Sika · SikaBiresin TP103
SikaBiresin TP103 is a reinforced polyolefin on a polypropylene base with increased thermal conductivity – a property few 3D printing materials offer. Sika designed the range explicitly for pellet extruders and complex mould-tooling applications.
Rated 1 to 5 relative to the other materials in our range. This is an experience-based orientation aid, not a measured value – the hard numbers are in the table below.
| Property | Value | Source |
|---|---|---|
| Base | FPO based on polypropylene, black | Sika TDS 04/2025 |
| Supply form | Pellets, designed for 3D printing extruders | Sika TDS 04/2025 |
| Density (ISO 1183-1) | 1.14 ± 0.03 g/cm³ | Sika TDS 04/2025 |
| Shore D hardness (ISO 868) | 74 ± 3 | Sika TDS 04/2025 |
| Tensile modulus (ISO 527-2) | ≥ 3,200 N/mm² | Sika TDS 04/2025 |
| Tensile stress at yield (ISO 527-2) | 31 N/mm² | Sika TDS 04/2025 |
| Tensile strain at yield (ISO 527-2) | 2.5 % | Sika TDS 04/2025 |
| Heat deflection temperature HDT B (ISO 75) | 149 – 155 °C | Sika TDS 04/2025 |
| Melting temperature (ISO 11357-3) | 170 ± 10 °C | Sika TDS 04/2025 |
These values are taken from the manufacturer datasheet and apply to the material, not to the printed part. In 3D printing the achievable properties depend on part orientation, layer height and process parameters – in the Z direction in particular they are lower. Please talk to us before relying on them for design.
“Qualified for functional parts” is a general classification. A functional part can be a simple clip or a main load-bearing member – the forces and load cases differ fundamentally. We therefore always assess in each individual case whether a material is suitable for your part.
