Irradiation and post-cure processing of elastomers

摘要

Processing methods are described for improving the physical properties of elastomeric materials including elastomeric tubing. The methods include heating tubing in a post-cured step for a specified time and at a specified temperature. The methods also include irradiating the tubing with a desired dose of radiation. Embodiments can include treatment of silicon-based elastomers and/or non-silicon-based elastomers. The improved elastomers can be utilized in pumps.

主权项

1. A method of processing elastomeric material, the method comprising:
providing a segment of elastomeric tubing already having had a first exposure to heat, and having a first radial strength; heating the segment with a second exposure to heat for an exposure time at a specified temperature; irradiating the segment with a specified dose of radiation; and providing the segment as a strengthened segment of elastomeric tubing having a second radial strength greater than the first radial strength.
