GEHR POM banner

Applications:Parts & Components, Medical, Laboratory & Diagnostics
Product Families:Parts, Shapes & Films, Parts & Shapes
Polymer Name:Polyacetal Copolymer (POM)
End Uses:Medical Devices, Medical Device Housings, Conveyors

Due to its good thermal and mechanical properties, this semi-crystalline material belongs to the polymer group of engineering plastics. It has a high surface hardness and good sliding and wear behavior. Since POM belongs to the group of short-chip materials, machining is significantly simplified when compared to similar plastic materials.

Applications:Medical, Cooling & Climate, Medical Devices & Assemblies
Product Families:Parts, Shapes & Films
Chemical Family:Polycarbonate (PC)
Polymer Name:Polycarbonate (PC)
End Uses:Medical Devices, Electrical/Electronic Applications, Medical/Healthcare Applications

Polycarbonate is a transparent material and belongs to the group of amorphous engineering plastics as well as to the polyester family of plastics. It has a high stiffness and extremely high impact strength. It also has a high glass transition temperature and heat deflection temperature (approx. +130 °C). The continuous operating temperature of PC ranges between approximately -60 °C and +120 °C. The material is highly resistant to high-energy radiation. However, it must be stabilized against UV rays, otherwise yellowing may occur. Like all polyesters, PC is not resistant to hot water (from approx. +60 °C) in the long term.

GEHR PVDF banner

Applications:Medical Devices & Assemblies, Equipment & Parts, Other Industrial Applications
Product Families:Parts, Shapes & Films
Chemical Family:Vinyls, Vinylics & Vinyl Derivatives
Polymer Name:Polyvinylidene Fluoride (PVDF)
End Uses:Medical Devices, Gaskets, Valves

Polyvinylidene fluoride shows a higher tensile strength, pressure resistance and dimensional stability than the related PTFE, but friction and insulation properties are lower. PVDF has a high mechanical strength and toughness at lower temperature and it’s self-extinguishing. The operating temperature ranges from -30 °C to +150 °C. PVDF shows a high resistance to chlorine, bromine and high-energy radiation.

GEHR PPSU banner

Applications:Medical Devices & Assemblies, Equipment & Parts, Pumps, Turbines & Compressors
Product Families:Parts, Shapes & Films
Chemical Family:Polyphenylene Sulfide (PPS)
Polymer Name:Polyphenylene Sulfide (PPS)
End Uses:Medical Devices, Pump Parts, Microwave Cookware

Polyphenylensulfone is an amorphous material, with improved impact and hydrolysis resistance compared to PSU. This amber-colored, transparent material is usually used in a black color, which is why we only offer it in this color version so far. The usual operating temperature is approx. +170 °C. The extremely high notch impact strength remains also after a heat aging.

GEHR PSU banner

Applications:Medical Devices & Assemblies, Equipment & Parts, Other Industrial Applications
Product Families:Parts, Shapes & Films
Chemical Family:Polysulfones
Polymer Name:Polysulfone (PSU)
End Uses:Medical Devices, Food Packaging, Valves

This amber-colored, transparent material belongs to the group of amorphous high-performance plastics. Polysulfone has a good heat deflection temperature and heat aging resistance (-100 °C to +160 °C). In addition, this material has a high hardness and strength, very good hydrolytic stability and high radiation resistance (permeable to microwaves up to 2.45 GHz). PSU also has high dimensional stability and resistance to β- and γ-, X-rays and infrared rays. However, PSU is not UV stable and notch sensitive.
