About this file

This document is a federal contract attachment specifying technical requirements for a Delrin plastic sheet manufactured by DuPont (AF DE 588). The contract (SPMYM325Q9023) requires a specific plastic sheet with precise material properties, including 1-1/4" thick x 12" wide x 48" long dimensions. The technical specifications detail exact mechanical and physical characteristics to be tested using ASTM methods, such as specific gravity (1.50 - 1.57), tensile strength (6100 PSI minimum), melting point (172 - 184 deg C), and Teflon fiber content (18 - 23%). Additional requirements include dimensional stability testing in a mineral oil bath and submission of mechanical property test reports and compliance certification through Exhibit A, Sequences A001 and A002.

3. The test method to determine dimensional stability shall be performed as follows: The test specimens (finished pieces) tested shall be measured at 23 +/- 3 deg C (73 +/- 5F) and placed in a mineral oil* bath maintained at 160 +/- 3 deg C (320 +/- 5F) the specimens shall remain in the bath for six (6) hours at temperature and allowed to slow cool in the bath at a rate not to exceed 23 +/- 3 deg C (73 +/- 5F) per hour. When the bath reaches 23 +/- 3 deg C (73 +/- 5F), the test specimens shall be removed and measured. The percent change in each dimension, outside diameter, inside diameter and thickness shall not be greater than the value specified.

*Mineral oil meets the specification as listed below:
