Cyclic Olefin Copolymer<br />

Cyclic Olefin Copolymers are high transparency, low specific gravity, high heat<br />

resistant and have excellent optical properties and superior water vapor barrier<br />

characteristics . Combined with outstanding stiffness / strength and favorable<br />

sterilization properties, they have found applications ranging from FDA approvals<br />

for pharmaceutical and food applications to optical applications and electronics<br />

materials . Whether used by itself or as a modifier for other resins, the ethylene-norbornene<br />

copolymer offers the optical clarity of polymethylmethacryate (pMMA),<br />

the heat resistance of polycarbonate (PC) and superior dimensional stability .<br />

Properties:<br />

• High transparency<br />

• Outstanding moisture barrier<br />

• High rigidity and strength<br />

• Variable heat distortion resistance up to 170°C<br />

• Excellent biocompatibility<br />

• Very good resistance to acids and alkalis and polar organic solvents<br />

• Low density<br />

• Very good electrical insulation properties<br />

• Exceptionally low moisture absorption<br />

• Low birefringence<br />
