Engineered Plastic Composites
The Engineered Plastic Composites (EPC) market is significant, with a global value of $4.05 billion in 2015. The largest EPC market segments are building and construction (65%), automotive (18%), and electrical (8%), with the remainder being miscellaneous applications. Tremendous global EPC production growth is expected – marketing studies predict a 12.3% compound annual growth rate (CAGR), reaching $8.76 billion in 2023 (6 million tons/year of new EPC manufacturing demand).
Because EPC-based construction materials are typically made using wood as filler material, they present challenges of pressure-treated lumber, including water absorption, recyclability – and especially cost. ISEE is developing engineered composite materials utilizing natural carbon filler sources, such as coal, resulting in lower cost products with equal or superior performance properties. Performance data to date shows OHIO natural carbon plastic composites (CPCs) possess greater flexure strength and slower burn rates compared to commercial composite decking products, while recent cradle-to-gate life cycle analyses indicate CPCs – in comparison to commercial composites – emit 30% less GHG emissions and require 60% less energy to manufacture. ISEE is currently working with industry to scale these materials using commercial manufacturing equipment and assess additional applications.
Advantages
- Lower cost owing to a combination of cheaper filler and reduced polymer consumption per composite unit
- Increase in composite durability due to resistance to water absorption and biological attack.
- Safer material due to improved fire rating for the composite
- Better composite mechanical properties including flexural and tensile strength.
