Introduction to Polyoxymethylene (POM)
Polyoxymethylene (POM), also known as acetal, polyacetal, or polyformaldehyde, is a high-performance engineering thermoplastic renowned for its exceptional mechanical properties and dimensional stability. It’s widely used in industries that require precision and durability, such as automotive, electronics, medical devices, and consumer goods.
The Latest Sustainable POM Technology: Short Cellulose Fiber Reinforced Grades
Polyplastics has recently unveiled a new range of DURACON® POM grades reinforced with short cellulose fibers. This innovation addresses the growing need for sustainable materials without compromising performance. Unlike traditional glass-filled POM, these short cellulose fiber-reinforced grades significantly increase flexural modulus while maintaining lightweight and high rigidity.
Cellulose, a non-edible, bio-based material, contributes to environmental sustainability and is recognized as a carbon-negative material that absorbs CO2. When paired with carbon steel (S45C), these new POM grades exhibit a lower dynamic friction coefficient and reduced wear, making them ideal for demanding applications requiring both high rigidity and excellent sliding properties.
How can we enhance POM’s wear resistance without sacrificing performance or sustainability?
Addressing the Challenges of Wear and Friction in POM
Despite these advancements, many POM materials still face significant challenges with wear and friction, especially in high-demand applications like automotive, electronics, and consumer goods.
Some of the most common methods used to enhance the wear resistance of POM include:
1. PTFE Additives: Polytetrafluoroethylene (PTFE) can significantly reduce friction and wear in POM. However, excessive amounts can weaken the material’s mechanical strength, so a balanced dosage is key.
Additionally, PTFE belongs to a group of substances known as per- and polyfluoroalkyl substances (PFAS). Due to the potential health and environmental risks associated with PFAS, the European Chemicals Agency has published a proposal from five member countries to ban PFAS that contain at least one fully fluorinated carbon atom—an estimated 10,000 different molecules, including popular fluoropolymers. Member states are set to vote on this ban in 2025. If the European proposal remains unchanged, Should the proposal proceed without changes, it may lead to significant shifts in the use of common fluoropolymers like PTFE and PVDF, prompting us to explore safer alternatives and innovative solutions.
2. Inorganic Lubricants: Molybdenum disulfide, boron nitride, and similar inorganic materials can form a transfer film on POM’s surface, reducing friction and improving wear resistance. However, these additives must be carefully selected to avoid compromising POM’s thermal stability.
Innovative Solutions for Superior Wear Resistance in POM
For those seeking to further enhance POM’s wear resistance, SILIKE offers a range of specialized eco-Friendly additives designed to improve durability and processing properties:
1. Silicone Masterbatch (Siloxane Masterbatch) LYSI-311: This pelletized formulation contains 50% ultra-high molecular weight siloxane polymer, dispersed in POM. It enhances the processing properties and surface quality of POM, making it a go-to additive for improving performance in various applications.
2. Wear Resistance Additive for POM compounds: SILIKE’s expanding family of silicone additives greatly enhances the surface properties of polyoxymethylene (POM) compounds.
We are proud to introduce our latest addition to the family of silicone additives, LYSI-701. This innovative silicone additive is specifically designed to enhance the wear resistance of polyoxymethylene (POM) compounds. With its unique poly-siloxane structure, LYSI-701 disperses evenly throughout the POM resin, effectively forming a lubricating layer on the surface. This advancement significantly reduces the coefficient of friction (CoF), while also improving abrasion and mar resistance. As a result, LYSI-701 contributes to the overall durability and longevity of POM materials, making it a valuable solution for various applications.
Key Benefits of using these silicone additives include:
1. Reduced Friction: The unique polysiloxane structure forms a lubricating layer on POM, lowering friction and boosting wear and mar resistance,while maintaining excellent mechanical properties.
2. Improved Aesthetic Quality: The siloxane additive imparts a smooth surface finish, enhancing the visual appeal of finished products.
3. Optimized Processing: this Anti-abrasion Masterbatch improves moldability and release properties, enhancing manufacturing efficiency and product quality.
4. Eco-friendly and Safe:silicone additives is non-toxic, odorless, and environmentally friendly, meeting ROHS standards and REACH pre-registration requirements.
Applications of siloxane additives in High-Performance POM Components
These Plastics Additives and Polymer modifiers particularly LYSI-311 and LYSI-701, are ideal for high-performance POM components used in manufacturing applications, such as:
· Gears, Bearings, and Conveyor Belts: Where wear resistance and durability are paramount.
· Automotive: Including window lifting systems and steering column sensors.
· Consumer Goods: Household appliances, sports equipment, and other items requiring high wear resistance.
By incorporating these silicone-based additives into POM formulations, POM manufacturers can significantly improve the mechanical properties and longevity of their products while reducing friction, wear, and environmental impact.
