| Résumé : |
Silicone rubber cannot yet be processed by extrusion blow molding. A new approach ensures a low level of pre-crosslinking of the material, providing it with sufficient elasticity for it to be inflated to form elastic hollow bodies. This development offers economic and technical alternatives to the hollow bodies that were previously manufactured by complex conventional processes. |
| Note de contenu : |
- Production of pre-crosslinked tubes
- Pre-crosslinking improves blow moldability
- Forming of hollow bodies with silicone rubber
- Fig. 1. Structure of the die head for the blow molding of silicone rubber
- Fig. 2. Parison swelling : wall thickness and diameter of the pre-crosslinked parison over the parison length as a function of pre-crosslinking degree
- Fig. 3. Free inflation at 25°C parison temperature : diameter when the 13 cm long parison bursts and maximum stretching ratio depending on pre-crosslinking degree
- Fig. 4. Free inflation at 25°C parison temperature : development of the outer contour of the parison : a) at 1 wt.% pre-crosslinking degree, b) at 4 wt.% pre-crosslinking degree
- Fig. 5. Free inflation of the parison at different temperatures : development of the diameter as a function of time during inflation
- Fig. 6. Development of the outer contour of the parison with e pre-crosslinking degree of 4 wt,% on Inflation directly after extrusion (110°C parison temperature)
- Fig. 7. General development of the outer contour of the parison at 110°C during inflation in a glass bottle |
