Plastisol is defined as the mixture of the polymer Polyvinyl Chloride (PVC) with plasticizers and other materials (additives) to achieve a variety of products.
Plastisol is used in a wide range of metallic coatings, moldings, and technical parts, offering unique physical properties and customized colors.
Main Properties of Plastisol
- Can be produced with adjusted viscosity and colors for different application processes
- Can be produced with adjusted elongation and elastic modulus for various specifications
- Can be expandable or non-expandable
- UV resistant
- Plastisol cures between 160 – 210 degrees Celsius
Types of Applications
1. Dip Coating:
The metal to be coated must be heated to a temperature between 180º and 210º C, while the Plastisol remains at room temperature.
Once the metal reaches the appropriate temperature, it is immersed in the Plastisol for 10 to 20 seconds, depending on the desired thickness. The metal is then removed and placed in an oven for full curing.
It is important to maintain the same temperature in the oven as the metal was initially heated to. After 10 to 15 minutes, the metallic piece can be removed.
2. Molding:
This process involves obtaining parts by placing Plastisol into a mold. The final piece can then be cured in an oven at 180º C.
3. Rotomolding:
This process produces hollow parts, such as balls. It involves dosing Plastisol into a mold either manually or with dosing machines. The mold is placed in a large oven where it undergoes continuous 360-degree rotations, ensuring the Plastisol is evenly distributed to cover the entire surface of the mold.
Advantages of Rotomolding include:
- Cost-effectiveness
- Dosage control
- Low volume of product loss
- Uniformity of the final product
- Weight standardization
- Reduced raw material waste
