In the printing industry, the choice of ink is crucial, as it not only determines the quality of the printed product but also involves safety issues during production. Plastisol Ink, also known as heat-set ink, is a non-solvent-based ink widely used in textile printing, handicrafts, and other fields. This article will delve into the flammability of plastisol ink and its suitability for printing on newborn products, while introducing the knowledge of the International Coatings Plastisol Ink Chart and the International Coatings Plastisol Ink Color Chart to comprehensively analyze the characteristics and applications of plastisol ink.
I. Composition and Characteristics of Plastisol Ink
Plastisol ink is mainly composed of resin (without solvent or water), pigments, and other additives. Its appearance is paste-like, with thixotropy, meaning it is thicker when left stationary and becomes thinner when stirred. This characteristic makes plastisol ink easy to handle during the printing process and adapts to various manual and mechanical printing needs. Plastisol ink does not dry at room temperature and must be heated to 150°C to 180°C and baked for 1 to 3 minutes to fully cure. The cured ink is elastic, with a surface that cannot be scratched or powdered, showing high adhesion strength.
II. Flammability Analysis of Plastisol Ink
2.1 Chemical Composition and Combustion Characteristics of Plastisol Ink
Is Plastisol Ink Flammable During the Printing Process? Are There Fire Risks?As a non-solvent-based ink, plastisol ink does not contain flammable solvents, thus reducing the fire risk to a certain extent. However, any material can burn under specific conditions, and plastisol ink is no exception. Although its ignition point is high, it can ignite under high temperatures or direct contact with a fire source. Therefore, strict safety regulations must be followed during storage and use to avoid fire sources and high-temperature environments.
2.2 Fire Risk Assessment
The fire risk of plastisol ink mainly depends on its storage and use conditions. During the normal printing process, since the ink needs to be heated for curing, the safety and stability of the heating equipment must be ensured. Additionally, the printing workshop should maintain good ventilation to reduce the concentration of ink vapors in the air, thereby further lowering the fire risk.
III. Difference Between Plastisol Ink and Solvent-Based Ink
3.1 Characteristics of Solvent-Based Ink
Solvent-based ink uses organic solvents as carriers, which are usually flammable and explosive. Therefore, solvent-based ink poses a higher fire risk during storage and use. Additionally, solvent-based ink causes environmental pollution and poses health hazards to humans.
3.2 Advantages of Plastisol Ink
In contrast, as a non-solvent-based ink, plastisol ink has significant advantages. It not only reduces the fire risk but also lowers environmental pollution. Meanwhile, plastisol ink’s adhesion and abrasion resistance are superior to many solvent-based inks, making it widely used in textile printing and other fields.

This chart allows users to quickly understand the key indicators of different inks, such as curing temperature, adhesion, and abrasion resistance, thereby selecting the most suitable ink for their needs.
4.2 International Coatings Plastisol Ink Color Chart
The International Coatings Plastisol Ink Color Chart provides a rich selection of colors. This chart covers various common and special colors, enabling users to easily choose the right color combination based on design requirements. Additionally, the color chart provides color matching suggestions and printing effect previews, helping users better realize their design creativity.
V. Application of Plastisol Ink in Newborn Product Printing
5.1 Safety Considerations
The printing requirements for newborn products are extremely high, and the safety of the ink must be ensured. As an environmentally friendly ink, plastisol ink does not contain heavy metals or harmful chemicals, thus complying with the safety standards for newborn products to a certain extent. However, in practical applications, the amount of ink used and curing conditions must be strictly controlled to ensure the safety and harmlessness of the printed products.
5.2 Printing Effect and Durability
Plastisol ink performs excellently in newborn product printing. Its high adhesion and abrasion resistance make the printed products less likely to fall off and fade during long-term use. Additionally, the vibrant and full colors of plastisol ink can well display the design effects.
VI. Fire Prevention Measures for Plastisol Ink
6.1 Storage Safety
Plastisol ink should be stored in a cool, well-ventilated warehouse away from fire sources and high-temperature environments. Additionally, the packaging and containers of the ink should be regularly inspected to ensure they are intact and prevent leakage and evaporation.
6.2 Use Safety
When using plastisol ink, strict operating procedures and safety regulations must be followed. Heating equipment should have good temperature control and overheat protection devices to prevent excessively high temperatures from causing fires. Furthermore, the printing workshop should be equipped with corresponding fire-fighting facilities and emergency rescue equipment to respond to unexpected situations.
6.3 Employee Training
Employees should receive regular fire safety training to improve their safety awareness and emergency handling capabilities. The training content should include fire prevention knowledge, the use of fire-fighting equipment, and emergency evacuation procedures.
Következtetés
In summary, as a non-solvent-based ink, plastisol ink performs excellently during the printing process and has broad application prospects. Although it poses a certain fire risk, this risk can be effectively reduced through strict storage, use, and management measures. Meanwhile, the environmental friendliness and safety of plastisol ink also make it an ideal choice for newborn product printing. Therefore, in the printing industry, plastisol ink will continue to play an important role in ensuring the quality and safety of printed products.
