Silicone products and PVC products are more common in daily life. Both are environmentally friendly and safe products. They are widely used in daily necessities, packaging, fibers, etc., and the appearance is not much different, so many customers can’t distinguish what is silicone products and PVC products, let me tell you how to distinguish pvc products from silicone products.
Silicone products
The material of silicone is mainly composed of organic silicon and silicon atoms. The main material is siloxane, which is also a type of silicon chain compound with the largest amount and the most connections. The material is insoluble in fusion substances and does not mix with any Substances react and conflict, and can be left standing in any environment. The raw materials of silicone rubber products are mainly composed of silicone oil, siloxane, silicone resin and silane coupling agent. It is the safest and most environmentally friendly category in the rubber and plastic industry. Chemical materials.
PVC products
The full name of PVC products is polyvinyl chloride. It is mainly a polymer formed by the polymerization of compounds such as vinyl chloride monomer and azo compounds under high temperature. PVC materials can be synthesized into different types of products through polymer synthesis, and Both PVC gifts and silicone gifts are relatively common gifts in the market at present. The PVC material is mainly a white powdery amorphous substance with a density of about 1.3-1.5. The temperature resistance effect is low, and it will be automatically decomposed into hydrogen chloride at high temperature, and it will be automatically catalyzed and decomposed if it exceeds the temperature resistance range.
The difference between silicone products and PVC products:
1. From the appearance of the product, PVC products are rougher than silicone products, while the surface of silicone products is smooth and lustrous.
2. Judging from the hand feel, silicone products are soft, with good toughness and elasticity. PVC soft rubber is relatively less hard, and both softness and hardness can be adjusted, but PVC has no toughness.
3. PVC materials include ordinary materials and environmentally friendly materials, also known as ATBC-PVC, while silica gel can pass ROHS certification and is environmentally friendly.
4. Silicone products are generally made more transparent, with less burning smell, and the product is in powder form, while PVC products will turn black after being burned, and the smell is unpleasant when burned.
5. Silicone products are more resistant to heat and cold than PVC products. Silicone products can be heated in a microwave oven, but PVC cannot.
To sum up, silicone products can be distinguished from PVC products in terms of product appearance, feel, environmental certification, and performance.
