Distributor in Europe for Polyimides from RBI

At High3P we provide a large choice of Polyimide products in different forms for a variety of markets and applications. When it comes to challenging projects, our 50-plus years’ experience in High Performance Polymers and their markets make us a strong partner. We bring to your project deep technical support at all levels, including assistance with material selection up to compound/formulation development, design (for machined parts) and cost optimization. For most products we can ensure short lead times; MTO grades usually require 3-5 weeks.

Polyimide

  • Properties
  • Many of the highest performances of all thermoset and thermoplastic polymers
  • Stands out with its high and low temperature characteristics, resistance to chemicals and fire, dielectric strength, friction and wear properties, adhesion to many substrates and many more
  • Processing
  • Demands specific experience and capabilities
  • Thermal treatment to achieve the highest possible performance
  • Most widely used technologies: casting and coating (liquid solutions), compression molding, direct forming (semi-finished and 3D parts), machining from stock shapes
  • Markets / Applications
  • Reference material in Semicon: film layer, dielectric coating, stress buffer, insulation films, chip bonding; clamp rings, CMP rings, test sockets, probe heads
  • Coating and / or cladding of high performance Optical Fibers
  • Electrics and Electronics: Cu foil films, cast films, wire enamel
  • Li-Ion batteries: binder for electrodes
  • Protective Coating of metal, ceramic and glass surface; tubing
  • Highest performance friction & wear and structural parts in Automotive, Aerospace, Industrial: bearings, sealings, plasma torches, …
  • High temperature gas separation Membranes

We offer VTEC™ Polyimide in various Product Forms.

Liquid solution

  • Characteristics and Benefits
  • Very advanced chemistry with extremely fast release of the carrier solvent, drying and imidization (compared to competitive products)
  • Self-leveling, smooth and pin-hole free drying
    à faster processing, high productivity and quality coating, and film casting
  • Readily accepts and evenly disperses filler additives                                               à to gain ESD, increased wear resistance or strength
  • Optically clear, extra low moisture absorption, high flexibility, non-crystallizing amorphous, and new custom base polymers available
  • Onset of degregation >450 °C
  • Long shelf life; -20 °C freezer storage suggested
  • Solvent: NMP (N-Methyl-2-Pyrrolidone)
  • Packaging: 100g, 250g, 500g, 1000g, gallon, barrels of 5 kg and more
