Sekisui Chemical Expands Foamed Polyolefin Capabilities
LAWRENCE, MA (December 9, 2002) – Sekisui Chemical Co., LTD, parent company to VOLTEK, Division of Sekisui America Corporation, announced the acquisition of management rights to the largest foamed polyolefin manufacturer in China, Shanghai Holy Plastics, LTD. With production bases in Japan, United States, Europe and Asia, the addition of Shanghai Holy Plastics will heighten the ability of Sekisui Chemical Co., Ltd. to compete on a global scale.
The present demand for foamed polyolefins in the Chinese market is about 3,000 ton a year. However, there is expected to be a significant increase in demand due to progressive entries of automotive companies, China’s participation in the WTO, the Beijing Olympic Games, 2008, and a building boom for the Expo 2010 in Shanghai. Within this growing market, Sekisui Chemical will establish an advantageous position at an early stage, by combining high level technologies and sales know-how.
In addition, Sekisui Chemical will enhance its globally competitive strength by being able to supply customers from many locations worldwide, improving responsiveness to global demand, and offering customers more flexibility in supply.
Voltek Announces Plans to Exhibit at Medical Design & Manufacturing West 2003, Conference & Exhibition
LAWRENCE, MA (December 2002) – VOLTEK, Division of Sekisui America Corporation has announced plans to exhibit at the Medical Design & Manufacturing West 2003 (MD&M 2003) in Anaheim, California from February 19 – 21, 2003. For the past two years, Voltek has joined other companies participating at this event.
For 2003, Voltek will be displaying new products and capabilities recently developed for the medical market. The products include the following:
Voltek has made significant manufacturing improvements to both Volara and Minicel.
Volara 4 – 6 pcf foams can be manufactured widths great than 80″ wide. The wide width will allow customers with secondary processing equipment to utilize their machinery to the fullest capabilities.
Minice bun foams can be manufactured at a thickness of 4″. All resin types and colors that are currently produced at a 3″ thickness are now available at 4″. The following densities are available: 1.5, 1.7, 2.25, 2.5, 2.85, 3.2 and 6.5 pcf.
Volara HPT: A high performance irradiated crosslinked closed-cell polyolefin foam. Volara HPT offers the tightest gauge and density control in the industry. Volara HPT .012″ is the thinnest foam manufactured in North America. Precise thickness control means that roll lengths of 4500 feet without gauge banding can be produced.
Volara G: Volara G foams are derived from ethylene copolymers that make them ultra soft and conformable. Manufactured with Voltek’s propriety technology, Volara G foams are not stretched or compressed during the process. The properties of Volara G make it an ideal substrate for wound care, finger bandages, transdermal drug patches, ostomy seals, and electro-medical devices. The favorable economics of polyolefin foams make Volara G a suitable replacement for flexible PVC, urethanes, films, and nonwovens.
Volextra HM: Volara HM is an irradiated crosslinked closed-cell polyolefin foam with a polyethyleneterephthalate(PET) film. By laminating a PET film to Volara, it produces a product with extremely high X-Y modulus. The result is a very mechanically stable substrate that is also tough but conformable. With these dimensionally stable features, Volara HM offers very high rotary die cutting rates without part deformation. The surface is smooth and printable.
Volextra LL: Volextra LL was developed with the concept of thin coatings on thin foams. Volextra LL combines Volara crosslinked foams with a specially formulated linear low density polyethylene extrusion coating. The coatings add functionality and esthetics to Volara foams and can be applied to one or both sides of the foam. In addition, the coatings improve toughness, coefficient of friction, color, texture, abrasion, and molding performance.
Minicel S: Compared with traditional cross-linked polyolefin bun foams, Minicel S has superior resistance to permanent set, is more resilient, possesses high coefficient of friction, and is softer at higher densities. This last feature permits the use of high density foams with their better physical properties while maintaining softness and conformability.
Minicel Two Tone: This product is a combination of two colors that results in a swirled pattern so that each individual color is visible in the product. The Two-Tone product is available in all grades and sizes that are currently available in all Minicel products.
Voltek Introduces New Volara HPT High-Performance Cross-linked Thin Foam
LAWRENCE, MA (May 3, 2002) – VOLTEK, Division of Sekisui America Corporation, has introduced a new line of high-performance radiation, cross-linked, polyolefin foams. The Volara HPT foams rely on advanced extrusion, cross-linking and foaming processes to achieve the tightest gauge and density control in the industry. At 0.012 inches, Volara HPT is the thinnest cross-linked foam manufactured in North America.
The extreme toughness of Volara HPT thin foams makes them ideal for low profile mounting applications, such as mirrors, emblems and applications. Thicker HPT foams can replace screws, rivets, pumpable (caulk) adhesives, as well as more costly urethane and acrylic foams, in a variety of assembly applications. Other uses include manufacturing of electro-medical devices, transdermal drug delivery, and gasketing.
Precise thickness control means that roll lengths of 4,500 feet can be produced without gauge banding. The result is fewer roll changes for converters and a better match to release liner roll lengths. Absence of gauge bands also eliminates puddling of adhesives during direct coating processes.
Low gauge variation allows manufacturers of flexo-graphic cushion mount tapes, who employ a secondary converting process, to reduce process time and scrap. Additional savings can be realized if more than one thickness is produced. For example, it is common practice to purchase thick foam that is then converted to produce two mounting tapes of different thickness (i.e., 0.0017 inches and 0.0022 inches). With Volara HPT, a thinner, less expensive grade can be purchased for making a thinner end product.
The HPT line ranges in thickness from 0.012 to 0.075 inches. Densities are available from eight to twenty pounds per cubic foot. Standard widths are 56 and 60 inches, and custom widths are available. HPT rolls are packaged for ease of handling and to eliminate damage during shipment. HPT foams are available in standard and custom colors.
