PPSU – Polyphenylsulfone

PPSU offers excellent impact and chemical resistance. The high heat resistance and excellent hydrolytic stability of PPSU make it an excellent choice for medical devices requiring repeated steam sterilization. PPSU can withstand more than 1,000 cycles of steam sterilization with significant loss of properties.

PPSU is inherently flame retardant. It is transparent and may be colored.

PEI – Polyetherimide

PEI offers elevated thermal resistance, high strength and stiffness, and broad chemical resistance. It is available in transparent and opaque custom colors. PEI is dimensionally stable over a wide temperature range. It is inherently flame retardant.

PEEK – Polyetheretherketone

PEEK is resistant to harsh chemicals with high strength, stiffness and long term creep properties in demanding conditions. PEEK offers low moisture absorption and high wear resistance. It will perform at high temperatures and offers consistent properties across a range of frequencies.

PPS – Polyphenylene Sulfide

PPS offers thermal stability and resistance at elevated temperatures. PPS maintains dimensional stability in a harsh chemical environment. It is inherently flame retardant. Dielectric and insulating properties are stable over a wide range of conditions.

LCP – Liquid Crystal Polymer

LCP provides high-temperature performance in thin-wall applications with precise and stable dimensions. LCP is inherently flame-resistant with good resistance to chemical and oxidation. It has high tensile strength and tensile modulus.

TPU – Thermoplastic Polyurethanes

TPU material bridges the gap between rubber and plastics. TPU is available in grades from the very soft and flexible to very rigid. Many types of TPU comply with FDA food-contact regulations and several meet the biocompatibility tests. TPU resins will bond to a variety of substrates to provide a soft-touch feel.

TPUs have high wear resistance and maintain flexibility over a wide range of temperatures. TPUs have excellent resistance to weathering, oils and greases.

TPE – Thermoplastic Elastomers

TPEs behave like thermoset materials but being processed as a thermoplastic offers a wide design range. The design range of TPEs allows it to be used in many industries and in many ways. It is often used to overmold. TPEs are a mix of Plastic Properties and Elastomeric Properties

TPE Plastic properties:
  • Continuous use temperature
  • Tensile strength
  • Tear strength
  • Chemical and fluid resistance
  • Over-molding substrates
TPE Elastomeric properties:
  • Lower service temperature limits
  • Hardness
  • Flexibility
  • Compression set and tensile set

The combining of Plastic & Elastomeric properties allow for many grades of TPEs to offer solutions to a wide variety of design specifications.

PC – Polycarbonate

PC offers outstanding mechanical, clarity, electrical and thermal properties. PC allows for design versatility. Different options include scratch resistance, toughness, heat resistance, weatherability, biocompatibility and compliance with FDA and USP requirements. Additives allow PC to be flame retardant.

ABS – Acrylonitrile Butadiene Styrene

ABS is a versatile material offering outstanding aesthetics, flow, toughness, dimensional stability, and high temperature resistance. A wide array of ABS grades offer high heat and medical compatibility. There are flame retardant options meeting regulatory standards.
