COMPANY

MY Polymers - The Low Refractive Index company

Distinguished by its total focus on low Refractive Index (RI=1.30 to 1.50) coatings, adhesives, and polymers, MY Polymers is a leader in this field.

Our products include low refractive index primary coatings (cladding resins), which are used in the manufacturing of specialty optical fibers.

Our recoating materials are used for recoating splices, combiners, and other components where there is a need to recoat a splice or a stripped section of an optical fiber. Our low index of refraction recoatings was designed for both recoaters and manual recoating. The viscosity is optimized for recoaters, enabling high-quality smooth molds. Our recoating materials are used by manufacturers of fiber lasers and sub-systems and components of fiber lasers.

Other major fields of application for our low index of refraction materials include electronic displays and bio-photonics systems and devices. Our low refractive index resins are based on the proprietary resins that we synthesize from raw materials.

MY Polymers is ISO certified by The Standards Institute of Israel, SII – A founding member of ISO and the country’s quality leader. Click to see our ISO CERTIFICATE.

We are working continuously to improve our customer support.

Recently, we began to offer a degree of cure measurements for customers who want to evaluate our primary coatings or wish to analyze the impact of introducing a change in the parameters of their specialty optical fibers drawing process.
Our products are sold in South Korea, Canada, the US, Europe, Japan, China, Taiwan, Singapore, and Israel.

Our customers include manufacturers of specialty optical fiber; Fiber laser manufacturers; fiber-optic components suppliers; manufacturers of optical amplifiers; electronic display manufacturers; and about 200 companies and institutes that use our products in a wide range of applications covering (to name but a few) SPR Biosensors; Micro-fluidics; Microscopy calibration targets; Automotive instrumentation panel backlights; Optical security of documents; Light engines; and 3D displays.

MAJOR PRODUCT CATEGORIES

Optical Fiber Coatings and Recoating Materials

The OF series of UV-Cured Cladding resins for the primary coating of specialty optical fibers. Our popular OF-136 is used by the majority of leading manufacturers of specialty optical fibers. Our OF-133 enables the production of optical fibers with a break-through Numerical Aperture of 0.59. And the OF-138, OF-139-N, and OF-140-N are used in applications that require very high modulus and very high adhesion to the core. OF-136 and most of our other primary coatings include our proprietary adhesion promoter that improves adhesion to the fiber core, especially under wet conditions.


The largest selection of dedicated, optimized, recoating materials

About 7 years ago MY Polymers decided to design specially optimized recoating materials, dedicated to recoating. At that time the practice was (and still is in some companies) to use the primary coatings as the recoating materials. The major disadvantage in this practice is that the requirements for a good recoating material contradict those of a good primary coating. For example – adhesion of a primary coating to the core must be limited, to enable stripping.

Electronic display adhesives​​

Our LOCA adhesives are distinguished by their unique combination of high bond strength AND low refractive index. The LOCA products exhibit strong adhesion to various substrates, including glass, PMMA, PET, PC, and metals.

These adhesives remain tacky even after full curing, and therefore they are intended to be used as lamination adhesives, between optical films and other flat surfaces. The low index enables bonding between layers while keeping the light from leaking between adjacent layers. For example, it is possible to attach a diffuser film to a light guide without degrading the light-guiding capability.

The adhesion of LOCA-133 (index=1.33) is 25-50 times stronger compared to our previous generation of adhesives with the same 1.33 index. MY Polymers believes this breakthrough in the bonding strength of an optical adhesive with an index of 1.33 opens various opportunities, especially in the electronic display market. LOCA-135, with an index of 1.35, is significantly cheaper, compared to LOCA-133. LOCA-133-S1 is a 100% solids (no solvents at all) version of LOCA-133.

LOCA-133 combines a low index of 1.33 AND strong adhesion to various substrates.
LOCA-135 has an index of 1.35. It is a lower-cost version of LOCA-133.

Bio-photonic materials

Our selection of low refractive index polymers, with an index of 1.33, that matches waters and cell tissues enable a wide range of benefits in biophotonics (For example, improved image quality in live-cell imaging in micro-chamber arrays made of a polymer with an index of 1.33 or 1.34).  

BIO-133 and BIO-134 with index 1.33 and 1.34 were designed for minimal cytotoxicity and minimal fluorescence, and are being gradually adopted by more researchers, both in the academy and in pioneering biotech companies.

Recently published academic papers (e.g. Zangle et al) keep demonstrating the significant improvement in imaging, enabled by the low index of refraction of our materials. The 1.33 index is matched to the refractive index of water and cells, resulting in significant improvement and elimination of optical distortions.
