What Sunpor Kunststoff does

SUNPOR Kunststoff GmbH is an Austrian manufacturer of expanded polystyrene (EPS) granules, headquartered in St. Pölten with two ISO-certified production facilities (Stattersdorf and Radlberg) and total annual capacity of 260,000 tonnes. The company is a subsidiary of Norwegian industrial group O.N. Sunde AS and operates as a B2B supplier to EPS processors across Europe and select international markets including Japan and China. Its product portfolio spans standard grades (sunpor STD/SE), the proprietary Lambdapor line of graphite-infused grey EPS delivering up to 25% better insulation performance than white EPS (including generation2, R10, and R15 variants with recycled content), colored EPS (suncolor), high-density specialty products (Lambdalit), the more circularity line of recycled-content products (repor, Lambdapor R10/R15), and segment-specific grades (powerpor, roofpor, terrapor, sunpor bio Infill).

The company serves four primary verticals: construction and building insulation (the largest segment, with applications in WDVS, roof, floor, and perimeter insulation), protective packaging, sports safety equipment (notably helmets via suncolor circolor 100), and cold chain/specialty applications including vaccine transport. Sunpor generates revenue through direct sales to industrial customers via a regional account management team, with quote-based B2B pricing on multi-year contracts. The company holds ISO 9001 and 14001 certifications at both plants, Responsible Care certification, Operation Clean Sweep/Zero Pellets Loss commitments, flustix RECYCLED certification for circular products, and renewable energy certification supported by a 500 kWp photovoltaic installation at the Radlberg site. It is a founding member of the PolyStyreneLoop initiative (68+ companies) and co-developer of the CreaSolv solvent-based recycling process with Fraunhofer IVV, positioning it at the center of European EPS circular economy infrastructure.

Core offering

SUNPOR Kunststoff GmbH manufactures and sells Expanded Polystyrene (EPS) granules for industrial processors across Europe. Its portfolio includes standard EPS grades (sunpor STD and SE), grey graphite-based insulation EPS (Lambdapor and Lambdapor generation2), colored EPS (suncolor) for helmets and packaging, high-density specialty foam (Lambdalit), and a "more circularity" line of recycled-content products. Output is sold B2B to insulation board manufacturers, packaging producers, helmet makers, and cold-chain industrial customers, with 260,000 tonnes annual production capacity across two plants in St. Pölten, Austria.

Product overview

Sunpor Kunststoff is a leading global manufacturer of EPS (Expanded Polystyrene) granules, producing a comprehensive product portfolio for insulation, packaging, and specialty applications. The core product lines include: sunpor® STD and SE (standard EPS granules in various grades for general applications), Lambdapor® family (grey EPS with graphite particles for superior insulation - available in generation2, R10 with 10% recycled content, and R15 with 15% recycled content), suncolor® and suncolor circolor® 100 (colored EPS including 100% recycled option for helmets and packaging), Lambdalit® (high-density EPS for specialty applications like pool systems), and repor® 33 (recycled packaging material). The 'more circularity' product line represents the company's focus on sustainable circular economy, offering recycled-content variants across key product categories. The company operates primarily in building insulation (where EPS saves many times the energy used in production) and protective packaging sectors, with total production capacity of 260,000 tons per year across two facilities in St. Pölten, Austria.
