Synfill-G from Synthene, the new glass fibre filler for reinforcement
Why use SynFill-G fiberglass filler?
It is advantageous to use Synthene’s Synfill-G filler when we need to increase the tensile and flexural strength of the vacuum casting resin. The Synfill-G filler therefore allows the production of parts with higher flexural and tensile moduli of elasticity.
Synthene’s SYNFILL G filler is added between 15 and 25% to the resin at the time of mixing (such as PR700, PR777, PR500 …). It allows to almost double the flexural modulus of a resin, while remaining easily pourable in a silicone mould. It is compatible with all Synthene vacuum casting resins.
Benefits of SynFill-G glass fiber filler for vacuum casting resins
- Increased tensile and flexural strength
- Increased material rigidity
- Improvement of temperature resistance
- Reduced coin removal
- Wide range of possibilities depending on the applied load rate
How to use SynFill-G fibreglass filler?
 |
 |
 |
| 1. Weigh parts A and B of the polyurethane, add SynFill G to the Isocyanate part. | 2. Place parts A (Polyol) and B (Iso + SynFill G) of the polyurethane in the vacuum casting machine. | 3. Vacuum casting with a mould preheated to 70°C. |
