What are the benefits of Casting and Injection Molding Urethanes?
Castable Polyurethane Systems:
- Have superior mechanical properties over Injection Moldable polyurethane systems in abrasion and compression set
Injection Moldable Polyurethane Systems:
- Have superior manufacturability over Castable polyurethane systems (about half the manufacturing cost)
PriPro’s X-Link Injection Moldable / Extrudable Polyurethane System:
- X-Link gives you the best of both—superior mechanical properties AND manufacturability!
Which Properties are improved by Cross-Linking?
PriPro’s Patent Pending X-Link TPUs offer benefits in the key areas of:
- Tensile Strength
- Abrasion Resistance
- Compression Tolerance
- Tear Strength
- Chemical Resistance
- Manufacturability
Why Cross-Link Polyurethanes?
- Form Hydrogen Bonds easily
- Make Block copolymers with other types of soft rubbery polymers
- Make Block copolymers by cross-linking effectively with the linkages of Urethanes and Ureas
- Meet most of the requirements of “Engineered” polymers when combined with the right choice of Ester or Ether link
Where can I use X-Link Technology?
- Pripro’s proprietary additives and processing techniques can be applied to all parts currently Injection Molded using “off-the-shelf” injection moldable grade thermoplastic urethanes, resulting in parts having properties like Castable Urethanes.
- Pripro’s proprietary materials and processing techniques can also be applied to Extruded Sheets and Profiles
What are the requirements for Post Curing?
- X-Link Polymer TPUs must be post cured and aged for two weeks to achieve full mechanical properties.
Typical Post Curing Range Requirements
8 - 12 hours at 180 - 240°F
(Based on part size and thickness)
What does the word “PriPro” mean?
- “PriPro” means Innovative or Novel. Thus the meaning of PriPro X-Link Polymers ® is “Innovative Cross-Linked Polymers”.
