How Regradia compares
Coverage, neutrality, and cost —
vs the vendor-paper alternative.
Most of what an extrusion operator finds on the open web is written behind a form gate or behind an hourly invoice. Regradia is built the other way around — the playbook is the product, the comparison below is the reasoning behind it, and the CTA at the bottom lands you back in the playbook.
Block 1 · Coverage
Depth on the six flagships — and the gap vendor papers leave.
Regradia carries deep coverage on six recurring extrusion defects. Vendor white papers typically treat the same symptoms as additive-residue or screw-speed problems and stop there — the second- and third-generation failure modes are the part that drifts out of scope.
Vendor-paper gap
White papers treat surge rhythm as a feed-throat problem and stop at screw-speed trim. The 3rd-gen failure mode (mixed rheology pressing against a tighter melt-viscosity floor) is typically a footnote.
Vendor-paper gap
Most vendor content frames lip buildup as an additive-residue problem and prescribes a lube-package change. The oxidative-carryover case on 3rd-gen streams is out of scope in the published write-ups.
Vendor-paper gap
Single-mode loading (fibre fines) is well-covered; uneven polyolefin-oxidation loading on a 3rd-gen bale stream — the case where the pack pockets and breaks through in spikes — is the gap.
Vendor-paper gap
Recipes are calibrated against a single failure mode (PE/PP crosslink). Mixed-mode survivals on 3rd-gen (PVC/PET contamination plus oxidized-PP islands) are usually treated as out of scope.
Vendor-paper gap
Devolatilisation notes in vendor literature stop at vent sizing. The 2nd/3rd-gen carry-over budget — what the conversion window actually absorbs before condensate shows up — is the missing detail.
Vendor-paper gap
White papers cover MFI as a test method, not as a recipe variable. Lot-to-lot spread as the feedstock shifts from 2nd to 3rd gen is the silent contributor most recipes do not restate.
Block 2 · Neutrality
Independent on three axes where vendor content is not.
Regradia has no equipment-supplier tie-in, no resin SKU to sell, and no preference for 1st-gen over 2nd/3rd-gen feedstock. The neutrality is structural, not a marketing line — the platform has nothing to upsell.
Typical bias
Aligned to extruder / filter OEM — recipes assume their additive package and mesh schedule.
Regradia position
Independent of any equipment supplier. No OEM mix upgrade is recommended because a specific melt filter is on contract.
Typical bias
Aligned to resin supplier portfolio — articles steer toward a higher-grade resin or a stabiliser top-up.
Regradia position
Tracks off-spec material VALUE (downstream recovery, converter-window held) rather than resin resale. No resin SKU is preferred because the platform sells it.
Typical bias
Recipes tuned to 1st-gen / near-virgin feedstock; 3rd-gen is a footnote or an "edge case".
Regradia position
Equally covers 2nd and 3rd generation feedstock. The defect entries treat generation drift as a primary variable, not a closing paragraph.
Block 3 · Cost
Free playbook, instead of an hourly invoice — or a sales-led funnel.
Below is a side-by-side of how the three approaches differ in cost, time-to-answer, and ownership of the recipe. Numbers are illustrative European SME extrusion-line ballparks, not a price list — the structural difference is what matters.

Block 4 · Open the playbook
Ready when you are.
The playbook is open, ungated, and versioned.
Every defect entry has a symptoms-to-recipe lookup, a process variable table, and a verification step — written from the line back to the variable, not from a sales deck. No form, no intake, no hourly invoice.
