Volara® Automotive Foam Grades
Last week was “Race Week” here in Michigan, and we are spotlighting how and where SEKSIUI Voltek’s Volara® foam is used within the automotive market. Our product range includes an assortment of polyethylene and polypropylene foams designed specifically to meet the needs of the global automotive industry.
We manufacture Volara foam using our proprietary irradiation cross-linked process, providing a closed-cell, cross-linked foam product available in various densities, resin mixes, thicknesses, widths and colors. Volara is a versatile foam option because of its lightweight, smooth surface and low water absorption. Additionally, it is also ideal for sound dampening and insulation purposes. If your application requires FR or anti-microbial properties, special additives are available to meet your needs.
Popular Automotive Foam Grades
- Type AS – Polyethylene blend for enhanced vacuum forming capabilities. For applications required to pass FMVSS 302, FR can be added.
- Type AF – General purpose LDPE foam with certain fire retardant properties and a great choice for automotive components. Meets certain federal, military, and automotive requirements on the flammability of cellular plastics.
- Type LS, LSO – Rigid polypropylene alloy with improved thermal stability and ideal for thermoformed component applications.
- Type RS – Custom-made polypropylene alloy variants for automotive interior trim, high heat resistance, high elongation.
- Type SVS – A soft polypropylene foam with very good recovery characteristics ideal for interior trim applications.
- Type VS, VSO, VSX – Custom-made polypropylene alloy variants for automotive interior trim, high heat resistance, high elongation.
Volextra combines the superior properties of Volara with the added benefit of extrusion coatings added to one side, both sides, or between layers of Volara foam. Volextra also provides enhanced performance, processing and decorative features to meet surface and structural requirements with a lightweight foam material.
- Surface coatings – LDPE, LLDPE, HDPE, EVA, PP, TPO, TPR, SURLYN, FR, UV inhibitors, anti-static
- Coating range – 2 mils to 55 mils thick, depending on coating resin
- Surface finish – leather grain, burlap, glossy or matte
- Thickness – 0.031″ to 2″ laminated
- Foam Density – 2-12 pcf, all Volara grades

History of SEKISUI Voltek and Volara® Foam
SEKISUI Voltek’s closed cell, cross-linked polyolefin Volara® foam has grown to become a widely recognized brand of foam. Volara is found in many everyday applications for the transportation, medical and general industrial markets. As one can imagine, becoming the leader in the closed-cell, cross-linked polyolefin foam market did not happen overnight. This blog covers the history of SEKISUI Voltek and the start of making our Volara foam.
In 1969, SEKISUI Chemical in Japan, and High Voltage Engineering Corporation (HVEC) of Burlington, Massachusetts began a joint venture and founded the “Foam Corporation of America”. SEKISUI Chemical, brought the foam making technology to the partnership, while HVEC brought the critical technology of high-voltage radiation equipment to the process. A short time later, the name changed to SEKISUI Voltek to attract attention in the marketplace. “Volt” came from High VOLTage Engineering and “ek” from SEKisui. The “tek” ending was to convey a “high-technology” product.
The Beginning of Volara® Foam
In January 1970, Voltek moved to a new location in Lawrence, MA. The first sales of “Volara®” began by importing Softlon from Japan, which is the Japanese equivalent of Volara foam. In June 1970, shortly after installing the first foaming oven, production of Volara foam began using an extruded sheet from the sister plant in Japan. Later that year, a complete line of equipment, which consisted of an extruder, vault and oven began running the first production of Volara® foam in the US.
Eventually, increasing demand for Volara led to the decision to build another plant in Coldwater, Michigan. The City of Coldwater was ideal because of its centralized location and close proximity to the Big Three in Detroit. This allowed the company to focus on the development and expansion of Volara used for automotive interior trim and components. In 1975, HVEC sold its equity interest and SEKISUI Voltek became a wholly-owned subsidiary of SEKISUI Chemical.
A Variety of Foam Solutions
SEKISUI Voltek did not stop with just Volara. Eventually Volextra®, an extruded coating melt-bonded to Volara foam to give an extra design element, and VolaraBLOCK®, block foam for use in high-end packaging, dunnage, construction and transportation, were introduced to the market. Voltek also offers a variety of import products to round out the diverse mix of solutions we provide.
In 2020, the decision was made to close the Lawrence, MA facility and consolidate all operations to the Coldwater, MI location.
Continued Focus on Innovation
Our dedicated R&D Department continues to develop new solutions for the most demanding applications. Additionally, we can customize solutions such as non-halogenated FR, sustainable alternatives using calcium-carbonate filled foam, stearate-free options, and translucent foam to name a few. The possibilities are endless.
SEKISUI Voltek recently received Board approval for a $39M expansion to build a new plant. The new plant subsequently will increase production capabilities, allow for additional automation and ultimately reduce lead times. With over 50 years of innovation, the history of our Volara foam is rich, and we look forward to the next 50 years of innovation.
