POM, or polyoxymethylene, is an important engineering plastic with excellent physical and chemical properties and is widely used in many fields. This paper will focus on the characteristics, application areas, advantages, and disadvantages as well as processing difficulties of POM materials, and discuss the enhancement of the processing performance and surface quality of POM materials by organosilicon additives and silicone masterbatch.
Properties of POM material:
POM is a kind of engineering plastic with excellent physical properties, high strength, high stiffness, good abrasion resistance and chemical resistance, etc. POM material has a low coefficient of friction and good self-lubrication, so it is widely used in the fields of mechanical parts, automotive parts, electronic products, and so on.
Application areas of POM materials:
POM materials are widely used in a variety of fields that require high strength, high stiffness, and wear resistance, such as automotive manufacturing, aerospace, medical devices, electronic products and so on. In the field of automotive manufacturing, POM materials are commonly used in the manufacture of automotive parts, such as door handles, exhaust pipe brackets, etc.; in the field of electronic products, POM materials are commonly used in the manufacture of electronic housings, keyboard buttons and so on.
Advantages of POM materials:
1. High strength and high stiffness: POM materials have excellent mechanical properties and are suitable for applications subject to high-strength loads.
2. Good wear resistance and chemical resistance: POM materials have good wear resistance and chemical resistance, suitable for high friction and corrosive environments.
3. Self-lubrication: POM materials have good self-lubrication, reducing the friction loss between parts.
Disadvantages of POM material:
1. Easy to absorb moisture: POM material is easy to absorb moisture and is prone to deformation in high humidity environments.
2. Difficult to process: POM material is difficult to process and prone to defects such as thermal stress and bubbles.
The effect of silicone additives and silicone masterbatch on POM materials:
Silicone additives and silicone masterbatch are commonly used POM material modifiers, which can effectively improve the processing performance and surface quality of POM materials. Silicone additives and silicone masterbatch can improve the processing fluidity of POM materials and reduce the processing of air bubbles; silicone masterbatch can improve the surface finish of POM materials and abrasion resistance so that the products are more suitable for demanding applications.
SILIKE—Specialised in combining silicone and plastics for more than 20 years
SILIKE Silicone Masterbatch ( Siloxane Masterbatch ) LYSI-311 is a pelletized formulation with 50% ultra-high molecular weight siloxane polymer dispersed in Polyformaldehyde ( POM ). It is widely used as an efficient processing additive in POM-compatible resin systems to improve the processing properties and modify surface quality.
Compared to conventional lower molecular weight Silicone / Siloxane additives, like Silicone oil, silicone fluids, or other type processing aids, SILIKE Silicone Masterbatch LYSI series are expected to give improved benefits, eg,. Less screw slippage , improved mold release, reduce die drool, a lower coefficient of friction, fewer paint and printing problems, and a broader range of performance capabilities.
SILIKE Silicone Masterbatch ( Siloxane Masterbatch ) LYSI-311 is suitable for POM compounds and other POM-compatible plastics. A small amount of SILIKE Silicone Masterbatch ( Siloxane Masterbatch ) LYSI-311 can improve processing performance, provide better processing fluidity, reduce extruder torque, improve die mouth build-up, and have better film filling performance and mould release performance. It can provide better surface performance, reduce the coefficient of friction, and improve surface slippage. Improve the surface abrasion and scratch resistance of products. Improve production efficiency and reduce product defective rate. Compared with traditional additives or lubricants, it has superior stability.
SILIKE LYSI series silicone masterbatch may be processed in the same way as the resin carrier on which they are based. It can be used in classical melt blending processes like Single /Twin screw extruders, and injection molding. A physical blend with virgin polymer pellets is recommended.
Conclusion: POM material, as an important engineering plastic, has a wide range of application prospects in many fields. Through a reasonable choice of silicone additives and silicone masterbatch, the processing performance and surface quality of POM materials can be effectively enhanced, further expanding its application areas and market prospects. SILIKE, the trusted leader in silicone-plastic combinations for over two decade,and has a wealth of plastics processing solutions.
