Applications
Elastomers for parts that work under load
Reactan prepolymers are cured at your plant with MOCA or TIPA/TMP to make parts with high abrasion, tear and load resistance.
-
Rollers
Covers for industrial rollers that need abrasion resistance and dimensional stability.
-
Wheels
Treads for wheels that carry heavy loads.
-
Seals and bushings
Seals, gaskets and bushings that must resist wear.
-
Mats
Mats and technical sheets for impact and wear zones.
Selection guide
Choose by hardness and curative
Final hardness depends on the prepolymer and the curative. MOCA gives the grade’s nominal hardness; TIPA/TMP gives a softer elastomer.
| Product | Chemistry | MOCA Shore A | TIPA/TMP Shore A | Gel time at 80 °C min |
|---|---|---|---|---|
| PES-80 | Polyester / TDI | 80 | < 50 | 14 |
| PES-90 | Polyester / TDI | 90 | < 60 | 8–10 |
| PTMEG-80 | Polyether / TDI | 80 | 50 | 18 |
| PTMEG-83A GR | Polyether / TDI | 83 | 53 | 5 |
| PTMEG-90 | Polyether / TDI | 90 | 60 | 11 |
Note: “<” means “below”. Gel time measured at 80 °C with MOCA.
Casting process
Parameters shared by all five products
- 01Prepolymer at 85 °CHeat the prepolymer to mixing temperature.
- 02MOCA at 110 °CMelt the curative and dose per the data sheet (10.5–13.6 g per 100 g).
- 03Mold at 100 °CMix and pour within the grade’s gel time (5–18 min at 80 °C).
- 04Post-cure 16 h at 110 °CDemold and post-cure to reach data-sheet properties.
