Extrusion Materials
 Extrusion is the most important process where a billet is pushed and / or drawn by way of die for creating rod, or pipe in a specific shape. This process is also used to develop vinyl (PVC), aluminum & other profiles / components that are used to produce windows and doors. The extrusion process is carried out with the assistance of various Extrusions Machinery such as Extruder, PP / TQ Film Plant, Extrusion Lamination Plant, Synthetic String Plant, and others. There are mainly two types of extrusions processes, hot extrusion and cold extrusion.
In the Hot Extrusion Process, different products are manufactured using various materials that are also called Extrusion Materials. Mainly, the extrusion materials that are used include Aluminium, and Copper along with their alloys. Some of the other quality extrusion materials that are extruded using hot extrusion process are as follows:
- Magnesium
- Steel
- Titanium
- Nickel
- Refractory Alloys
Similarly, in the Cold Extrusion Process various products are developed from a range of materials. Some of the major Extrusion Materials include:
- Copper
- Lead
- Tin
- Aluminum Alloys
- Titanium
- Molybdenum
- Vanadium
- Steel
- Zirconium
- Niobium.
Depending on your requirements, you can choose different extrusion materials for developing an array of products. The selected material must have the capability of being extruded into the designed profile. The extrusion material specifications may or may not match the design requirements as desired by you, but if the material has low melt strength and low melt stiffness, then it may be possible to extrude it in the design geometry. Hence, it is very important to select the proper extrusion materials. Some of the good extrusion materials are as follows:
- Acrylic
- Acrylonitrile Butadiene Styrene (ABS)
- Polycarbonate (PC)
- Polyester (PETG)
- Polyethylene (High Density-HDPE, Low Density-LDPE)
- Polypropylene (PP)
- Polystyrene (General Purpose-GPPS, High Impact-HIPS)
- Polyvinyl Chloride (Rigid-RPVC, Flexible-FPVC)
During the selection of the extrusion materials, you must consider some of the important attributes related to them such as:
| Additives and Co-polymer |
Flexibility |
| Aesthetics |
Heat Stability |
| Chemical Resistance |
Impact Strength |
| Comparative Material Chart |
Rigidity |
| Flame Retardancy |
Smell |
| UV Stability |
