Materials

HNBR and NBR

Acrylonitrile-Butadiene Rubber (NBR) is a good choice for applications where seals will not be exposed to harsh cleaning regimes, ozone or superheated steam. These materials offer:

• Good mechanical properties
• Good resistance to hydrocarbons of high aromatic content and water
• Compliant to FDA and 3-A standards

Silicone (VMQ)

Silicone is an extremely versatile material that lends itself to a broad range of application conditions. As a liquid raw material, silicone offers advantages in processing that render it a premier choice of material for technical components where long-term consistency of precision, quality and performance is key. A next generation of low volatile liquid silicone rubber (LSR) materials is bringing exciting, new advantages in processing and application capabilities.

Other characteristics are:

• Good chemical resistance in a wide range of media
• Excellent heat resistance, dielectric strength and cold flexibility
• Neutral in taste and odor
• Good electrical and mechanical dampening properties
• Excellent weather and UV resistance, hydrophobic
• Sterilizable: γ-radiation, steam, EtO
• Biocompatibility – non-allergenic
• Approvals and compliances to WRAS, KTW, NSF and more.

We offer extensive silicone processing, including extrusion, injection, transfer or compression molding and sheeting, as well as state-of-the-art LSR injection molding, with cleanrooms to meet special cleanliness demands.
