Techpolymer (optical use)

To provide acrylic, PET, and polycarbonate resins with the property of diffusing light

Techpolymer is a light diffusion agent which provides superior light transmittance and diffusion performance.

Sekisui's Techpolymer is an indispensable part of the LCD for personal computers and televisions. The uniform light diffusion effect from the spherical particles helps make the entire display brighter and easier to see. It is also used as LED light cover's light diffusion material. It can be used in the fields that require high optical performance by reducing all light transmittance with haze-boosting effects. Upon customer request, we are developing varieties with improved optical performance and solvent resistance.

Specific applications

Techpolymer is used as a light diffusing material to scatter transmitted light and reduce reflected light, being added to transparent resins such as acrylic resin and polycarbonate resin, and also being coated on the surface of transparent films such as PET film. Compared to generally-used, non-organic titanium oxide, barium sulfate, and others, Techpolymer boasts higher light transmission and lower loss of all light transmittance, as well as the haze-boosting effects.

Piocelan distribution container for flat-panel television co

Distribution container for glass and panel for LCD/PDP television sets

This material protects LCD and PDP components with its superior shock-absorption performance and all-dimension stability.

Due to its excellent shock-absorbing performance and all-dimension stability, the use of Piocelan has expanded to distribution of large-sized digital consumer electronics products.

Distribution container for large-sized flat television panels

This container is suitable for transportation of LCD and PDP panels. It can hold up to 20 to 50 panels at a time. The returnable container's measurement precision is high, and it is light-weight.

Distribution container for large-sized glass

This container is suitable for transportation of PDP glass, color filters, and cells. Using Piocelan's superior features, it can be formed up to the size of 2,360mm×1,050mm×H2,100mm. The container's measurement precision is high, and its compression and bending strengths are also high.

Seat core material

Insert forming with urethane foam is possible.

Seat core material

By using the material as rear seat cushion, metal wire parts are drastically reduced, resulting in light weight of seats. At the same time, with its excellent impact absorption performance, the seat core material contributes to the protection of drivers and passengers by preventing the sinking of seats at the time of impact.
