TPE Material Development Case: Application of ER75A3-DZYZ Black in E-cigarette Mouthpieces

Time of issue:2025-06-14

Material Selection Background

E-cigarette mouthpieces require materials that exhibit excellent elasticity, chemical resistance, food-grade safety, and a comfortable tactile feel. Thanks to its outstanding overall performance, TPE (thermoplastic elastomer) has become one of the ideal material choices for e-cigarette mouthpieces. The ER75A3 - DZYZ black TPE material has been specially designed and optimized in terms of hardness, elasticity, and aging resistance, enabling it to meet the stringent requirements for e-cigarette mouthpiece applications.

Material Performance Characteristics

  • Good elasticity and softness ER75A3 – The black TPE material from DZYZ has a suitable hardness (75A), ensuring that the vape mouthpiece provides a comfortable biting feel during use. It’s neither too hard, which could cause discomfort to the user, nor too soft, which would compromise its structural support.
  • Excellent chemical resistance E-liquid contains a variety of chemical substances. The ER75A3 - DZYZ black TPE material exhibits excellent chemical resistance, effectively resisting the corrosive effects of e-liquids and remaining resistant to deformation, discoloration, or performance degradation. This ensures the longevity and stability of electronic cigarette mouthpieces.
  • Food-grade safety standards This material meets food-grade safety requirements and does not release any harmful substances, ensuring the health and safety of users. This is especially critical for e-cigarette mouthpieces that come into direct contact with the human oral cavity.
  • Good machinability ER75A3 – DZYZ black TPE material is easy to process and mold, and can be manufactured into electronic cigarette mouthpieces of various shapes and sizes through multiple processing methods such as injection molding and extrusion, meeting the design requirements of different e-cigarette products. At the same time, it boasts high processing efficiency, helping to reduce production costs.

Application advantages

  • Enhance user experience Thanks to its excellent elasticity and softness, the e-cigarette mouthpiece made from ER75A3-DZYZ black TPE material provides users with a comfortable vaping experience and reduces the feeling of pressure on the mouth during prolonged use.
  • Ensure product quality The material’s chemical resistance and stability ensure that the e-cigarette mouthpiece maintains consistent performance even after prolonged contact with e-liquids, reducing the likelihood of quality issues and enhancing the product’s reliability and consistency.
  • Meet environmental protection requirements TPE material is recyclable and meets the current demand in the e-cigarette industry for environmentally friendly materials, helping to reduce environmental pollution.

Production process

When manufacturing e-cigarette mouthpieces, the ER75A3-DZYZ black TPE material is first loaded into an injection molding machine and melted by heating. The molten material is then injected into a pre-designed mold, where it cools and solidifies into the desired shape. After demolding and trimming, the finished e-cigarette mouthpieces are obtained through subsequent processing steps. During the production process, it is essential to strictly control parameters such as processing temperature, pressure, and time to ensure product quality and performance.

Market feedback

The e-cigarette mouthpieces made from ER75A3-DZYZ black TPE material have received positive feedback in the market. Users have praised their comfortable texture and durability, while e-cigarette manufacturers also note that the material’s stability and efficiency during processing help boost production efficiency and reduce costs. As a result, the application of ER75A3-DZYZ black TPE material in the e-cigarette mouthpiece sector has been further promoted and recognized.
