What are the differences between silicone, TPU, and PC materials?
1. Different flexibility and endurance

The flexibility and durability of the maintenance shell mainly refer to the property that the maintenance shell is not easily broken after being subjected to force deformation. The flexibility and durability of the maintenance shell can be said to be the biggest difference in appearance and feel between silicone, TPU, and PC raw materials.

2. The silicone sleeve is very soft

The maintenance sleeve made of silicone material is usually soft in texture, with good tensile strength and a slightly smooth feel. If the high tensile material inside the silicone increases too little, it can easily break. How do you know its high tensile strength? Pull the product with hand light and force. If there is a phenomenon of turning white in the product, the high tension is too low. If there is a slight turning white or no turning white in the product, it is considered a qualified product.

3. The soft and hard properties of TPU are between rubber and plastic, and the hardness range of TPU is appropriately wide. After modifying the ratio of each responsive component of TPU, products with different hardness can be obtained. With the increase of hardness, the products still adhere to excellent elasticity and wear resistance. The well-known wear resistance, tear resistance, and flexural strength are all excellent; High tensile strength, high elongation, and one level lower long-term compression deformation rate are all obvious advantages of TPU.

4. PC maintenance shell has strong resistance

PC (polycarbonate) itself is a strong and tough thermoplastic resin. The PC raw material has strong impact resistance, excellent strength and resistance. Whether it is under heavy pressure or regular impact, as long as you don't try to hit it with a stone, it meets the requirements of long life and high transparency. However, its appearance is relatively simple and scratched.

5. Different forming processes

After selecting the raw materials, it is time to start making molds. Making molds is commonly referred to as mold making, which is the tool set that forms the product design. Good molds often use complex processes during the production process, and the machines used are generally expensive and advanced (good slow wire cutting machines require over 1 million yuan). Therefore, the accuracy of the molds produced is also very high. Some protective covers may look very exquisite, but in fact, in addition to the clever design of the cover itself, it also depends on the manufacturing process of the mold. Due to different raw materials, the forming process of each protective sleeve is also different.

6. The technical properties of silicone materials are different from those of TPU and PC materials

Silicone molding technology uses vulcanization molding

This technology utilizes the temperature and pressure of an hydraulic press to vulcanize and shape products using a mold. This technology is relatively low in cost, high in yield, and widely used for comparison. It is mostly used for monochromatic silicone products. It can also be used for dual color and dual hardness products or multi color and multi hardness products, but the structure of the product is not sensitive and limited. Silicone molds are made by cutting pieces of silicone material from top to bottom, placing them inside the mold, heating and pressurizing them to make the product.
