What Schill + Seilacher does

Schill + Seilacher "Struktol" GmbH is a privately held German specialty chemicals manufacturer founded in 1877 and headquartered in Hamburg, with a secondary production facility inaugurated in 2025 in Pasir Gudang, Malaysia. The company develops and produces chemical additives and processing aids across six core product lines: rubber additives (lubricants, peptisers, homogenizers, plasticisers, vulcanisation activators, metal oxide and sulphur preparations), antifoams (for biotechnology, food, and technical applications), reactive polymers and flame retardants (including biobased reactive resins for composites and prepregs), latex additives (stabilisers, antioxidants, antifoaming and dewebbing agents, thickeners, tackifiers), silicones (marketed under the STRUKSILON, Sil-O-San, and VP series brands across cosmetics, polyurethane, construction, leather, textile, and agrochemistry applications), and release agents (the Permalease semipermanent mould release system plus the MR mandrel release series).

The company's value proposition centers on deep domain specialization with quantified processing outcomes such as reduced compound viscosity, decreased silica re-agglomeration, improved extrusion rates, and reduced tan delta in silica-filled compounds. It serves eight primary vertical segments, with tire and rubber manufacturing and automotive suppliers as the lead markets, supported by direct B2B sales with strong technical service and a regional distribution partnership with Jebsen & Jessen for APAC. Revenue is generated through direct specialty chemical sales under quote-based pricing and multi-year contracts; pricing is not publicly disclosed. The firm holds EcoVadis, TÜV, and REACH certifications, operates a dedicated careers portal, and markets through its website (struktol.de), industry trade shows, downloadable technical documentation, and active social media channels.
