U polymer

U polymer is a super engineering plastic commercialized by UNITIKA in advance to any other companies in the world. With its excellent properties, U polymer is used in a variety of applications including precision devices, automobiles, machines, medical devices, foods, and daily commodities. UNITIKA is also developing various other grades that satisfy the specific needs of customers by applying the favorable properties of the polyarylate resin (U polymer) developed with all technical resources of UNITIKA and using the UNITIKA's proprietary compounding technology.


Transparency and heat resistance U polymer has the highest-level heat resistance among transparent resins available (deflection temperature under load: 1.8 MPa at 175°C) and the transparency as high as PC or PMMA, transmitting almost 90% light.
Elastic recovery U polymer exhibits excellent elastic recovery, and has a high allowable strain ratio and thus may be used as springs in a wider range of length. U polymer is also excellent in creep properties and retains the properties as spring for an extended period of time.
Weather Resistance Because UV irradiation increases the UV-blocking property of U polymer, U polymer exhibits excellent weather resistance without addition of any additives for improving weather resistance. (Although there is some yellowing, there is almost no change in physical properties, transparency, or others.)
Flame resistance U polymer is approved as UL94 V-2 (0.75 mm) without addition of any flame retardants. (Standard grade)

UNILATE® products are plate materials prepared by using a polyethylene terephthalate (PET resin) as the main component, blending it with glass staple fiber, inorganic filler, and others, and extruding the composite resins into plates, and laminating and heat-pressing the plates. UNILATE plates and boards are superior in heat resistance, withstand voltage, strength, and processability to the plates and boards of thermoplastic resins such as nylon, polyacetal, and others. The UNILATE plates and boards are greatly improved in water-absorbing property, electrical properties, and processability, compared to other thermosetting resin laminated sheets used in electric insulation applications.

UNITIKA nonocomposite nylons, reflecting the unique structure above, have the following characteristics

Low density and high-rigidity The nanocomposite nylon resins have about twice greater rigidity than the nonreinforced nylon 6 resins, although their densities are similar.
Low opacifying property, surface smoothness, and glossiness Nanocomposite nylon resins are superior in appearance and surface smoothness, as they only contain small amount of minerals but no glass.
Water-absorbing property The water-absorbing speed and thus the dimensional change of nanocomposite nylon resins are smaller than general nylon resins, as nanocomposite nylon resins have higher crystallinity.
Moldability Nanocomposite nylon resins are excellent in flowability and mold replication and allow high-cycle molding, as the resins crystallize very rapidly.

Unitika's History Creates its Next History

The Unitika Group got its start in 1889, with the founding of Amagasaki Spinners, a historic first step in the start of Japan's textile industry. When the company changed its name to Dainippon Spinners in 1918, it was already helping to support the Japanese fiber industry as one of Japan's three largest textile makers. In 1969, the company merged with Nippon Rayon and the new company became known as Unitika. Today, Unitika's fiber and textile business and the dynamic array of its other business activities are made possible by the interactions among all the Group members. As Unitika continues to evolve into the future, its wealth of experience is an asset shared throughout the Group.
