The difference between TPU and silicone (which is better between tpu and silicone)

The difference between tpu and silica gel (which is better)? This column through the difference between silicone and meat, the difference between soft rubber and silicone, to make the following answers hope to help you.

TPU (thermoplastic polyurethane) and silica gel (silicone rubber) are two common elastic materials, but there are some differences in their properties and applications. This article will give you a detailed analysis of the characteristics and differences between TPU and silica gel to help you better understand the two materials.

1. Material composition:

TPU is a polyurethane material consisting of a polyester or polyether based chain with polyurethane. It has unique elasticity and wear resistance.

Silica gel is an elastic material made of silicon raw materials, the main component is silicon oxygen chain (Si-O). Silica gel is characterized by softness, high temperature resistance and chemical stability.

2. Physical properties:

TPU has high elasticity and wear resistance, similar to rubber. It can withstand long periods of use and friction without losing its elasticity.

Silica gel has excellent softness, elasticity and high temperature resistance. It can maintain stable performance over a wide temperature range, with good weather resistance and corrosion resistance.

3. Processing method:

TPU is a thermoplastic material that can be molded by thermoplastic processing methods, such as injection molding, extrusion, etc. This allows TPU to have high flexibility and plasticity in the manufacturing process.

Silicone is usually processed by liquid silicone injection molding or rolling molding. Due to its special physical and chemical properties, silicone requires special handling and curing steps during processing.

4. Application field:

TPU is commonly used in shoe soles, clothing, auto parts, electronic products and other fields. Its excellent elasticity and wear resistance make it ideal for many applications.

Silicone is often used to make seals, keyboards, baby pacifiers, Medical equipment, protective covers for electronic products, etc. Its high temperature resistance and chemical stability make it have important application value in special environment.

5. Price and Availability:

TPU has a relatively low production cost and is easily available on the market. It is widely used in many consumer and industrial fields.

The difference between TPU and silicone (tpu and silicone which is good) relevant information is introduced here, the difference between silicone and meat, the difference between soft rubber and silicone, I hope to help you.
