COC 5013L-10 高透明耐化学 (CAS No.None)

Product Name:COC 5013L-10 High Transparency Chemical Resistant

English Name:COC 5013L-10 High Transparency Chemical Resistant

CAS No.:26007-43-2

Aliases:Cyclic Olefin Copolymer, Cycloolefin Copolymer, COC Resin, Ethylene-Norbornene Copolymer

Molecular Formula:(C9H14)n

Physical Properties:Amorphous transparent resin with low density, approximately 10% lower than PMMA and PC, facilitating lightweight products; low saturated water absorption, far lower than PMMA, with no property degradation caused by moisture uptake; low birefringence. High heat resistance with glass transition temperature of 140–170°C; excellent mechanical properties with tensile strength and elastic modulus higher than PC; low dielectric constant and superior high-frequency dielectric performance; good scratch resistance with pencil hardness similar to PMMA; good adhesion to inorganic and organic materials, easy to seal. Easy injection molding with excellent replication, yielding high-quality products.

Uses:Mainly used in optical lenses, optical pickups, polygon mirrors, touch panel protective films, DVD disc substrates, backlight light guide plates for large displays, and front light guide plates for small displays. It is also suitable for optical semiconductors, optical fibers, and cells/cuvettes for analytical chemical instruments.

Technical Specifications:

Density is approximately 10% lower than PMMA and PC, beneficial for product weight reduction.
