Silicone embossed debossed products and PVC soft embossing products are almost the same. How to distinguish them?
What is the difference between silicone and PVC soft rubber? Which one is better, silicone or soft PVC?
5 tips to teach you to identify whether it is silicone material or PVC?
The fifth tip is very important.
1 Touch,
Judging by the feel, silicone material is relatively softer and has better toughness, while PVC material is not as soft as silicone. PVC soft rubber products are relatively hard. Of course, the softness and hardness of the two materials can be adjust,
In terms of rebound strength, the rebound strength of silicone materials is relatively much better due to its good silicon molecular connection strength. However, due to the increased polydispersity of PVC materials, the rebound effect is naturally not as outstanding as that of silicone materials.
2, Look,
from the outside, the surface of silicone products is smooth and shiny, and the material is finer than PVC material.
In terms of color, there is basically no difference between the color of newly produced silicone products and PVC products. However, after being used for a period of time, PVC materials will stick to color, change color and turn yellow, especially when exposed to light. and hot environment, but this situation rarely occurs with silicone materials.
3 Smell,
silicone products are non-toxic and odorless, environmentally friendly, PVC soft rubber jewelry, compared to silicone products, will have a bit of smell.
4 Temperature resistance:
Silicone can withstand temperatures of -40-230℃, PVC soft rubber is not heat-resistant, between -15℃-80℃
5, Burn ,
Judging from the combustion reaction, silicone products will emit bright flames without producing a pungent odor, and will eventually leave a powdery residue;
When PVC is burned, it will soften and extinguish; and a large amount of black smoke will be emitted, accompanied by a pungent odor.
6 In terms of price,
the cost of silicone is higher than that of PVC, and silicone products have a long service life.

Compared with PVC 2D embosed deboosed product, silicone embossing products is not only has better anti-aging and high temperature resistance, but also has better viscosity and plasticity, and has a wider range of applications.
