SILON s.r.o.

What SILON s.r.o. does

SILON s.r.o. is a Czech manufacturer of polyolefin-based polymer compounds serving industrial B2B customers across more than 40 countries. Founded in 1950 by Otto Wichterle initially as a polyamide filament yarn producer, the company pivoted to plastic compounding in 1983 and since 2022 — following a fibre-division spin-off — has specialized in compounds based on polyethylene (PE) and polypropylene (PP). Its product portfolio consists of four registered brand families: TABOREX® (PE-Xb silane cross-linkable compounds for pipes, fittings, and underfloor heating), TABOCAB® (HFFR and XLPE compounds for cable insulation and sheathing), TABOREN® (mineral- and glass-filled PP/PE compounds for industrial use), and TABOREC® (recycled plastics sold as regranulate and regrind). Beyond branded products, SILON provides tailor-made and toll compounding services, plastic recycling services, and dedicated R&D support through an in-house laboratory.

The company's technology stack centers on reactive extrusion, silane cross-linking (Sioplas/Monosil methods), and filled-compounding production using twin-screw extruders (75–135mm), Buss-Kneaders, and Erema recycling equipment. It operates an 85,000-tonne compounding facility at Planá nad Lužnicí (Czech Republic), an 8,000-tonne recycling plant at Libuň (Czech Republic), a US production plant in Peachtree City, Georgia (established 2017, with a new production hall under construction in 2024), Group headquarters in Prague, and a sales office in Düsseldorf. The company holds ISO 9001, IATF 16949 (automotive), ISO 14001, ISO 45001, Responsible Care, PRS Green Label, and a 2026 regional waste-operations authorization, and employs approximately 258 colleagues across the SILON Group.

SILON monetizes through direct B2B enterprise sales of branded compound products and toll compounding contract-manufacturing services, supplemented by plastic recycling processing fees. Distribution is via regional sales teams organized by product line (TABOREX, TABOCAB, TABOREN, TABOREC), supported by technical customer support specialists and trade-fair-driven demand generation at events such as PLASTINDIA, PLASTEX, K-FAIR, and AMI Fair. End-use segments span pipes and fittings, tubes and cables, building and construction, automotive, consumer products, food contact materials, healthcare, renewables, and broader industrial applications.
