PEI molding

Stack Plastics works with a broad range of exotic injection molding resins. Not every injection molder takes the trouble to maintain such a large inventory of materials, but we know that this variety ensures that we have the right injection molding resin available for your project’s requirements.

Each of our exotic injection molding resins has unique properties and characteristics makes it ideal for specific applications. We will work with you to determine the correct resin for the needs of your product.

Our selection of exotic injection molding resins includes, but is not limited to:

  • PEEK: An aromatic semi-crystalline polymer with superior strength, stiffness, and impact resistance. PEEK exhibits excellent mechanical properties, high resistance to chemical and thermal degradation, and a highly favorable tensile-strength-to-weight ratio.
  • Avaspire: A modified version of PEEK, this exotic injection molding resin provides even greater durability, ductility, and high temperature resistance. It provides excellent chemical resistance, stiffness, and strength in all applications.
  • PEI (polyetherimide): PEI injection molding resin exhibits excellent rigidity and strength at high temperatures, long-term heat resistance, excellent electrical properties, and good mechanical strength. PEI can be used to replace metal parts in many structural applications.
  • PPS (polyphenylene sulfide): With a tensile strength of 21,800 psi and a UL 90 V-0 flame rating, PPS is excellent for severe applications. It also offers good chemical resistance, good electrical properties, and good dimensional stability.
  • COC (cyclic olefin copolymer): COC provides high clarity and outstanding light transmission, makes an excellent water vapor barrier, and is biocompatible. This exotic injection molding resin is ideal for lenses, touchscreens, and packaging products.
  • COP (cyclo olefin polymer): This resin exhibits high transparency, low water absorption, high thermal stability, and good chemical resistance. Available in multiple grades, COP is an excellent option for lab test equipment, optical components, and antennae.
  • Coolpoly: This heat-conveying polymer is lightweight, cost-effective, and highly moldable, making it ideal for complex designs. Three grades are available, each providing unique benefits for specialized applications.
  • LCP (liquid crystal polymers): With high flow and good mechanical properties, LCP injection molding resin is frequently used in electronics applications. LCP also exhibits high strength at high temperatures and extreme chemical resistance.
  • TPEs & TPUs: TPEs and TPUs are a group of six classes of exotic injection molding resins, all of which exhibit excellent flexibility with durometer levels for Shore A 20 to Shore D 90. These materials do not require stabilizers, cure systems, or reinforcing agents.
  • Pebax (polyether block amides): A popular elastomer for medical devices, Pebax offers very low density, high tensile strength, high flexibility at low temps, and good resistance to many chemical solvents. Three grades are available.
  • PSU (polyphenylsulfone): This thermoplastic injection molding resin exhibits excellent hydrolytic stability and superior toughness. It also provides good chemical and radiation resistance, good dielectric properties, and excellent strength and rigidity.
  • Many other exotic injection molding resins are available upon request. Contact us to discuss your unique material requirements.
