PVC heat transfer trademarks and silicone heat transfer trademarks each have their own characteristics, and which one is better depends on the specific application requirements and scenarios. The following is a detailed comparison of the two:
1. Material characteristics
PVC heat transfer trademark
Ingredients: PVC rubber seals are mainly made of DNP oil, PVC powder, stabilizer, soybean oil and other materials.
Environmental protection: PVC has a relatively low environmental protection coefficient and a strong odor, which is more common in the mid- and low-end markets. In addition, harmful gas emissions and waste may be generated during the production process of PVC trademarks, which will have a certain impact on the environment.
Heat resistance: PVC has poor temperature resistance and is easy to decompose and produce hydrogen chloride at high temperatures, which further catalyzes decomposition and causes discoloration and degradation of physical and mechanical properties.
Silicone heat transfer trademark
Ingredients: Silicone rubber seals are made by heating liquid silicone oil and solid silicone in a mold with a vulcanizer.
Environmental protection: Silicone has a high environmental protection coefficient, is non-toxic and odorless, has stable chemical properties, is insoluble in water and any solvent (except strong alkali and hydrofluoric acid), and meets environmental protection standards such as the European Union.
Temperature resistance: Silicone has good temperature resistance, the processing temperature is about 180 degrees, and the normal temperature resistance range is about -40 to 230 degrees.
2. Thermal transfer effect
PVC thermal transfer trademark
Color and pattern: PVC thermal transfer trademark can achieve the printing of a variety of colors and patterns, but it may discolor or fade after long-term use.
Three-dimensional sense: Although PVC thermal transfer trademark can also produce a certain three-dimensional sense, it may be slightly inferior to silicone.
Silicone thermal transfer trademark
Color and pattern: Silicone thermal transfer trademark is bright, full and durable, and the pattern details are clear.
Three-dimensional sense: Silicone can achieve rich three-dimensional effects, making the trademark more layered and textured.
3. Application scope and durability
PVC thermal transfer trademark
Application scope: PVC thermal transfer trademark is suitable for occasions with low performance requirements or as a temporary logo.
Durability: Due to the poor temperature resistance and light and heat stability of PVC, discoloration, shedding and other problems may occur after long-term use.
Silicone thermal transfer trademark
Application range: Silicone thermal transfer trademarks are widely used in high-end clothing, sportswear, electronic products and other fields, especially in occasions where the clarity and integrity of the trademark need to be maintained for a long time.
Durability: Silicone thermal transfer trademarks have good wear resistance, scratch resistance and water resistance. Even after multiple washing and wearing, the trademark remains clear and intact.
4. Cost and safety
Cost: The cost of silicone raw materials is higher than that of PVC materials, so the price of silicone thermal transfer trademarks is usually higher than that of PVC thermal transfer trademarks.
Safety: Silicone is harmless to the human body and friendly to the environment; while PVC may release harmful gases during processing and use, which has a certain impact on the human body and the environment.
In summary, from the perspective of material properties, thermal transfer effect, application range and durability, as well as cost and safety, silicone thermal transfer trademarks show better performance than PVC thermal transfer trademarks in many aspects. However, considering the cost factor, PVC thermal transfer trademarks still have certain application value in some occasions where performance requirements are not high or in scenarios with limited budgets. Therefore, it is necessary to weigh the specific needs and scenarios when choosing.
