How to choose Fujian rubber TPE manufacturers

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

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 more difficult, adhesion strength is low, and hand feel is poor. If the TPE layer is too thick, on one hand costs are higher, on the other hand defects such as shrinkage and bubbles may occur.

Olefin-based transparent TPE has good weather resistance and ozone resistance, so it is called the fastest developing variety of TPE, and it is mainly used as a rubber material in fields such as automotive and home appliances.

Greatly improves the overmolding adhesion between TPE soft rubber and hard plastic. False overmolding hardly involves the compatibility of the two materials; the overmolding is achieved through mechanical force, mold and product design, surface treatment, and embedding action, so that the soft rubber and hard plastic are joined together.

TPE overmolding injection generally uses a two-shot injection molding process, that is, the injection-molded hard plastic part is fixed in the overmolding mold,

To prevent contamination of TPE raw materials and the presence of old materials or impurities in screw and attachment recesses, especially for materials with poor thermal stability, all parts should be cleaned with screw cleaner before use and after shutdown to ensure no impurities adhere.

SEBS is the product of hydrogenation of SBS. SEBS has a saturated molecular structure, which gives SEBS very different characteristics. It has the necessary aging resistance, yellowing resistance and other properties required to produce transparent TPE, and also contributes to excellent high temperature resistance and corrosion resistance. Only then is transparent TPE manufactured.

Then, at a suitable temperature, the TPE soft rubber is injection molded onto the hard plastic part, and after cooling, the product is obtained. The injection temperature for overmolding depends on the hard plastic material being overmolded.

Why is TPE material a good choice for toy dolls? Thermoplastic elastomer TPE soft compounds are increasingly used in the toy industry. In the toy application field,

Transparent TPE is used in appliance casings, handles, grips, etc. It exhibits very good hand feel, is anti-slip and labor-saving, easy to color and process, and offers a wide design space.

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

Traditional soft PVC material and TPR material, with their good environmental protection, safety, non-toxicity and other characteristics, are increasingly welcomed and trusted by consumers. Every industry has its own corresponding standards; as far as the toy industry is concerned, it also has its own special industry standards.
