Polly Plastics

Aerospace plastics, cut to your size. Priced in seconds, certified the same day.

PEEK, natural (unfilled) carries residual stress. A cut blank can bow 0.010-0.025 in within 48 hours as that stress releases.

The three costs of a full sheet

The minimum order

A 48 x 24 in PEEK sheet at 0.5 in runs 27.2 lb of raw material - about $2,997 before any cutting. A single 12 x 12 in blank needs $375 of it. The other $2,622 sits on a shelf.

Squaring hours

A sheet arrives with four rough edges. Every one needs to be squared on your own saw before a part comes off it - setup, blade wear and floor time you pay for on every job, not just this one.

The paperwork delay

A commodity blank usually means a quote request, a wait for a person to price it, then freight arranged - days before a saw ever touches the sheet.

Every Tier-2 and Tier-3 shop running a defense or aerospace contract has waited on a distributor to answer a $400 quote request. We built this for them: a firm price in seconds, a blank that's actually square, and certification paperwork the same day we cut - not the same week.

Your distributor takes three days. We take five seconds.
