64 DESIGN007 MAGAZINE I SEPTEMBER 2022 In this month's column, two of Electrolube's leading resin specialists have collaborated to give you the clearest focus of how introduc- ing bio-based resin systems will impact your production process and the benefits they bring in terms of performance. Beth Turner is Electrolube's senior technical specialist and Beth Massey is Electrolube's global product manager for resins. Having two Beths work- ing on resins may be a little confusing, but this column should help demonstrate the unique input each has and alleviate any confusion. Here we dive into how bio-based resins differ from their traditional counterparts, examin- ing what they can bring to the table, aside from their obvious sustainable and environmentally- friendly benefits. What percentage of the overall content can reasonably be bio-based without causing a detrimental effect to the performance of the product, and is the bio content added to part A or B? e honest answer to this question is quite simple: It depends. Realistically, up to 70% of content can be bio-based, and both A and B can contain bio-based materials. e 70% limit has more to do with availability of bio- based alternatives than high levels having a detrimental effect. It's likely that some com- ponents of the formulation will never have a bio-based alternative, but the benefits we are seeing from changing to bio-based raw mate- rials, where possible, does suggest we should Comparing Traditional and Bio-based Resins Sensible Design by Beth Massey and Beth Turner, ELECTROLUBE
