How to choose a black TPR manufacturer in Guangzhou

A bonding layer is formed at the interface between hard plastic and soft plastic.

Transparent grades are divided into transparent and semi-transparent series, each with multiple hardness levels; excellent transparency; smooth and soft surface; good yellowing resistance, tear resistance, and tensile strength; environmentally friendly; suitable for various transparent series products.

TPE high-transparency material has different product properties when applied to different areas. Thermoplastic elastomer, also called TPE material, transparent TPE not only has the processing properties of thermoplastic plastics but also has the physical properties of vulcanized rubber. This is the so-called advantageous combination of the advantages of plastics and rubber. Transparent TPE is widely used in people's life and production.

Greatly improves the overmolding adhesion between TPE soft plastic and hard plastic. False overmolding hardly involves the compatibility of the two materials; the overmolding of materials is achieved through mechanical force, through the design of the mold and product as well as surface treatment, and through snap-fit action, so that the soft plastic and hard plastic can be joined together.

TPE overmolding, as the name implies, is the process of overmolding TPE soft material onto other materials.

The thickness of the TPE/TPR overmolding layer. In most overmolding applications, a wall thickness range of 1.5-3.0mm will ensure good adhesion. If the TPE layer is too thin, injection molding is difficult, adhesion strength is low, and the hand feel is poor. If the TPE layer is too thick, on the one hand, the cost is higher; on the other hand, defects such as shrinkage and bubbles are prone to occur.

To prevent contamination of TPE raw materials and the presence of old materials or impurities in the screw and attachment depressions, especially materials with poor thermal stability, it is necessary to clean all parts with screw cleaning agent before use and after shutdown, so that they are free of impurities.

The commonly used processing methods include one-step molding with a two-color injection molding machine, or using a general injection molding machine with an overmolding mold for two-step injection molding. TPE overmolded products are generally handles, grips, and similar products. TPE soft material has a special comfortable touch sensation; the introduction of TPE material improves the grip and tactile feel of the product.

TPE material has good fluidity and is mainly processed by injection molding.

To achieve the matte appearance characteristic of thermosetting rubber surfaces, a relatively rough mold surface is required. Generally speaking, the rough surface generated by electrical discharge machining (EDM) of the mold cavity will produce an excellent workpiece appearance and make demolding relatively easy. Grinding methods such as steam blasting, sandblasting, or shot blasting, as well as chemical etching, can also be used to produce surfaces with different gloss and appearance.

Tpe is a classic aggregation-induced emission molecule, meaning it has no fluorescence in solution but exhibits strong fluorescence in the solid state. Therefore, transparent tpe materials also have important applications in fields such as organic optoelectronics.
