What is COC film?
Cyclic olefin copolymer (COC) is an amorphous thermoplastic that enables higher performance in multilayer polyolefin packaging films for medical, consumer, and industrial markets.
What is COC plastic?
COC (cyclic olefin copolymer) is an engineering plastic that is Springboard uses to manufacture a wide range of injection molded parts. COC offers a broad spectrum of desirable characteristics, including: Good melt flowability. Excellent moisture, heat, and chemical resistance. High clarity and low birefringence.
Is COC amorphous?
Unlike other polyolefins, COC is an amorphous polymer. This gives it processing characteristics similar to widely used medical resins such as PC and PMMA. It can be injection molded, and also makes its way into extruded medical film products such as blister packaging and barrier pouches.

Is polyethylene a polyolefin?
Polyolefins are a family of polyethylene and polypropylene thermoplastics. They are produced mainly from oil and natural gas by a process of polymerisation of ethylene and propylene respectively. Their versatility has made them one of the most popular plastics in use today.
What is Topas material?
TOPAS® COC medical polymer is a high quality, highly pure amorphous cyclic olefin resin made by our high purity metallocene catalyst technique and used in medical applications by leading medical firms worldwide. Prefilled TOPAS® COC syringes and delivery devices are increasingly used in place of glass.
What COC means?
Certificate of Conformity
A Certificate of Conformity (CoC), also known as a Certificate of Conformance or Certificate of Compliance is document given to exporters or importers to show that the good or services bought or supplied meet the required standards. The document is usually required during customs clearance of goods to some countries.
What is Topas COC?
TOPAS® COC medical polymer is a high quality, highly pure amorphous cyclic olefin resin made by our high purity metallocene catalyst technique and used in medical applications by leading medical firms worldwide. Drug Delivery. Prefilled TOPAS® COC syringes and delivery devices are increasingly used in place of glass.
What is COP resin?
COP (cyclo olefin polymer) is a specialty resin with a wide range of high-end characteristics, including: Superior moldability. Low birefringence. High transparency. High heat resistance.
Which is better polyolefin or polyethylene?
Polyolefin are polymer materials made from small alkene monomers. Polyethylene is a good example for polyolefin. The difference between polyolefin and polyethylene is that polyolefin is made from the polymerization of alkenes whereas polyethylene is made from the polymerization of ethylene molecules.
Is polyethylene or polypropylene stronger?
Polyethylene has a lower melting point compared to the higher melting point of polypropylene. (this may be a good test for you) Polypropylene is stiffer and resistant to chemicals and organic solvents compared to polyethylene. Polypropylene is pure, non-stretching and generally more rigid than polyethylene.
What can cyclic olefin copolymers be used for?
This newer material is used in a wide variety of applications including packaging films, lenses, vials, displays, and medical devices. Cyclic olefin copolymers (COC) can provide moisture barriers to blister packs, typically in multilayered combinations with polypropylene (PP), polyethylene (PE), or glycol-modified polyethylene terephthalate (PETg).
Is it safe to use TOPAS cyclic olefin polymer?
TOPAS cyclic olefin polymer is unaffected by moisture, and because most grades are 100% amorphous, dimensional accuracy is not affected by crystallization as many olefin and non-olefin plastics can be. When precise and consistent performance is essential, TOPAS COC is the safe choice for tight tolerances.
What kind of materials are cycloolefin polymers made of?
Cycloolefin polymers are materials that contain, or are made from, at least one cyclic monomer. The term is most often used to refer to cyclic olefin polymers and copolymers.
Which is the chemical cousin of cyclic olefin?
COC is a chemical cousin of another amorphous polyolefin, known as COP (cyclic olefin polymer). This resin shares many high-performance attributes with COC and is used in many of the same applications, with each having minor advantages in certain performance categories.
