Important considerations

Pros

  • Heat Resistance: PPSU has a high heat resistance, making it ideal for hot-filled applications or processes.
  • Chemical Resistance: PPSU is extremely durable and resistant to harsh chemicals, making it a great choice for applications involving caustic chemicals.
  • High Impact Strength: PPSU has a high impact strength, making it highly resistant to breaking or shattering from physical impacts.
  • High Flame Resistance: PPSU has a high flame resistance and low smoke emission, making it safer to use in fire-prone environments.
  • Non-Toxic: PPSU is non-toxic and is considered safe to use in applications where contact with food or drink is possible.
  • Low Permeability: PPSU has a low permeability, meaning that it is highly resistant to permeation by gases and vapors.
  • Lightweight: PPSU is lightweight and easy to handle, making it a great choice for applications where lightweight components are needed.
  • Low Maintenance: PPSU is low maintenance and does not require special care or treatment to keep its shape and properties.
  • Cost Effective: PPSU is a cost effective material, making it a great option for applications where cost savings are needed.

Cons

  • High Cost: PPSU is generally more expensive than other materials used in plastic products, such as ABS, PC, or nylon.
  • Limited Machine Compatibility: PPSU is difficult to mold or extrude due to its high melting temperature, so only certain types of machinery are compatible with this material.
  • Poor Chemical Resistance: PPSU is susceptible to damage from many chemicals, including solvents and cleaning agents.
  • Difficult to Bond: PPSU is not easily bonded with other materials, making it difficult to create multi-material products.
