Specifications

Fluoropolymers Used:

 

  • PE and PP: High purity applications.
  • PVDF: Cost-effective with resistance to many chemicals, including bromine; commonly used in ultra-pure water systems.
  • ECTFE: Offers chemical resistance and results in a smooth surface; often used in ultra-pure water systems and high purity applications.
  • ETFE: Utilized only for rotolining; ideal for high purity applications.
  • PFA: Provides universal chemical resistance.

 

Typical Applications:

 

  • Filter housings
  • Columns
  • Vessels, vessel covers, and heads
  • Spool sections
  • Complex shapes
  • OEM free-standing parts

Technical Data

Rotomolding:

 

Process: Plastic resin is melted in a heated metal mold and rotated on multiple axes. The molten plastic coats the interior surface evenly, creating a uniform thickness.

 

Advantages:

  • Low-cost tooling with no core required.
  • Stress-free parts due to the absence of core pressure.
  • Design flexibility for mold modifications after prototyping.

 

Rotolining:

 

  • Process: Similar to rotomolding, but the metal mold becomes the exterior of the finished part. Ideal for complex shapes or thicker fluoropolymer linings.
  • Fluorolock (TM): Variation for elevated temperatures or vacuum applications. Includes a wire screen or mesh welded to the interior of the metal before rotolining, creating a stronger mechanical bond.

Advantages

Rotomolding:

 

  • Cost-effective tooling.
  • Stress-free, seamless parts.
  • High design flexibility.

 

Rotolining:

 

  • Suitable for complex geometries and thicker linings.
  • Enhanced mechanical bond with Fluorolock for severe conditions.
