COC

Cyclic olefin copolymer

COC is a glass-clear amorphous olefin with a high moisture barrier and no moisture uptake; low density and dimensional stability make it stand out in optical and medical parts. The ethylene–norbornene ratio tunes the glass transition between 70 and 180 °C. Uses include syringes, blister film, optical lenses and microfluidic chips.

Overview

COC is the standard grade of the COC family in the general-purpose plastics group. It is used in applications such as pre-filled syringes and vials, pharmaceutical blister film, optical lenses and light guides. The grade with the right flow for injection, extrusion or another process is specified in the quotation together with your quantity and colour; TDS and SDS are sent with the quotation.

Tensile strength is measured to ISO 527, melt flow rate to ISO 1133, heat deflection temperature to ISO 75 (1.8 MPa); flammability class per UL94. Depending on supplier and grade, values can fall outside this range.

Applications

  • Pre-filled syringes and vials
  • Pharmaceutical blister film
  • Optical lenses and light guides
  • Microfluidic and diagnostic chips

Documents

The supplier's technical data sheet (TDS) and safety data sheet (SDS) for COC are sent by e-mail with the quoted grade; because the same code has different sheets at different suppliers we do not publish a single file on the site. To see the sheet in advance, request it with the link below.
