Rare earths

Rare earth products are not directly visible, but they have excellent chemical properties and are used in various areas mainly in electronics. So far, industries have paid attention only to the chemical properties of rare earths, but Shin-Etsu Chemical has taken notice also the physical properties. Using data accumulated over many years and our original process technology, we succeeded to control the size and shape of oxide grains. We now have a complete lineup of products, including spherical ultra-fine particles of 0.1μm.

Rare earth magnets

Rare earth magnets are high performance permanent magnets using rare earths as the raw material, produced by an integrated system that handles all processes from the separation and refinement of rare earth elements to manufacturing of magnets. We supply various kinds of magnets and also support the application and development of various kinds of magnetic circuits.

Single crystal ferrites

Mn-Zn single crystal ferrites are high-quality, high-performance head material free of foreign matter or distortion.

Oxide single crystals (Lithium Tantalate: LT)

Oxide single crystals (LT) are used in SAW devices that filters microwaves and picks up only specific frequencies, which are used in mobile communications devices and TV and VTR tuners. Stable composition crystals are made by controlling the lattice constant. This assures small difference in SAW velocity, which leads to a high yield in device production.

Silicone RTV rubber

Liquid or paste silicone RTV rubber was developed for use in adhesion, coating and potting of electrical or electronic parts.

Silicone gel

Unlike the conventional silicone RTV rubber, this product becomes a gel after curing. After curing, it exhibits superior cold/heat resistance, electrical insulation, and transparency, similar to silicone rubber.

Thermally conductive silicone fluid compounds

This product has heat resistance and electrical characteristics intrinsic to silicone. Moreover, it also has excellent thermally conductive property. By rapidly dissipating the heat generated by various kinds of electronics products, this product prevents heatrelated troubles, and improves the reliability of equipment. Thermally conductive silicone fluid compounds are most suitable for dissipating heat generated from the CPU for personal computers, which requires especially high thermal conductivity.

Thermally conductive silicone rubber products

This series include low hardness type, phase change sheet (PCS) type, and electromagnetic wave absorptive and thermally conductive type, and other types. They are effective for heat dissipation of electronics products.

Heat shrinkable silicone rubber tubing

By heating this silicone rubber tube, the internal diameter contracts easily to one half of its original size. It is used for insulation, protection and covering.

Electrically conductive silicone rubber products

This product has heat resistance and electrical characteristics intrinsic to silicone. Moreover, it also has excellent electrical conductivity. It is most suitable for use as control measure to prevent electromagnetic waves of computer, OA equipment, and medical equipment, as well as static electricity from various electric and electronic equipment.

Pure sealant

Pure sealant is suitable for sealing the joints, space around air filters and piping of clean rooms for semiconductor production processes.

Liquid fluoroelastomers "SHIN-ETSU SIFEL"

SHIN-ETSU SIFEL is a novel fluoroelastomer that revolutionizes the image of conventional fluororubber. In addition to the conventional use for molding, it can be used for sealing, coating and potting of electronic parts, which were unthinkable in the past.

Cyanoresin

The molecular structure of Cyanoresin has cyano groups with high polarity. It forms large dipoles in electric field with high dielectric constant. Two types of Cyanoresin are available; polymer type and plasticizer type.

Shin-Etsu SOLEANA

SOLEANA is a high-performance solvent with a methylene chloride base. Because of the excellent properties of methylenechloride, it is useful for cleaning various electronic equipment, not only playing a role in control quality but also contributing to improve production efficiency.

Shin-Etsu keypad FB type

The FB type is a key pad using a molded film as a surface of key tops. It is available in two types; the key tops and silicone rubber integrated type and the hard key type.

Shin-Etsu keypad AP-I type

The AP-I type is composed of two materials. A highly transparent hard resin key-tops with printing on the back side are bonded to a semitransparent silicone key pad. Incorporation of a PET dome or a metal dome is also possible.

Shin-Etsu keypad PB type

Only the key-top part is made of plastics material, and it is linked to a silicone rubber base.

Shin-Etsu keypad HG type

Only the characters of the key tops transmit light from backside light source. Shin-Etsu Polymer was the first in the world to develop this type of key pads.

Shin-Etsu keypad KTP type

Shin-Etsu key pad is a high-performance part for input, in which the electrically conductive silicone rubber is used as the switching element. Especially, the KTP type has incorporated a key top, and this type integrates the switching function, the spring function, and the operation button function on a single sheet of silicone rubber. The key top-part has printed characters and figures.

Interconnectors for LCD

These interconnectors combine low cost and high reliability, and are used in various displays. An example is an electrically conductive rubber pressure type connector, which can be connected just by inserting between electrodes and apply pressure. Another example is a heat-seal connector with a high degree of freedom in design.

Low-resistance interconnectors

The pressure type connector uses thin metal wires, metal particles, and metal pins. It accomplishes highly reliable low-resistance connection between PCBs and between substrates and parts, and involves a simple assembly process. By using this product, achieves solderless processes and absorbs the dimensional tolerance. By incorporating the frame and holder, the number of parts is reduced, which may lead to a reduction of total costs.

Semiconductor interconnectors for inspection

The anisotropic conductive rubber sheet has thin metal wires arranged at high density. Using this conductor, devices with electrodes arranged in narrow pitches, such as a flip chips, can be connected simply and reliably. Due to its low inductance, the connector does not affect the performance of RF-IC and highfrequency electronic parts.

Shin-Etsu PP films type R

It is a dielectric material for capacitors, manufactured by the simultaneous biaxial-stretching method using inflation method. It contributes to improve the reliability and compactness of capacitors for super-high voltage. It is used also for the all-film capacitor with single capacity of 30 Mvar, the highest in the world.

NEW FPC(Flexible Printed Circuit Board)
High Speed Flexural Endurance Tester

This instrument can test the flexural endurance of FPC films at high speeds of up to 3000 cycles/ min, for 108 flexural cycles or more. Multiple film samples(max,8pcs)can be tested simultaneously. A special structure vibrator that converts frequency into a direct, reciprocating motion was utilized in developing this high-speed reciprocating flexural endurance tester. Compared with conventional models, the new models have realized a higher level of functions by employing personal computer as a standard model and more compactness.
