TPU elastic band is a common elastic band, widely used in clothing, footwear, bags, medical equipment and other industries. It has good elasticity, durability and plasticity, and can maintain stable performance in different environments. This article will introduce the production process formula of TPU elastic band in detail and discuss its important role in various application fields.

TPU elastic band production process formula

1. Raw material selection

The main raw material of TPU elastic band is thermoplastic polyurethane (TPU) resin. TPU resin has excellent elasticity, wear resistance, oil resistance and chemical resistance, making it an ideal material for making elastic bands.

2. Formula ratio

The formula ratio of TPU elastic band can be adjusted according to different needs. Generally speaking, the content of TPU resin in the formula is between 80% and 90%, and an appropriate amount of auxiliary materials such as plasticizers, stabilizers, and pigments are added.

3. Processing technology

The production process of TPU elastic bands includes mixing, extrusion, stretching and cutting. Specific steps are as follows:

Mixing: Mix TPU resin with auxiliary materials such as plasticizers and stabilizers, and disperse them evenly through hot melt fusion.

Extrusion: Extrude the mixed material through an extruder to form a continuous strip of material.

Stretching: The extruded material is stretched through a stretching machine to achieve the required elasticity and stretch properties.

Cutting: Cut the stretched material as needed to obtain the required elastic band product.
