Manufacturer Datasheet Sources

Manufacturer datasheets are often the best engineering reference for an exact grade, product form, fibre/resin system, seal compound, glass product, cure, or test condition. PropLib keeps official source links, but it does not assume that a free PDF grants permission to republish the values in a public database.

Current public-data rule

A datasheet value can enter the public JSON only when the copyright holder provides an open-data/content license or explicit permission covering redistribution of the extracted values. license_status: unknown remains blocked.

Publicly linked but uncleared sources stay reference-only. Their values may be used in the private edition if the applicable terms permit internal use.

Official source families

Toray carbon fibre and prepreg, Gurit, and Owens Corning composites.

• Elastomers: Parker O-Ring Handbook,

DuPont Kalrez, Wacker ELASTOSIL, and Trelleborg O-rings.

• Adhesives and insulation: 3M Scotch-Weld

and Owens Corning Fiberglas board.

The detailed review status is maintained in the source workspace at data/private/source_candidates/manufacturer_datasheets.json. That file has links and rights notes only, not copied property values, and is omitted from the public build.

Before a source is promoted

Record the exact document revision, stable official URL, license or written permission, attribution, grade and condition, test method, typical/minimum/ maximum semantics, source hash, and design-release boundary. Then implement a small deterministic importer instead of manually editing the generated catalog.
