Cyclic Olefin Copolymer, HDT= 75°C

(Ethylene-Norbornene Copolymer)

HDT = 75°C
Tg = 80°C
Density: 1.02

Cyclic Olefin Copolymers are high transparency, low specific gravity, high heat resistant and have excellent optical properties and superior water vapor barrier characteristics. Combined with outstanding stiffness/ strength and favorable sterilization properties, they have found applications ranging from FDA approvals for pharmaceutical and food applications to optical applications and electronics materials. Whether used by itself or as a modifier for other resins, the ethylene-norbornene copolymer offers the optical clarity of polymethylmethacryate (pMMA), the heat resistance of polycarbonate (PC) and superior dimensional stability.
Applications:

Pharmaceutical, medical device and personal care blister packaging
Flexible films for food and healthcare industry
Prefillable syringes, vials, ampoules and other pharmaceutical packaging components
