PVC material VS Silicone material

PVC material is not silicone material, they are two different materials. The full name of PVC is Polyvinylchloride, and the main ingredient is Polyvinyl chloride. PVC is an amorphous white powder with poor stability to light and heat. Stabilizers must be added in practical applications to improve the stability to heat and light. PVC used to be the world’s largest production of universal plastic, widely used.

The silicic acid gel is one of the highly active adsorbent material. Silica gel is mainly composed of silica, which has stable chemical properties and does not burn. Silicon raw material is a transparent or milky granular solid, with an open porous structure, strong adsorption, adsorption of a variety of substances. Silica gel can be reused after regeneration.

What are the advantages of silicone products and PVC products? What are the differences in performance and usage?

The characteristic of PVC soft rubber
Low liquidity: PVC is an amorphous material with a low moisture absorption rate and poor liquidity. In order to improve the fluidity and prevent bubbles, PVC material can be dried in advance.
Good chemical stability: PVC is a kind of flame retardant, it has good chemical stability. At the same time, its material characteristics also include high strength, high stiffness, and high hardness.
Strong corrosion resistance: PVC is most suitable for chemical industry corrosion protection equipment. PVC is easy to process as it is good electrical insulation.

The characteristic of Silicone
Temperature resistance: Silicon products have high thermal stability, and the chemical bonds of molecules do not break or decompose under high temperatures. Silicone is resistant to high and low temperatures and can be used over a wide range of temperatures.
Long Service life: Silicone products are not easily broken down by ultraviolet light and ozone. Silicon has better thermal stability, radiation resistance and weather resistance than other polymer materials. The service life of silicon in a natural environment can reach several decades.
Electrical insulation: Silicon products have good electrical insulation. Their electrical performance is little affected by temperature and frequency. Silicon also has excellent water repellency, which is the high reliability for electrical equipment in wet conditions.

The difference between PVC rubber and silicone gel
Different in material: PVC materials include common materials and environment-friendly materials, also known as ATBC-PVC, while silica gel can be certified by ROHS, which is environmentally friendly.
Different in character: Silicone products are more cold-resistant and more heat-resistant than PVC products. Tableware made of silicone can be heated in a microwave, while PVC can’t.
Different outside: From the appearance, PVC products are rougher than silicone products, silicone products have a smooth and shiny surface.
Different in touching: According to the hand feeling, the silicone product is soft with good toughness and elasticity, while the PVC soft rubber is relatively less hard. The softness and hardness of both can be adjusted, but the PVC does not have tenacity.
Different in the cost: The raw material price of PVC products is low, which is made of synthetic materials. Silica gel is more expensive than PVC products in production and manufacturing.

From the above differences, we can see that silicone is safer than PVC, which is more suitable for food and medicine materials. PVC products have a greater price advantage, more suitable as promotional gifts and other materials. It is of great importance to choose a safe and reliable PVC manufacturer who does not add harmful substances to your PVC products.
