Plastic materials and properties

The choice of material for Plastic machined parts is based on the properties of the Plastic material. The following are some examples of commonly used materials

Material name Properties
4F PTFE (Fluoride) Very good chemical stability and electrical properties. Slightly lower hardness. Good machinability, insulation, and heat resistance. Used for insulating parts in various fields and as a material for parts that require heat and corrosion resistance. Some materials have fillers such as carbon or glass fiber to increase the impact force.
Polyacetal Excellent insulation, heat resistance, chemical resistance, and hardness. The cost of the material is lower than that of 4F, so it is used in many fields as an insulating material.
Polyvinyl chloride (PVC) Two types, grey and transparent. Slightly lacking in heat resistance, but with good water resistance, it is used as a material for pipes and joint parts for fluids. It also has good workability and insulation properties.
3F PCTFE (Fluoride) The cost of the material is high, but it has excellent insulation and impact resistance. It is also extremely resistant to acids, alkalis and other chemicals and is therefore used as a material for pipes and joint parts for various fluids.
Polycarbonate Excellent in heat and impact resistance. Polycarbonate has low shrinkage and good dimensional stability. It is also resistant to water. Not so good in machinability.
Acrylic Transparent, so you can see what's inside. It is highly resistant to water and is used for pipes and prototypes for various fluids.
Nylon Flexible and resistant to breakage. Nylon is used for packing and other applications due to its resistance to water.
