KURARITY are novel (Meth)acrylic TPEs that have block structures like PMMA-b-PnBA-b-PMMA. Kuraray has pilot plant of KURARITY in Japan and started limited marketing now.

Kuraray announces that it recently decided on the brand name "KURARITY" for its new acrylic thermoplastic elastomer (development name: "LA Polymer"), the full-scale business development of which the Company had made public in March 2010.

There are several grades from sticky softest grade to tough and rigid grade. All grades and their blends have excellent transparency and wheater-ability like PMMA resin. So we called them “flexible PMMA” . Other characteristics of KURARITY are low melt viscosity, good adhesion to polar plastics like PMMA,PC,ABS etc, and good paint-ability.

Possible applications of KURARITY and their compounds are follows:

1) injection molding especially 2K-moulded soft parts like grips for IT devices, home appliances and Automotive interior parts.

2) flexible and transparent films with small patterns for optical devices.

3) hot melt or high solid acrylic based pressure sensitive adhesives.

4) additives for very flexible Polylacticacid (PLLA) alloy and other impact modifiers of PMMA, PC, PBT etc.

Methacrylic resin has the highest transparency and weather resistance of any plastic. These characteristics make it suitable for use in light -guide plates for liquid crystal displays (LCDs), automobile lamp covers, and lighting fixtures.

EVAL is a high-performance resin that boasts excellent gas-barrier properties. It is suitable as a packaging material not only for mayonnaise, ketchup, and a wide range of foods available in retort pouches, but also for cosmetics and pharmaceuticals, because it shuts out oxygen, thereby protecting the contents against deterioration and degradation. By showing its effectiveness in preventing leakage of evaporated hydrocarbons in automobile plastic fuel tanks, we have opened up new areas of demand.

Exceval is a chlorine free gas barrier material specially designed for the flexible film packaging industry.

This novel ethylene modified polyvinyl alcohol copolymer is completely water soluble and shows outstanding oxygen barrier performance even at high degree of relative humidity.

Furthermore the Exceval waterborne coatings are highly transparent and glossy and show a strong chemical resistance as well as a good printability.

With Mowiol, Kuraray Poval and Exceval Kuraray offers water soluble polymers providing a superior grease and solvent barrier without the use of fluorinated compounds. These polymers give clear and absolutely transparent flexible films which can be applied via a wide range of coating systems (size press, metering size press, curtain coater, reverse gravure roll, ...). Most grades have FDA and/or BfR approval.

Unique man-made polymer which can be extruded, dye-cast, solution casted (dissolved in water; no other solvents needed) or even injection moulded. Next to being water soluble the Mowiol and Kuraray Poval are providing a superior gas barrier to gases like oxygen, nitrogen, carbon dioxide and others. Clear and absolutely transparent films and containers can be made providing also excellent barriers toward aromas and odours.

Consisting solely of carbon, hydrogen and oxygen polyvinyl alcohol (Mowiol and Kuraray Poval) are water-soluble polymers which biodegrade in aqueous environment.

Kuraray offers new polymer compounds especially designed for the requirements of thermoplastic processing. The new water soluble (Mowiol / Kuraray Poval) polyvinyl alcohol-based compounds are non-toxic and can be processed by standard thermoplastic technologies like blown film extrusion, etc.. Thanks to their low melting temperature and excellent flow qualities, the new (Mowital) polyvinyl-butyral based compounds are easy to use, for example, in injection moulding processes at temperatures ranging from 130 °C to 280 °C. Your idea is our task!

®Mowiflex TC is a novel thermoplastic compound, especially designed to meet the requirements of thermoplastic processing. It can be processed using conventional plastic processing technology, such as blown and flat film extrusion as well as injection moulding. At the same time, ®Mowiflex TC has all the advantageous properties of polyvinyl alcohol (PVA): It is soluble in water, forms clear and glossy films and shows high tensile strength. ®Mowiflex TC can be processed as a single compound or as an additive to standard plastics such as PA and it allows for blow up ratios of up to 1:8. In contrast to PVA, it does not have to be pre-treated before thermoplastic processing. It is delivered as a ready-to-use product containing all the ingredients needed. The properties of the ®Mowiflex TC compound can be well adjusted to the requirements of the desired application. Materials produced with ®Mowiflex TC provide excellent weldability and bonding, are easily printable and have a low electrostatic surface charge. Additionally, the compound is colourable, which makes it possible to process ®Mowiflex TC as a highly concentrated masterbatch. Due to its excellent water solubility, ®Mowiflex TC can be used as a temporary binder as well.

SEPTON is a series of high performance thermoplastic rubbers (TPE) developed by KURARAY CO., LTD. using its unique isoprene technology. In terms of structure, SEPTON is a series of hydrogenated styrenic block copolymers(SEP ,SEPS ,SEEPS , SEBS), and it exhibits rubber-like properties over a wide range of temperatures. Its remarkable characteristics are as follows:

- Excellent Mechanical Properties

- Good Weatherability

- Excellent Low Temperature Properties

- Excellent Electrical Insulation Properties

- Superior Heat Resistance

- Excellent Chemical Resistance

- Low Toxity

Prior to processing, the polystyrene end blocks are associated in rigid domains. In the presence of heat and shear such as during processing, the polystyrene domains soften and permits flow. After cooling, the polystyrene domains reform and harden, locking the rubber network in place. This physical phenomenon provides SEPTON with its high tensile strength and its elasticity. Since SEPTON is a thermoplastic, it is recyclable.

Based on 20 years of experience in the field of elastomeric block-co-polymers Kuraray developed a new material with remarkable characteristics. The new material is available as neat polymer - Septon Q series. Moreover an alloy technology applied onto this new material generates a novel class of TPE which enters the application areas of TPAE, TPEE and TPU. The alloys show advantageous processing properties and good performance in combination with polyolefins.

The new material first was presented under the name Q-Polymer. It comes now to markets under the brand name Septon Q series. Its outstanding performance can be generated with Kuraray's own alloy technology that creates light and scratch resistant materials. These alloys work well together with various polyolefins.

The first commercial application after setting up the new material was in specialized soccer shoes. In this shoe sole a very good abrasion resistance is combined with the advantage of a light weight material. TPU shows a specific gravity level of 1.2 vs. 0.9 roughly for the Septon Q series alloy.

Kuraray Co.Ltd.has thus far developed and marketed the SEPTON™ V Series and the SEPTON™ Q Series within its SEPTON™ and HYBRAR™ families of high-performance, highly functional thermoplastic elastomer products.To enhance and reinforce its lineup, Kuraray has now developed the SEPTON™ K Series which features superior bondability to glass and metal.

Like a number of other plastic products, SEPTON™ and HYBRAR™ hydrogenated styrenic thermoplastic elastomers can be easily molded; however, they are also characterized by rubber-like elasticity and are widely replacing vulcanized rubber as a soft molding material. Combining Kuraray's accumulated polymer synthesizing technologies and alloy technologies, the newly developed SEPTON™ K Series material represents a new concept in elastomeric materials. Existing products require pretreatment with primer to obtain the bondability needed for use on glass and metal. However, the SEPTON™ K Series can be directly injection molded or extruded onto glass or metal without pretreatment, achieving excellent bondability while retaining the advantages of a thermoplastic elastomer. Thanks to its excellent bondability the SEPTON™ K Series is a revolutionary molding material that enables faster production and a high degree of freedom in product design, particularly in such fields as automotive, electric and electronics, and other glass-related components. Pursuing further advances in product and market development, Kuraray expects this product to enter the film, sealant, coating and adhesive fields.

Unique man-made polymer which can be extruded, dye-cast, solution casted (dissolved in water; no solvents needed) or even injection moulded. Next to being water soluble the Mowiol and Kuraray Poval are providing a superior gas barrier to gases like oxygen, nitrogen, carbon dioxide and others. Clear and absolutely transparent films and containers can be made providing also excellent barriers toward aromas and odours.

Under the trademark Mowital, Kuraray Europe (KEG) markets a wide range of different polyvinyl butyrals. Mowital has excellent adhesion and film-forming properties, high binding power and outstanding optical transparency. In addition, it is soluble in many organic solvents and can be combined with many different resins and reaction partners.

Thanks to its excellent thermoplastic properties Mowital can be used in standard plastics procedures such as extrusion and injection moulding. It is also an essential constituent of lightfast, highly transparent, elastic and tear-proof films. When pressed between two panes of glass it creates fracture-resistant and shatterproof laminated safety glass used mainly in the building and automobile industries.

Kuraray has developed polyvinyl alcohol-based suspending and anti dry-foaming agents especially for the needs of PVC manufacturers. In these applications polyvinyl alcohol is used as a protective colloid for the polymerisation of PVC. Kuraray’s primary and secondary suspending agents permit precise control of the grain formation and of the suspension of PVC particles. Particularly the L-Series grades make it possible to precisely control the resulting structure and morphology. Furthermore, the surface active performance can be widely optimised by selecting an appropriate combination of Kuraray’s suspending agents from the LM-Series. Kuraray’s secondary suspending agents (LM polymer) improve the porosity of systems based on Kuraray’s primary suspending agents. In addition to particle size and morphology the porosity is a decisive factor in the ability to absorb plasticizers. Furthermore, Kuraray’s products enable one to accurately control additional parameters, such as: o Charge size o Cycle times in high speed mixers o Output rates
