EPS & HIPS Resin Supplier
Self-extinguishing EPS resin for building insulation, fire-rated packaging and applications where flame retardancy is required. Grade C specifications (C-102 to C-108) offer a full range of bead sizes for block and high-density applications.
Product Overview
Grade C self-extinguishing EPS meets B1-class fire resistance requirements and is widely used in building insulation boards, construction block moulding and fire-rated packaging. The inherent flame retardancy is achieved through additive incorporation during polymerisation.
Available in 7 bead size specifications (C-102 to C-108). Compared to standard grade, C-series shows a lower foam multiple at the same bead size, providing higher base density for insulation and structural applications.
