World's softest polyolefin foam now UL listed
Sekisui Alveo has further expanded its product range of flame-retardant foams: With Alveosoft SA CMU 005, the manufacturer of polyolefin foams now offers its unique Alveosoft crosslinked polyolefin foam in a grade that is UL (Underwriters Laboratories) certified. That’s good news for OEMs that require UL listing of the plastic components and materials like sealing gaskets they use in their electronical devices, white goods and industrial components.
Highest horizontal flame-resistance rating
Sekisui Alveo offers its well-known Alveosoft foam in a wide range of types and grades in order to cover a broad variety of different applications and requirements. The latest addition to the portfolio is Alveosoft SA CMU 005, which is UL certified for flame resistance. In horizontal burning tests for foams, test samples with a minimum thickness of 5 mm passed with the highest rating (HF-1). The material is now listed in the UL 94 certification directory. Many OEMs require UL listing of the plastic components they use in their products in order to ensure fire safety.
First-choice sealing material
Alveosoft is the world’s softest polyolefin foam and is well known as a unique solution in the market. Its excellent air sealing characteristics at low clamping forces far outperform those of PUR and PVC foams. That’s a key reason the material has become the first choice for many sealing applications and as an acoustic or thermal insulation solution.
New foam types for lightweight vacuum-formed automobile components
Sekisui Alveo has further expanded its product range: With Alveolen NLC LV & NLT LV, the manufacturer of polyolefin foams now offers two new foam types designed specifically for vacuum-forming parts. The new Alveolen NLC LV 1404.5 and NLT LV 1404 foams are ideal for vacuum forming automobile components like air ducts, cold air covers, headliner ducts, and seat belt covers.
Both products have been proven in serial production in the car industry; Alveolen NLC LV is used for making air ducts for the Tesla Model X electric vehicle – the world’s most innovative SUV.
Evalen portfolio expanded
Sekisui Alveo has recently expanded its Evalen product line. The new products are Evalen Light and Evalen Extra. Evalen combines the advantages of EVA batch foam and Alveolen roll foams.
Evalen foams are an alternative to batch-foam-based materials in continuous production processes. The advantages are zero defects (perfect surface with no pinholes), no butt welding lines, and totally homogenous material performance. The new soft-touch foams with a non-shining surface are press formable, do not contain plasticizers, and feature low water absorption.
Evalen foams are especially suited for continuous conversion processes where scrap reduction, constant quality, optical and haptic requirements, and high overall performance are important.
New wide foam portfolio
Sekisui Alveo has recently invested in new extrusion, crosslinking, and foaming oven equipment, and is now pushing the width limits to a new standard for vertically foamed polyolefin foams. The most common PP foam grades for the automotive industry used to be available at widths up to 2.0 meters. For productivity reasons, the current trend in all markets is toward wider semi-finished roll products.
Sekisui Alveo can now offer its product portfolio of vertically foamed, physically crosslinked PP and PE foams at widths up to 2.5 metres, on request, and depending on thickness and density.
Alveosport - Horizontal drainage system makes Alveosport elastic shock pad even more effective
Sekisui Alveo is expanding its portfolio and is now offering its elastic shock pad Alveosport also with increased drainage capacity. With Alveosport “Horizontal Drainage” (HD) water can be carried off even faster. The technical layer thereby significantly supports faster drying and can be used in rainy regions.
Alveoflooring - Marketing concepts for retailers and do-it-yourself stores
For over 25 years, Sekisui Alveo has been producing various underlays for parquet, LVT, and laminate floors – underlays with outstanding technical properties. The manufacturer of polyolefin foams has now developed a marketing concept under the new umbrella brand name “AlveoFlooring” that will support sales through both retail and DIY channels.
Rigid foam boards with great potential for weight reduction in the automotive and packaging industries
Sekisui Alveo further expands its product range: With Alveocel LP F, the manufacturer of polyolefin foams now also offers rigid foam boards, which will be used mainly in the automotive branch and in the packaging industry. This version of the closed-cell PP foam is produced at a density of 200 to 600 kilogrammes per cubic metre. The rigid foam boards, from one to five millimetres thick, are 50 to 70 percent lighter than e.g. injection-moulded solid plastics used in comparable applications. Thus, the rigid foam is interesting as a lightweight solution for various industries.
Alveocel used as acoustic solution in new sports car
Sekisui Alveo recently helped an OEM find an efficient acoustic solution for the floor pan of a new sports car - just a few weeks before production of the car was scheduled to start. The flat absorber made of Alveocel PP foam provides excellent noise-absorption properties.
