TPU elastic band, also known as TPU transparent elastic band or Mobilon tape, is a kind of high – elasticity elastic band made of thermoplastic polyurethane (TPU). Here is a detailed introduction:
Material Characteristics
- High Elasticity and Strong Resilience: TPU has excellent elasticity. The elongation at break can reach more than 50%, and it can quickly return to its original shape after being stretched, avoiding garment deformation. It is especially suitable for parts that need frequent stretching and contraction, such as cuffs and collars.
- Durability: It has the characteristics of wear – resistance, water – wash resistance, yellowing resistance and aging resistance. It can withstand multiple washings and extreme temperatures ranging from – 38℃ to 138℃, with a long service life.
- Environmental Friendliness: TPU is a non – toxic and harmless environmental protection material, which meets the export standards of Europe and America. It can be incinerated or naturally decomposed after being buried without polluting the environment.
Advantages Compared with Traditional Rubber or Latex Elastic Bands
- Superior Material Properties: The wear – resistance, cold – resistance and oil – resistance of TPU are much higher than those of ordinary rubber.
- Better Elasticity: Its elasticity is better than that of traditional rubber bands. It has a higher rebound rate and is not easy to relax after long – term use.
- Environmental Protection Advantage: Traditional rubber is difficult to degrade, while TPU can be recycled or naturally decomposed, which is more in line with the current environmental protection requirements.
Main Application Areas
- Clothing Industry: It is widely used in T – shirts, masks, sweaters and other knitted products, bras and women’s underwear, swimwear, bathrobe sets, tight – fitting clothes and close – fitting underwear, sports pants, baby clothes and other clothing items that require elasticity. For example, it can be used in the cuffs, collars, hems and other parts of clothing to provide elasticity and fixation.
- Home Textiles: It can be used in some home textile products that need elasticity, such as bedspreads.
Technical Parameters
- Common Width: Usually 2mm – 30mm wide.
- Thickness: 0.1 – 0.3mm.
- Rebound Elongation: Generally, the rebound elongation can reach 250%, and the Shore hardness is 7. Different types of TPU elastic bands may have some differences in specific parameters.
Production Process and Quality Standards
TPU elastic bands are usually made by extrusion process with imported raw materials such as German BASF TPU. During the production process, strict quality control is carried out to ensure that the product has stable performance, such as uniform distribution of fine frosted particles, smooth surface, no stickiness, and smooth sewing without needle – blocking and breaking. At the same time, it must meet the relevant environmental protection and quality standards, such as the European Union’s ITS and OKO – level environmental protection and non – toxic standards.
