How to choose a smart wristband TPE manufacturer in Beijing

In the elastomer industry, TPE usually refers to a composite functional material modified from SEBS.

High-transparency TPE materials have different product properties in different applications. Thermoplastic elastomer is also called TPE material. Transparent TPE not only has the processing properties of thermoplastics but also the physical properties of vulcanized rubber. This is the so-called advantageous combination of plastic and rubber, and transparent TPE is widely used in people's daily life and production.

The wall thickness of TPE parts should be as uniform as possible to achieve the best molding cycle. The transition between different wall thicknesses should be gradual to reduce flow-related problems such as gas marks and bubbles.

TPE elastomer soft rubber has excellent comprehensive properties and is the most commonly used soft rubber material for overmolding, insert molding, and two-shot molding.

In TPE overmolding (two-shot injection), the key point is to ensure good adhesion between TPE and the substrate materials such as PP, ABS, PC, PA, etc. To achieve good adhesion between TPE and the substrate,

SEBS is the product of hydrogenation of SBS. SEBS has a saturated molecular structure, which leads to its distinct characteristics. It has the necessary aging resistance, yellowing resistance, and other properties required for producing transparent TPE, and also contributes to excellent high-temperature resistance and corrosion resistance. Thus, transparent TPE is manufactured.

The transparent grade includes transparent and semi-transparent series, each with various hardness levels; excellent transparency; smooth and soft surface; good anti-yellowing property, tear resistance, and tensile strength; meets environmental requirements; suitable for various transparent series products.

According to the principle of chemical similarity and compatibility, the key is that TPE and the substrate should have similar polarity, allowing molecular chain-level fusion between TPE and the substrate.

The temperature in the feeding zone should be set quite low to avoid blockage of the feed inlet and allow entrained air to escape.

Transparent TPE is used in stationery, sports equipment, etc. It has good UV resistance, chemical resistance, and is easy to color and process.

Transparent TPE, specifically, is a thermoplastic elastomer, while TPR is translated from English and strictly speaking is called thermoplastic rubber. This is the most basic difference. TPE is generally modified from SEBS base material, while TPR is modified from SBS base material.

To change the mixing state, the temperature in the transition zone should be set above the melting point of the masterbatch, so as to alter the mixing state when using the masterbatch. The temperature near the nozzle should be set close to the required melting temperature.
