The fast-curing elastomer casting resin: FastElast from Synthene
FastElast, Synthene’s new range of fast setting vacuum casting resins.
In order to meet the ever-increasing requirements and constraints of the prototyping market and industry in general, Synthene is now able to offer you, as a complement to its HPE range, the FastElast range.
The FastElast range is available as follows:
- Two Polyols: FastElast 35P and FastElast 93P
- 1 Isocianate: FastElast Iso
What is the FastElast system used for?
The FastElast system is a polyurethane elastomer system for the production of flexible parts for prototyping and other technical needs.
Two polyols are combined with an isocyanate to obtain several types of elastomer parts:
- very flexible 35 ShA
- to the semi-rigid 93 ShA (=50-55ShD),
- while offering excellent mechanical performance.
Processing properties depending on the desired hardness
| Hardness | 35A | 45A | 50A | 60A | 65A | 75A | 80A | 86A | 93A |
|---|---|---|---|---|---|---|---|---|---|
| FastElast 35 A Polyol (g) | 100 | 90 | 85 | 75 | 60 | 45 | 30 | 10 | – |
| FastElast 93 A Polyol (g) | – | 10 | 15 | 25 | 40 | 55 | 70 | 90 | 100 |
| FastElast 35-93 A Isocyanate (g) | 30 | 37 | 41 | 48 | 58 | 69 | 79 | 93 | 100 |
| Viscosity BROOKFIELD LVT at 25°C (mPa.s) According to MO-051 | 350 | 310 | 310 | 300 | 300 | 300 | 300 | 300 | 300 |
| Reactivity on 200 g at 25°C (min.) According to MO-062 | 12 | 10 | 8’30 | 12’30 | 10’30 | 6 | 7 | 5 | 6 |
| Demoulding time at 70°C (h) in-mould proofing at 70°C | 2 | 1 | 1 | 1 | 1 | 1 | 1 | 1 | 1 |
The benefits of Synthene’s FastElast system:
- Very low viscosity (between 300 and 350mPa.s) which allows a fast filling of the moulds. This viscosity is particularly adapted to the vacuum casting process.
- Demoulding time at 70°C one of the fastest on the market!
Demoulding after 1 hour for hardnesses from 45 Shore A to 93 Shore A (2 hours for 35 Shore A)
- Very good Elongation at break (up to 1110% for 45 Shore A ) and very good tear resistance.
- Very easily colorable in any light or dark color.
| Hardness Shore A ISO 868 | 35* | 45 | 50 | 60 | 65 | 75 | 80 | 86 | 93 |
|---|---|---|---|---|---|---|---|---|---|
| Elongation at break at 23°C (%) ISO 37 | 385 | 1110 | 732 | 765 | 770 | 830 | 630 | 680 | 616 |
| Tensile stress at break at 23 °C (MPa) ISO 37 | 1,4 | 2,7 | 4,7 | 5,8 | 8,3 | 12,5 | 13 | 26 | 22 |
| Tear strength at 23°C (kN.m-1) ISO 34 | 7,8 | 7 | 15,1 | 25 | 29,4 | 41,2 | 45 | 74 | 60 |
*Results obtained after 2 hours at 70°C + 7 days at RT
