is an additive added inside the plastic melt, mainly used to reduce the internal friction of the plastic during processing, thereby improving its flowability. Common internal lubricants include:
-Fatty acid esters, such as stearic acid esters and palmitic acid esters, can effectively reduce melt viscosity and improve processing efficiency.
-Waxes such as polyethylene wax and Brazilian wax can provide good fluidity in a molten state and form a surface lubricating layer when cooled.
-Fluorinated polymers, such as polytetrafluoroethylene (PTFE), have excellent friction resistance and high temperature resistance, making them suitable for high-temperature processing environments.
2. External lubricant
External lubricants are mainly used for surface treatment of plastic products to improve the smoothness and feel of the surface. The application of such additives can reduce friction between plastic products, prevent adhesion and scratches. Common external lubricants include:
-Siloxanes: can provide excellent smoothness and gloss, enhancing the appearance and feel of products.
-Polyethylene wax: It can be used not only as an internal lubricant, but also as an external lubricant to provide good surface sliding properties.
-Synthetic fatty acid salts, such as polypropylene calcium salts, can form a protective film on the surface of plastics, reducing the friction coefficient.
3. Application in bio based plastics
With the increasing awareness of sustainable development and environmental protection, bio based plastics are gradually receiving attention. The application of internal and external lubricants in bio based plastics mainly includes the following aspects:
-Improving flowability: The use of internal lubricants can significantly enhance the flowability of bio based plastics in injection molding and extrusion processes, reduce processing temperatures, and improve production efficiency.
-Enhanced surface properties: The application of external lubricants can improve the surface properties of bio based plastics, such as smoothness, scratch resistance, and hand feel, making them more in line with market demand.
-Compatibility and compatibility: When multiple biobased materials are mixed and used, appropriate lubricants can improve the compatibility between components and enhance the overall performance of the material.
4. Market Trends and Challenges
With the increasing demand for environmentally friendly materials, the research and development of internal and external lubricants are also constantly advancing. In the current market, natural and renewable lubricant raw materials are increasingly favored, including plant extracts and bio based polymers.
However, the use of lubricants in bio based plastics also faces some challenges, such as:
-Performance optimization: How to optimize the type and amount of lubricant added without affecting other mechanical and processing properties.
-Cost control: The production cost of bio based plastics and their additives is often higher than that of traditional plastics, and in the future, technological progress is needed to reduce costs.
-Standards and regulations: With the expansion of the biobased materials market, relevant standards and regulations are becoming increasingly important, and ensuring product safety and environmental friendliness is the focus of research and development.
As an important additive in the processing of bio based plastics, internal and external lubricants not only improve the processing performance and product quality of materials, but also promote the application of sustainable materials. With the advancement of technology and changes in market demand, the research and application of internal and external lubricants will continue to develop, promoting the green transformation of the plastic industry.
