Hot-wire cut EPS sheets and 2D profiles to any drawing.
Kit queued
2D Shapes & Sheets is Technopol's custom CNC hotwire-cut expanded polystyrene (EPS) service — flame-retardant EPS cut to any 2D profile or cut-to-size sheet from a supplied drawing, in standard EPS grades from 12 to 30 kg/m³.

Grade-dependent: thermal conductivity, density and compressive strength vary by EPS grade (12 / 15 / 16 / 20 / 24 / 30 kg/m³). Best λ (0.033 W/m·K) and highest strength (200 kPa) are the EPS30 grade; the weakest end (0.045 W/m·K, 60 kPa) is EPS12. Confirm the specified grade. Fire scope: B-s1,d0 was determined on plain expanded polystyrene per SANS 53501-1, using the SBI test (SANS 53823) and ignitability (SANS 11925-2), at Ignis Testing Laboratory, Cape Town (tested Aug 2023, DJ Streicher Pr Eng 880107). The same FR-EPS is also rated B1 to SANS 10177-11 for thickness <120 mm. This is a reaction-to-fire classification of the material only — it is NOT a fire-resistance (REI) rating and not an assembly rating. Agrément SA 2020/609 is a company/product-range certification; no document in the corpus confirms its scope specifically covers plain cut EPS shapes/sheets (it is associated with Technopol's certified systems such as LiteCore/EIFS).
