Hannah L. Prescott

Biography

Hannah L. Prescott is a chemical and materials reference writer with 14 years of hands-on experience around industrial and laboratory materials — polymer selection, chemical resistance screening, and safety-data interpretation. The compatibility guidance on this site reflects that practical bench and field work rather than any formal title.

After repeatedly watching technicians and buyers lean on outdated or anecdotal compatibility charts — sometimes at real cost — she started ChemRefHub to compile a single, practical reference that cross-references manufacturer technical datasheets with everyday test observations. Every compatibility rating on this site is grounded in manufacturer documentation and hands-on handling experience.

Experience

• 14 years of hands-on work with industrial plastics, rubbers, and metals
• Practical experience in chemical resistance screening and safety-data review
• Longtime lab and workshop handling of solvents, sealants, and specialty materials
• Working familiarity with GHS labels and safe-storage routines
• Reference compiling grounded in ASTM D638, D2240, D543, and D471-style test practice

Role at ChemRefHub

As founder and lead editor of ChemRefHub, Hannah oversees all chemical data sourcing and compatibility rating work. Each entry is cross-referenced against independent public sources — PubChem for physical properties, manufacturer SDS and data sheets for compatibility, and official hazard-classification publications. She reviews user-reported corrections within 5 business days and updates the database quarterly.
