How the library is prepared.
The standard is usefulness: a reader should understand more after the page than before it.
Originality
Content is intended to be written for this site and structured around practical plastic-industry questions. We do not intentionally republish another publisher's article or build pages by lightly rewording copied material. Articles are organized around a real decision, problem or comparison rather than a generic definition.
Accuracy
Technical values are presented as typical ranges or explanations when a grade-specific value would be inappropriate. For production, safety, food contact, medical or regulatory decisions, readers should verify the exact requirement against current supplier data and applicable official requirements. We also clearly separate educational guidance from product certification or compliance advice.
Corrections
When a factual error is identified, the page should be corrected rather than silently repeated. Readers can report an issue through the contact page. Corrections are part of the quality process and are treated seriously.
AI-assisted drafting
Digital tools may assist with research organization, formatting or drafting. They are not treated as a substitute for editorial judgment. The goal is useful content with context, limitations and application-specific thinking—not mass-produced pages created only to capture search traffic. AI output is reviewed and adapted to our editorial standards before publishing.
Commercial neutrality
PlasticInfoHub is not a manufacturer's sales catalogue. Where a named product or trade name is mentioned, the purpose is to explain the material or technology, not to imply endorsement. We also avoid giving the impression that a page is a substitute for a supplier specification sheet.
Editorial workflow
- Identify the real reader question and the decision the content is meant to support.
- Explain the concept in clear language with practical context.
- Include examples, limitations and trade-offs instead of shallow summaries.
- Review factual claims before publication.
- Update or correct the page when better information becomes available.
