Scope 2: indirect emissions for polymer manufacturers – typically involving energy produced, such as steam or electricity during manufacturing.  Amongst all of these activities in the value chain, the EPA states that the highest account of emissions derives from the transportation of goods (28%), electricity (24%), and manufacturing (12%). There are a number of options available when using sustainable raw materials in your final formulations.

Continuous filament wound tubes also provide excellent electrical insulation for construction applications. Resin matrix and fiber loading formulated to meet your property requirements Infographic: Advanced Composites for Demanding Applications
